3 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
4 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
5 >   mode apps.
6 >
7 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
8 >   statement. This avoids problems if "Execute Block" is used as the Query.
9 >
10 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
11 >   internal SQL tokeniser routines.
12 >
13 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
14 >   as a select statement, with or without CTEs.
15 >
16 > 5. IBSQLParser: parser now recognises the "ROWS" clause.

18 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
19 >   internal SQL tokeniser routines.
20 >
21 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions

32 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
33 >   or param name is not a valid SQL identifier.
34 >
35 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
36 >    view of whether the text box should be editable when no DataSource is specified.
37 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
38 >    ReadOnly is false, the text box is editable when no DataSource is specified.
39 >
40 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
41 >    the FBLIB environment variable. If you do not want to permit this then you
42 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove

52 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
53 > all previous copies of the IBX source code tree before installing this release.
54 >
55 > The IBX packages used by most users have not changed, with one exception. The
56 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
57 > to use the IBServices unit in your applications, please add the iblegacyServices
58 > to the list of dependencies. To do this, open the Project Inspector and select
59 > Add->New Requirement and select "ibLegacyServices" from the list of available
60 > packages.
61 >
62 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
63 >   the IBServices unit providing what is intended to be a clearer and easier to
64 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
65 >   more information and the guide to "Firebird Service Management Using IBX".
66 >   As indicated above, the legacy services components are still available and
67 >   provided in a separate package. There is no need to update working applications
68 >   using the older versions except for an additional package dependency.
69 >
70 > 2. The IBX packages and source code tree have been re-organised in an attempt to
71 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
72 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
73 >   new set of IBX packages.
74 >
75 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
76 >   updated to use the new Services API components.
77 >
78 > 4. The iblocal package has been updated to use the new Services API components.
79 >
80 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
81 >   TIBXSecurityService. It had been wrongly classified in the previous version
82 >   as a per database configuration item. It is global to a server and hence
83 >   correctly positioned as part of the Security Package. In the DBAdmin example,
84 >   the setting has moved to the mappings page.
85 >
86 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
87 >   are ignored.
88 >
89 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
90 >   closed before the database is dropped. Before and After Disconnect event handlers
91 >   are also fired.
92 >
93 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
94 >   is started and not just the first time.
95 >
96 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
97 >   depenendency with comp type.
98 >
99 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
100 >
101 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
102 >    then this is recognised and not ignored.
103 >
104 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
105 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
106 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
107 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
108 >
109 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
110 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
111 >    counters for the select query. Note: stats accumulate after each fetch from
112 >    the database. To get total query cost after open, call the "Last" method
113 >    and then GetPerfStatistics.
114 >
115 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
116 >
117 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
118 >    in parenthesises.
119 >
120 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
121 >    SQL identifiers are always delimited by double quotes. If false, then they are
122 >    only delimited if the identifier is a reserved word, contains lower case or special
123 >    characters. Set this property to true to retain previous behaviour.
124 >
125 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
126 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
127 >
128 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
129 >       property MasterDetailDelay: integer {defaults to zero}
130 >
131 >    When non-zero and the dataset is a detail table referencing a master table
132 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
133 >    then a synchronisation delay is added (in milliseconds) between the master
134 >    row changing and the detail dataset being re-opened. If the master dataset
135 >    is scrolled before the delay expires then the delay is reset. This can be used
136 >    to avoid performance overheads when scrolling through a large master dataset.
137 >
138 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
139 >    chreads unit must be included in your project. TTimer is not used in order
140 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
141 >
142 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
143 >    with Extract Option eoDatabase.
144 >
145 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
146 >    When a deLayoutChanged event is reported on the ListSource dataset, the
147 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
148 >    relationship with the control's datasource (master).
149 >
150 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
151 >
152 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
153 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
154 >
155 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
156 >    DDL (Firebird 3 and later only).
157 >
158 > 22. TIBLookupComboBox Autocomplete Fixes:
159 >    i. Only appended text is now selected after autocomplete.
