|
| 3 |
> |
IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove |
| 4 |
> |
all previous copies of the IBX source code tree before installing this release. |
| 5 |
> |
|
| 6 |
> |
The IBX packages used by most users have not changed, with one exception. The |
| 7 |
> |
IBServices unit has been moved to the package iblegacyServices.lpk. To continue |
| 8 |
> |
to use the IBServices unit in your applications, please add the iblegacyServices |
| 9 |
> |
to the list of dependencies. To do this, open the Project Inspector and select |
| 10 |
> |
Add->New Requirement and select "ibLegacyServices" from the list of available |
| 11 |
> |
packages. |
| 12 |
> |
|
| 13 |
> |
1. New unit IBXServices. The IBXServices unit is a re-architectured update of |
| 14 |
> |
the IBServices unit providing what is intended to be a clearer and easier to |
| 15 |
> |
use set of IB Services components. See Chapter 10 of the IBX User Guide for |
| 16 |
> |
more information and the guide to "Firebird Service Management Using IBX". |
| 17 |
> |
As indicated above, the legacy services components are still available and |
| 18 |
> |
provided in a separate package. There is no need to update working applications |
| 19 |
> |
using the older versions except for an additional package dependency. |
| 20 |
> |
|
| 21 |
> |
2. The IBX packages and source code tree have been re-organised in an attempt to |
| 22 |
> |
finally get rid of the "duplicate ppu" warnings. This re-organisation should |
| 23 |
> |
not affect existing users. Section 2.3 of the IBX User Guide describes the |
| 24 |
> |
new set of IBX packages. |
| 25 |
> |
|
| 26 |
> |
3. The ibx/examples/DBAdmin and the ibx/examples/services example have been |
| 27 |
> |
updated to use the new Services API components. |
| 28 |
> |
|
| 29 |
> |
4. The iblocal package has been updated to use the new Services API components. |
| 30 |
> |
|
| 31 |
> |
5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of |
| 32 |
> |
TIBXSecurityService. It had been wrongly classified in the previous version |
| 33 |
> |
as a per database configuration item. It is global to a server and hence |
| 34 |
> |
correctly positioned as part of the Security Package. In the DBAdmin example, |
| 35 |
> |
the setting has moved to the mappings page. |
| 36 |
> |
|
| 37 |
> |
6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements |
| 38 |
> |
are ignored. |
| 39 |
> |
|
| 40 |
> |
7. TIBDatabase: DropDatabase now ensures that all transactions have been properly |
| 41 |
> |
closed before the database is dropped. Before and After Disconnect event handlers |
| 42 |
> |
are also fired. |
| 43 |
> |
|
| 44 |
> |
8. TIBTransaction: OnStartTransaction event now fires every time the transaction |
| 45 |
> |
is started and not just the first time. |
| 46 |
> |
|
| 47 |
> |
9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform |
| 48 |
> |
depenendency with comp type. |
| 49 |
> |
|
| 50 |
> |
10. IBDataOutput: select query data output is now sent to stdout instead of stderr. |
| 51 |
> |
|
| 52 |
> |
11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName |
| 53 |
> |
then this is recognised and not ignored. |
| 54 |
> |
|
| 55 |
> |
12. TIBDataSet, TIBQuery, TIBTable: additions: |
| 56 |
> |
function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean; |
| 57 |
> |
function GetPerfStatistics(var stats: TPerfCounters): boolean; |
| 58 |
> |
property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics; |
| 59 |
> |
|
| 60 |
> |
GetRowsAffected returns the affected row counts from the last insert/update/delete |
| 61 |
> |
if EnableStatistics = true then GetPerfStatistics returns the current stats |
| 62 |
> |
counters for the select query. Note: stats accumulate after each fetch from |
| 63 |
> |
the database. To get total query cost after open, call the "Last" method |
| 64 |
> |
and then GetPerfStatistics. |
| 65 |
> |
|
| 66 |
> |
See ibx/examples/consolemode for an example of the use of GetPerfStatistics |
| 67 |
> |
|
| 68 |
> |
13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated |
| 69 |
> |
in parenthesises. |
| 70 |
> |
|
| 71 |
> |
14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3 |
| 72 |
> |
SQL identifiers are always delimited by double quotes. If false, then they are |
| 73 |
> |
only delimited if the identifier is a reserved word, contains lower case or special |
| 74 |
> |
characters. Set this property to true to retain previous behaviour. |
| 75 |
> |
|
| 76 |
> |
15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names |
| 77 |
> |
are now inserted in double quotes if not Reserved Words or valid SQL Identifiers. |
| 78 |
> |
|
| 79 |
> |
16. TIBDataSet, TIBQuery, TIBTable: addition: |
| 80 |
> |
property MasterDetailDelay: integer {defaults to zero} |
| 81 |
> |
|
| 82 |
> |
When non-zero and the dataset is a detail table referencing a master table |
| 83 |
> |
through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery) |
| 84 |
> |
then a synchronisation delay is added (in milliseconds) between the master |
| 85 |
> |
row changing and the detail dataset being re-opened. If the master dataset |
| 86 |
> |
is scrolled before the delay expires then the delay is reset. This can be used |
| 87 |
> |
to avoid performance overheads when scrolling through a large master dataset. |
| 88 |
> |
|
| 89 |
> |
Note: uses fptimer and hence requires a thread manager. Under Linux the |
| 90 |
> |
chreads unit must be included in your project. TTimer is not used in order |
| 91 |
> |
to avoid an LCL dependency. Requires FPC 3.0.2 or later. |
| 92 |
> |
|
| 93 |
> |
17. TIBExtract: User role grants now excluded when etGrantsToUser not specified |
| 94 |
> |
with Extract Option eoDatabase. |
| 95 |
> |
|
| 96 |
> |
18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428 |
| 97 |
> |
When a deLayoutChanged event is reported on the ListSource dataset, the |
| 98 |
> |
combobox text is updated. This allows a listsource (detail) to be in a Master/Detail |
| 99 |
> |
relationship with the control's datasource (master). |
| 100 |
> |
|
| 101 |
> |
19. TIBExtract: Full BigInt value range now supported for Generators/Sequences. |
| 102 |
> |
|
| 103 |
> |
20. Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their |
| 104 |
> |
stubs. Pedantic fix really, as procedures output in dependency order anyway. |
| 105 |
> |
|
| 106 |
> |
21. TIBExtact: Package Headers and Package Bodies are now included in the extracted |
| 107 |
> |
DDL (Firebird 3 and later only). |
| 108 |
> |
|
| 109 |
> |
22. TIBLookupComboBox Autocomplete Fixes: |
| 110 |
> |
i. Only appended text is now selected after autocomplete. |
| 111 |
> |
ii. Uppercase keys no longer ignored for autocomplete. |
| 112 |
> |
iii. Retain Prefix case is now honoured correctly. |
| 113 |
> |
iv. When a DataSource is assigned, typing after autocomplete now extends prefix |
| 114 |
> |
before autocomplete performed. i.e. behaviour now the same as when |
| 115 |
> |
no DataSource assigned. |
| 116 |
> |
|
| 117 |
> |
23. Single Line Comments starting with '--' are now ignored when occurring |
| 118 |
> |
between SQL statements. |
| 119 |
> |
|
| 120 |
> |
24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then |
| 121 |
> |
ObjectNames are converted to upper case before matching against metadata object |
| 122 |
> |
names, unless the objectname is delimited by double quotes, in which case, the |
| 123 |
> |
double quotes are removed and the remaining string is used (unmodified) to match |
| 124 |
> |
against the metadata object name. |
| 125 |
> |
|
| 126 |
> |
If true then the ObjectName is used as is without modification and matched |
| 127 |
> |
against the metadata object name. No attempt is made to remove double quotes. |
| 128 |
> |

IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000 |
| 130 |
> |
|
| 131 |
> |
NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO |
| 132 |
> |
AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS |
| 133 |
> |
RELEASE. |
| 134 |
> |
|
| 135 |
> |
NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE. |
| 136 |
> |
|
| 137 |
> |
1. IBExtract: Identity columns - add additional check for null column for generator name. |
| 138 |
> |
|
| 139 |
> |
2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses. |
| 140 |
> |
The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further |
| 141 |
> |
information). However, this is also a very useful mechanism for returning updated computed by |
| 142 |
> |
column values. Values returned as a result of executing an Insert or Update statement |
| 143 |
> |
replace existing values in the current row for each corresponding column. |
| 144 |
> |
|
| 145 |
> |
Previously, if a dataset's select query included read only (computed by) fields then |
| 146 |
> |
an automatic row refresh was performed after an insert or update query had been processed, |
| 147 |
> |
irrespective of the setting of the "ForcedUpdates" property. This has changed such |
| 148 |
> |
that an automatic refresh is no longer performed if an insert or update query contains |
| 149 |
> |
a returning clause that updates one or more fields on the current row. A full row |
| 150 |
> |
refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any |
| 151 |
> |
field values and the select query contains read only fields. Use of Insert/update |
| 152 |
> |
returning should be significantly more efficient than executing a refresh query. |
| 153 |
> |
|
| 154 |
> |
This behaviour change is intended to be backwards compatible and there should be no need to change |
| 155 |
> |
existing programs, other than to improve performance by using the new capability. |
| 156 |
> |
|
| 157 |
> |
3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as |
| 158 |
> |
they are called when the dataset row is being deleted, there is no value in |
| 159 |
> |
updating the current record from the query result. Instead, a new event handler |
| 160 |
> |
"OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and |
| 161 |
> |
an OnDeleteReturning event handler is provided then it is called with the IResults returned |
| 162 |
> |
by the query. The event handler can then interrogate the query results and |
| 163 |
> |
perform whatever action is necessary. For example to confirm, to the user, |
| 164 |
> |
the deletion of a row with the returned values. |
| 165 |
> |
|
| 166 |
> |
4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for |
| 167 |
> |
any Computed By or Identity Columns. The IBTables example has been updated to |
| 168 |
> |
illustrate the computation of the employee Full Name on update. |
| 169 |
> |
|
| 170 |
> |
5. TIBTable: The GeneratorField property is now published. |
| 171 |
> |
|
| 172 |
> |
6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List. |
| 173 |
> |
When InsertSQL is generated, the Identity columns are not included in the list of values to |
| 174 |
> |
be inserted. A RETURNING clause is added to the insert statement to return the value of |
| 175 |
> |
each Identity column after the insert is executed. |
| 176 |
> |
|
| 177 |
> |
7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause. |
| 178 |
> |
Similarly Insert Property Editor now generates Insert SQL with Computed By fields in |
| 179 |
> |
Insert..Returning clause. |
| 180 |
> |
|
| 181 |
> |
8. TIBGenerator: small performance improvement by not preparing query each time |
| 182 |
> |
a new value is generated. |
| 183 |
> |
|
| 184 |
> |
9. TIBSQL: Free resources when transaction changed - ensures new transaction is used. |
| 185 |
> |
|
| 186 |
> |
10. Property editors will now sync table name to a System Table when "Include System |
| 187 |
> |
Tables" is selected and the query is for a System Table. |
| 188 |
> |
|
| 189 |
> |
11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field |
| 190 |
> |
values are no longer converted to milliseconds from TDateTime and then back again |
| 191 |
> |
to TDateTime (the conversion to milliseconds is the default TDataset approach). |
| 192 |
> |
|
| 193 |
> |
12. Property Editors handling of Stored Procedures. |
| 194 |
> |
* Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and |
| 195 |
> |
which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select |
| 196 |
> |
query). |
| 197 |
> |
* Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2). |
| 198 |
> |
|
| 199 |
> |
13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName |
| 200 |
> |
can be used to select a package. If non-empty, the stored procedure name is |
| 201 |
> |
expected to be a stored procedure defined in the specified package and the |
| 202 |
> |
generated SQL will be as required for a stored procedure located in a package. |
| 203 |
> |
|
| 204 |
> |
14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include |
| 205 |
> |
a "Package Name" drop down box to allow selection of a Firebird 3 Package from |
| 206 |
> |
which a stored procedure can be selected. With no package name selected, non-package |
| 207 |
> |
stored procedures are listed. |
| 208 |
> |
|
| 209 |
> |
15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting |
| 210 |
> |
for password on reconnect. |
| 211 |
> |
|
| 212 |
> |
