Hi!
Currently it's possible to set TraceDSQL config parameter in dev build
to have formatted statement BLR in firebird.log, but that is not
sufficient for automated tests.
I want to add facility to make it possible to applications request
individual statements BLR for debug and test purposes (also in prod build).
Here is the design I would go:
interface Statement
{
const uint PREPARE_PRESERVE_BLR = 0x80;
}
#define isc_info_sql_blr_bytes 31
#define isc_info_sql_blr_text 32
Statements prepared with PREPARE_PRESERVE_BLR would be usable with
getInfo and isc_info_sql_blr_*.
isc_info_sql_blr_bytes retrieves raw BLR bytes and isc_info_sql_blr_text
retrieves formatted BLR as the BLOB filter/TraceDSQL.
ISQL will have SET BLR_DISPLAY OFF/ON/ONLY. ONLY will make only
prepare/display without execution.
ISQL would use isc_info_sql_blr_text and retrieves already formatted
data ready for display.
That would be for master and v4.
Comments?
