SQL Server简单实现数据的日报和月报功能

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
