WITH ROLLUP 在生成包含小计和合计的报表时，ROLLUP 运算符很有用。ROLLUP 运算符生成的结果集类似于 CUBE 运算符所生成的结果集。
复制代码 代码如下:
SELECT [Source], COUNT(*) AS OrderTotal FROM [ExternalOrder] Where OrderStatus=1 AND (CheckPayment=1 ) and TicketDate >= '2012-11-1' AND TicketDate < '2012-12-1' GROUP BY [Source] WITH ROLLUP Order by [Source] desc
