IBX Change Log version (2.2-0) Mon, 26 Feb 2018 11:49:23 +0000
|
2 |
|
3 |
NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
|
4 |
AVOID DUPLICATE PPU ERRORS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
|
5 |
RELEASE.
|
6 |
|
7 |
NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
|
8 |
|
9 |
1. IBExtract: Identity columns - add additional check for null column for generator name.
|
10 |
|
11 |
2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
|
12 |
The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
|
13 |
information). However, this is also a very useful mechanism for returning updated computed by
|
14 |
column values. Values returned as a result of executing an Insert or Update statement
|
15 |
replace existing values in the current row for each corresponding column.
|
16 |
|
17 |
Previously, if a dataset's select query included read only (computed by) fields then
|
18 |
an automatic row refresh was performed after an insert or update query had been processed,
|
19 |
irrespective of the setting of the "ForcedUpdates" property. This has changed such
|
20 |
that an automatic refresh is no longer performed if an insert or update query contains
|
21 |
a returning clause that updates one or more fields on the current row. A full row
|
22 |
refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
|
23 |
field values and the select query contains read only fields. Use of Insert/update
|
24 |
returning should be significantly more efficient than executing a refresh query.
|
25 |
|
26 |
This behaviour change is intended to be backwards compatible and there should be no need to change
|
27 |
existing programs, other than to improve performance by using the new capability.
|
28 |
|
29 |
3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
|
30 |
they are called when the dataset row is being deleted, there is no value in
|
31 |
updating the current record from the query result. Instead, a new event handler
|
32 |
"OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
|
33 |
an OnDeleteReturning event handler is provided then it is called with the IResults returned
|
34 |
by the query. The event handler can then interrogate the query results and
|
35 |
perform whatever action is necessary. For example to confirm, to the user,
|
36 |
the deletion of a row with the returned values.
|
37 |
|
38 |
4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
|
39 |
any Computed By or Identity Columns. The IBTables example has been updated to
|
40 |
illustrate the computation of the employee Full Name on update.
|
41 |
|
42 |
5. TIBTable: The GeneratorField property is now published.
|
43 |
|
44 |
6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
|
45 |
When InsertSQL is generated, the Identity columns are not included in the list of values to
|
46 |
be inserted. A RETURNING clause is added to the insert statement to return the value of
|
47 |
each Identity column after the insert is executed.
|
48 |
|
49 |
7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
|
50 |
Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
|
51 |
Insert..Returning clause.
|
52 |
|
53 |
8. TIBGenerator: small performance improvement by not preparing query each time
|
54 |
a new value is generated.
|
55 |
|
56 |
9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
|
57 |
|
58 |
10. Property editors will now sync table name to a System Table when "Include System
|
59 |
Tables" is selected and the query is for a System Table.
|
60 |
|
61 |
11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
|
62 |
values are no longer converted to milliseconds from TDateTime and then back again
|
63 |
to TDateTime (the conversion to milliseconds is the default TDataset approach).
|
64 |
|
65 |
12. Property Editors handling of Stored Procedures.
|
66 |
* Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
|
67 |
which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
|
68 |
query).
|
69 |
* Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
|
70 |
|
71 |
13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
|
72 |
can be used to select a package. If non-empty, the stored procedure name is
|
73 |
expected to be a stored procedure defined in the specified package and the
|
74 |
generated SQL will be as required for a stored procedure located in a package.
|
75 |
|
76 |
14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
|
77 |
a "Package Name" drop down box to allow selection of a Firebird 3 Package from
|
78 |
which a stored procedure can be selected. With no package name selected, non-package
|
79 |
stored procedures are listed.
|
80 |
|
81 |
15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
|
82 |
for password on reconnect.
|
83 |
|
84 |
16. TIBDatabase: use IAttachment for connection default character set id, code page
|
85 |
and character set name.
|
86 |
|
87 |
17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
|
88 |
DB info lookups"
|
89 |
|
90 |
18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
|
91 |
|
92 |
19. Add a property Editor for TIBUpdate.RefreshSQL.
|
93 |
|
94 |
20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
|
95 |
parameters. This stops an exception being raised when the field cannot be
|
96 |
located in the record buffer.
|
97 |
|
98 |
21. Property Editors now automatically include System Tables when opened and when the query table
|
99 |
is a System Table.
|
100 |
|
101 |
22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
|
102 |
This avoids errors due to a stale SQRB or SRB being used for the next query.
|
103 |
|
104 |
23. IBServices: Service attach parameters now include "expected_db". This is used to
|
105 |
add the SPB item isc_spb_expected_db. This names a database using
|
106 |
an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
|
107 |
database. examples/services re-written to illustrate use of "expected_db".
