Hi All,

I have a fairly simple SQL statement that needs to be rewritten to take out the nested WHERE statement.

All help gratefully received :)
SELECT DISTINCT ecus.title, ecus.last_name, ecus.email_address, ecus.customer
 
FROM eord_item_aban 
INNER JOIN ecus ON eord_item_aban.ref_no = ecus.customer 
LEFT OUTER JOIN eord ON eord_item_aban.ref_no = eord.customer 
WHERE (eord_item_aban.date_request BETWEEN GETDATE() - 4 AND GETDATE() - 2) AND (eord_item_aban.ref_no NOT IN (
    SELECT customer FROM eord AS eord_1 WHERE (date_entered BETWEEN GETDATE() - 3 AND  GETDATE())))
