Hi,
Is it possible to do the equivalent of RAISE EXCEPTION inside a C-function?
Like this:
PG_FUNCTION_INFO_V1(check_something);
Datum check_something(PG_FUNCTION_ARGS)
{
// RAISE EXCEPTION 'bla bla'
}
CREATE OR REPLACE FUNCTION do_check() RETURNS text AS $$
BEGIN
PERFORM check_something();
RETURN 'All good';
EXCEPTION
WHEN RAISE EXCEPTION THEN
RETURN 'Something bad';
END;
$$ LANGUAGE plpgsql IMMUTABLE;
That code may not work but you get the idea, I want to throw an exception from
a C function that can be caught in PL/pgSQL. Also is it further possible to
catch the message that RAISE EXCEPTION sends? Like 'Something bad: bla bla'
Thanks,
Elliot
