FBINTF Change Log version (1.4-2 Build 15853) Fri, 12 Jul 2024 13:41:21 +0100 1. IBUtils.FormatTimeZoneOffset A zero offset now includes a preceding '+' sign. 2. TFBStatement.DoJournaling now exits immediately if journaling is not active. The motivation for this is to avoid calling the Firebird API function 'getInfo' unnecesarily. This function can return an error if an incompatible parameter type was applied to the statement and hence can confuse resolving the bug. Note: a specific case is in (e.g.) OpenCursorAtStart method when the array of const includes a TDateTime. In this case, the param is set to a floating point type rather than a Firebird datetime (array of const loses the distinction). 3. TFBAttachment.SetParameters. if an attempt is made to set a parameter with a float value, the metadata type is checked to see if the parameter is a Date/Time type. If so then the value is assumed to be a TDateTime and the parameter is set using the AsDateTime property. Otherwise, the value is assumed to be a floating point type and the AsDouble property is used to set the property. This avoids the specific example given above. 4. IBHeader (legacy interface only) Definition of Start_Transaction changed to use varargs - win64 compatibility issue. 5. FB25Blob: last parameter of call to isc_blob_lookup_desc is now set to nil. This avoids memory corruption with Firebird 4 when using the legacy interface. 6. ISDL interface moved from FB30Array to IB. This is to avoid internal FPC compiler errors consequential on the use of generics across units. 7. Internal changes necessary to correctly compile and run with FPC 3.3.1 and later. 8. Firebird 5 support tested. 9. Firebird.pas renamed to FirebirdOOAPI.pas in order to avoid confusion with version distributed with Firebird. FBINTF Change Log version (1.4-1 Build 14103) Mon, 27 Nov 2023 14:26:35 +0000 1. FBSQLData: ensure that TResults.getSQLData and TResults.GetData use same error checks for range checking. 2. FB25Client: In GetIBMessage, fb_interpret is now called multiple times such that any additional error information is decoded. 3. FB25Statement: When changing a param type from Blob sub_type 1 to SQL_TEXT or SQL_VARYING charsetid is now preserved and size is set to default blob size. Now aligns with FB3 and later. 4. DDL and DML string literals are now explicitly set to the connection character set rather than the default character set provided by the compiler. 5. General tidy up of transliteration functions, now centralised in IBUtils. FPC testing now makes use of the RTL fpwidestring unit for support of international character sets. 6. Database exception handling (see section 9.3 in user guide). * For FB3 and later API: Connection Character set now applied to message returned by fb_interpret and message then transliterated if necessary to the system character set. * For Legacy API: The message character set is guessed as UTF8 unless invalid UTF8 characters found when connection character set is assumed. Message then transliterated if necessary to system character set. Note: this difference of behaviour is because legacy API presents exception messages "as is", while FB3 server attempts to transliterate to connection character set. FBINTF Change Log version (1.4-0 Build 14011) Sat, 05 Aug 2023 11:09:09 +0100 1. Support package fbudr added for support of User Defined Routines (UDRs), and package fbudrtestbed for client side debugging of UDR libraries. 2. Package layout changed with introduction of udr support. IB*.pas files moved from root directory to "client". IBHeader moved to "Client". 3. Delphi packages: all packages now compile .dcp and .bpi files to either fbintf\Win32\Debug or fbintf\Win64\Debug by default. Please remove any pre-existing fbintf.dcp and fbintf.bpi files from other locations. 4. Client side journaling support added. Interface changes IAttachment function JournalingActive: boolean; function GetJournalOptions: TJournalOptions; function StartJournaling(aJournalLogFile: AnsiString): integer; overload; function StartJournaling(aJournalLogFile: AnsiString; Options: TJournalOptions): integer; overload; function StartJournaling(S: TStream; Options: TJournalOptions): integer; overload; procedure StopJournaling(RetainJournal: boolean); 5. Transactions may now be given a local transaction name: IFirebirdAPI function StartTransaction(Attachments: array of IAttachment; TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload; TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit; aName: AnsiString=''): ITransaction; overload; function StartTransaction(Attachments: array of IAttachment; TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload; TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit; aName: AnsiString=''): ITransaction; overload; IAttachment function StartTransaction(TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload; function StartTransaction(TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload; function StartTransaction(TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit; aName: AnsiString=''): ITransaction; overload; function StartTransaction(TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit; aName: AnsiString=''): ITransaction; overload; ITransaction function GetTransactionName: AnsiString; procedure SetTransactionName(aValue: AnsiString); 6. Additional Transaction information ITPB.function AsText: AnsiString; {Returns TPB as a text string} ITransaction function GetDefaultCompletion: TTransactionCompletion; function GetJournalingActive(attachment: IAttachment): boolean; {attachment must be specified when multi-database transaction} 7. New IAttachment helper functions function HasTable(aTableName: AnsiString): boolean; function HasFunction(aFunctionName: AnsiString): boolean; function HasProcedure(aProcName: AnsiString): boolean; function GetAttachmentID: integer; function GetCharSetID: integer; 8. IStatement: if the BatchRowLimit is set to maxint, the maximum possible buffer size will be allocated for batch operations. 