|
108 |
|
109 |
24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
|
110 |
This avoids truncated backups when the server returns a timeout (busy) response.
|
111 |
|
112 |
25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
|
113 |
|
114 |
26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
|
115 |
databasenames. These are respectively expanded to the local system's temp directory
|
116 |
(including trailing delimiter) or to a prescribed data directory (including
|
117 |
trailing delimiter). Under Unix systems the data directory is a hidden directory
|
118 |
in the user's home directory. The hidden directory name is either the string returned
|
119 |
from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
|
120 |
Under Windows, the directory is the same as the Data Directory as decribed
|
121 |
above but instead prefixed by the User's application data path. These may be
|
122 |
used to improve application portability for Personal Databases.
|
123 |
|
124 |
27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
|
125 |
this has not worked for a long time and is not useful either. FieldDefs should be
|
126 |
managed using the Fields Editor as with any other dataset. To access the fields
|
127 |
editor for a TIBTable component, double click on the component. The fields editor
|
128 |
is then displayed.
|
129 |
|
130 |
28. TIBDatabaseInfo: new properties/function
|
131 |
* DateDBCreated (returns date/time database created)
|
132 |
* TransactionCount (returns no. of active transactions)
|
133 |
* GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
|
134 |
* PagesFree (Firebird 3 or later)
|
135 |
* PagesUsed (Firebird 3 or later)
|
136 |
* Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
|
137 |
* EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
|
138 |
|
139 |
29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
|
140 |
|
141 |
30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
|
142 |
|
143 |
31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
|
144 |
the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
|
145 |
|
146 |
32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
|
147 |
in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
|
148 |
firing during backup and restore.
|
149 |
|
150 |
33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
|
151 |
for verbose output using the new property "StatisticsRequested".
|
152 |
see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
|
153 |
|
154 |
34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
|
155 |
|
156 |
35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
|
157 |
palette. This uses the online validation feature added in Firebird 2.5. The
|
158 |
services's properties enable inclusion/exclusion of tables and indexes using
|
159 |
regular expressions. See.
|
160 |
https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
|
161 |
|
162 |
36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
|
163 |
option on a database.
|
164 |
|
165 |
37. TIBCustomService: Assign method implemented to allow copying of service login
|
166 |
context between service API components. "Detach" method now only detaches
|
167 |
service when last reference to the service interface detaches. Tidy up of
|
168 |
code for SetActive and Attach methods including password hiding.
|
169 |
|
170 |
38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
|
171 |
and used to determine the auth method and protocol used for the connection.
|
172 |
|
173 |
39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
|
174 |
a Create Database Statement generated by IBX.
|
175 |
|
176 |
40. All IBServices now have an additional published property "PortNo". This may
|
177 |
be set to a non-standard port number when necessary. If zero then the default
|
178 |
port number is used.
|
179 |
|
180 |
41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
|
181 |
and not just the mouse.
|
182 |
|
183 |
42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
|
184 |
|
185 |
43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
|
186 |
image index and selected image index for each node to be set from a database field.
|
187 |
|
188 |
44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
|
189 |
then database schema includes grants to all users. If not present then the
|
190 |
only user grants included are those to User PUBLIC.
|
191 |
|
192 |
45. TIBTreeView: performance improvement. When expanding include both expanded node
|
193 |
and child nodes in dataset.
|
194 |
|
195 |
|
196 |
IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
|
197 |
|
198 |
1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
|
199 |
changes.
|
200 |
|
201 |
2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
|
202 |
Bug could result in truncated multi-byte character set values.
|
203 |
|
204 |
3. Changes consequential on moving fbintf character set utility functions from
|
205 |
IFirebirdAPI to IAttachment.
|
206 |
|
207 |
4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
|
208 |
|
209 |
5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
|
210 |
results in autocomplete ignoring prefix text.
|
211 |
|
212 |
6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
|
213 |
entering a new name into the text box.
|
214 |
|
215 |
7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
|
216 |
Firebird rather than recomputing it.
|
217 |
|
218 |
8. Property Editor positioning tidy up: All IBX Property editors should now be
|
219 |
screen centre. Previously some were "poDesigned" which may be inappropriate
|
220 |
for multi monitor desktops.
|
221 |
|
222 |
10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
|
223 |
|
224 |
11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
|
225 |
a transaction and always reset the object.
|
226 |
|
227 |
12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
|
228 |
|
229 |
13. TIBXScript: Allow for override of database filename in Create Database statements.
|
230 |
|
231 |
14. IBLocaldb: Support initialisation of the database from an SQL script in addition
|
232 |
to a gbak format archive.
