how do I return a cursor from a function?

[Pia Gronqvist]

I've got this in MySQL Query Browser, but it won't work:

DELIMITER $$

create function test_fn(param integer)
returns cursor
begin
declare some_cur cursor for select * from foo where bar = param;
return some_cur;
end $$

DELIMITER ;

Please tell me what is wrong.

Thank you,
Pia
