2 >
3 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
4 >    number of UTF8 characters exceeds the string size then string is truncated
5 >    to the maximum string size. This is  usually a problem with fixed width columns
6 >    right padded with white space.
7 >
8 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
9 >    If SQLFiltered is set then when a dataset is opened, each line in the
10 >    SQLFilterParams property is assumed to be a SQL condition clause and
11 >    ANDed into the Where clause of the SQL Select statement provided as a
12 >    dataset property. Each such SQL condition thus acts as an additional filter
13 >    on the dataset. (Not yet tested)
14 >
15 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
16 >    side filters).
17 >
18 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
19 >   text matches complete entry.
20 >
21 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
22 >   dataset are active (avoids risk of access violation if master is inactive)
23 >
24 > 6. TIBEvents: Registered property can now be set at design time even if database not open
25 >
26 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
27 >   This should prevent "spillover" of events between sessions.
28 >
29 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
30 >   This should ensure that the internal buffer is set up correctly and avoids
31 >   a duplicate initial row.
32 >
33 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
34 >   That is, the DataSize should be the field size * character set width. The
35 >   value returned by DataSize is now the same as the Dataset buffer size reserved
36 >   for the field.
37 >
38 > 10. IBExtact: Tidyup of SQL generation. Avoid unnecessary double quotes.
39 >
40 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
41 >    and vice-versa. This may result in an exception being raised (correctly) for
42 >    older programs when using dataset fields added to a form and the database has been
43 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
44 >    In such cases, the field needs to be deleted in the IDE fields editor and then
45 >    added back in.
46 >
47 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
48 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
49 >    is cancelled.
50 >
51 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
52 >
53 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
54 >    not SQL Identifiers are now supported.
55 >
56 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
57 >    passed to the Firebird engine for execution.
58 >
59 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
60 >    is made to scroll back.
61 >
62 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
63 >
64 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
65 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
66 >
67 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
68 >   validated. If no match is found in the list of field names and the database has
69 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
70 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
71 >
72 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
73 >   with fpc 3.2.
74 >
75 > IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
76 >
77 >
78 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
79 >   and is used to override the default settings in the client side "firebird.conf" This
80 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
81 >   Each line of the string list should be a setting in the same format as "firebird.conf".
82 >   For example "WireCompression = true" in order to request wire compression on the client side.
83 >
84 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
85 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
86 >   also require a compatible setting in the server side "firebird.conf". For example
87 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
88 >   compression to be used.
89 >
90 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
91 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
92 >   ibx/examples/dbinfo for examples of how to display this information.
93 >
94 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
95 >   is a "convenience" property. If set the "WireCompression=true" is added to the
96 >   ConfigOverrides. If unchecked then this setting is removed.
97 >
98 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
99 >   not "INT64".
100 >
101 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
102 >   These are:
103 >    property TimestampFormat: string;
104 >    property DateFormat: string;
105 >    property TimeFormat: string;
106 >
107 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
108 >   DATETIME and TIME. The format strings use the standard FPC date/time format
109 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
110 >
111 >   If any of the above properties are set to an empty string, then the locale default
112 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
113 >   locale default is extended by appending '.zzz' to include milliseconds.
114 >
115 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
116 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
117 >
118 > 5. New published property for TIBCSVDataOut:
119 >     property QuoteStrings: boolean (default true)
120 >
121 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
122 >   used to delimit each and every string in the output.
123 >
124 > 6. New published properties for TIBCSVDataOut:
125 >    property FieldSeparator: string;
126 >    property HeaderSeparator: string;
127 >
128 >   Respectively, these provide the separator character(s) used to separate fields
129 >   in data and header rows. Both default to ','.
130 >
131 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
132 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
133 >    property OnFormatTextString;
134 >
135 >   This event handler can be used to process text strings before they are included
136 >   in the output e.g. to replace unprintable characters with alternative strings.