9. IStatement, IColumnMetaData and ISQLParam all now consistently provide: function GetStatement: IStatement; function GetTransaction: ITransaction; function GetAttachment: IAttachment; 10. Internal: a more disciplined approach to the handling of Firebird.IReferenceCounted interfaces. 11. New interface type: IFBNumeric. IFBNumeric is implemented in the unit FBNumeric and concentrates all handling of Fixed Point numbers. New ISQLItem and ISQLParam functions getAsNumeric and setAsNumeric allow for direct retrival and manipulation of numerics without loss of precision. 12. TryStrToNumeric and NumericToDouble moved from IBUtils to FBNumeric. 13. ISQLParams new method "Clear" 14. Connection Info (e.g. ODS Version, Remote Protocol) now retrieved on first request rather than on attachment connect. 15. IStatus.IBDataBaseErrorMessages now defaults to [ShowIBMessage]. This reflects the fact that SQLCodes are soon to be deprecated. In the future, the other options will be silently ignored if SQLCode support is not present in the Firebird Client library. 16. ITransaction changes Rollback and Commit from procedures to functions: function Commit(Force: boolean=false): TTrCompletionState; function Rollback(Force: boolean=false): TTrCompletionState; Specifically, this is to allow the functions to report back a failed commit or rollback when Force = true. In the case, the transaction handle has been released, while the transaction remains in limbo. 17. IAttachment ExecImmediate. When the transaction parameters are provided as an array of const and the statement fails, the transaction is rolledback (forced) before the exception is raised. 18. In Firebird 3 and later API: the status vector is now a thread var, as was already the case with the legacy API. Avoids problems when calling underlying Firebird API in multiple threads. 19. IBUtils: TSQLXMLReader: "string" type changed to "AnsiString" for compatibility reasons. 20. IDBInformation.DecodeVersionString now supported isc_info_firebird_version. 21. TSQLXMLReader: handle 'blob' as a reserved word 22. ISQLParam.SetAsVariant now accepts a vartype of varUString (UnicodeString). FBINTF Change Log version (1.3-3 Build 12935) Mon, 06 Dec 2021 23:17:13 +0000 1. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit. 2. Remove constraint in IAttachment.HasScollableCursors that returned false when using remote protocol. Scrollable cursors with remote database expected to be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return a not supported error. 3. IStatement: new function; TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable); TStatementFlags = set of TStatementFlag; function GetFlags: TStatementFlags; 4. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards compatibility. In Firebird 5, Update..Returning may returns multiple rows and hence the statemen type changes from ExecProcedure to Select. So that ExecuteQuery can continue to be used with Update...Retruning statements that return a singleton row, instead of raising an exception when ExecuteQuery is used with a (SELECT) statement, it will open the cursor and return the first row only. 5. ITransaction: new functions: function GetIsReadOnly: boolean; function GetTransactionID: integer; function GetTrInformation(Requests: array of byte): ITrInformation; overload; function GetTrInformation(Request: byte): ITrInformation; overload; The latter two return the Transaction Information block. The first two extract information the Transaction Information block 6. New function TSQLTokeniser.ReadCharacters Used internally. 7. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains parameter placeholders instead of named parameters. 8. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying transaction handle is now ignored if Rollback/Commit is called with Force=true 9. Tidy up of exception handling code. Under the legacy API, fb_interpret is now used to get an IBError Message instead of isc_interprete. 10. Internal tidyup. Native code now used for decoding integers and the events buffer. Avoids dependencies on fbclient functions isc_portable_integer, isc_event_block and isc_event_counts. 11. New IAttachment function function GetAttachmentID: integer; 12. Internal changes to TFBClientAPI, TFBAttachment and TFBTransaction and TFB30 subclasses to enable UDR support. FBINTF Change Log version (1.3-2 Build 12889) Sun, 24 Oct 2021 13:49:28 +0100 1. TFBClientAPI.GetProcAddr. Add check for nil reference. 