Re: returning rows from a function

You can't return a result set as such from a function. But if you are using
7.2, you can now return a cursor to a result set:

Subject: [GENERAL] returning rows from a function

I am new to Postgres and have a rather straightforward question. Is it
possible, and if so, what is the syntax for returning a recordset from a
function?

I have tried

CREATE FUNCTION selectUserProperties(text) RETURNS RECORD

and

CREATE FUNCTION selectUserProperties(text) RETURNS SETOF varchar

Neither of which seems to work. The rest of the function is.

CREATE FUNCTION selectUserProperties (text) RETURNS RECORD
AS '

BEGIN
SELECT key,
value
FROM user_properties
WHERE username = $1;

END;

' LANGUAGE 'plpgsql';

Both key and value in this example are varchar columns.

Thanks for your help.
