Re: Stored Procedure Question

I am using 8.1. Now I am trying to create my function that returns multiple
columns. I have added an OUT parameter, but of what type must it be?

Any type I try to return it tells me that only one column can be returned.

Here is my function...

CREATE OR REPLACE FUNCTION "public"."sp_getcontacts" (out myrecord varchar)
RETURNS varchar AS
$body$
select firstname, lastname from contacts
$body$
LANGUAGE 'sql' VOLATILE CALLED ON NULL INPUT SECURITY INVOKER;

In 8.1 you can use OUT or INOUT parameters; in earlier versions you
can create a custom type or use "record".  If you return "record"
then you'll need to provide a column list when you call the function.