|
233 |
|
234 |
15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
|
235 |
|
236 |
16. IBLocaldb: Drop database if error creating an empty database.
|
237 |
|
238 |
17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
|
239 |
unless selected node not in current dataset.
|
240 |
|
241 |
18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
|
242 |
to TIBCustomService, and IBlocalDB code tidy up.
|
243 |
|
244 |
19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
|
245 |
behaviour due to uninitialised variable.
|
246 |
|
247 |
20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
|
248 |
integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
|
249 |
|
250 |
21. IBSQL: When Database changed ensure that all resources are freed.
|
251 |
|
252 |
22. IBCustomDataset: When database changed ensure that queries an unprepared.
|
253 |
|
254 |
23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
|
255 |
* Line Wrap on SQL Token boundaries (on user command)
|
256 |
* auto-complete table names in drop down list of table names
|
257 |
* Double click on tablename or field name adds to SQL text
|
258 |
|
259 |
24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
|
260 |
|
261 |
25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
|
262 |
TVariantArray. Seems to avoid memory corruption in Windows (probably a
|
263 |
workaround for a problem in fpc 3.0.4 win64).
|
264 |
|
265 |
26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
|
266 |
|
267 |
27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
|
268 |
|
269 |
IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
|
270 |
|
271 |
1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
|
272 |
include remote system name.
|
273 |
|
274 |
2. TIBExtract: No longer include comment header and COMMIT statement for empty
|
275 |
tables when data included in output.
|
276 |
|
277 |
3. Profiling: IBSQL now has conditional compilation flags to enable query performance
|
278 |
and timing information to be written to stdout. This may be used to locate
|
279 |
performance bottlenecks.
|
280 |
|
281 |
4. SQLParser: only call "OnChanging" event handler when value is different.
|
282 |
|
283 |
5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
|
284 |
|
285 |
6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
|
286 |
that BindFields is called when the query is next activated. Avoids FieldName
|
287 |
not found error.
|
288 |
|
289 |
7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
|
290 |
purpose and allows the programmer to define any action they want for Update, Insert
|
291 |
or Delete. This may be complex SQL (similar to a Trigger), application specific
|
292 |
filtering of updates, or use of statements such as Grant or Revoke instead of
|
293 |
normal DML. See User Manual for more information.
|
294 |
|
295 |
IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
|
296 |
|
297 |
1. TIBEvents: Fix uninitialised variable that could result in lost events.
|
298 |
|
299 |
2. TIBExtract: Added support for FB3 "USAGE" privilege.
|
300 |
|
301 |
3. TIBExtract: data formatted as Charset set "octets" is now output using
|
302 |
hexadecimal notation.
|
303 |
|
304 |
4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
|
305 |
using a simple XML format.
|
306 |
|
307 |
5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
|
308 |
grants to these objects.
|
309 |
|
310 |
6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
|
311 |
dependency problems restoring complex databases.
|
312 |
|
313 |
7. TIBXScript: This component has been restructured to allow for the processing of
|
314 |
embedded XML in INSERT statements and to support interactive sources in addition
|
315 |
to non-interactive data sources such as files.
|
316 |
|
317 |
8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
|
318 |
|
319 |
9. TIBXScript: ISQL compatiable Set statements are now supported:
|
320 |
SET SQL DIALECT
|
321 |
SET TERM
|
322 |
SET AUTODDL
|
323 |
SET BAIL
|
324 |
SET ECHO
|
325 |
SET COUNT
|
326 |
SET STATS
|
327 |
SET NAMES <character set>
|
328 |
|
329 |
10. IBVersion unit added to hold current IBX Version Number information.
|
330 |
|
331 |
11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
|
332 |
and domain definitions.
|
333 |
|
334 |
12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
|
335 |
fully supported.
|
336 |
|
337 |
13. TIBExtract: when a database dump includes data, the generator values are now also set.
|
338 |
|
339 |
14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
|
340 |
|
341 |
IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
|
342 |
|
343 |
See also doc/IBX4LazarusGuide.pdf for important information on
|
344 |
upgrading to IBX2.
|
345 |
|
346 |
1. Size property of TIBStringField is now the width in characters of the field
|
347 |
and not the byte length. This applies only to multi-byte character sets such
|
348 |
as UTF8. The original approach aligned with TStringField. However, the TStringField
|
349 |
code is not recognised as a bug and hence this change to align the behaviour.
|
350 |
The TStringField change is expected in fpc 3.2.0.
