2 >
3 > 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. TIBDatabase: 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 and Grants to DDL objects.
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. IBServices: SQRB and SRB buffers are now reset when service query throws and exception.
96 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
97 >
98 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
99 >    add the SPB item isc_spb_expected_db. This names a database using
100 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
101 >    database. examples/services re-written to illustrate use of "expected_db".
102 >
103 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
104 >    This avoids truncated backups when the server returns a timeout (busy) response.
105 >
106 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
107 >
108 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
109 >    databasenames. These are respectively expanded to the local system's temp directory
110 >    (including trailing delimiter) or to a directory a prescribed data directory (including
111 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
112 >    in the user's home directory. The hidden directory name is either the string returned
113 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
114 >    Under Windows, the directory is the same as the Data Directory as decribed
115 >    above but instead prefixed by the User's application data path. These may be
116 >    used to improve application portability.
117 >
118 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
119 >    this has not worked for a long time and is not useful either. FieldDefs should be
120 >    managed using the Fields Editor as with any other dataset. To access the fields
121 >    editor for a TIBTable component, double click on the component. The fields editor
122 >    is then displayed.
123 >
124 > 28. TIBDatabaseInfo: new properties/function
125 >     * DateDBCreated (returns date/time database created)
126 >     * TransactionCount (returns no. of active transactions)
127 >     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
128 >     * PagesFree (Firebird 3 or later)
129 >     * PagesUsed (Firebird 3 or later)
130 >     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
131 >     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
132 >
133 > 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
134 >
135 > 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
136 >
137 > 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
138 >    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
139 >
140 > 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
141 >    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
142 >    firing during backup and restore.
143 >
144 > 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
145 >    for verbose output using the new property "StatisticsRequested".
146 >    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
147 >
148 > 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
149 >
150 > 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
151 >    palette. This uses the online validation feature added in Firebird 2.5. The
152 >    services's properties enable inclusion/exclusion of tables and indexes using
153 >    regular expressions. See.
154 >    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
155 >
156 > 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
157 >    option on a database.
158 >
159 > 37. TIBCustomService: Assign method implemented to allow copying of service login
160 >    context between service API components. "Detach" method now only detaches
161 >    service when last reference to the service interface detaches. Tidy up of
162 >    code for SetActive and Attach methods including password hiding.
163 >
164 > 38. TIBDatabase: new proterties: AuthenticationMethod and RemoteProtocol. Read only
165 >    and used to determine the auth method and protocol used for the connection.
166 >
167 > 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
168 >    a Create Database Statement generated by IBX.
169 >
170 > 40. All IBServices now have an additional published property "PortNo". This may
171 >    be set to a non-standard port number when necessary. If zero then the default
172 >    port number is used.
173 >
174 > 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
175 >    and not just the mouse.
176 >
177 > 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
178 >
179 > 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
180 >    image index and selected image index for each node to be set from a database field.
181 >
182 > 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
183 >    then database schema includes grants to all users. If not present then the
184 >    only user grants included are those to User PUBLIC.
185 >
186 > 45. TIBTreeView: performance improvement. When expanding include both expanded node
187 >    and child nodes in dataset.

190 > IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
191  
192   1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
193     changes.
# Line 20 | Line 209 | IBX Change Log  version
209   7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
210     Firebird rather than recomputing it.
211  
212 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
213 +   screen centre. Previously some were "poDesigned" which may be inappropriate
214 +   for multi monitor desktops.
215 +
216 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
217 +
218 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
219 +    a transaction and always reset the object.
220 +
221 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
222 +
223 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
224 +
225 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
226 +    to a gbak format archive.
227 +
228 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
229 +
230 + 16. IBLocaldb: Drop database if error creating an empty database.
231 +
232 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
233 +    unless selected node not in current dataset.
234 +
235 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
236 +    to TIBCustomService, and IBlocalDB code tidy up.
237 +
238 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
239 +    behaviour due to uninitialised variable.
240 +
241 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
242 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
243 +
244 + 21. IBSQL: When Database changed ensure that all resources are freed.
245 +
246 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
247 +
248 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
249 +    * Line Wrap on SQL Token boundaries (on user command)
250 +    * auto-complete table names in drop down list of table names
251 +    * Double click on tablename or field name adds to SQL text
252 +
253 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
254 +
255 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
256 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
257 +    workaround for a problem in fpc 3.0.4 win64).
258 +
259 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
260 +
261 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
262 +
263   IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
264  
265   1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
# Line 40 | Line 280 | IBX Change Log  version
280     that BindFields is called when the query is next activated. Avoids FieldName
281     not found error.
282  
283 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
284 +   purpose and allows the programmer to define any action they want for Update, Insert
285 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
286 +   filtering of updates, or use of statements such as Grant or Revoke instead of
287 +   normal DML. See User Manual for more information.
288 +
289   IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
290  
291   1. TIBEvents: Fix uninitialised variable that could result in lost events.
