Problem returning a cursor through ODBC to ASP layer from postgres

I have created a function in postgres called getallusers(var) that returns a cursor. This works fine at the psql level but when I try to return it through ODBC I get errors.

The function is as follows:

CREATE OR REPLACE FUNCTION getallusers(refcursor) RETURN refcursor AS'

begin
open $1 for select * from users;
return $1;
end;
' language 'plpgsql';

I call it like this:

<%
strconn="DSN=p_test;uid=postgres;pwd="
mySQL = "begin "&vbcrlf
mySQL = mySQL & "select getallusers('rs'); "
mySQL = mySQL & "fetch all in rs; "
mySQL = mySQL & "commit; "
call query2table(mySQL,strconn)
%>

This does not seem to return anything.
Thanks
