Question

我不是最好的日期和sql日期。我有一个有3列的表。 Account No, Payment Date, Payment Amount。我需要做的只是返回7月份付款但8月没有付款的记录。

Answer 1

几种可能性

SELECT [Account No]
FROM YourTable
WHERE [Payment Date] >= '20130701' AND [Payment Date] < '20130801'
EXCEPT
SELECT [Account No]
FROM YourTable
WHERE [Payment Date] >= '20130801' AND [Payment Date] < '20130901'

或

SELECT [Account No]
FROM YourTable
WHERE [Payment Date] >= '20130701' AND [Payment Date] < '20130901'
GROUP BY [Account No]
HAVING MAX([Payment Date]) < '20130801'

Answer 2

这样的事情：

SELECT * FROM T as T1 
WHERE  YEAR([Payment Date])=2013 
       and MONTH([Payment Date])=7
       and NOT EXISTS(SELECT * FROM T 
                               WHERE T.[Account No]=T1.[Account No]
                                     and YEAR([Payment Date])=2013 
                                     and MONTH([Payment Date])=8
                      )

付款收到一个月但不是下一个月
