Just a guy fiddling with computers. I don't have a Delphi or formal programming background... but Lazarus/FreePascal really works for me!

Database test framework run
Ran database test framework for FPC trunk on 25 September 2012.
Remarks on some TTestFieldTypes tests:
- TTestFieldTypes.TestInsertLargeStrFields tries to create a 16000 character field; UTF8 encoded Firebird dbs only support up to about 8000 characters (32768 bytes). So the same problem as the UTF8 field length issue.
- TTestFieldTypes.TestCrossStringDateParam: exception invalid variant type cast=>conversion error or something? would require stepping through the code to find out what's wrong I suppose
- TTestFieldTypes.TestTemporaryTable: fixed test; Firebird supports temp tables
- TTestFieldTypes.TestLargeRecordSize: fields are 8192 chars; same issue as TTestFieldTypes.TestInsertLargeStrFields
todo: do the rest
Sybase with FPC trunk => fix this:
CREATE TABLE FPDEV_FIELD (ID INT NOT NULL,FString VARCHAR(10),FSmallint SMALLINT,FInteger INTEGER,FBoolean BIT,FFloat FLOAT,FCurrency MONEY,FBCD DECIMAL(18,4),FDate DATETIME,FDateTime DATETIME,FBytes BINARY(5),FVarBytes VARBINARY(10),FBlob IMAGE,FMemo TEXT,FFixedChar CHAR(10),FWideString NVARCHAR(10),FLargeint BIGINT,FTimeStamp TIMESTAMP,FFMTBcd NUMERIC(18,6),FFixedWideChar NCHAR(10),PRIMARY KEY (ID)).........a.. ....O.COLUMN OR parameter #5: -- can't specify Null values on a column of type BIT. .SYBASE..../.. ......Can't find type 'TIMESTAMP'.
dsMaxStringSize (e.g. in fields.inc) indicates maximum (string field)? size that an internal buffer provides. If a field is larger, a temporary buffer will need to be used.
Firebird 3 API
See http://sourceforge.net/p/uib/code/HEAD/tree/trunk/source/uibfblib.pas Probably only usable on Windows and by accident as C++ is used not C. See discussion on firebird development list by Tony Whyman.
TSQLScript parameter bug
Still present in 2.6.4; fixed 2.7.1.
TSQLScript Firebird script bugs
Running CREATE scripts for stored procedures fails even with set term enabled as TSQLScript chops up the script. Issue #26137
Probably easiest to reuse work of http://www.jcolibri.com/articles/bdd/interbase/sql_script_executer/sql_script_executer.htm and the SQL parser in SQLDB to properly parse the script and run it.
Still issues in current trunk; setting CommentsInSQL to false works around bug when creating stored procs/triggers with comments inside them, see Issue #26571
Errors compiling re _fini and _init
On Linux, errors like this when linking:
cprt0.o: In function `_haltproc_eabi': (.text+0x88): undefined reference to `_fini' cprt0.o: In function `_haltproc_eabi': (.text+0x90): undefined reference to `_init
... can be addressed by installing build-essential package see Issue #24056
Should this go on the wiki somewhere...? But where? Occasional reports on the forum about this..
- Gdb 7.3.50 appears broken for i386 running with Lazarus since about 1.1; get invalid application or something when running under debugger. 7.2 (as distributed with current installers) does seem to work.
Perhaps worth having a look:
- Firebird 3 driver (split out from ib)
- DB performance/stress testing
- Visual SQL Query designer => https://bitbucket.org/reiniero/lazopenqbuilder/overview