|
351 |
|
352 |
2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
|
353 |
true (default) then Size property value saved in the lfm is ignored. Size is
|
354 |
always set from the dynamic information read from the database. It is unclear
|
355 |
why anyone would want to override this and set Size to false.
|
356 |
|
357 |
3. ibxscript: should now handle correctly a Case..End statement within a procedure
|
358 |
block.
|
359 |
|
360 |
4. IBDatabase: new property - CreateIfNotExists. If true and database does not
|
361 |
exist when an attempt is made to connect to it (run time only) then an attempt
|
362 |
is made to create the database.
|
363 |
|
364 |
5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
|
365 |
has been successfully created as a result of a call to CreateDatabase or when
|
366 |
creating a database after it was found not to exist.
|
367 |
|
368 |
6. DBControlGrid: a race condition could result in the wrong row image being
|
369 |
written to the cache. This has been avoided by a trip round the message
|
370 |
loop before rendering the row image.
|
371 |
|
372 |
7. DBControlGrid: It is strongly recommended not to open the source DataSet for
|
373 |
a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
|
374 |
known to risk corrupt rendering of row images when the control is first
|
375 |
displayed. If necessary use "Application.QueueAsyncCall" to delay opening
|
376 |
of the dataset (see DBControlGrid examples) until the Form's Window has been created.
|
377 |
|
378 |
8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
|
379 |
a TDateEdit control located on an editor panel.
|
380 |
|
381 |
9. TIBExtract: brought up-to-date plus many bug fixes.
|
382 |
|
383 |
10. DBControlGrid: Removed memory leak when updating rows.
|
384 |
|
385 |
11. TIBCMLocalDBSupport: fixed invalid free on upgrade.

IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
|
388 |
|
389 |
1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
|
390 |
when target codepage is CP_NONE. This is a workaround for
|
391 |
http://bugs.freepascal.org/view.php?id=30622.
|
392 |
|
393 |
2. DBLog option removed from TIBStatisticalService - not supported by server
|
394 |
since Firebird 1.5.
|
395 |
|
396 |
3. ibxscript: An error is no longer generated for "on commit preserve rows" or
|
397 |
similar.
|
398 |
|
399 |
4. IBCodePage: updated mapping between codepages and character id.
|
400 |
|
401 |
5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
|
402 |
Firebird. Character sets with a char width of two are not UTF16.
|
403 |
|
404 |
6. Strings received from the database are now always transliterated into UTF8
|
405 |
regardless of the database character set or connection character set. This
|
406 |
is for compatibility with the LCL.
|
407 |
|
408 |
IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
|
409 |
|
410 |
1. IBBlob: Defer reading of blob until read method called. This avoids having to
|
411 |
read in an entire blob just to get the size of the blob. General performance
|
412 |
improvement when opening datasets containing blobs.
|
413 |
|
414 |
2. Clearing a Blob now sets the corresponding field's modified flag.
|
415 |
|
416 |
3. IBLookupCombo: When not performing auto-complete, original query sort order
|
417 |
is now used.
|
418 |
|
419 |
4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
|
420 |
determined.
|
421 |
|
422 |
5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
|
423 |
|
424 |
6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
|
425 |
lazarus 1.6.0
|
426 |
|
427 |
7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
|
428 |
compilation error.
|
429 |
|
430 |
IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
|
431 |
|
432 |
1. No character set specified for connection: when a text blob is retrieved, the
|
433 |
character set is determined by looking up the native character set using then
|
434 |
Firebird API. Otherwise a text mode blob is assumed to have the same character
|
435 |
set as the connection.
|
436 |
|
437 |
2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
|
438 |
for Login Dialog returing a change to the database path.
|
439 |
|
440 |
3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
|
441 |
to be changed from that given in the TIBDatabase/TIBServer component and for the
|
442 |
entered value to be saved on a project specific basis (design time only).
|
443 |
|
444 |
4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
|
445 |
column fieldname. If they are the same then it is acts as a look up for the KeyValue
|
446 |
Otherwise, it sets the column text to the selected ListField Value.
|
447 |
|
448 |
5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
|
449 |
column width.
|
450 |
|
451 |
6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
|
452 |
and a case insensitive search is requested.
|
453 |
|
454 |
7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
|
455 |
or column ListSource.
|
456 |
|
457 |
8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
|
458 |
unprepare) when closing and the text has not changed.
|
459 |
|
460 |
9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
|
461 |
Less likely to cause a cursor re-use error on Windows.
|
462 |
|
463 |
10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
|
464 |
Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
|
465 |
|
466 |
11. TIBTreeView: Guard against nil destination on record changed
|
467 |
|
468 |
12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
|
469 |
string type with the code page set to reflect the returned field encoding after
|
470 |
Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
|
471 |
earlier versions.