16. TIBDatabase: use IAttachment for connection default character set id, code page |
| 213 |
> |
and character set name. |
| 214 |
> |
|
| 215 |
> |
17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise |
| 216 |
> |
DB info lookups" |
| 217 |
> |
|
| 218 |
> |
18. IBExtract: now supports DDL Triggers and Grants to DDL objects. |
| 219 |
> |
|
| 220 |
> |
19. Add a property Editor for TIBUpdate.RefreshSQL. |
| 221 |
> |
|
| 222 |
> |
20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input |
| 223 |
> |
parameters. This stops an exception being raised when the field cannot be |
| 224 |
> |
located in the record buffer. |
| 225 |
> |
|
| 226 |
> |
21. Property Editors now automatically include System Tables when opened and when the query table |
| 227 |
> |
is a System Table. |
| 228 |
> |
|
| 229 |
> |
22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception. |
| 230 |
> |
This avoids errors due to a stale SQRB or SRB being used for the next query. |
| 231 |
> |
|
| 232 |
> |
23. IBServices: Service attach parameters now include "expected_db". This is used to |
| 233 |
> |
add the SPB item isc_spb_expected_db. This names a database using |
| 234 |
> |
an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a |
| 235 |
> |
database. examples/services re-written to illustrate use of "expected_db". |
| 236 |
> |
|
| 237 |
> |
24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout. |
| 238 |
> |
This avoids truncated backups when the server returns a timeout (busy) response. |
| 239 |
> |
|
| 240 |
> |
25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase. |
| 241 |
> |
|
| 242 |
> |
26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local |
| 243 |
> |
databasenames. These are respectively expanded to the local system's temp directory |
| 244 |
> |
(including trailing delimiter) or to a prescribed data directory (including |
| 245 |
> |
trailing delimiter). Under Unix systems the data directory is a hidden directory |
| 246 |
> |
in the user's home directory. The hidden directory name is either the string returned |
| 247 |
> |
from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'. |
| 248 |
> |
Under Windows, the directory is the same as the Data Directory as decribed |
| 249 |
> |
above but instead prefixed by the User's application data path. These may be |
| 250 |
> |
used to improve application portability for Personal Databases. |
| 251 |
> |
|
| 252 |
> |
27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef |
| 253 |
> |
this has not worked for a long time and is not useful either. FieldDefs should be |
| 254 |
> |
managed using the Fields Editor as with any other dataset. To access the fields |
| 255 |
> |
editor for a TIBTable component, double click on the component. The fields editor |
| 256 |
> |
is then displayed. |
| 257 |
> |
|
| 258 |
> |
28. TIBDatabaseInfo: new properties/function |
| 259 |
> |
* DateDBCreated (returns date/time database created) |
| 260 |
> |
* TransactionCount (returns no. of active transactions) |
| 261 |
> |
* GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only). |
| 262 |
> |
* PagesFree (Firebird 3 or later) |
| 263 |
> |
* PagesUsed (Firebird 3 or later) |
| 264 |
> |
* Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only) |
| 265 |
> |
* EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only) |
| 266 |
> |
|
| 267 |
> |
29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo. |
| 268 |
> |
|
| 269 |
> |
30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later). |
| 270 |
> |
|
| 271 |
> |
31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable |
| 272 |
> |
the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later). |
| 273 |
> |
|
| 274 |
> |
32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced |
| 275 |
> |
in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from |
| 276 |
> |
firing during backup and restore. |
| 277 |
> |
|
| 278 |
> |
33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options |
| 279 |
> |
for verbose output using the new property "StatisticsRequested". |
| 280 |
> |
see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats |
| 281 |
> |
|
| 282 |
> |
34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later). |
| 283 |
> |
|
| 284 |
> |
35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin" |
| 285 |
> |
palette. This uses the online validation feature added in Firebird 2.5. The |
| 286 |
> |
services's properties enable inclusion/exclusion of tables and indexes using |
| 287 |
> |
regular expressions. See. |
| 288 |
> |
https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation |
| 289 |
> |
|
| 290 |
> |
36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger |
| 291 |
> |
option on a database. |
| 292 |
> |
|
| 293 |
> |
37. TIBCustomService: Assign method implemented to allow copying of service login |
| 294 |
> |
context between service API components. "Detach" method now only detaches |
| 295 |
> |
service when last reference to the service interface detaches. Tidy up of |
| 296 |
> |
code for SetActive and Attach methods including password hiding. |
| 297 |
> |
|
| 298 |
> |
38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only |
| 299 |
> |
and used to determine the auth method and protocol used for the connection. |
| 300 |
> |
|
| 301 |
> |
39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using |
| 302 |
> |
a Create Database Statement generated by IBX. |
| 303 |
> |
|
| 304 |

