TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change. +1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API + with a Firebrid 3 client library. -IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000 +2. Linux Only: FIREBIRD environment variable is now checked when loading the client library. + If a client library path is not explicitly provided and the FIREBIRD environment + variable is set then the directory given by this variable and any 'lib' subdirectory + are searched for the Firebird client library. Only if none is found, is the default + client library used. -1. In a TIBCustomDataset descendent, a generator now only sets the value when - it is null. This allows for alternative user defined setting of the generator +3. IUtil.FormatStatus now used to format error messages when using new API - Many thanks to Julio Jiménez for this fix +4. Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer. -2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library - and suggests that the user may have forgotten to install it. +5. SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is + returned using GetAsString and the string codepage is UTF8, the string is truncated so + that the byte length corresponds to the number of characters specified for the column. + SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is + correct behaviour but may affect some implementations that relied upon automatic + trimming of trailing white space. -IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000 +6. New IFirebirdAPI Calls: + function GetClientMajor: integer; + function GetClientMinor: integer; -1. Conditional compilation used to limit registration of TIntegerField to - Lazarus versions less than 1.1 -2. When a database connection is created, character set is now by default set - to UTF8 (Unix) or to the current Windows code page (Windows) if in the range - 1250 to 1254. +FBINTF Change Log version (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100 +1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are + case sensitive -IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100 +2. Single line SQL comments starting with '--' are now recognised by SQL Parser. -1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change. +3. New API Calls: + IColumnMetaData.GetStatement + IColumnMetaData.GetTransaction + ISQLData.GetStrLength + IResults.GetStatement + IAttachment.OpenBlob (using Blob metadata) + IAttachment.OpenArray (using array metadata) +4. FBMessages: removal of unused messages -IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100 +5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set. -1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0 - Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1 +6. TIBSQLStatementType: SQLSavePoint added to end of enumeration. -2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB - package is changed to do this (which it should do). +FBINTF Change Log version (1.1-4 Build 11515) Fri, 28 Dec 2018 10:04:19 +0000 -IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100 +1. Fix a problem with the SQL parameter parser that failed to recognise parameters + where the second character of the parameter name is a numeric. -1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close). +2. New method for IAttachment: procedure getFBVersion(version: TStrings); + This returns the isc_version connection information as one or more lines. + This is the same information as returned by isql with the -z option. -2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance) +3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API + is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a + compiler option then the Firebird 3 API is no longer compiled in. -3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes +4. IColumnMetaData: new method. -4. Property editors should now correctly resize. + TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP} + dfDateTime, {SQL DATETIME} + dfTime); -5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox - (restored original functionality) + function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer; + + This returns the max. number of characters returned by the "AsString" method + when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME. + +5. Additional argument for IAttachment.PrepareWithNamedParameters - + CaseSensitiveParams: boolean = false + + If this argument is set to true then SQL parameter names are assumed to be case + sensitive and must be referenced (using ISQLParams.ByName) using the case + sensitive name. + +6. Bug fix: when setting a query parameter, it is now possible, when the parameter + is of type VarChar or Char to set the parameter to a numeric value (e.g. using + .AsCurrency) and then subsequently to update the value to a non-numeric string + using .AsString. + + + +FBINTF Change Log version (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000 + +1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary + +2. Restrict IsMultiThread check to Unix only for compatibility with + https://bugs.freepascal.org/view.php?id=30535 + +3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with + named parameters and is intended to avoid problems with (e.g.) Execute Block + and processing internal parameters as statement parameters. + +4. New interface IFirebirdLibrary provides access to the underlying firebird DLL + or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI. + +5. New function added to IB.pas + + function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary + + This allows a Firebird Library to be loaded from an explicit path. use the + IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using + the library. It is possible to load Firebird libraries from different locations + simultaneously, each with a distinct IFirebirdAPI. + +FBINTF Change Log version (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100 + +1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when + program compiled with -CR command line switch. + +2. IServiceManager additions (informational): + function getProtocol: TProtocol; + function getPortNo: AnsiString; + +3. IServiceManager improved error handling. Interfaces changed: + function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean; + function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload; + function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload; + +4. IAttachment addition (informational) + function GetSecurityDatabase: AnsiString; + +5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics + thus now returns accumulated stats for a select statement from opening a cursor + up to the last fetch. + +6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting + the problem. + +7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64" + replaces deprecated "comp" type. + +10. Testsuite Test10 updated to include thread synchronisation for event reporting. + +11. URL Connection Strings: inet4 and inet6 now recognised. + +12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax. + +13. IAttachment.CharSetName2CharSetID is now performed case insensitive. + + +FBINTF Change Log version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000 + +1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character. + +2. IAttachment: