9.17. SQLCODE
Available inPSQL
Deprecated in2.5.1
TypeINTEGER
DescriptionIn a
error handling block, the WHEN … DOSQLCODE 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.
Example
when any
do
begin
if (sqlcode <> 0) then
Msg = 'An SQL error occurred!';
else
Msg = 'Something bad happened!';
exception ex_custom Msg;
end
SQLCODE is now deprecated in favour of the SQL-2003-compliant Section 9.18, “SQLSTATE” status code.
Support for SQLCODE and WHEN SQLCODE will be discontinued in some future version of Firebird.