1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf |
| 327 |
> |
changes. |
| 328 |
> |
|
| 329 |
> |
2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString. |
| 330 |
> |
Bug could result in truncated multi-byte character set values. |
| 331 |
> |
|
| 332 |
> |
3. Changes consequential on moving fbintf character set utility functions from |
| 333 |
> |
IFirebirdAPI to IAttachment. |
| 334 |
> |
|
| 335 |
> |
4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true |
| 336 |
> |
|
| 337 |
> |
5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally |
| 338 |
> |
results in autocomplete ignoring prefix text. |
| 339 |
> |
|
| 340 |
> |
6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when |
| 341 |
> |
entering a new name into the text box. |
| 342 |
> |
|
| 343 |
> |
7. IBCustomDataset: ensure that TIBStringField uses the field size reported by |
| 344 |
> |
Firebird rather than recomputing it. |
| 345 |
> |
|
| 346 |
> |
8. Property Editor positioning tidy up: All IBX Property editors should now be |
| 347 |
> |
screen centre. Previously some were "poDesigned" which may be inappropriate |
| 348 |
> |
for multi monitor desktops. |
| 349 |
> |
|
| 350 |
> |
10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node. |
| 351 |
> |
|
| 352 |
> |
11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending |
| 353 |

> |
15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised. |
| 363 |
> |
|
| 364 |
> |
16. IBLocaldb: Drop database if error creating an empty database. |
| 365 |
> |
|
| 366 |
> |
17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset |
| 367 |
> |
unless selected node not in current dataset. |
| 368 |
> |
|
| 369 |
> |
18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package) |
| 370 |
> |
to TIBCustomService, and IBlocalDB code tidy up. |
| 371 |
> |
|
| 372 |
> |
19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable |
| 373 |
> |
behaviour due to uninitialised variable. |
| 374 |
> |
|
| 375 |
> |
20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from |
| 376 |
> |
integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode. |
| 377 |
> |
|
| 378 |
> |
21. IBSQL: When Database changed ensure that all resources are freed. |
| 379 |
> |
|
| 380 |
> |
22. IBCustomDataset: When database changed ensure that queries an unprepared. |
| 381 |
> |
|
| 382 |
> |
23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include: |
| 383 |
> |
* Line Wrap on SQL Token boundaries (on user command) |
| 384 |
> |
* auto-complete table names in drop down list of table names |
| 385 |
> |
* Double click on tablename or field name adds to SQL text |
| 386 |
> |
|
| 387 |
> |
24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d). |
| 388 |
> |
|
| 389 |
> |
25. IBTreeView: Call to FindNode: param type change from "array of Variant" to |
| 390 |
> |
TVariantArray. Seems to avoid memory corruption in Windows (probably a |
| 391 |
> |
workaround for a problem in fpc 3.0.4 win64). |
| 392 |
> |
|
| 393 |
> |
26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open. |
| 394 |

