1. IBExtract: Identity columns - add additional check for null column for generator name. |
| 4 |
> |
|
| 5 |
> |
2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses. |
| 6 |
> |
The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further |
| 7 |
> |
information). However, this is also a very useful mechanism for returning updated computed by |
| 8 |
> |
column values. Values returned as a result of executing an Insert or Update statement |
| 9 |
> |
replace existing values in the current row for each corresponding column. |
| 10 |
> |
|
| 11 |
> |
Previously, if a dataset's select query included read only (computed by) fields then |
| 12 |
> |
an automatic row refresh was performed after an insert or update query had been processed, |
| 13 |
> |
irrespective of the setting of the "ForcedUpdates" property. This has changed such |
| 14 |
> |
that an automatic refresh is no longer performed if an insert or update query contains |
| 15 |
> |
a returning clause that updates one or more fields on the current row. A full row |
| 16 |
> |
refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any |
| 17 |
> |
field values and the select query contains read only fields. Use of Insert/update |
| 18 |
> |
returning should be significantly more efficient than executing a refresh query. |
| 19 |
> |
|
| 20 |
> |
This behaviour change is intended to be backwards compatible and there should be no need to change |
| 21 |
> |
existing programs, other than to improve performance by using the new capability. |
| 22 |
> |
|
| 23 |
> |
3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as |
| 24 |
> |
they are called when the dataset row is being deleted, there is no value in |
| 25 |
> |
updating the current record from the query result. Instead, a new event handler |
| 26 |
> |
"OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and |
| 27 |
> |
an OnDeleteReturning event handler is provided then it is called with the IResults returned |
| 28 |
> |
by the query. The event handler can then interrogate the query results and |
| 29 |
> |
perform whatever action is necessary. For example to confirm, to the user, |
| 30 |
> |
the deletion of a row with the returned values. |
| 31 |
> |
|
| 32 |
> |
4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for |
| 33 |
> |
any Computed By or Identity Columns. The IBTables example has been updated to |
| 34 |
> |
illustrate the computation of the employee Full Name on update. |
| 35 |
> |
|
| 36 |
> |
5. TIBTable: The GeneratorField property is now published. |
| 37 |
> |
|
| 38 |
> |
6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List. |
| 39 |
> |
When InsertSQL is generated, the Identity columns are not included in the list of values to |
| 40 |
> |
be inserted. A RETURNING clause is added to the insert statement to return the value of |
| 41 |
> |
each Identity column after the insert is executed. |
| 42 |
> |
|
| 43 |
> |
7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause. |
| 44 |
> |
Similarly Insert Property Editor now generates Insert SQL with Computed By fields in |
| 45 |
> |
Insert..Returning clause. |
| 46 |
> |
|
| 47 |
> |
8. TIBGenerator: small performance improvement by not preparing query each time |
| 48 |
> |
a new value is generated. |
| 49 |
> |
|
| 50 |
> |
9. TIBSQL: Free resources when transaction changed - ensures new transaction is used. |
| 51 |
> |
|
| 52 |
> |
10. Property editors will now sync table name to a System Table when "Include System |
| 53 |
> |
Tables" is selected and the query is for a System Table. |
| 54 |
> |
|
| 55 |
> |
11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field |
| 56 |
> |
values are no longer converted to milliseconds from TDateTime and then back again |
| 57 |
> |
to TDateTime (the conversion to milliseconds is the default TDataset approach). |
| 58 |
> |
|
| 59 |
> |
12. Property Editors handling of Stored Procedures. |
| 60 |
> |
* Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and |
| 61 |
> |
which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select |
| 62 |
> |
query). |
| 63 |
> |
* Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2). |
| 64 |
> |
|
| 65 |
> |
13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName |
| 66 |
> |
can be used to select a package. If non-empty, the stored procedure name is |
| 67 |
> |
expected to be a stored procedure defined in the specified package and the |
| 68 |
> |
generated SQL will be as required for a stored procedure located in a package. |
| 69 |
> |
|
| 70 |
> |
14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include |
| 71 |
> |
a "Package Name" drop down box to allow selection of a Firebird 3 Package from |
| 72 |
> |
which a stored procedure can be selected. With no package name selected, non-package |
| 73 |
> |
stored procedures are listed. |
| 74 |
> |
|
| 75 |
> |
15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting |
| 76 |
> |
for password on reconnect. |
| 77 |
> |
|
| 78 |
> |
16. IBDatabase: use IAttachment for connection default character set id, code page |
| 79 |
> |
and character set name. |
| 80 |
> |
|
| 81 |
> |
17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise |
| 82 |
> |
DB info lookups" |
| 83 |
> |
|
| 84 |
> |
18. IBExtract: now supports DDL Triggers. |
| 85 |
> |
|
| 86 |
> |
19. Add a property Editor for TIBUpdate.RefreshSQL. |
| 87 |
> |
|
| 88 |
> |
20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input |
| 89 |
> |
parameters. This stops an exception being raised when the field cannot be |
| 90 |
> |
located in the record buffer. |
| 91 |
> |
|
| 92 |
> |
21. Property Editors now automatically include System Tables when opened and when the query table |
| 93 |
> |
is a System Table. |
| 94 |
> |
|
| 95 |
> |
22. FB3UserManager example added to illustrate use if IBX for managing user logins, passwords |
| 96 |
> |
and connections using IBX and with single or multiple security databases. |
| 97 |
> |
|

IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000 |
| 100 |
> |
|
| 101 |
> |
1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf |
| 102 |
> |
changes. |
| 103 |
> |
|
| 104 |
> |
2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString. |
| 105 |
> |
Bug could result in truncated multi-byte character set values. |
| 106 |
> |
|
| 107 |
> |
3. Changes consequential on moving fbintf character set utility functions from |
| 108 |
> |
IFirebirdAPI to IAttachment. |
| 109 |
> |
|
| 110 |
> |
4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true |
| 111 |
> |
|
| 112 |
> |
5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally |
| 113 |
> |
results in autocomplete ignoring prefix text. |
| 114 |
> |
|
| 115 |
> |
6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when |
| 116 |
> |
entering a new name into the text box. |
| 117 |
> |
|
| 118 |
> |
7. IBCustomDataset: ensure that TIBStringField uses the field size reported by |
| 119 |
> |
Firebird rather than recomputing it. |
| 120 |
> |
|
| 121 |
> |
8. Property Editor positioning tidy up: All IBX Property editors should now be |
| 122 |
> |
screen centre. Previously some were "poDesigned" which may be inappropriate |
| 123 |
> |
for multi monitor desktops. |
| 124 |
> |
|
| 125 |
> |
10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node. |
| 126 |
> |
|
| 127 |
> |
11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending |
| 128 |
> |
a transaction and always reset the object. |
| 129 |
> |
|
| 130 |
> |
12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows. |
| 131 |
> |
|
| 132 |
> |
13. TIBXScript: Allow for override of database filename in Create Database statements. |
| 133 |
> |
|
| 134 |
> |
14. IBLocaldb: Support initialisation of the database from an SQL script in addition |
| 135 |
> |
to a gbak format archive. |
| 136 |
> |
|
| 137 |
> |
15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised. |
| 138 |
> |
|
| 139 |
> |
16. IBLocaldb: Drop database if error creating an empty database. |
| 140 |
> |
|
| 141 |
> |
17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset |
| 142 |
> |
unless selected node not in current dataset. |
| 143 |
> |
|
| 144 |
> |
18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package) |
| 145 |
> |
to TIBCustomService, and IBlocalDB code tidy up. |
| 146 |
> |
|
| 147 |
> |
19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable |
| 148 |
> |
behaviour due to uninitialised variable. |
| 149 |
> |
|
| 150 |
> |
20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from |
| 151 |
> |
integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode. |
| 152 |
> |
|
| 153 |
> |
21. IBSQL: When Database changed ensure that all resources are freed. |
| 154 |
> |
|
| 155 |
> |
22. IBCustomDataset: When database changed ensure that queries an unprepared. |
| 156 |
> |
|
| 157 |
> |
23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include: |
| 158 |
> |
* Line Wrap on SQL Token boundaries (on user command) |
| 159 |
> |
* auto-complete table names in drop down list of table names |
| 160 |
> |
* Double click on tablename or field name adds to SQL text |
| 161 |
> |
|
| 162 |
> |
24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d). |
| 163 |
> |
|
| 164 |
> |
25. IBTreeView: Call to FindNode: param type change from "array of Variant" to |
| 165 |
> |
TVariantArray. Seems to avoid memory corruption in Windows (probably a |
| 166 |
> |
workaround for a problem in fpc 3.0.4 win64). |
| 167 |
> |
|
| 168 |
> |
26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open. |
| 169 |
> |
|
| 170 |
> |
27. IBDatabaseInfo: Remove memory leak when accessing database operation counts. |
| 171 |
> |
|
| 172 |
> |
IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000 |
| 173 |
> |
|
| 174 |
> |
1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to |
| 175 |
> |
include remote system name. |
| 176 |
> |
|
| 177 |
> |
2. TIBExtract: No longer include comment header and COMMIT statement for empty |
| 178 |
> |
tables when data included in output. |
| 179 |
> |
|
| 180 |
> |
3. Profiling: IBSQL now has conditional compilation flags to enable query performance |
| 181 |
> |
and timing information to be written to stdout. This may be used to locate |
| 182 |
> |
performance bottlenecks. |
| 183 |
> |
|
| 184 |
> |
4. SQLParser: only call "OnChanging" event handler when value is different. |
| 185 |
> |
|
| 186 |
> |
5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit |
| 187 |
> |
|
| 188 |
> |
6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures |
| 189 |
> |
that BindFields is called when the query is next activated. Avoids FieldName |
| 190 |
> |
not found error. |
| 191 |
> |
|
| 192 |
> |
7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general |
| 193 |
> |
purpose and allows the programmer to define any action they want for Update, Insert |
| 194 |
> |
or Delete. This may be complex SQL (similar to a Trigger), application specific |
| 195 |
> |
filtering of updates, or use of statements such as Grant or Revoke instead of |
| 196 |
> |
normal DML. See User Manual for more information. |
| 197 |
> |
|
| 198 |

IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000 |
| 199 |
> |
|
| 200 |
> |
1. TIBEvents: Fix uninitialised variable that could result in lost events. |
| 201 |
> |
|
| 202 |
> |
2. TIBExtract: Added support for FB3 "USAGE" privilege. |
| 203 |
> |
|
| 204 |
> |
3. TIBExtract: data formatted as Charset set "octets" is now output using |
| 205 |
> |
hexadecimal notation. |
| 206 |
> |
|
| 207 |
> |
4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements |
| 208 |
> |
using a simple XML format. |
| 209 |
> |
|
| 210 |
> |
5. TIBExtract: extract of individual Triggers and Stored Procedures can now include |
| 211 |
> |
grants to these objects. |
| 212 |
> |
|
| 213 |
> |
6. TIBExtract: Stored Procedures and Views output in dependency order to avoid |
| 214 |
> |
dependency problems restoring complex databases. |
| 215 |
> |
|
| 216 |
> |
7. TIBXScript: This component has been restructured to allow for the processing of |
| 217 |
> |
embedded XML in INSERT statements and to support interactive sources in addition |
| 218 |
> |
to non-interactive data sources such as files. |
| 219 |
> |
|
| 220 |
> |
8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported. |
| 221 |
> |
|
| 222 |
> |
9. TIBXScript: ISQL compatiable Set statements are now supported: |
| 223 |
> |
SET SQL DIALECT |
| 224 |
> |
SET TERM |
| 225 |
> |
SET AUTODDL |
| 226 |
> |
SET BAIL |
| 227 |
> |
SET ECHO |
| 228 |
> |
SET COUNT |
| 229 |
> |
SET STATS |
| 230 |
> |
SET NAMES <character set> |
| 231 |
> |
|
| 232 |
> |
10. IBVersion unit added to hold current IBX Version Number information. |
| 233 |
> |
|
| 234 |
> |
11. TIBExtract: Use character rather than byte length for VarChar procedure arguments., |
| 235 |
> |
and domain definitions. |
| 236 |
> |
|
| 237 |
> |
12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers |
| 238 |
> |
fully supported. |
| 239 |
> |
|
| 240 |
> |
13. TIBExtract: when a database dump includes data, the generator values are now also set. |
| 241 |
> |
|
| 242 |
> |
14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later. |
| 243 |

