hello,
i have a procedure and a trigger as below
______________________________________________________________________
create function FUNCTEST () returns opaque
as
'begin
delete from X where COLX in (select COLX from X
where COLX not in (select COLY from Y ));
return null;
end;'
language 'plpgsql';
create trigger TRIGTEST after delete on Y for each row
execute procedure FUNCTEST();
________________________________________________________________________
i need some tuples to be deleted from X while i delete some from Y.
the function and trigger are created without any problem.
when i delete a tuple from Y , i get the following error.
