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 --321. ORACLE 日报 --查询2009-01-01当天客户A1,A2,A3的订单数量 SELECT Cust_Name , TO_CHAR(Order_Date, 'YYYY-MM-DD') Order_Date --方法一:转换成字符串类型 --, TRUNC(Order_Date) Order_Date --方法二:将时分秒信息截断 , SUM(Qty) Qty FROM Orders_Big WHERE 1=1 AND Cust_Name IN ('A1', 'A2', 'A3') AND Order_Date >= DATE'2009-01-01' AND Order_Date<DATE'2009-01-02' GROUP BY Cust_Name , TO_CHAR(Order_Date, 'YYYY-MM-DD')--方法一 --, TRUNC(Order_Date)--方法二 ORDER BY 2, 1 ------------------------------10.2------------------------------------ --326,SQL SERVER 月报 SELECT Cust_Name , CONVERT(CHAR(7), Order_Date, 120) Order_YrMs , CAST(CONVERT(CHAR(7), Order_Date, 120) + '-01' AS DATETIME) 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<'2009-02-01' GROUP BY Cust_Name , CONVERT(CHAR(7), Order_Date, 120) ORDER BY 2, 1 --326, ORACLE SELECT Cust_Name , TO_CHAR(Order_Date, 'YYYY-MM') Order_YrMs --方法1 --, TRUNC(Order_Date, 'MM') Order_Date--方法2 , SUM(Qty) Qty FROM Orders_Big WHERE 1=1 AND Cust_Name IN ('A1', 'A2', 'A3') AND Order_Date >= DATE'2009-01-01' AND Order_Date<DATE'2009-02-01' GROUP BY Cust_Name , TO_CHAR(Order_Date, 'YYYY-MM')--方法1 --, TRUNC(Order_Date, 'MM')--方法2 ORDER BY 2, 1