|
472 |
|
473 |
13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
|
474 |
will now result in transliteration to the code page specified for the Firebird driver
|
475 |
if the assigned string has a different code page. FPC 3.0.0 onwards only.
|
476 |
|
477 |
14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
|
478 |
is ignored and the lc_ctype value, when the database is opened, is set to align with
|
479 |
the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
|
480 |
platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
|
481 |
3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
|
482 |
the GETACP is used to determine the Windows code page.
|
483 |
|
484 |
15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
|
485 |
name used as the lc_ctype when the database was opened. Only valid while the
|
486 |
Database is connected.
|
487 |
|
488 |
16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
|
489 |
id that corresponds to the DefaultCharSetName.
|
490 |
|
491 |
IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
|
492 |
|
493 |
1. Unix: If Firebird Embedded Server shared object is loaded and a local database
|
494 |
path is given and database attach fails due to access permission issues on the
|
495 |
temp directory or security database, then the attach is retried with "localhost:"
|
496 |
prefixing the databasename. This should avoid problems when the database has to
|
497 |
be accessed by a local (e.g. classic) server and libfbembed is used.
|
498 |
|
499 |
2. Windows: revised search order for Firebird DLL:
|
500 |
i. The Firebird Embedded Server in the application Directory.
|
501 |
ii. If the FIREBIRD environment variable is set then the directory this
|
502 |
points to is searched for the FB Client DLL and then then underlying
|
503 |
"bin" directory.
|
504 |
iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
|
505 |
is used to locate the Firebird installation directory and the underlying
|
506 |
"bin" directory is searched for the FB Client DLL.
|
507 |
iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
|
508 |
are searched for the FB Client DLL.
|
509 |
v. The PATH Environment variable is used to search for the FB Client DLL.
|
510 |
vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
|
511 |
|
512 |
3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
|
513 |
See doc/readme.scriptengine and example applications.
|
514 |
|
515 |
4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
|
516 |
simplify the use of the embedded firebird server on both Linux and Windows platforms.
|
517 |
See dpc/readme.localdatabase and example applications.
|
518 |
|
519 |
5. IBDynamicGrid: Reordering on column header click should now also work for
|
520 |
dynamic columns.
|
521 |
|
522 |
6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
|
523 |
between incrementing/decrementing the lock count and signalling the event.
|
524 |
|
525 |
IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
|
526 |
|
527 |
1.3.2 was never formally released and only made available as beta copies.
|
528 |
|
529 |
1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
|
530 |
|
531 |
2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
|
532 |
|
533 |
3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
|
534 |
|
535 |
4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
|
536 |
i.e. when it is a calculated field
|
537 |
|
538 |
5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
|
539 |
This problem was due to a race condition between recalculating row heights and
|
540 |
determining which row was selected by the mouse click. The row height calculation
|
541 |
is now deferred by an extra trip round the message loop allowing the row to
|
542 |
be always calculated on the current grid layout rather than risking it being
|
543 |
calculated on the grid layout after the expanded row has been shrunk.
|
544 |
|
545 |
6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
|
546 |
Windows.
|
547 |
|
548 |
7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
|
549 |
These properties allow the (Firebird) character set name for the field and the max number of bytes per character
|
550 |
to be determined at runtime. See doc/readme.charactersets.html.
|
551 |
|
552 |
8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
|
553 |
TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
|
554 |
|
555 |
9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
|
556 |
TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
|
557 |
1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
|
558 |
|
559 |
Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
|
560 |
from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
|
561 |
implies no truncation.
|
562 |
|
563 |
10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
|
564 |
|
565 |
11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
|
566 |
(avoids "Not in Edit Mode" error).
|
567 |
|
568 |
12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
|
569 |
|
570 |
13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
|
571 |
DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
|
572 |
|
573 |
14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
|
574 |
|
575 |
15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
|
576 |
|
577 |
16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
|
578 |
|
579 |
17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
|
580 |
|
581 |
IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
|
582 |
|
583 |
1. OnCloseUp Event Handler added to TDBLookupProperties
|
584 |
|
585 |
2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
|
586 |
problem with row size when exception is called.
|
587 |
|
588 |
3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
|
589 |
|
590 |
4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
|
591 |
in a TCustomComboBox and ignores return key if in a TCustomMemo
|
592 |
|
593 |
5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
|
594 |
keyed in i.e. when autocomplete not performed
|
595 |
|
596 |
6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
|
597 |
console mode applications with all LCL required functions (builtin dialogs and
|
598 |
cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
|
599 |
not included in your project, IBX should compile and link with a console mode program.
