Обсуждение: ERROR: a column definition list is required for functions returning "record"

Hello

you have to specify column names and column types. Like


postgres=# create or replace function foog() returns setof record as $$
declare r record; begin r := row(10,20); return next r ; return; end;
$$ language plpgsql;

postgres=# select * from foog() t(a int, b int);  a  | b
----+----
 10 | 20
(1 row)
