Thread: Problem with returning setof record

Hello,

Here is a simple function I created for a test.

create function ttt() returns setof record as '
declare
r record;
begin
for r in select * from utilisateurs.menus loop  return next r;
end loop;
return;
end;
' language 'plpgsql';

When I try to use it, it returns to me :

select ttt();set-valued function called in context that cannot accept a set
:  PL/pgSQL function "ttt" line 5 at return next

Anyone has an idea ?

Best regards,
Patrice OLIVER

You need to treat it like a table:  SELECT * FROM ttt();
Also, I'm not sure you can return a setof anonymous record types (unless 
you can specify the structure in the select).
Try CREATE FUNCTION...RETURNS SETOF utilisateurs.menus

If there's no appropriate table you can use CREATE TYPE to create a 
structure.
