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 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
19 >
20 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
21 >    not SQL Identifiers are now supported.
22 >
23 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
24 >    passed to the Firebird engine for execution.
25 >
26 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
27 >    is made to scroll back.
28 >
29 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
30 >
31 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
32 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
33 >
34 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
35 >   validated. If no match is found in the list of field names and the database has
36 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
37 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
38 >
39 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
40 >   with fpc 3.2.

43 >
44 >
45 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
46 >   and is used to override the default settings in the client side "firebird.conf" This
47 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
48 >   Each line of the string list should be a setting in the same format as "firebird.conf".
49 >   For example "WireCompression = true" in order to request wire compression on the client side.
50 >
51 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
52 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
53 >   also require a compatible setting in the server side "firebird.conf". For example
54 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
55 >   compression to be used.
56 >
57 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
58 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
59 >   ibx/examples/dbinfo for examples of how to display this information.
60 >
61 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
62 >   is a "convenience" property. If set the "WireCompression=true" is added to the
63 >   ConfigOverrides. If unchecked then this setting is removed.
64 >
65 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
66 >   not "INT64".
67 >
68 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
69 >   These are:
70 >    property TimestampFormat: string;
71 >    property DateFormat: string;
72 >    property TimeFormat: string;
73 >
74 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
75 >   DATETIME and TIME. The format strings use the standard FPC date/time format
76 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
77 >
78 >   If any of the above properties are set to an empty string, then the locale default
79 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
80 >   locale default is extended by appending '.zzz' to include milliseconds.
81 >
82 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
83 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
84 >
85 > 5. New published property for TIBCSVDataOut:
86 >     property QuoteStrings: boolean (default true)
87 >
88 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
89 >   used to delimit each and every string in the output.
90 >
91 > 6. New published properties for TIBCSVDataOut:
92 >    property FieldSeparator: string;
93 >    property HeaderSeparator: string;
94 >
95 >   Respectively, these provide the separator character(s) used to separate fields
96 >   in data and header rows. Both default to ','.
97 >
98 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
99 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
100 >    property OnFormatTextString;
101 >
102 >   This event handler can be used to process text strings before they are included
103 >   in the output e.g. to replace unprintable characters with alternative strings.
104 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
105 >
106 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
107 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
108 >   and without raising and exception if it does not.
109 >
110 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
111 >   consistency with SQL queries.
112 >
113 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
114 >    When true, SQL statement parameter names are parsed case sensitive. Note for
115 >    TIBDataSet only applies to Select query.
116 >
117 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
118 >    an IDE exception.
119 >
120 > 12. LocalDBSupport: initial database creation should now work correctly
121 >    when the schema source is an sql file.
122 >
123 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
124 >    when defined, this handler will be called by the internal TIBXScript during
125 >    initial database creation when the schema source is an sql file and may be used
126 >    to provide a visual indication of progress in console mode.
127 >
128 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
129 >    to true while a new local database is being created and its schema populated.
130 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
131 >    when the database is disconnected/connected during the create DB procedure.
132 >
133 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
134 >    are now always ignored and replaced by the user name and password provided as
135 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
136 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
137 >    completely ignored if this property is true.
138 >
139 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
140 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
141 >    ImageIndex and SelectImageIndex values on AddNode.
142 >
143 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
144 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
145 >    the same database connection.
146 >
147 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
148 >    if provided, this should be an conditional SQL expression suitable for
149 >    including in an SQL Select statement "where" clause. If non-empty and the
150 >    "Filtered" property is true then the SQL expression provided as the value of
151 >    the "Filter" property is "ANDed" with any existing condition statement
152 >    in the SQL statement's "Where" clause.
153 >
154 >    If the "Filter" property is set at run time, the "Filtered" property is true
155 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
156 >
157 >    The "Filter" condition may include IBX style parameters. In which case, their
158 >    value must be set by the dataset's "OnBeforeOpen" event handler.
159 >
160 >    This is a public property for TIBDataSet and TIBQuery query and intended for
161 >    use at run time.
162 >
163 >    Note: The property is a published property of TIBTable. The TIBTable functionality
164 >    is unaffected by this change.
165 >
166 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
167 >
168 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
169 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
170 >   mode apps.
171 >
172 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
173 >   statement. This avoids problems if "Execute Block" is used as the Query.
174 >
175 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
176 >   internal SQL tokeniser routines.
177 >
178 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
179 >   as a select statement, with or without CTEs.
180 >
181 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
182 >
183 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
184 >   internal SQL tokeniser routines.
185 >
186 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
187 >    being raised for valid set statements processed by a data formatter.
188 >
189 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
190 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
191 >   the path of the Firebird Library used by the database/services connection.
192 >
193 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
194 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
195 >   services connection.
196 >
197 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
198 >   or param name is not a valid SQL identifier.
199 >
200 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
201 >    view of whether the text box should be editable when no DataSource is specified.
202 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
203 >    ReadOnly is false, the text box is editable when no DataSource is specified.
204 >
205 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
206 >    the FBLIB environment variable. If you do not want to permit this then you
207 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
208 >    this setting.

316  
317 < 20. Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
317 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
318      stubs. Pedantic fix really, as procedures output in dependency order anyway.
319  
320 < 21. TIBExtact: Package Headers and Package Bodies are now included in the extracted
320 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
321      DDL (Firebird 3 and later only).
322  
323   22. TIBLookupComboBox Autocomplete Fixes:
# Line 114 | Line 328 | packages.
328          before autocomplete performed. i.e. behaviour now the same as when
329          no DataSource assigned.
330  
331 < 23. Single Line Comments starting with '--' are now ignored when occurring
331 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
332      between SQL statements.
333  
334   24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
# Line 126 | Line 340 | packages.
340      If true then the ObjectName is used as is without modification and matched
341      against the metadata object name. No attempt is made to remove double quotes.
342  
343 + 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
344 +    with eoTrigger, these extract types can be used to select only Database Triggers,
345 +    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
346 +
347 + 26. TIBXScript: If an exception occurs during the processing of a statement, the
348 +    statement separate character is now reset to the default (';').
349 +
350 + 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
351 +
352 + 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
353 +    a commit or reconnect statement and instead activated only when next SQL statement
354 +    is executed.
355 +

357 +
358 + 30. TIBXScript: case insensitive regex now used when matching statements instead of
359 +    converting statement to upper case.
360 +
361 + 31. TIBExtract: metadata comments now supported. New published property
362 +    IncludeMetaDataComments (default true). If true then metadata comments included

365 +
366 + 32. TIBExtract: ListObjectNames method added.
367 +
368 + 33. Updated Database component editor to support additional connection string
369 +    types.
