Thread: Question on returning Rows in a stored proc

Hi,

I'm new to pl/pgsql and while exploring the world of writing stored procs, I came up with a question that I hope some kind person can help me with, namely, how does one return a bunch of rows?
From the examples that I've found on the web, I can return and integer, a real, etc.  But if I wanted to return the results of something like a query, (e.g. SELECT * FROM foo), how would I do that?

Create your function as "... returns setof ... ", read more:

Look in the docs for set returning functions.
