EXCEPT and INTERSECT may be used in distributed queries, but are only executed on the local server and not pushed to the linked server. As such, using EXCEPT and INTERSECT in distributed queries may affect performance. You can use fast forward-only and static cursors in the result set when ...
8.Except和Intersect 比较两个查询的结果,返回非重复值。 EXCEPT 从左查询中返回右查询没有找到的所有非重复值。 INTERSECT 返回 INTERSECT 操作数左右两边的两个查询都返回的所有非重复值,即二者交集。 还是用刚刚的表,t1中是ABC,t2中是BCD 那么EXCEPT返回的是A INTERSECT返回的是BC Miranda.Tang 出处:http://ww...

可以有多个锚成员查询,其中每一个都需要与UNION ALL, UNION, INTERSECT, 或者 EXCEPT联合使用。当然也有多重的递归查询定义,每一个递归查询定义一定与UNION ALL联合使用。UNION ALL 操作符被用来连接最后的锚查询与第一个递归查询。接下来我们用实际立在来讨论一下CTE和递归CTE。
