2 >
3 > 1. Firebird 4 support added.
4 >
5 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
6 >   extended precision NUMERIC fields are supported.
7 >
8 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
9 >
10 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
11 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
12 >
13 > 5. IBExtract now supports FB4 enhancements:
14 >   - new data types as above
15 >   - Identity column extensions
16 >   - Default user role
17 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
18 >   - Internal Functions
19 >
20 > 6. IBExtract: new event: OnExtractLines.
21 >
22 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
23 >
24 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
25 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
26 >
27 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
28 >   format for rendering a time zone.
29 >
30 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
31 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
32 >
33 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
34 >    IIBGUIInterface and IIBTimerInf respectively.
35 >
36 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
37 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
38 >
39 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
40 >    truncated to its fixed character width rather than being right padded with
41 >    white space to the maximum data size.
42 >
43 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
44 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
45 >    also empty.
46 >
47 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
48 >
49 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
50 >    connect string. The database name is extracted from the connect string.
51 >
52 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
53 >
54 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
55 >
56 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
57 >    not being present as required.
58 >
59 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
60 >    version that can be customised to work with other database drivers.
61 >
62 > IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
63 >
64 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
65 >    number of UTF8 characters exceeds the string size then string is truncated
66 >    to the maximum string size. This is  usually a problem with fixed width columns
67 >    right padded with white space.
68 >
69 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
70 >    If SQLFiltered is set then when a dataset is opened, each line in the
71 >    SQLFilterParams property is assumed to be a SQL condition clause and
72 >    ANDed into the Where clause of the SQL Select statement provided as a
73 >    dataset property. Each such SQL condition thus acts as an additional filter
74 >    on the dataset.
75 >
76 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
77 >    side filters).
78 >
79 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
80 >   text matches complete entry.
81 >
82 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
83 >   dataset are active (avoids risk of access violation if master is inactive)
84 >
85 > 6. TIBEvents: Registered property can now be set at design time even if database not open
86 >
87 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
88 >   This should prevent "spillover" of events between sessions.
89 >
90 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
91 >   This should ensure that the internal buffer is set up correctly and avoids
92 >   a duplicate initial row.
93 >
94 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
95 >   That is, the DataSize should be the field size * character set width. The
96 >   value returned by DataSize is now the same as the Dataset buffer size reserved
97 >   for the field.
98 >
99 > 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
100 >
101 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
102 >    and vice-versa. This may result in an exception being raised (correctly) for
103 >    older programs when using dataset fields added to a form and the database has been
104 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
105 >    In such cases, the field needs to be deleted in the IDE fields editor and then
106 >    added back in.
107 >
108 > 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
109 >    false if query contains only white space and not just empty.
110 >
111 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
112 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
113 >    is cancelled.
114 >
115 > 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
116 >    called on a null field.
117 >
118 > 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
119 >    results in an empty dataTC86                Client side Filtered Dataset    1       X
120 > set.
121 >
122 > 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
123 >    a cached update is applied and an exception is raised.
124 >
125 > 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
126 >
127 > 17. Console Mode Local Database support: backup/restore should now work correctly.
128 >
129 > 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
130 >    possible and an exception raised.
131 >
132 > 19. MinimumVersionNo added to Local Database Support. Database will not open if
133 >    below this version no. and upgrade not possible.

136 >
137 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
138 >    not SQL Identifiers are now supported.
139 >
140 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
141 >    passed to the Firebird engine for execution.
142 >
143 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
144 >    is made to scroll back.
145 >
146 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
147 >
148 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
149 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
150 >
151 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
152 >   validated. If no match is found in the list of field names and the database has
153 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
154 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
155 >
156 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
157 >   with fpc 3.2.

161  
162   1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
163     and is used to override the default settings in the client side "firebird.conf" This
# Line 62 | Line 221 | IBX Change Log  version (2.3-3 Build 113
221     This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
222  
223   8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
224 +   Uses "FindParam" if in order to find out if a parameter with a given name exists
225 +   and without raising and exception if it does not.
226  
227 < 9. TIBQuery now uses IBX SQL Parser instead of TParams SQL parser in order to ensure
227 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
228     consistency with SQL queries.
229  
230   10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
231      When true, SQL statement parameter names are parsed case sensitive. Note for
232      TIBDataSet only applies to Select query.
233  
234 + 11. IBEvents: removing a TIBEvent component from a form should no longer result in
235 +    an IDE exception.
236 +
237 + 12. LocalDBSupport: initial database creation should now work correctly
238 +    when the schema source is an sql file.
239 +
240 + 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
241 +    when defined, this handler will be called by the internal TIBXScript during
242 +    initial database creation when the schema source is an sql file and may be used
243 +    to provide a visual indication of progress in console mode.
244 +
245 + 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
246 +    to true while a new local database is being created and its schema populated.
247 +    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
248 +    when the database is disconnected/connected during the create DB procedure.
249 +
250 + 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
251 +    are now always ignored and replaced by the user name and password provided as
252 +    the login parameters for the TIBDatabase referenced from the TIBXScript. The
253 +    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
254 +    completely ignored if this property is true.
255 +
256 + 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
257 +    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
258 +    ImageIndex and SelectImageIndex values on AddNode.
259 +
260 + 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
261 +    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
262 +    the same database connection.
263 +
264 + 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
265 +    if provided, this should be an conditional SQL expression suitable for
266 +    including in an SQL Select statement "where" clause. If non-empty and the
267 +    "Filtered" property is true then the SQL expression provided as the value of
268 +    the "Filter" property is "ANDed" with any existing condition statement
269 +    in the SQL statement's "Where" clause.
270 +
271 +    If the "Filter" property is set at run time, the "Filtered" property is true
272 +    and the dataset is already open, then the dataset is closed and re-opened automatically.
273 +
274 +    The "Filter" condition may include IBX style parameters. In which case, their
275 +    value must be set by the dataset's "OnBeforeOpen" event handler.
276 +
277 +    This is a public property for TIBDataSet and TIBQuery query and intended for
278 +    use at run time.
279 +
280 +    Note: The property is a published property of TIBTable. The TIBTable functionality
281 +    is unaffected by this change.