2. IStatement: new methods: procedure SetStaleReferenceChecks(Enable:boolean); {default true} function GetStaleReferenceChecks: boolean; In previous versions, stale reference checks were always enabled. This allows the user to disable them on a per statement basis. Note this can risk out-of-date statement BLR. See User Guide. 3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a stored procedure and hence avoids replacing named parameters within a containing BEGIN..END block. 4. ISQLParam: using a string value to set an integer field with a scale factor of zero is now treated as a special case to avoid the risk of floating point rounding errors affecting pure integers. 5. ISQLParam: Review and tidy-up of SetAsString for numeric types. 6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable SQL Parameter metadata (methods moved from ISQLParam). 7. ISQLParam: new method function getColMetadata: IParamMetaData; This instance of IParamMetaData returns the original column metadata which is unmutable. Note: ISQLParam metadata can change after a parameter value has been set e.g when setting a VARCHAR column to an integer value. 8. IStatement: can now set cursor name when opening a cursor. New overloaded method: procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload; also IAttachment: function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload; function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload; function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; GenerateParamNames: boolean=false; CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload; function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString; GenerateParamNames: boolean=false; CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload; 9. Support for scrollable cursors added. New/updated methods: IAttachment: function HasScollableCursors: boolean; function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean=false): IResultSet; overload; function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload; function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean; params: array of const): IResultSet; overload; function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false; params: array of const): IResultSet; overload; function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean; params: array of const): IResultSet; overload; function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean=false): IResultSet; overload; function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload; function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean; params: array of const): IResultSet; overload; function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload; function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean; params: array of const): IResultSet; overload; IStatement: function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload; IResultSet: function FetchPrior: boolean; {fetch previous record} function FetchFirst:boolean; {fetch first record} function FetchLast: boolean; {fetch last record} function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set} function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current} function IsBof: boolean; 10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers. 11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This may be noticeable when a line separator occurs inside quoted text. The quoted text output by the tokeniser will now use the platform specific lineEnding regardless of whether the input uses the CRLF or LF as a line separator. 12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only) FBINTF Change Log version (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers. 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method will now be encoded inline (i.e. as part of the parameter buffer) if they are shorter than a pre-set limit. Longer values continue to be saved as blobs as a separate server interaction. This is intended as a performance optimisation. The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new IAttachment interface functions: function GetInlineBlobLimit: integer; procedure SetInlineBlobLimit(limit: integer); 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API user as the functionality is embedded in the implementation of the IStatement interface. Three new functions are defined: procedure AddToBatch; function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion; procedure CancelBatch; function GetBatchCompletion: IBatchCompletion; function GetBatchRowLimit: integer; procedure SetBatchRowLimit(aLimit: integer); Also function IsInBatchMode: boolean; {true after call to execute(eaDefer)} function HasBatchMode: boolean; {true if and only if IBatch Supported} For more information see the User Guide. 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages provided with the EIBInterBaseError now include all three parts. 5. Firebird.pas and include files updated to Firebird 4.0.0 6. New IStatement method: function GetSQLStatementTypeName: AnsiString; Returns SQL Statement type as a text string; 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger. FBINTF Change Log version (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a typo in FB30Statement.pas that caused an unknown parameter error. FBINTF Change Log version (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000 1. Imported (Firebird) constants updated for Firebird 4. 