[fpc-pascal] Decimal Precision Issue with Firebird

[Andrew Hall]

We are having problems reading decimal/numeric column types with TSQLQuery. It appears if the precision of a decimal/numeric is more than 4 (for instance, DECIMAL(12,8) or DECIMAL(18,10) or DECIMAL(10,6) TSQLQuery raises an exception on reading - EDatabaseError : Unknown field type : COLUMN_NAME. However, using the established (informal) money-types for Firebird - DECIMAL(18,4) or DECIMAL(10,4) are OK, and multiple other variations are OK if precision is 4 or less.

Questions:



Thank you.
Regards,
Andrew Hall.

[Using Firebird 211 with FPC 224 on MacOSX 10.5 with XCode 311]

1) is this a bug, or a known "feature" or limitation of the FPC Firebird library? 2) is there a workaround? We require a decimal with at least 9 decimal places precision (?perhaps DOUBLE PRECISION) 3) the issue with negative numerics with TSQLQuery being treated as unsigned, described in the bug list as fixed in FPC 231 - has this fix been moved to FPC 224?
