`GDSCODE`

Firebird error code of the error in a WHEN … DO block

Available in

PSQL

Type

INTEGER

Syntax

GDSCODE

In a “WHEN … DO” error handling block, the GDSCODE context variable contains the numeric value of the current Firebird error code.GDSCODE is non-zero in WHEN … DO blocks, if the current error has a Firebird error code.Outside error handlers, GDSCODE is always 0.Outside PSQL, it doesn’t exist at all.

Note	After `WHEN GDSCODE`, you must use symbolic names like `grant_obj_notfound` etc.But the `GDSCODE` context variable is an `INTEGER`.If you want to compare it against a specific error, the numeric value must be used, e.g.`335544551` for `grant_obj_notfound`.

Example

when gdscode grant_obj_notfound, gdscode grant_fld_notfound,
   gdscode grant_nopriv, gdscode grant_nopriv_on_base
do
begin
  execute procedure log_grant_error(gdscode);
  exit;
end