|
600 |
See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
|
601 |
console mode application or the IDE will automatically assume that your
|
602 |
application is GUI based. Instead, you should include the ibexpressconsolemode package.
|
603 |
|
604 |
IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
|
605 |
to use the built in dialogs and cursor management. IBDialogs is
|
606 |
included by default if "ibexpress" is in your project source's "uses" clause.
|
607 |
This should be the case for all projects created through the IDE. This is why
|
608 |
you do not want to add the ibexpress package to console mode applications. The
|
609 |
ibexpressconsolemode package has been created to allow console mode programs
|
610 |
to avoid adding LCL dependencies when using IBX, while still having the
|
611 |
unit search paths set up correctly.
|
612 |
|
613 |
Existing users should check to ensure that the "ibexpress" unit is included in
|
614 |
each project's source file (*.lpr).
|
615 |
|
616 |
You may find that in order for the IDE to recognise that ibexpressconsolemode
|
617 |
exists, you have to first open the package in the IDE and then close it. This
|
618 |
adds it to the most recently accessed packages list. To make it permanently
|
619 |
available, add the package name to lazarus' staticpackages.inc file.
|
620 |
|
621 |
Thanks to Julio Jiménez for suggesting support of console mode.
|
622 |
|
623 |
7. SQL Parser can now accept quoted strings that include new lines
|
624 |
|
625 |
8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
|
626 |
of text on start of edit. This is particularly useful when tabbing to a
|
627 |
column and then inserting text.
|
628 |
|
629 |
9. New Examples provided for IB Services and ISQLMonitor.
|
630 |
|
631 |
10. Fix error when writing to blob streams that recorded only the last buffer
|
632 |
write in the blob stream. In most cases, this did not cause a problem as the
|
633 |
IB Blob Stream is written in a single write. However, with the TDBImage, write
|
634 |
of a graphic type prefix was lost which caused a problem when the image could
|
635 |
not be automatically recognised.
|
636 |
|
637 |
11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
|
638 |
already open" errors due to random numbers used for the cursor name being identical.
|
639 |
|
640 |
12. IBTable: corrected error that could result in an "Index out of bounds" error
|
641 |
when opening the table and the Primary Key is the last or only column in the
|
642 |
table. Thanks to Rick Hoover for the fix.
|
643 |
|
644 |
13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
|
645 |
of "UTF-8", and update list of available database character sets. Existing
|
646 |
users should check the current lc_ctype setting in their applications.
|
647 |
|
648 |
IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
|
649 |
|
650 |
1. Firebird Services: avoid List Index error when opening a service with an
|
651 |
empty Params property.
|
652 |
|
653 |
2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
|
654 |
Link now set up in Loaded method - avoids occasional failure to apply
|
655 |
SQL markup on initial open.
|
656 |
|
657 |
3. "Employees" example performance improvements when scrolling.
|
658 |
|
659 |
4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
|
660 |
TFrame. Force recaching of selected frame to avoid GTK race (results in a
|
661 |
random image cached).
|
662 |
|
663 |
5. DBControlGrid: Should now react to changes in panel height at run time.
|
664 |
|
665 |
6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
|
666 |
even when further rows exist.
|
667 |
|
668 |
7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
|
669 |
always be derived from panel height and setting this property can cause confusion.
|
670 |
Note for existing projects: to avoid a missing property error at run time,
|
671 |
each form using the DBControlGrid must be opened, updated and saved in the IDE
|
672 |
in order to remove the property value from the lfm.
|
673 |
|
674 |
|
675 |
IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
|
676 |
|
677 |
1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
|
678 |
call Prepare before setting parameter values.
|
679 |
|
680 |
2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
|
681 |
|
682 |
3. Code tidyup and more robust handling of dsql information result vector.
|
683 |
|
684 |
4. Support for centralised handling of transaction status changes. TIBTransaction
|
685 |
has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
|
686 |
and "AfterExecQuery". The first three are called after the same event is called
|
687 |
for an IBCustomDataSet descendent using the Transaction. The fourth is called
|
688 |
after a call to TIBSQL.ExecQuery, again using this transaction. These new events
|
689 |
enable monitoring of transaction status changes for a given transaction to be
|
690 |
handled in a single place. For example, when a change to the dataset occurs
|
691 |
an indicator can be set that shows the user that in order to save changes,
|
692 |
the transaction should be committed. Rather than doing this per dataset, this
|
693 |
can now be done per transaction.