See also doc/IBX4LazarusGuide.pdf for important information on |
| 247 |
> |
upgrading to IBX2. |
| 248 |
> |
|
| 249 |
> |
1. Size property of TIBStringField is now the width in characters of the field |
| 250 |
> |
and not the byte length. This applies only to multi-byte character sets such |
| 251 |
> |
as UTF8. The original approach aligned with TStringField. However, the TStringField |
| 252 |
> |
code is not recognised as a bug and hence this change to align the behaviour. |
| 253 |
> |
The TStringField change is expected in fpc 3.2.0. |
| 254 |
> |
|
| 255 |
> |
2. A new property AutoFieldSize: boolean has been added to TIBStringField. When |
| 256 |
> |
true (default) then Size property value saved in the lfm is ignored. Size is |
| 257 |
> |
always set from the dynamic information read from the database. It is unclear |
| 258 |
> |
why anyone would want to override this and set Size to false. |
| 259 |
> |
|
| 260 |
> |
3. ibxscript: should now handle correctly a Case..End statement within a procedure |
| 261 |
> |
block. |
| 262 |
> |
|
| 263 |
> |
4. IBDatabase: new property - CreateIfNotExists. If true and database does not |
| 264 |
> |
exist when an attempt is made to connect to it (run time only) then an attempt |
| 265 |
> |
is made to create the database. |
| 266 |
> |
|
| 267 |
> |
5. IBDatabase: new event - OnCreateDatabase. This event is called after a database |
| 268 |
> |
has been successfully created as a result of a call to CreateDatabase or when |
| 269 |
> |
creating a database after it was found not to exist. |
| 270 |
> |
|
| 271 |
> |
6. DBControlGrid: a race condition could result in the wrong row image being |
| 272 |
> |
written to the cache. This has been avoided by a trip round the message |
| 273 |
> |
loop before rendering the row image. |
| 274 |
> |
|
| 275 |
> |
7. DBControlGrid: It is strongly recommended not to open the source DataSet for |
| 276 |
> |
a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is |
| 277 |
> |
known to risk corrupt rendering of row images when the control is first |
| 278 |
> |
displayed. If necessary use "Application.QueueAsyncCall" to delay opening |
| 279 |
> |
of the dataset (see DBControlGrid examples) until the Form's Window has been created. |
| 280 |
> |
|
| 281 |
> |
8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with |
| 282 |
> |
a TDateEdit control located on an editor panel. |
| 283 |
> |
|
| 284 |
> |
9. TIBExtract: brought up-to-date plus many bug fixes. |
| 285 |
> |
|
| 286 |
> |
10. DBControlGrid: Removed memory leak when updating rows. |
| 287 |
> |
|
| 288 |
> |
11. TIBCMLocalDBSupport: fixed invalid free on upgrade. |
| 289 |
> |

|
| 292 |
> |
1. IBCustomDataset: When calling SetCodePage, no longer request transliteration |
| 293 |
> |
when target codepage is CP_NONE. This is a workaround for |
| 294 |
> |
http://bugs.freepascal.org/view.php?id=30622. |
| 295 |
> |
|
| 296 |
> |
2. DBLog option removed from TIBStatisticalService - not supported by server |
| 297 |
> |
since Firebird 1.5. |
| 298 |
> |
|
| 299 |
> |
3. ibxscript: An error is no longer generated for "on commit preserve rows" or |
| 300 |
> |
similar. |
| 301 |
> |
|
| 302 |
> |
4. IBCodePage: updated mapping between codepages and character id. |
| 303 |
> |
|
| 304 |
> |
5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in |
| 305 |
> |
Firebird. Character sets with a char width of two are not UTF16. |
| 306 |
> |
|
| 307 |
> |
6. Strings received from the database are now always transliterated into UTF8 |
| 308 |
> |
regardless of the database character set or connection character set. This |
| 309 |
> |
is for compatibility with the LCL. |
| 310 |

1. IBBlob: Defer reading of blob until read method called. This avoids having to |
| 314 |
> |
read in an entire blob just to get the size of the blob. General performance |
| 315 |
> |
improvement when opening datasets containing blobs. |
| 316 |
> |
|
| 317 |
> |
2. Clearing a Blob now sets the corresponding field's modified flag. |
| 318 |
> |
|
| 319 |
> |
3. IBLookupCombo: When not performing auto-complete, original query sort order |
| 320 |
> |
is now used. |

IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100 |
| 334 |
> |
|
| 335 |
> |
1. No character set specified for connection: when a text blob is retrieved, the |
| 336 |
> |
character set is determined by looking up the native character set using then |
| 337 |
> |
Firebird API. Otherwise a text mode blob is assumed to have the same character |
| 338 |
> |
set as the connection. |
| 339 |
> |
|
| 340 |
> |
2. TIBGUIInterface: this is an internal interface. Minor type changes to allow |
| 341 |
> |
for Login Dialog returing a change to the database path. |
| 342 |
> |
|
| 343 |
> |
3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name |
| 344 |
> |
to be changed from that given in the TIBDatabase/TIBServer component and for the |
| 345 |
> |
entered value to be saved on a project specific basis (design time only). |
| 346 |
> |
|
| 347 |
> |
4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the |
| 348 |
> |
column fieldname. If they are the same then it is acts as a look up for the KeyValue |
| 349 |
> |
Otherwise, it sets the column text to the selected ListField Value. |
| 350 |
> |
|
| 351 |
> |
5. IBDynamicGrid: Only visible columns are now taken into account When recalculating |
| 352 |
> |
column width. |
| 353 |
> |
|
| 354 |
> |
6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given |
| 355 |
> |
and a case insensitive search is requested. |
| 356 |
> |
|
| 357 |
> |
7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls |
| 358 |
> |
or column ListSource. |
| 359 |
> |
|
| 360 |
> |
8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an |
| 361 |
> |
unprepare) when closing and the text has not changed. |
| 362 |
> |
|
| 363 |
> |
9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer. |
| 364 |
> |
Less likely to cause a cursor re-use error on Windows. |
| 365 |
> |
|
| 366 |
> |
10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin. |
| 367 |
> |
Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0. |
| 368 |
> |
|
| 369 |
> |
11. TIBTreeView: Guard against nil destination on record changed |
| 370 |
> |
|
| 371 |
> |
12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a |
| 372 |
> |
string type with the code page set to reflect the returned field encoding after |
| 373 |
> |
Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for |
| 374 |
> |
earlier versions. |
| 375 |
> |
|
| 376 |
> |
13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString |
| 377 |
> |
will now result in transliteration to the code page specified for the Firebird driver |
| 378 |
> |
if the assigned string has a different code page. FPC 3.0.0 onwards only. |
| 379 |
> |
|
| 380 |
> |
14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter |
| 381 |
> |
is ignored and the lc_ctype value, when the database is opened, is set to align with |
| 382 |
> |
the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure |
| 383 |
> |
platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC |
| 384 |
> |
3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when |
| 385 |
> |
the GETACP is used to determine the Windows code page. |
| 386 |
> |
|
| 387 |
> |
15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set |
| 388 |
> |
name used as the lc_ctype when the database was opened. Only valid while the |
| 389 |
> |
Database is connected. |
| 390 |
> |
|
| 391 |
> |
16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage |
| 392 |
> |
id that corresponds to the DefaultCharSetName. |

1. Unix: If Firebird Embedded Server shared object is loaded and a local database |
| 397 |
> |
path is given and database attach fails due to access permission issues on the |
| 398 |
> |
temp directory or security database, then the attach is retried with "localhost:" |
| 399 |
> |
prefixing the databasename. This should avoid problems when the database has to |
| 400 |
> |
be accessed by a local (e.g. classic) server and libfbembed is used. |
| 401 |
> |
|
| 402 |
> |
2. Windows: revised search order for Firebird DLL: |
| 403 |
> |
i. The Firebird Embedded Server in the application Directory. |
| 404 |
> |
ii. If the FIREBIRD environment variable is set then the directory this |
| 405 |
> |
points to is searched for the FB Client DLL and then then underlying |
| 406 |
> |
"bin" directory. |
| 407 |
> |
iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances |
| 408 |
> |
is used to locate the Firebird installation directory and the underlying |
| 409 |
> |
"bin" directory is searched for the FB Client DLL. |
| 410 |
> |
iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x |
| 411 |
> |
are searched for the FB Client DLL. |
| 412 |
> |
v. The PATH Environment variable is used to search for the FB Client DLL. |
| 413 |
> |
vi. Finally the PATH Environment variable is used to search for IBASE.DLL. |
| 414 |
> |
|
| 415 |
> |
3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine. |
| 416 |
> |
See doc/readme.scriptengine and example applications. |
| 417 |
> |
|
| 418 |
> |
4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to |
| 419 |
> |
simplify the use of the embedded firebird server on both Linux and Windows platforms. |
| 420 |
> |
See dpc/readme.localdatabase and example applications. |
| 421 |
> |
|
| 422 |
> |
5. IBDynamicGrid: Reordering on column header click should now also work for |
| 423 |
> |
dynamic columns. |
| 424 |
> |
|
| 425 |
> |
6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition |
| 426 |
> |
between incrementing/decrementing the lock count and signalling the event. |
| 427 |
> |
|
| 428 |

IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000 |
| 429 |
> |
|
| 430 |
> |
1.3.2 was never formally released and only made available as beta copies. |
| 431 |
> |
|
| 432 |
> |
1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo |
| 433 |
> |
|
| 434 |
> |
2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column |
| 435 |
> |
|
| 436 |
> |
3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early |
| 437 |
> |
|
| 438 |
> |
4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset |
| 439 |
> |
i.e. when it is a calculated field |
| 440 |
> |
|
| 441 |
> |
5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid. |
| 442 |
> |
This problem was due to a race condition between recalculating row heights and |
| 443 |
> |
determining which row was selected by the mouse click. The row height calculation |
| 444 |
> |
is now deferred by an extra trip round the message loop allowing the row to |
| 445 |
> |
be always calculated on the current grid layout rather than risking it being |
| 446 |
> |
calculated on the grid layout after the expanded row has been shrunk. |
| 447 |
> |
|
| 448 |
> |
6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on |
| 449 |
> |
Windows. |
| 450 |
> |
|
| 451 |
> |
7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer; |
| 452 |
> |
These properties allow the (Firebird) character set name for the field and the max number of bytes per character |
| 453 |
> |
to be determined at runtime. See doc/readme.charactersets.html. |
| 454 |
> |
|
| 455 |
> |
8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from |
| 456 |
> |
TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html. |
| 457 |
> |
|
| 458 |
> |
9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from |
| 459 |
> |
TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of |
| 460 |
> |
1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html. |
| 461 |
> |
|
| 462 |
> |
Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated |
| 463 |
> |
from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero |
| 464 |
> |
implies no truncation. |
| 465 |
> |
|
| 466 |
> |
10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active. |
| 467 |
> |
|
| 468 |
> |
11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state |
| 469 |
> |
(avoids "Not in Edit Mode" error). |
| 470 |
> |
|
| 471 |
> |
12. IBDynamicGrid: Correctly resize grid when one column width plus indicator. |
| 472 |
> |
|
| 473 |
> |
13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling |
| 474 |
> |
DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control. |
| 475 |
> |
|
| 476 |
> |
14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent. |
| 477 |
> |
|
| 478 |
> |
15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls |
| 479 |
> |
|
| 480 |
> |
16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked. |
| 481 |
> |
|
| 482 |
> |
17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened. |
| 483 |

| 486 |
> |
1. OnCloseUp Event Handler added to TDBLookupProperties |
| 487 |
> |
|
| 488 |
> |
2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids |
| 489 |
> |
problem with row size when exception is called. |
| 490 |
> |
|
| 491 |
> |
3. IBLookupComboEditBox: Force pending autocomplete on combobox exit. |
| 492 |
> |
|
| 493 |
> |
4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if |
| 494 |
> |
in a TCustomComboBox and ignores return key if in a TCustomMemo |
| 495 |
> |
|
| 496 |
> |
5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text |
| 497 |
> |
keyed in i.e. when autocomplete not performed |
| 498 |
> |
|
| 499 |
> |
6. Cleanup of "Uses" clauses and add console mode support. IBX should now support |
| 500 |
> |
console mode applications with all LCL required functions (builtin dialogs and |
| 501 |
> |
cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is |
| 502 |
> |
not included in your project, IBX should compile and link with a console mode program. |
| 503 |
> |
See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a |
| 504 |
> |
console mode application or the IDE will automatically assume that your |
| 505 |
> |
application is GUI based. Instead, you should include the ibexpressconsolemode package. |
| 506 |
> |
|
| 507 |
> |
IMPORTANT NOTE: IBDialogs must be included in GUI applications in order |
| 508 |
> |
to use the built in dialogs and cursor management. IBDialogs is |
| 509 |
> |
included by default if "ibexpress" is in your project source's "uses" clause. |
| 510 |
> |
This should be the case for all projects created through the IDE. This is why |
| 511 |
> |
you do not want to add the ibexpress package to console mode applications. The |
| 512 |
> |
ibexpressconsolemode package has been created to allow console mode programs |
| 513 |
> |
to avoid adding LCL dependencies when using IBX, while still having the |
| 514 |
> |
unit search paths set up correctly. |
| 515 |
> |
|
| 516 |
> |
Existing users should check to ensure that the "ibexpress" unit is included in |
| 517 |
> |
each project's source file (*.lpr). |
| 518 |
> |
|
| 519 |
> |
You may find that in order for the IDE to recognise that ibexpressconsolemode |
| 520 |
> |
exists, you have to first open the package in the IDE and then close it. This |
| 521 |
> |
adds it to the most recently accessed packages list. To make it permanently |
| 522 |
> |
available, add the package name to lazarus' staticpackages.inc file. |
| 523 |
> |
|
| 524 |
> |
Thanks to Julio Jiménez for suggesting support of console mode. |
| 525 |
> |
|
| 526 |
> |
7. SQL Parser can now accept quoted strings that include new lines |
| 527 |
> |
|
| 528 |
> |
8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end |
| 529 |
> |
of text on start of edit. This is particularly useful when tabbing to a |
| 530 |
> |
column and then inserting text. |
| 531 |
> |
|
| 532 |
> |
9. New Examples provided for IB Services and ISQLMonitor. |
| 533 |
> |
|
| 534 |
> |
10. Fix error when writing to blob streams that recorded only the last buffer |
| 535 |
> |
write in the blob stream. In most cases, this did not cause a problem as the |
| 536 |
> |
IB Blob Stream is written in a single write. However, with the TDBImage, write |
| 537 |
> |
of a graphic type prefix was lost which caused a problem when the image could |
| 538 |
> |
not be automatically recognised. |
| 539 |
> |
|
| 540 |
> |
11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor |
| 541 |
> |
already open" errors due to random numbers used for the cursor name being identical. |
| 542 |
> |
|
| 543 |
> |
12. IBTable: corrected error that could result in an "Index out of bounds" error |
| 544 |
> |
when opening the table and the Primary Key is the last or only column in the |
| 545 |
> |
table. Thanks to Rick Hoover for the fix. |
| 546 |
> |
|
| 547 |
> |
13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead |
| 548 |
> |
of "UTF-8", and update list of available database character sets. Existing |
| 549 |
> |
users should check the current lc_ctype setting in their applications. |

