# Line 1 | Line 1
1 + IBX Change Log  version (2.3-5 Build 12212) Fri, 17 Jul 2020 15:24:08 +0100
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.
41 +
42 + IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
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.
209 +
210 + IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
211 +
212 + 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
213 +   Utf8EscapeControlChars
214 +