|
| 399 |
> |
1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to |
| 400 |
> |
include remote system name. |
| 401 |
> |
|
| 402 |
> |
2. TIBExtract: No longer include comment header and COMMIT statement for empty |
| 403 |
> |
tables when data included in output. |
| 404 |
> |
|
| 405 |
> |
3. Profiling: IBSQL now has conditional compilation flags to enable query performance |
| 406 |
> |
and timing information to be written to stdout. This may be used to locate |
| 407 |
> |
performance bottlenecks. |
| 408 |
> |
|
| 409 |
> |
4. SQLParser: only call "OnChanging" event handler when value is different. |
| 410 |
> |
|
| 411 |
> |
5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit |
| 412 |
> |
|
| 413 |
> |
6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures |
| 414 |
> |
that BindFields is called when the query is next activated. Avoids FieldName |
| 415 |
> |
not found error. |
| 416 |
> |
|
| 417 |
> |
7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general |
| 418 |
> |
purpose and allows the programmer to define any action they want for Update, Insert |
| 419 |
> |
or Delete. This may be complex SQL (similar to a Trigger), application specific |
| 420 |
> |
filtering of updates, or use of statements such as Grant or Revoke instead of |
| 421 |
> |
normal DML. See User Manual for more information. |

4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements |
| 433 |
> |
using a simple XML format. |
| 434 |

|
| 435 |
> |
5. TIBExtract: extract of individual Triggers and Stored Procedures can now include |
| 436 |
> |
grants to these objects. |
| 437 |
> |
|
| 438 |
> |
6. TIBExtract: Stored Procedures and Views output in dependency order to avoid |
| 439 |
> |
dependency problems restoring complex databases. |
| 440 |
> |
|
| 441 |
> |
7. TIBXScript: This component has been restructured to allow for the processing of |
| 442 |
> |
embedded XML in INSERT statements and to support interactive sources in addition |
| 443 |
> |
to non-interactive data sources such as files. |
| 444 |
> |
|
| 445 |
> |
8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported. |
| 446 |
> |
|
| 447 |
> |
9. TIBXScript: ISQL compatiable Set statements are now supported: |

