2
3	<	1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
4	<	This is typically used during an "OnBeforeOpen" event handler to manipulate the
5	<	"Where" and "Having" clauses to implement user specified filters of arbitrary
6	<	complexity.
3	>	1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
4	>	case sensitive
5
6	<	2. A new Component Palette entry "Firebird Data Controls" is now available. This has
9	<	three new data aware controls dependent on IBX and which make use of the SQL Parser.
10	<	These are:
6	>	2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
7
8	<	- TIBLookupComboEditBox
9	<	- TIBDynamicGrid
10	<	- TIBTreeview
8	>	3. New API Calls:
9	>	IColumnMetaData.GetStatement
10	>	IColumnMetaData.GetTransaction
11	>	ISQLData.GetStrLength
12	>	IResults.GetStatement
13	>	IAttachment.OpenBlob (using Blob metadata)
14	>	IAttachment.OpenArray (using array metadata)
15
16	<	TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
17	<	of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
18	<	to revise the available list and restrict it to items that are prefixed by the
19	<	typed text (either case sensitive or case insenstive). Autoinsert allows a
20	<	newly typed entry to be added to the list dataset and included in the available
21	<	list items.
16	>	4. FBMessages: removal of unused messages
17
18	<	TIBDynamicGrid is a TDBGrid descendent that provides for:
24	<	- automatic resizing of selected columns to fill the available row length
25	<	- automatic positioning and sizing of a "totals" control, typically at the
26	<	column footer, on a per column basis.
27	<	- DataSet resorting on header row click, sorting the dataset by the selected column.
28	<	A second click on the same header cell reversed the sort order.
29	<	- Support for a "Panel Editor". That is on clicking the indicator column, the row
30	<	is automatically expanded and a panel superimposed on it. The panel can have any
31	<	number of child controls, typically data aware controls with the same datasource
32	<	as the grid allowing for editing of additional fields and more complex editors.
33	<	- Reselection of the same row following resorting.
34	<	- A new cell editor that provides the same functionality as TIBLookupComboEditBox.
35	<	Its properties are specified on a per column basis and allows for one or more
36	<	columns to have their values selected from a list provided by a dataset.
37	<	Autocomplete and autoinsert are also available. The existing picklist editor
38	<	is unaffected by the extension.
18	>	5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
19
20	<	TIBTreeView is a data aware TCustomTreeView.
20	>	6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
21
22	<	3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
43	<	zero scale will no longer return an error. An Int64 will be returned instead.
22	>	FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
23
24	<	4. TIBTransaction now has events for Before and After Transaction End and a new function
25	<	"GetEndAction" allowing the EndAction to be accessed by these event handlers.
24	>	1. Fix a problem with the SQL parameter parser that failed to recognise parameters
25	>	where the second character of the parameter name is a numeric.
26
27	<	5. TIBQuery can now handle correctly queries which contain the same keyword parameter
28	<	repeated multiple times.
27	>	2. New method for IAttachment: procedure getFBVersion(version: TStrings);
28	>	This returns the isc_version connection information as one or more lines.
29	>	This is the same information as returned by isql with the -z option.
30
31	<	6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
32	<	check used to get in the way of using Stored Procedures, and "Update or Insert"
33	<	statements.
31	>	3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
32	>	is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
33	>	compiler option then the Firebird 3 API is no longer compiled in.
34
35	<	7. Insert, Modify and Delete property Editors now support Query Generation from
56	<	Stored Procedures.
35	>	4. IColumnMetaData: new method.
36
37	<	8. Three new examples illustrate the use of the new IB Controls
37	>	TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
38	>	dfDateTime,   {SQL DATETIME}
39	>	dfTime);
40
41	+	function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;

