1	+	IBX Change Log  version                                                     (2.2-0) Sun, 25 Feb 2018 08:49:41 +0000
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.
188	+