1. Firebird Services: avoid List Index error when opening a service with an |
| 554 |
> |
empty Params property. |
| 555 |
> |
|
| 556 |
> |
2. IBControls: Fix problem with new link mechanism introduced in 1.2.3. |
| 557 |
> |
Link now set up in Loaded method - avoids occasional failure to apply |
| 558 |
> |
SQL markup on initial open. |
| 559 |
> |
|
| 560 |
> |
3. "Employees" example performance improvements when scrolling. |
| 561 |
> |
|
| 562 |
> |
4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a |
| 563 |
> |
TFrame. Force recaching of selected frame to avoid GTK race (results in a |
| 564 |
> |
random image cached). |
| 565 |
> |
|
| 566 |
> |
5. DBControlGrid: Should now react to changes in panel height at run time. |
| 567 |
> |
|
| 568 |
> |
6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid |
| 569 |
> |
even when further rows exist. |
| 570 |
> |
|
| 571 |
> |
7. DBControlGrid: DefaultRowHeight is no longer a published property as it should |
| 572 |
> |
always be derived from panel height and setting this property can cause confusion. |
| 573 |
> |
Note for existing projects: to avoid a missing property error at run time, |
| 574 |
> |
each form using the DBControlGrid must be opened, updated and saved in the IDE |
| 575 |
> |
in order to remove the property value from the lfm. |

1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always |
| 581 |
> |
call Prepare before setting parameter values. |
| 582 |
> |
|
| 583 |
> |
2. Error message on ParamByName (all cases) not found now includes name of missing parameter. |
| 584 |
> |
|
| 585 |
> |
3. Code tidyup and more robust handling of dsql information result vector. |
| 586 |
> |
|
| 587 |
> |
4. Support for centralised handling of transaction status changes. TIBTransaction |
| 588 |
> |
has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost" |
| 589 |
> |
and "AfterExecQuery". The first three are called after the same event is called |
| 590 |
> |
for an IBCustomDataSet descendent using the Transaction. The fourth is called |
| 591 |
> |
after a call to TIBSQL.ExecQuery, again using this transaction. These new events |
| 592 |
> |
enable monitoring of transaction status changes for a given transaction to be |
| 593 |
> |
handled in a single place. For example, when a change to the dataset occurs |
| 594 |
> |
an indicator can be set that shows the user that in order to save changes, |
| 595 |
> |
the transaction should be committed. Rather than doing this per dataset, this |
| 596 |
> |
can now be done per transaction. |
| 597 |
> |
|
| 598 |
> |
5. TDataSet.CheckBrowseMode automatically posts changes to the current row when |
| 599 |
> |
the dataset is scrolled. However, any changes to the current row are, by default, |
| 600 |
> |
discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now |
| 601 |
> |
have a new property "DataSetCloseAction" that adds automatic posting of changes |
| 602 |
> |
on dataset close. If this property is set to dcDiscardChanges (default) then the |
| 603 |
> |
behaviour is unchanged from previous versions. if the value is set to dcSaveChanges |
| 604 |
> |
then IBX will attempt to post any unsaved changes before the dataset is closed |
| 605 |
> |
(and after the BeforeClose event handler is called). The exception is when the |
| 606 |
> |
dataset is being closed as a result of a transaction rollback. In this case, |
| 607 |
> |
no action is taken and any unsaved changes are discarded. This avoids both |
| 608 |
> |
unnecessary overhead and the risk that a validation error may occur in the Post |
| 609 |
> |
raising an exception and thereby preventing a rollback. |
| 610 |
> |
|
| 611 |
> |
6. String Field sizes and Display Widths should now be correct for multi-byte character sets. |
| 612 |
> |
In earlier versions, the Display Width was set to the maximum byte width rather than the character |
| 613 |
> |
width. Display Widths are now corrected by dividing by the max byte width per character. |
| 614 |
> |
For UTF8 character sets, the byte width is four and hence the Display Width will be |
| 615 |
> |
the byte width divided by 4. The byte width of each character set is determined |
| 616 |
> |
dynamically when the database connection is estabished from the RDB$CHARACTER_SETS |
| 617 |
> |
system table. (see also http://bugs.freepascal.org/view.php?id=27766). |
| 618 |
> |
|
| 619 |
> |
7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string. |
| 620 |

