Re: Composite Types and Function Parameters

Hello

I am thinking, so it isn't possible. There are a general datatype
anyelement, but it cannot accept a second general type record.

CREATE TYPE p AS (a text, b int, c bool);

CREATE OR REPLACE FUNCTION fp(p)
RETURNS int AS $$
BEGIN RAISE NOTICE 'a = %', $1.a; RETURN $1.b;
END;
$$ LANGUAGE plpgsql;

postgres=# select fp(row('hello',10, false));
NOTICE: a = hello
fp
────
10
(1 row)

Regards

postgres=# select fp(row('hello',10, false));
