10  
11   2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
12     The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
13 <   information). Values returned as a result of executing an Insert or Update statement
14 <   replace existing values in the current row for each corresponding column.
13 >   information). However, this is also a very useful mechanism for returning updated computed by
14 >   column values. Values returned as a result of executing an Insert or Update statement
15 >   replace existing values in the current row for each corresponding column.
16 >
17 >   Previously, if a dataset's select query included read only (computed by) fields then
18 >   an automatic row refresh was performed after an insert or update query had been processed,
19 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
20 >   that an automatic refresh is no longer performed if an insert or update query contains
21 >   a returning clause that updates one or more fields on the current row. A full row
22 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
23 >   field values and the select query contains read only fields. Use of Insert/update
24 >   returning should be significantly more efficient than executing a refresh query.
25 >
26 >   This behaviour change is intended to be backwards compatible and there should be no need to change
27 >   existing programs, other than to improve performance by using the new capability.
28 >
29 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
30 >   they are called when the dataset row is being deleted, there is no value in
31 >   updating the current record from the query result. Instead, a new event handler
32 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
33 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
34 >   by the query. The event handler can then interrogate the query results and
35 >   perform whatever action is necessary. For example to confirm, to the user,
36 >   the deletion of a row with the returned values.
37 >
38 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
39 >   any Computed By or Identity Columns. The IBTables example has been updated to
40 >   illustrate the computation of the employee Full Name on update.
41 >
42 > 5. TIBTable: The GeneratorField property is now published.
43  
44 < 3. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
44 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
45     When InsertSQL is generated, the Identity columns are not included in the list of values to
46     be inserted. A RETURNING clause is added to the insert statement to return the value of
47     each Identity column after the insert is executed.
48  
49 < 4. TIBGenerator: small performance improvement by not preparing query each time
50 <   a new number is generated.
49 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
50 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
51 >   Insert..Returning clause.
52  
53 < 5. TIBSQL: Free resources when transaction changed.
53 > 8. TIBGenerator: small performance improvement by not preparing query each time
54 >   a new value is generated.
55  
56 < 6. Property editor will now sync table name to a System Table when "Include System
21 <   Tables" is selected and the query is for a System Table.
56 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
57  
58 < 7. Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
59 <   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
60 <   Insert..Returning clause.
58 > 10. Property editors will now sync table name to a System Table when "Include System
59 >    Tables" is selected and the query is for a System Table.
60 >
61 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
62 >    values are no longer converted to milliseconds from TDateTime and then back again
63 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
64 >
65 > 12. Property Editors handling of Stored Procedures.
66 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
67 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
68 >      query).
69 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
70 >
71 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
72 >    can be used to select a package. If non-empty, the stored procedure name is
73 >    expected to be a stored procedure defined in the specified package and the
74 >    generated SQL will be as required for a stored procedure located in a package.
75 >
76 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
77 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
78 >    which a stored procedure can be selected. With no package name selected, non-package
79 >    stored procedures are listed.
80 >
81 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
82 >    for password on reconnect.
83 >
84 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
85 >    and character set name.
86 >
87 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
88 >    DB info lookups"
89 >
90 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
91 >
92 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
93 >
94 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
95 >    parameters. This stops an exception being raised when the field cannot be
96 >    located in the record buffer.
97 >
98 > 21. Property Editors now automatically include System Tables when opened and when the query table
99 >    is a System Table.
100 >
101 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
102 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
103 >
104 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
105 >    add the SPB item isc_spb_expected_db. This names a database using
106 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
107 >    database. examples/services re-written to illustrate use of "expected_db".
108 >
109 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
110 >    This avoids truncated backups when the server returns a timeout (busy) response.
111 >
112 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
113 >
114 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
115 >    databasenames. These are respectively expanded to the local system's temp directory
116 >    (including trailing delimiter) or to a prescribed data directory (including
117 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
118 >    in the user's home directory. The hidden directory name is either the string returned
119 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
120 >    Under Windows, the directory is the same as the Data Directory as decribed
121 >    above but instead prefixed by the User's application data path. These may be
122 >    used to improve application portability for Personal Databases.
123 >
124 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
125 >    this has not worked for a long time and is not useful either. FieldDefs should be
126 >    managed using the Fields Editor as with any other dataset. To access the fields
127 >    editor for a TIBTable component, double click on the component. The fields editor
128 >    is then displayed.
129 >
130 > 28. TIBDatabaseInfo: new properties/function
131 >     * DateDBCreated (returns date/time database created)
132 >     * TransactionCount (returns no. of active transactions)
133 >     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
134 >     * PagesFree (Firebird 3 or later)
135 >     * PagesUsed (Firebird 3 or later)
136 >     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
137 >     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
138 >
139 > 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
140 >
141 > 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
142 >
143 > 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
144 >    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
145 >
146 > 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
147 >    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
148 >    firing during backup and restore.
149 >
150 > 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
151 >    for verbose output using the new property "StatisticsRequested".
152 >    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
153 >
154 > 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
155 >
156 > 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
157 >    palette. This uses the online validation feature added in Firebird 2.5. The
158 >    services's properties enable inclusion/exclusion of tables and indexes using
159 >    regular expressions. See.
160 >    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
161 >
162 > 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
163 >    option on a database.
164 >
165 > 37. TIBCustomService: Assign method implemented to allow copying of service login
166 >    context between service API components. "Detach" method now only detaches
167 >    service when last reference to the service interface detaches. Tidy up of
168 >    code for SetActive and Attach methods including password hiding.
169 >
170 > 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
171 >    and used to determine the auth method and protocol used for the connection.
172 >
173 > 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
174 >    a Create Database Statement generated by IBX.
175 >
176 > 40. All IBServices now have an additional published property "PortNo". This may
177 >    be set to a non-standard port number when necessary. If zero then the default
178 >    port number is used.
179 >
180 > 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
181 >    and not just the mouse.
182 >
183 > 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
184 >
185 > 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
186 >    image index and selected image index for each node to be set from a database field.
187 >
188 > 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
189 >    then database schema includes grants to all users. If not present then the
190 >    only user grants included are those to User PUBLIC.
191 >
192 > 45. TIBTreeView: performance improvement. When expanding include both expanded node
193 >    and child nodes in dataset.
194  
27 8. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
28   values are no longer converted to milliseconds from TDateTime and then back again
29   the TDateTime (the TDataset approach).
