PSQL

Type

INTEGER

In a “WHEN …​ DO” error handling block, the SQLCODE context variable contains the current SQL error code. Prior to Firebird 2.0, was only set in WHEN SQLCODE and WHEN ANY handlers. Now it may also be non-zero in WHEN GDSCODE and WHEN EXCEPTION blocks, provided that the condition raising the error corresponds with an SQL error code. Outside error handlers, is always 0. Outside PSQL, it doesn’t exist at all.