2. Firebird.pas from Firebird 4 integrated into source code tree. 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types. 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision. 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider. QueryInterface may be used to coerce this interface from IFirebirdAPI. The interface provides a single method "function GetIMasterIntf: IMaster". This provides type safe access to the Firebird IMaster interface and avoids the need to turn off object checks when coercing "function GetIMaster: TObject" to IMaster. 6. New IFirebirdAPI Calls: function HasLocalTZDB: boolean; function HasTimeZoneSupport: boolean; function HasExtendedTZSupport: boolean; procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte); function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD; 7. New IAttachment Calls: function HasDecFloatSupport: boolean; function GetTimeZoneServices: ITimeZoneServices; function HasTimeZoneSupport: boolean; 8. New Interface ITimeZoneServices. 9. New ISQLData API Calls: procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload; procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload; procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload; procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload; function GetAsUTCDateTime: TDateTime; function GetAsBCD: tBCD; 10. New ISQLParam API Calls procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload; procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload; procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload; procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload; function GetAsUTCDateTime: TDateTime; function GetAsBCD: tBCD; function GetStatement: IStatement; function GetTransaction: ITransaction; procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload; procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload; procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload; procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload; procedure SetAsUTCDateTime(aUTCTime: TDateTime); procedure SetAsBcd(aValue: tBCD); 11. New IArray API Calls procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload; procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload; procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload; procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload; function GetAsUTCDateTime(index: array of integer): TDateTime; procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload; procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZone: AnsiString); overload; procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload; procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload; 12. Utility functions in IBUtils function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime; var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean; procedure FBDecodeTime(aTime: TDateTime; var Hour, Minute, Second: word; var DeciMillisecond: cardinal); function FBEncodeTime(Hour, Minute, Second, DeciMillisecond: cardinal): TDateTime; function FBFormatDateTime(fmt: AnsiString; aDateTime: TDateTime): AnsiString; function FormatTimeZoneOffset(EffectiveTimeOffsetMins: integer): AnsiString; function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean; 13. IDPB, ITPB and ISPB: new interface method function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem; This is used to add a parameter block item by the string equivalent of its symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...' 14. IDPBItem/ITPBItem/ISPBItem: new interface method: function getParamTypeName: AnsiString; 15. fb_shutdown now called before unloading Firebird library. This can avoid a SIGEVENT error when a programme using the embeded server is unloaded. FBINTF Change Log version (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API with a Firebrid 3 client library. 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. 3. IUtil.FormatStatus now used to format error messages when using new API 4. Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer. 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. 6. New IFirebirdAPI Calls: function GetClientMajor: integer; function GetClientMinor: integer; 7. IColumnMetaData and IArrayMetaData: new method function GetCharSetWidth: integer; FBINTF Change Log version (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are case sensitive 2. Single line SQL comments starting with '--' are now recognised by SQL Parser. 3. New API Calls: IColumnMetaData.GetStatement IColumnMetaData.GetTransaction ISQLData.GetStrDataLength IResults.GetStatement IAttachment.OpenBlob (using Blob metadata) IAttachment.OpenArray (using array metadata) 4. FBMessages: removal of unused messages 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set. 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration. FBINTF Change Log version (1.1-4 Build 11515) Fri, 28 Dec 2018 10:04:19 +0000 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. 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. 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. 4. IColumnMetaData: new method. TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP} dfDateTime, {SQL DATETIME} dfTime); 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.
