本文实例讲述了SQL Server简单实现数据的日报和月报功能。分享给大家供大家参考，具体如下：

--320, SQL SERVER 日报
--查询2009-01-01当天客户A1,A2,A3的订单数量
SELECT Cust_Name
, CONVERT(CHAR(10), Order_Date, 120) Order_Date
, SUM(Qty) Qty
FROM Orders_Big
WHERE 1=1
AND Cust_Name IN ('A1', 'A2', 'A3')
AND Order_Date >= '2009-01-01'
AND Order_Date<'2009-01-02'
/*AND Order_Date -- BETWEEN...AND相当于>=和<=
BETWEEN '2009-01-01'
AND '2009-01-02'*/
GROUP BY Cust_Name
, CONVERT(CHAR(10), Order_Date, 120)
ORDER BY 2, 1
--3..
