Re: PL/PgSQL - returning multiple columns ...

Hi Marc,

One option is to create a simple data type and return the rowtype of the
datatype

eg CREATE TYPE tserverload AS ("server_name" text, "load_avg" int4);

CREATE FUNCTION getserverload()

RETURNS tserverload

AS

'DECLARE

r tserverload%rowtype;

etc.

You would then return r, comprised of r.server_name and r.load_avg.