160 >    ii. Uppercase keys no longer ignored for autocomplete.
161 >    iii. Retain Prefix case is now honoured correctly.
162 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
163 >        before autocomplete performed. i.e. behaviour now the same as when
164 >        no DataSource assigned.
165 >
166 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
167 >    between SQL statements.
168 >
169 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
170 >    ObjectNames are converted to upper case before matching against metadata object
171 >    names, unless the objectname is delimited by double quotes, in which case, the
172 >    double quotes are removed and the remaining string is used (unmodified) to match
173 >    against the metadata object name.
174 >
175 >    If true then the ObjectName is used as is without modification and matched
176 >    against the metadata object name. No attempt is made to remove double quotes.
177 >
178 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
179 >    with eoTrigger, these extract types can be used to select only Database Triggers,
180 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
181 >
182 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
183 >    statement separate character is now reset to the default (';').
184 >
185 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
186 >
187 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
188 >    a commit or reconnect statement and instead activated only when next SQL statement
189 >    is executed.
190 >
191 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
192 >
193 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
194 >    converting statement to upper case.
195 >
196 > 31. TIBExtract: metadata comments now supported. New published property
197 >    IncludeMetaDataComments (default true). If true then metadata comments included
198 >    in extracted DDL. New Extract Object member eoComments. This may be used with
199 >    ExtractObject method to list all metadata comments.
200 >
201 > 32. TIBExtract: ListObjectNames method added.
202 >
203 > 33. Updated Database component editor to support additional connection string
204 >    types.
205 >
206 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
207 >
208 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
209 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
210 > RELEASE.
211 >
212 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
213  
214   1. IBExtract: Identity columns - add additional check for null column for generator name.
215  
# Line 15 | Line 226 | IBX Change Log  version
226     a returning clause that updates one or more fields on the current row. A full row
227     refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
228     field values and the select query contains read only fields. Use of Insert/update
229 <   returning should be significantly more efficient than excuting a refresh query.
229 >   returning should be significantly more efficient than executing a refresh query.
230  
231     This behaviour change is intended to be backwards compatible and there should be no need to change
232     existing programs, other than to improve performance by using the new capability.
233  
234 < 3. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
234 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
235 >   they are called when the dataset row is being deleted, there is no value in
236 >   updating the current record from the query result. Instead, a new event handler
237 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
238 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
239 >   by the query. The event handler can then interrogate the query results and
240 >   perform whatever action is necessary. For example to confirm, to the user,
241 >   the deletion of a row with the returned values.
242 >
243 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
244     any Computed By or Identity Columns. The IBTables example has been updated to
245     illustrate the computation of the employee Full Name on update.
246  
247 < 4. TIBTable: The GeneratorField property is now published.
247 > 5. TIBTable: The GeneratorField property is now published.
248  
249 < 5. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
249 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
250     When InsertSQL is generated, the Identity columns are not included in the list of values to
251     be inserted. A RETURNING clause is added to the insert statement to return the value of
252     each Identity column after the insert is executed.
253  
254 < 6. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
254 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
255     Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
256     Insert..Returning clause.
257  
258 < 7. TIBGenerator: small performance improvement by not preparing query each time
258 > 8. TIBGenerator: small performance improvement by not preparing query each time
259     a new value is generated.
260  
261 < 8. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
261 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
262  
263 < 9. Property editors will now sync table name to a System Table when "Include System
264 <   Tables" is selected and the query is for a System Table.
263 > 10. Property editors will now sync table name to a System Table when "Include System
264 >    Tables" is selected and the query is for a System Table.
265  
266 < 10. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
266 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
267      values are no longer converted to milliseconds from TDateTime and then back again
268      to TDateTime (the conversion to milliseconds is the default TDataset approach).
269  
270 < 11. Property Editors handling of Stored Procedures.
270 > 12. Property Editors handling of Stored Procedures.
271      * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
272        which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
273        query).
274      * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
275  
276 < 12. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
276 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
277      can be used to select a package. If non-empty, the stored procedure name is
278      expected to be a stored procedure defined in the specified package and the
279      generated SQL will be as required for a stored procedure located in a package.