|
694 |
|
695 |
5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
|
696 |
the dataset is scrolled. However, any changes to the current row are, by default,
|
697 |
discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
|
698 |
have a new property "DataSetCloseAction" that adds automatic posting of changes
|
699 |
on dataset close. If this property is set to dcDiscardChanges (default) then the
|
700 |
behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
|
701 |
then IBX will attempt to post any unsaved changes before the dataset is closed
|
702 |
(and after the BeforeClose event handler is called). The exception is when the
|
703 |
dataset is being closed as a result of a transaction rollback. In this case,
|
704 |
no action is taken and any unsaved changes are discarded. This avoids both
|
705 |
unnecessary overhead and the risk that a validation error may occur in the Post
|
706 |
raising an exception and thereby preventing a rollback.
|
707 |
|
708 |
6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
|
709 |
In earlier versions, the Display Width was set to the maximum byte width rather than the character
|
710 |
width. Display Widths are now corrected by dividing by the max byte width per character.
|
711 |
For UTF8 character sets, the byte width is four and hence the Display Width will be
|
712 |
the byte width divided by 4. The byte width of each character set is determined
|
713 |
dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
|
714 |
system table. (see also http://bugs.freepascal.org/view.php?id=27766).
|
715 |
|
716 |
7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
|
717 |
|
718 |
8. IBLookupComboEditBox: List should now always be restored to full list when the
|
719 |
control loses focus. Default Key press default interval reduced to 200ms.
|
720 |
|
721 |
9. DBControlGrid: Ensure that selection is changed to newly appended row, even
|
722 |
when dataset rows are less than visible rows.
|
723 |
|
724 |
10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
|
725 |
does not exist or DataSet is empty. More responsive on dataset open. New event
|
726 |
OnRestorePosition. Column sort disabled if no header row.
|
727 |
|
728 |
11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
|
729 |
while dataset state is dsInsert. Avoids posting errors.
|
730 |
|
731 |
12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
|
732 |
avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
|
733 |
|
734 |
13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
|
735 |
|
736 |
14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
|
737 |
to solve a specific problem. That is when the dataset cursor is moved (e.g. by
|
738 |
a grid mouse click and the current row is being edited or inserted. In this case, TDataset
|
739 |
always "posts" the current record regardless or whether or not it may be more appropriate
|
740 |
to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
|
741 |
"MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
|
742 |
as the first action of the "Post" method and allows the handler to convert the Post
|
743 |
into a Cancel if that is the appropriate action on moving to a different row. This is
|
744 |
achieved by returning with "CancelPost" argument set to true. Note that an exception could be
|
745 |
raised here, but it may still be more appropriate to validate a post and signal
|
746 |
a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
|
747 |
|
748 |
15. On Unix derived systems, the Firebird library name can now be given as a colon
|
749 |
separated list. Each library name on the list is tried in turn, in left to right
|
750 |
order with the first found being used as the firebird library. By default, on Linux,
|
751 |
the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
|
752 |
overidden by the FBLIB environment variable or the OnGetLibraryName function.
|
753 |
|
754 |
Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
|
755 |
then it will still attempt to access the database via the Firebird Server and will
|
756 |
require a username and password. If only the pathname is given, then the username
|
757 |
and password should be omitted and the unix file permissions are used to grant
|
758 |
access.
|
759 |

IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
|
761 |
|
762 |
1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
|
763 |
rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
|
764 |
that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
|
765 |
corresponds to a row of the linked DataSource. Any data aware control on the
|
766 |
replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
|
767 |
|
768 |
2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
|
769 |
When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
|
770 |
takes place during database access. This may be useful when there are performance issues with
|
771 |
the change of cursor. Setting the property to false suppresses the change of cursor.
|
772 |
|
773 |
3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
|
774 |
and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
|
775 |
Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
|
776 |
making all changes permanent immediately rather than when the transaction is explicitly
|
777 |
committed.
|
778 |
|
779 |
4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
|
780 |
using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
|
781 |
|

786 |
IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
|
787 |
|
788 |
1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
|
789 |
This is typically used during an "OnBeforeOpen" event handler to manipulate the
|
790 |
"Where" and "Having" clauses to implement user specified filters of arbitrary
|
791 |
complexity.
|
792 |
|
793 |
2. A new Component Palette entry "Firebird Data Controls" is now available. This has
|
794 |
three new data aware controls dependent on IBX and which make use of the SQL Parser.
|
795 |
These are:
|
796 |
|
797 |
- TIBLookupComboEditBox
|
798 |
- TIBDynamicGrid
|
799 |
- TIBTreeview
|
800 |
|
801 |
TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
|
802 |
of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
|
803 |
to revise the available list and restrict it to items that are prefixed by the
|
804 |
typed text (either case sensitive or case insensitive). Autoinsert allows a
|
805 |
newly typed entry to be added to the list dataset and included in the available
|
806 |
list items.