add two new methods + function HasDefaultCharSet: boolean; + function GetDefaultCharSetID: integer; + + These return, respectively, true if a connection default character set was + specified and the character set id of the connection default character set. + The DefaultCharSetID is cached when the connection is opened and hence does not + require a database lookup. + +3. Avoid exception when a text blob is a stored procedure parameter. + +4. Update test suite to include a test for a stored proc returning a text blob. + +5. IAttachment: add + function GetRemoteProtocol: AnsiString; + function GetODSMajorVersion: integer; + function GetODSMinorVersion: integer; + function GetAuthenticationMethod: AnsiString; + + These results are cached when the connection is opened and hence do not + require a database lookup. + +6. IAttachment: add "function GetConnectString: AnsiString;" This returns the + connect string used to create/connect to the database. + +7. IAttachment: Create Database using SQL statement. The username and password + are now extracted and used to populate a DPB made available via IAttachment.getDPB. + It is now possible to use IAttachment disconnect/connect to reconnect to + a database for which the initial connection was established by a create + database sql statement. Available in FPC only. + +8. Update Test 1 to test 5, 6 and 7 above. + +9. IBUtils code tidy up. + +10. Parameter Block interfaces "find" method. As documented, this should have + returned a nil interface when the item could not be found. Instead, an empty + interface item was returned. "Find" now works as documented and will return + a nil interface if the item cannot be found. + +11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date. + +12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information + requests with additional parameters. This is to enable support for fb_info_page_contents + (return of page contents). Response to fb_info_page_contents returned as + a string with code page CP_NONE. + +13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus + test suite updated. + +14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as + a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type. + +15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet. + An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non + default connection port to be specified. + +FBINTF Change Log version (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000 + +1. Fix issues with setting SQL Param values using SetAsString with Numeric types. + Scale is no longer ignored. + +2. Fix issues with setting SQL Param values using SetAsString with Date values + not in locale format but which are recognised by Firebird. Date values that + cannot be converted to a string using Pascal library are now passed through + to Firebird as Text Strings. + +3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns + UTF8 and not UNICODE_FSS. + +4. Charset ID problem. When using Firebird 3, with no default database character set + and a column has a non-default collation specified, an incorrect character set + id was being reported that could result in a 'division by zero' error when + used by IBX. This has now been fixed. + +5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID, + CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as + the character sets supported can be updated on a per database basis. That is + it is possible to add a (Firebird) user defined character set to a database. + +6. Add RegisterCharSet to IAttachment. This is used to register a user defined character + set supported by Firebird with the API. + +7. Add missing isc_info_db_read_only to list of decoded Database Information items + in FBOutputBlock.pas and update test suite to include this item. + +8. FB30Client: avoid always using "StartMultiple" when only a single database attachment. + +9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client + library or finding it by disk location, the PATH environment variable is now also set to + include the FIREBIRD directory. This is to ensure that the correct dlls in the + firebird client library dependencies are loaded. + +10. Testsuite: Ensure consistent UTF-8 output on Windows console. + +11. Testsuite: Update Windows script to include FPC 3.0.4 in search path. + +12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer + +13. FB30Statement: A check has been added to ensure that all SQL Parameters + have been given a value (including NULL). Previously, failing to set the + value of an SQL Parameter could give rise to unpredictable results or + an SQLDA error. + +14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set. + +15. FBAttachment: Avoid string reference count error when processing an Ansistring + parameter in an array of const passed to IAttachment.OpenCursor, etc. + +16. FBAttachment: Allow for WideString and UnicodeString parameters in an array + of const passed to IAttachment.OpenCursor, etc. + + +FBINTF Change Log version (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000 + +1. Change syntax to Mode Delphi + +2. Change all uses of string type to explicit AnsiString in order to ensure + compatibility between Delphi and FPC. + +3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs + defined for each interface. + +4. Generics syntax variations for Delphi added + +5. PChar replaced with PByte expect where an actual string is being referenced, + where PAnsiChar is used instead. + +6. Review of type definitions in IBExternals to ensure Delphi compatibility + +7. Testsuite updated for Delphi + +FBINTF Change Log version (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000 + +1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with + large blobs and the FB3 API. + +2. Update Event Handling algorithm to avoid looping due to recreation of the + event block. + +3. Avoid invalid XSQLDA error when the only parameter is updated to null + +4. Array Handling: fix problem with text arrays with character set none. When the + DB connection has a default character set (e.g. UTF8), an error is raised by + Firebird if the space allocated is not enough to allow for transliteration, even + though it is not required for character set none. + +5. IBUtils: List of reserved words brought up-to-date + +6. Add ISQL style performance statistics collection to IStatement + +7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided + CREATE DATABASE statement. + +8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in + an array dimension is not mistaken for a named parameter prefix. + +9. Trim function no longer applied to result of GetAsString for SQL_TEXT + when Character set is octets. Avoids loss of non printable characters at start of string. + +10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance + statistics for the last action. Requires use of procedure IStatement.EnableStatistics + to enable stats gathering. + +11. API Version information added as constants to IB.pas + +12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID + +13. Firebird Character set "NONE" now interpreted as codepage CP_ACP. + +FBINTF Change Log version (1.0-0) Tue, 06 Dec 2016 10:33:47 +0000 + +1. Initial Release -6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird - library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