280  
281 < 13. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
281 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
282      a "Package Name" drop down box to allow selection of a Firebird 3 Package from
283      which a stored procedure can be selected. With no package name selected, non-package
284      stored procedures are listed.
285  
286 < 14. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
286 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
287      for password on reconnect.
288  
289 + 16. TIBDatabase: use IAttachment for connection default character set id, code page
290 +    and character set name.
291 +
292 + 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
293 +    DB info lookups"
294 +
295 + 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
296 +
297 + 19. Add a property Editor for TIBUpdate.RefreshSQL.
298 +
299 + 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
300 +    parameters. This stops an exception being raised when the field cannot be
301 +    located in the record buffer.
302 +
303 + 21. Property Editors now automatically include System Tables when opened and when the query table
304 +    is a System Table.
305 +
306 + 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
307 +    This avoids errors due to a stale SQRB or SRB being used for the next query.
308 +
309 + 23. IBServices: Service attach parameters now include "expected_db". This is used to
310 +    add the SPB item isc_spb_expected_db. This names a database using
311 +    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
312 +    database. examples/services re-written to illustrate use of "expected_db".
313 +
314 + 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
315 +    This avoids truncated backups when the server returns a timeout (busy) response.
316 +
317 + 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
318 +
319 + 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
320 +    databasenames. These are respectively expanded to the local system's temp directory
321 +    (including trailing delimiter) or to a prescribed data directory (including
322 +    trailing delimiter). Under Unix systems the data directory is a hidden directory
323 +    in the user's home directory. The hidden directory name is either the string returned
324 +    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
325 +    Under Windows, the directory is the same as the Data Directory as decribed
326 +    above but instead prefixed by the User's application data path. These may be
327 +    used to improve application portability for Personal Databases.
328 +
329 + 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
330 +    this has not worked for a long time and is not useful either. FieldDefs should be
331 +    managed using the Fields Editor as with any other dataset. To access the fields
332 +    editor for a TIBTable component, double click on the component. The fields editor
333 +    is then displayed.
334 +
335 + 28. TIBDatabaseInfo: new properties/function
336 +     * DateDBCreated (returns date/time database created)
337 +     * TransactionCount (returns no. of active transactions)
338 +     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
339 +     * PagesFree (Firebird 3 or later)
340 +     * PagesUsed (Firebird 3 or later)
341 +     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
342 +     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
343 +
344 + 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
345 +
346 + 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
347 +
348 + 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
349 +    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
350 +
351 + 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
352 +    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
353 +    firing during backup and restore.
354 +
355 + 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
356 +    for verbose output using the new property "StatisticsRequested".
357 +    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
358 +
359 + 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
360 +
361 + 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
362 +    palette. This uses the online validation feature added in Firebird 2.5. The
363 +    services's properties enable inclusion/exclusion of tables and indexes using
364 +    regular expressions. See.
365 +    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
366 +
367 + 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
368 +    option on a database.
369 +
370 + 37. TIBCustomService: Assign method implemented to allow copying of service login
371 +    context between service API components. "Detach" method now only detaches
372 +    service when last reference to the service interface detaches. Tidy up of
373 +    code for SetActive and Attach methods including password hiding.
374 +
375 + 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
376 +    and used to determine the auth method and protocol used for the connection.
377 +
378 + 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
379 +    a Create Database Statement generated by IBX.
380 +
381 + 40. All IBServices now have an additional published property "PortNo". This may
382 +    be set to a non-standard port number when necessary. If zero then the default
383 +    port number is used.
384 +
385 + 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
386 +    and not just the mouse.
387 +
388 + 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
389 +
390 + 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
391 +    image index and selected image index for each node to be set from a database field.
392 +
393 + 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
394 +    then database schema includes grants to all users. If not present then the
395 +    only user grants included are those to User PUBLIC.
396 +
397 + 45. TIBTreeView: performance improvement. When expanding include both expanded node
398 +    and child nodes in dataset.