SET NAMES <character set> |
| 456 |
> |
|
| 457 |
> |
10. IBVersion unit added to hold current IBX Version Number information. |
| 458 |
> |
|
| 459 |
> |
11. TIBExtract: Use character rather than byte length for VarChar procedure arguments., |
| 460 |
> |
and domain definitions. |
| 461 |
> |
|
| 462 |
> |
12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers |
| 463 |
> |
fully supported. |
| 464 |

See also doc/IBX4LazarusGuide.pdf for important information on |

upgrading to IBX2. |

1. Size property of TIBStringField is now the width in characters of the field |
| 475 |
> |
and not the byte length. This applies only to multi-byte character sets such |
| 476 |
> |
as UTF8. The original approach aligned with TStringField. However, the TStringField |
| 477 |
> |
code is not recognised as a bug and hence this change to align the behaviour. |
| 478 |
> |
The TStringField change is expected in fpc 3.2.0. |
| 479 |
> |
|
| 480 |
> |
2. A new property AutoFieldSize: boolean has been added to TIBStringField. When |
| 481 |
> |
true (default) then Size property value saved in the lfm is ignored. Size is |
| 482 |
> |
always set from the dynamic information read from the database. It is unclear |
| 483 |
> |
why anyone would want to override this and set Size to false. |
| 484 |
> |
|
| 485 |
> |
3. ibxscript: should now handle correctly a Case..End statement within a procedure |
| 486 |
> |
block. |
| 487 |
> |
|
| 488 |
> |
4. IBDatabase: new property - CreateIfNotExists. If true and database does not |
| 489 |
> |
exist when an attempt is made to connect to it (run time only) then an attempt |
| 490 |
> |
is made to create the database. |
| 491 |
> |
|
| 492 |
> |
5. IBDatabase: new event - OnCreateDatabase. This event is called after a database |
| 493 |
> |
has been successfully created as a result of a call to CreateDatabase or when |
| 494 |
> |
creating a database after it was found not to exist. |
| 495 |
> |
|
| 496 |
> |
6. DBControlGrid: a race condition could result in the wrong row image being |
| 497 |
> |
written to the cache. This has been avoided by a trip round the message |
| 498 |
> |
loop before rendering the row image. |
| 499 |
> |
|
| 500 |
> |
7. DBControlGrid: It is strongly recommended not to open the source DataSet for |
| 501 |
> |
a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is |
| 502 |
> |
known to risk corrupt rendering of row images when the control is first |
| 503 |
> |
displayed. If necessary use "Application.QueueAsyncCall" to delay opening |
| 504 |
> |
of the dataset (see DBControlGrid examples) until the Form's Window has been created. |
| 505 |
> |
|
| 506 |
> |
8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with |
| 507 |
> |
a TDateEdit control located on an editor panel. |
| 508 |
> |
|
| 509 |
> |
9. TIBExtract: brought up-to-date plus many bug fixes. |
| 510 |
> |
|
| 511 |
> |
10. DBControlGrid: Removed memory leak when updating rows. |
| 512 |
> |
|
| 513 |
> |
11. TIBCMLocalDBSupport: fixed invalid free on upgrade. |
| 514 |

1. IBCustomDataset: When calling SetCodePage, no longer request transliteration |
| 518 |
> |
when target codepage is CP_NONE. This is a workaround for |
| 519 |
> |
http://bugs.freepascal.org/view.php?id=30622. |
| 520 |
> |
|
| 521 |

2. DBLog option removed from TIBStatisticalService - not supported by server |
| 522 |
> |
since Firebird 1.5. |
| 523 |
> |
|
| 524 |
> |
3. ibxscript: An error is no longer generated for "on commit preserve rows" or |
| 525 |
> |
similar. |
| 526 |
> |
|
| 527 |
> |
4. IBCodePage: updated mapping between codepages and character id. |
| 528 |
> |
|
| 529 |
> |
5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in |
| 530 |
> |
Firebird. Character sets with a char width of two are not UTF16. |
| 531 |
> |
|
| 532 |
> |
6. Strings received from the database are now always transliterated into UTF8 |
| 533 |
> |
regardless of the database character set or connection character set. This |
| 534 |
> |
is for compatibility with the LCL. |

1. IBBlob: Defer reading of blob until read method called. This avoids having to |
| 539 |
|
read in an entire blob just to get the size of the blob. General performance |
