Re: can't call function to delete the table

Hello Pepe,

RETURN NEW; is a statement only for functions which are declared with
RETURNS TRIGGER and are used by triggers.

Even then no statement after the RETURN NEW; would ever be executed, so
it remains unclear what v_Ret := SQLSTATE; i is supposed to do.

Regards,

Holger