43	<	IBX Change Log  version                      (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
43	>	This returns the max. number of characters returned by the "AsString" method
44	>	when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
45
46	<	1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
47	<	setting performance. See "readme.field+param.names in the doc folder.(Thanks to
65	<	Gabor Boros for reporting this problem and for testing the improvements).
46	>	5. Additional argument for IAttachment.PrepareWithNamedParameters -
47	>	CaseSensitiveParams: boolean = false
48
49	<	2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
50	<	See readme.field+param.names in the doc folder.
49	>	If this argument is set to true then SQL parameter names are assumed to be case
50	>	sensitive and must be referenced (using ISQLParams.ByName) using the case
51	>	sensitive name.
52
53	<	3. IBX SQL Editors will now automatically add double quotes around column names when the database
54	<	dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
53	>	6. Bug fix: when setting a query parameter, it is now possible, when the parameter
54	>	is of type VarChar or Char to set the parameter to a numeric value (e.g. using
55	>	.AsCurrency) and then subsequently to update the value to a non-numeric string
56	>	using .AsString.
57
73	–	4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
58
75	–	5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
76	–	actions.
59
60	<	6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
79	<	thanks to Yuriy Kopnin for pointing this out).
60	>	FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
61
62	<	7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
62	>	1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
63
64	<	8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
65	<	for both fields and parameter setting.
64	>	2. Restrict IsMultiThread check to Unix only for compatibility with
65	>	https://bugs.freepascal.org/view.php?id=30535
66
67	<	9. Changes to the Select SQL in an IBCustomDataset descendent should now be
68	<	visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
67	>	3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
68	>	named parameters and is intended to avoid problems with (e.g.) Execute Block
69	>	and processing internal parameters as statement parameters.
70
71	<	10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
72	<	when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
71	>	4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
72	>	or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
73
74	<	11. TIBTable now has a property editor for "MasterFields"
74	>	5. New function added to IB.pas
75
76	<	12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
95	<	GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
76	>	function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
77
78	<	13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
79	<	of settings is unrecognised. Selecting this radio button has no effect on the settings.
80	<
78	>	This allows a Firebird Library to be loaded from an explicit path. use the
79	>	IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
80	>	the library. It is possible to load Firebird libraries from different locations
81	>	simultaneously, each with a distinct IFirebirdAPI.

84
85	<	1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
85	>	1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
86	>	program compiled with -CR command line switch.

88	<	IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
88	>	2. IServiceManager additions (informational):
89	>	function getProtocol: TProtocol;
90	>	function getPortNo: AnsiString;
91
92	<	1. In a TIBCustomDataset descendent, a generator now only sets the value when
93	<	it is null. This allows for alternative user defined setting of the generator
92	>	3. IServiceManager improved error handling. Interfaces changed:
93	>	function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
94	>	function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
95	>	function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
96
97	<	Many thanks to Julio Jiménez for this fix
97	>	4. IAttachment addition (informational)
98	>	function GetSecurityDatabase: AnsiString;
99
100	<	2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
101	<	and suggests that the user may have forgotten to install it.
100	>	5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
101	>	thus now returns accumulated stats for a select statement from opening a cursor
102	>	up to the last fetch.
103
104	<	IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
104	>	6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
105	>	the problem.
106
107	<	1. Conditional compilation used to limit registration of TIntegerField to
108	<	Lazarus versions less than 1.1
107	>	7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
108	>	replaces deprecated "comp" type.
109
110	<	2. When a database connection is created, character set is now by default set
121	<	to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
122	<	1250 to 1254.
110	>	10. Testsuite Test10 updated to include thread synchronisation for event reporting.
111
112	+	11. URL Connection Strings: inet4 and inet6 now recognised.

