SQLCODE

`SQLCODE`

Tip

Find a more recent version at Firebird 5.0 Language Reference: SQLCODE

Available in: PSQL

Added in: 1.5

Changed in: 2.0

Description: In a “WHEN ... DO” error handling block, the SQLCODE context variable contains the current SQL error code. Prior to Firebird 2.0, SQLCODE 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, SQLCODE is always 0. Outside PSQL it doesn't exist at all.

Type: INTEGER

Example:

when any
do
begin
  if (sqlcode <> 0) then
    Msg = 'An SQL error occurred!';
  else
    Msg = 'Something bad happened!';
  exception ex_custom Msg;
end
