hi, all:
When I see the following definitions from postgresql document. I am
completely puzzeled.
CREATE TABLE foo (fooid int, foosubid int, fooname text);
>> As I say it, foo is already a set of columns.
CREATE FUNCTION getfoo(int) RETURNS setof foo AS '
SELECT * FROM foo WHERE fooid = $1;
' LANGUAGE SQL;
>> here return type should be "setof setof foo".
----------------------------------------------------------------------------
-----------------
Can I rewrite the definition as follows:
CREATE TYPE foo (fooid int, foosubid int, fooname text);
CREATE FUNCTION getfoo(int) RETURNS setof foo AS '
SELECT * FROM foo WHERE fooid = $1;
' LANGUAGE SQL;
----------------------------------------------------------------------------
-------------------
any comments are appriciate.