120
121	<	1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
133	<	Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
121	>	1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
122
123	<	2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
124	<	package is changed to do this (which it should do).
123	>	2. IAttachment: add two new methods
124	>	function HasDefaultCharSet: boolean;
125	>	function GetDefaultCharSetID: integer;
126
127	<	IBX Change Log  version (1.0-0)  Sat, 28 Apr 2012 16:43:00 +0100
127	>	These return, respectively, true if a connection default character set was
128	>	specified and the character set id of the connection default character set.
129	>	The DefaultCharSetID is cached when the connection is opened and hence does not
130	>	require a database lookup.
131
132	<	1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
132	>	3. Avoid exception when a text blob is a stored procedure parameter.
133
134	<	2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
134	>	4. Update test suite to include a test for a stored proc returning a text blob.
135
136	<	3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
136	>	5. IAttachment: add
137	>	function GetRemoteProtocol: AnsiString;
138	>	function GetODSMajorVersion: integer;
139	>	function GetODSMinorVersion: integer;
140	>	function GetAuthenticationMethod: AnsiString;
141
142	<	4. Property editors should now correctly resize.
142	>	These results are cached when the connection is opened and hence do not
143	>	require a database lookup.
144
145	<	5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
146	<	(restored original functionality)
145	>	6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
146	>	connect string used to create/connect to the database.
147	>
148	>	7. IAttachment: Create Database using SQL statement. The username and password
149	>	are now extracted and used to populate a DPB made available via IAttachment.getDPB.
150	>	It is now possible to use IAttachment disconnect/connect to reconnect to
151	>	a database for which the initial connection was established by a create
152	>	database sql statement. Available in FPC only.
153	>
154	>	8. Update Test 1 to test 5, 6 and 7 above.
155	>
156	>	9. IBUtils code tidy up.
157	>
158	>	10. Parameter Block interfaces "find" method. As documented, this should have
159	>	returned a nil interface when the item could not be found. Instead, an empty
160	>	interface item was returned. "Find" now works as documented and will return
161	>	a nil interface if the item cannot be found.
162	>
163	>	11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
164	>
165	>	12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
166	>	requests with additional parameters. This is to enable support for fb_info_page_contents
167	>	(return of page contents). Response to fb_info_page_contents returned as
168	>	a string with code page CP_NONE.
169	>
170	>	13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
171	>	test suite updated.
172	>
173	>	14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
174	>	a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
175	>
176	>	15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
177	>	An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
178	>	default connection port to be specified.

182	>	1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
183	>	Scale is no longer ignored.
184	>
185	>	2. Fix issues with setting SQL Param values using SetAsString with Date values
186	>	not in locale format but which are recognised by Firebird. Date values that
187	>	cannot be converted to a string using Pascal library are now passed through
188	>	to Firebird as Text Strings.
189	>
190	>	3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
191	>	UTF8 and not UNICODE_FSS.
192	>
193	>	4. Charset ID problem. When using Firebird 3, with no default database character set
194	>	and a column has a non-default collation specified, an incorrect character set
195	>	id was being reported that could result in a 'division by zero' error when
196	>	used by IBX. This has now been fixed.
197	>
198	>	5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
199	>	CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
200	>	the character sets supported can be updated on a per database basis. That is
201	>	it is possible to add a (Firebird) user defined character set to a database.
202	>
203	>	6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
204	>	set supported by Firebird with the API.
205	>
206	>	7. Add missing isc_info_db_read_only to list of decoded Database Information items
207	>	in FBOutputBlock.pas and update test suite to include this item.
208	>
209	>	8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
210	>
211	>	9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
212	>	library or finding it by disk location, the PATH environment variable is now also set to
213	>	include the FIREBIRD directory. This is to ensure that the correct dlls in the
214	>	firebird client library dependencies are loaded.
215	>
216	>	10. Testsuite: Ensure consistent UTF-8 output on Windows console.
217	>
218	>	11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
219	>
220	>	12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
221	>
222	>	13. FB30Statement: A check has been added to ensure that all SQL Parameters
223	>	have been given a value (including NULL). Previously, failing to set the
224	>	value of an SQL Parameter could give rise to unpredictable results or
225	>	an SQLDA error.
226	>
227	>	14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
228	>
229	>	15. FBAttachment: Avoid string reference count error when processing an Ansistring
230	>	parameter in an array of const passed to IAttachment.OpenCursor, etc.