8. IBLookupComboEditBox: List should now always be restored to full list when the |
| 622 |
> |
control loses focus. Default Key press default interval reduced to 200ms. |
| 623 |
> |
|
| 624 |
> |
9. DBControlGrid: Ensure that selection is changed to newly appended row, even |
| 625 |
> |
when dataset rows are less than visible rows. |
| 626 |
> |
|
| 627 |
> |
10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource |
| 628 |
> |
does not exist or DataSet is empty. More responsive on dataset open. New event |
| 629 |
> |
OnRestorePosition. Column sort disabled if no header row. |
| 630 |
> |
|
| 631 |
> |
11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset |
| 632 |
> |
while dataset state is dsInsert. Avoids posting errors. |
| 633 |
> |
|
| 634 |
> |
12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to |
| 635 |
> |
avoid conflict with DisableControls/EnableControls with Master/Detail linked tables. |
| 636 |
> |
|
| 637 |
> |
13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes. |
| 638 |
> |
|
| 639 |
> |
14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced |
| 640 |
> |
to solve a specific problem. That is when the dataset cursor is moved (e.g. by |
| 641 |
> |
a grid mouse click and the current row is being edited or inserted. In this case, TDataset |
| 642 |
> |
always "posts" the current record regardless or whether or not it may be more appropriate |
| 643 |
> |
to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the |
| 644 |
> |
"MoveBy" function is implemented by TDataSet. The OnValidatePost event is called |
| 645 |
> |
as the first action of the "Post" method and allows the handler to convert the Post |
| 646 |
> |
into a Cancel if that is the appropriate action on moving to a different row. This is |
| 647 |
> |
achieved by returning with "CancelPost" argument set to true. Note that an exception could be |
| 648 |
> |
raised here, but it may still be more appropriate to validate a post and signal |
| 649 |
> |
a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml) |
| 650 |

15. On Unix derived systems, the Firebird library name can now be given as a colon |
| 652 |
> |
separated list. Each library name on the list is tried in turn, in left to right |
| 653 |
> |
order with the first found being used as the firebird library. By default, on Linux, |
| 654 |
> |
the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be |
| 655 |
> |
overidden by the FBLIB environment variable or the OnGetLibraryName function. |
| 656 |
> |
|
| 657 |
> |
Note: when using the libfbembed.so, if you prefix the database name with "localhost:" |
| 658 |
> |
then it will still attempt to access the database via the Firebird Server and will |
| 659 |
> |
require a username and password. If only the pathname is given, then the username |
| 660 |
> |
and password should be omitted and the unix file permissions are used to grant |
| 661 |
> |
access. |

1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike |
| 666 |
> |
rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid |
| 667 |
> |
that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row |
| 668 |
> |
corresponds to a row of the linked DataSource. Any data aware control on the |
| 669 |
> |
replicated (e.g.) TPanel will then appear to have the appropriate value for the row. |
| 670 |
> |
|
| 671 |

2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase. |
| 672 |
> |
When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change |
| 673 |
> |
takes place during database access. This may be useful when there are performance issues with |
| 674 |
> |
the change of cursor. Setting the property to false suppresses the change of cursor. |
| 675 |
> |
|
| 676 |
> |
3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery |
| 677 |
> |
and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to |
| 678 |
> |
Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of |
| 679 |
> |
making all changes permanent immediately rather than when the transaction is explicitly |
| 680 |
> |
committed. |
| 681 |
> |
|
| 682 |
> |
4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still |
| 683 |
> |
using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature. |

1. An internal select SQL Parser is now available for TIBCustomDataset descendents. |
| 692 |
|
This is typically used during an "OnBeforeOpen" event handler to manipulate the |
| 704 |
|
TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete" |
| 705 |
|
of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation |
| 706 |
|
to revise the available list and restrict it to items that are prefixed by the |
| 707 |
< |
typed text (either case sensitive or case insenstive). Autoinsert allows a |
| 707 |
> |
typed text (either case sensitive or case insensitive). Autoinsert allows a |
| 708 |
|
newly typed entry to be added to the list dataset and included in the available |
| 709 |
|
list items. |