137 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
138 >
139 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
140 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
141 >   and without raising and exception if it does not.
142 >
143 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
144 >   consistency with SQL queries.
145 >
146 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
147 >    When true, SQL statement parameter names are parsed case sensitive. Note for
148 >    TIBDataSet only applies to Select query.
149 >
150 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
151 >    an IDE exception.
152 >
153 > 12. LocalDBSupport: initial database creation should now work correctly
154 >    when the schema source is an sql file.
155 >
156 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
157 >    when defined, this handler will be called by the internal TIBXScript during
158 >    initial database creation when the schema source is an sql file and may be used
159 >    to provide a visual indication of progress in console mode.
160 >
161 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
162 >    to true while a new local database is being created and its schema populated.
163 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
164 >    when the database is disconnected/connected during the create DB procedure.
165 >
166 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
167 >    are now always ignored and replaced by the user name and password provided as
168 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
169 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
170 >    completely ignored if this property is true.
171 >
172 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
173 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
174 >    ImageIndex and SelectImageIndex values on AddNode.
175 >
176 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
177 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
178 >    the same database connection.
179 >
180 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
181 >    if provided, this should be an conditional SQL expression suitable for
182 >    including in an SQL Select statement "where" clause. If non-empty and the
183 >    "Filtered" property is true then the SQL expression provided as the value of
184 >    the "Filter" property is "ANDed" with any existing condition statement
185 >    in the SQL statement's "Where" clause.
186 >
187 >    If the "Filter" property is set at run time, the "Filtered" property is true
188 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
189 >
190 >    The "Filter" condition may include IBX style parameters. In which case, their
191 >    value must be set by the dataset's "OnBeforeOpen" event handler.
192 >
193 >    This is a public property for TIBDataSet and TIBQuery query and intended for
194 >    use at run time.
195 >
196 >    Note: The property is a published property of TIBTable. The TIBTable functionality
197 >    is unaffected by this change.
198 >
199 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
200 >
201 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
202 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
203 >   mode apps.
204 >
205 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
206 >   statement. This avoids problems if "Execute Block" is used as the Query.
207 >
208 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
209 >   internal SQL tokeniser routines.
210 >
211 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
212 >   as a select statement, with or without CTEs.
213 >
214 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
215 >
216 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
217 >   internal SQL tokeniser routines.
218 >
219 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
220 >    being raised for valid set statements processed by a data formatter.
221 >
222 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
223 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
224 >   the path of the Firebird Library used by the database/services connection.
225 >
226 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
227 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
228 >   services connection.
229 >
230 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
231 >   or param name is not a valid SQL identifier.
232 >
233 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
234 >    view of whether the text box should be editable when no DataSource is specified.
235 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
236 >    ReadOnly is false, the text box is editable when no DataSource is specified.
237 >
238 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
239 >    the FBLIB environment variable. If you do not want to permit this then you
240 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
241 >    this setting.

250   IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
251   all previous copies of the IBX source code tree before installing this release.
# Line 130 | Line 377 | packages.
377      with eoTrigger, these extract types can be used to select only Database Triggers,
378      or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
379  
380 + 26. TIBXScript: If an exception occurs during the processing of a statement, the
381 +    statement separate character is now reset to the default (';').
382 +
383 + 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
384 +
385 + 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
386 +    a commit or reconnect statement and instead activated only when next SQL statement
387 +    is executed.
388 +
389 + 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
390 +
391 + 30. TIBXScript: case insensitive regex now used when matching statements instead of
392 +    converting statement to upper case.
393 +
394 + 31. TIBExtract: metadata comments now supported. New published property
395 +    IncludeMetaDataComments (default true). If true then metadata comments included
396 +    in extracted DDL. New Extract Object member eoComments. This may be used with
397 +    ExtractObject method to list all metadata comments.
398 +
399 + 32. TIBExtract: ListObjectNames method added.
400 +
401 + 33. Updated Database component editor to support additional connection string
