Question

我有一个下面设置的表格，我想要提取的是所有拥有HH1但在5天内没有DIS的帐户的列表。

AccountNo   Code    Date
125487  HH1 17/11/2013
125487  DIS 18/11/2013
123368  HH1 16/11/2013
124587  HH1 10/09/2013

我尝试使用NOT EXISTS，但是它只返回过去5天内的记录？

SELECT     mx.AccountNo
                , mx.Code
                , mx.Date
FROM         dbo.tblmtx AS mx INNER JOIN
                dbo.tblM AS m ON m.AccountNo = mx.AccountNo 
WHERE     (Code IN ('HH1')) AND (FA = 'R') AND
              (mx.Date > GETDATE()-5 ) 
           AND 
                NOT EXISTS 
            ( SELECT 1 FROM  dbo.tblMaTx AS mx2
                WHERE mx2.AccountNo = mx.AccountNo 
                     AND mx2.Date >= GETDATE()-5
                     AND mx2.Code = 'DIS'
                     AND mx2.FA = 'R'
                     )
                    GROUP BY mx.AccountNo
                , mx.Code
                , mx.Date
        ORDER BY mx.AccountNo

我哪里错了？

Answer 1

获取过去五天内有DIS的帐户

select accountNo from accounts where acc.code = 'DIS' and  acc.date > GETDATE()-5

获取DO所拥有的帐户

select accountNo from accounts where acc.code = 'HH1'

然后：

 select accountNo from accounts where acc.code = 'HH1' and accounts.accountNo not in 
   (select accountNo from accounts acc2 where acc2.code = 'DIS' and  
               acc2.date > GETDATE()-5 )

Answer 2

试试这个

SELECT a.AccountNo, a.Code, a.[Date]
FROM [YourTable] a
        LEFT OUTER JOIN [YourTable] a2
        ON a.AccountNo = a2.AccountNo
        AND a2.[Date] BETWEEN DATEADD(day, -5, a.[Date]) AND a.[Date]
WHERE a.Code = 'HH1'
    AND a2.AccountNo IS NULL

选择查询中的NOT EXISTS以获得结果