|
807 |
|
808 |
TIBDynamicGrid is a TDBGrid descendent that provides for:
|
809 |
- automatic resizing of selected columns to fill the available row length
|
810 |
- automatic positioning and sizing of a "totals" control, typically at the
|
811 |
column footer, on a per column basis.
|
812 |
- DataSet resorting on header row click, sorting the dataset by the selected column.
|
813 |
A second click on the same header cell reversed the sort order.
|
814 |
- Support for a "Panel Editor". That is on clicking the indicator column, the row
|
815 |
is automatically expanded and a panel superimposed on it. The panel can have any
|
816 |
number of child controls, typically data aware controls with the same datasource
|
817 |
as the grid allowing for editing of additional fields and more complex editors.
|
818 |
- Reselection of the same row following resorting.
|
819 |
- A new cell editor that provides the same functionality as TIBLookupComboEditBox.
|
820 |
Its properties are specified on a per column basis and allows for one or more
|
821 |
columns to have their values selected from a list provided by a dataset.
|
822 |
Autocomplete and autoinsert are also available. The existing picklist editor
|
823 |
is unaffected by the extension.
|
824 |
|
825 |
TIBTreeView is a data aware TCustomTreeView.
|
826 |
|
827 |
3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
|
828 |
zero scale will no longer return an error. An Int64 will be returned instead.
|
829 |
|
830 |
4. TIBTransaction now has events for Before and After Transaction End and a new function
|
831 |
"GetEndAction" allowing the EndAction to be accessed by these event handlers.
|
832 |
|
833 |
5. TIBQuery can now handle correctly queries which contain the same keyword parameter
|
834 |
repeated multiple times.
|
835 |
|
836 |
6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
|
837 |
check used to get in the way of using Stored Procedures, and "Update or Insert"
|
838 |
statements.
|
839 |
|
840 |
7. Insert, Modify and Delete property Editors now support Query Generation from
|
841 |
Stored Procedures.
|
842 |
|
843 |
8. Three new examples illustrate the use of the new IB Controls
|
844 |
|
845 |
|
846 |
IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
|
847 |
|
848 |
1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
|
849 |
setting performance. See "readme.field+param.names in the doc folder.(Thanks to
|
850 |
Gabor Boros for reporting this problem and for testing the improvements).
|
851 |
|
852 |
2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
|
853 |
See readme.field+param.names in the doc folder.
|
854 |
|
855 |
3. IBX SQL Editors will now automatically add double quotes around column names when the database
|
856 |
dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
|
857 |
|
858 |
4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
|
859 |
|
860 |
5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
|
861 |
actions.
|
862 |
|
863 |
6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
|
864 |
thanks to Yuriy Kopnin for pointing this out).
|
865 |
|
866 |
7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
|
867 |
|
868 |
8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
|
869 |
for both fields and parameter setting.
|
870 |
|
871 |
9. Changes to the Select SQL in an IBCustomDataset descendent should now be
|
872 |
visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
|
873 |
|
874 |
10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
|
875 |
when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
|
876 |
|
877 |
11. TIBTable now has a property editor for "MasterFields"
|
878 |
|
879 |
12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
|
880 |
GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
|
881 |
|
882 |
13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
|
883 |
of settings is unrecognised. Selecting this radio button has no effect on the settings.
|
884 |
|

IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
|
891 |
|
892 |
1. In a TIBCustomDataset descendent, a generator now only sets the value when
|
893 |
it is null. This allows for alternative user defined setting of the generator
|
894 |
|
895 |
Many thanks to Julio Jiménez for this fix
|
896 |
|
897 |
2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
|
898 |
and suggests that the user may have forgotten to install it.
|
899 |
|

IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
|
901 |
|
902 |
1. Conditional compilation used to limit registration of TIntegerField to
|
903 |
Lazarus versions less than 1.1
|
904 |
|
905 |
2. When a database connection is created, character set is now by default set
|
906 |
to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
|
907 |
1250 to 1254.

|
916 |
|
917 |
1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
|
918 |
Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
|
919 |
|
920 |
2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
|
921 |
package is changed to do this (which it should do).
|
922 |
|
923 |
IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
|
924 |
|
925 |
1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
|
926 |
|
927 |
2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
|
928 |
|
929 |
3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
|
930 |
|
931 |
4. Property editors should now correctly resize.
|
932 |
|
933 |
5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
|
934 |
(restored original functionality)
|
935 |
|
936 |
6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
|
937 |
library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
|
