Howdy, Nacef,
Try this,
SELECT a.userid
FROM orders a
JOIN orders b
USING (userid)
WHERE a.productid = 1
AND b.productid = 2
Best,
Oliveiros

Subject: [SQL] Performing intersection without intersect operator
Hi all,
I want to perform an intersection between several select queries but without using the INTERSECT keyword.
select userid from orders where productid=1 INTERSECT select userid from orders where productid=2
I want to transform it without the INTERSECT.
Thanks to all
Nacef
