Hi, I have created a view like this :

CREATE VIEW v1 AS (SELECT orderno,weekday,time FROM t1,t2 where
t1.orderno=t2.orderno);

if I create a SQL statment:

(SELECT orderno FROM v1 WHERE weekday='MON' ORDER BY orderno)
UNION
(SELECT orderno FROM v1 WHERE weekday='WED' ORDER BY orderno)
UNION
(SELECT orderno FROM v1 WHERE weekday='FRI' ORDER BY orderno);

Will the whole result will be sorted by the field orderno?

Thanks,
WeiShang
