How to get a query to run faster
I have a query that takes a while to run and sometimes times out. Is there a better way to write the query below to run faster?
SELECT a.confirm_date, a.so_br_id, a.so_id, a.so_line_nbr, a.confirm_qty, a.orig_assign_qty,
b.qty_backordered, b.qty_ordered, b.qty_shipped, a.bo_reason_code, a.part_id, c.cust_id, b.vendor_code
FROM CSI.SO_CARTON_DETAIL a, csi.or_line b, csi.or_header c
WHERE a.CONFIRM_DATE >= @variable ('Start Date')
and a.CONFIRM_DATE <= @variable ('End Date')
and a.CONFIRM_QTY <> a.ORIG_ASSIGN_QTY
and a.so_br_id = b.so_br_id
and a.so_id = b.so_id
and a.so_line_nbr = b.so_line_nbr
and a.so_br_id = c.so_br_id
and a.so_id = c.so_id
and b.qty_backordered > 0
ORDER BY a.confirm_date, c.cust_id, a.so_br_id, a.so_id

To tell you the truth my knowledge hasn't reached the point of indexing but I do know it helps with the speed which is about what I know for indexing.
