Question

select Tin.TimeIn,Tin.Date,Tout.TimeOut,tout.Date
from AttendanceTimeIn as Tin
Join AttendanceTimeOut as Tout on Tin.Code=tout.Code
where tout.Code=14 and Tin.Date between `('2014-01-22')` and `('2014-01-23')`

它的输出是：

Time in     Date            TimeOut Date
07:31       2014-01-22      04:47   2014-01-22
07:31       2014-01-22      10:46   2014-01-23
10:41       2014-01-23      04:47   2014-01-22
10:41       2014-01-23      10:46   2014-01-23

我只想要匹配日期的记录

Answer 1

试试这个

Select Tin.TimeIn,Tin.Date,Tout.TimeOut,tout.Date
from AttendanceTimeIn as Tin
Join AttendanceTimeOut as Tout on Tin.Code=tout.Code and Tin.Date = Tout.Date
where tout.Code=14

<强>（OR）

Select Tin.TimeIn,Tin.Date,Tout.TimeOut,tout.Date
from AttendanceTimeIn as Tin
Join AttendanceTimeOut as Tout on Tin.Code=tout.Code and Tin.Date = Tout.Date
where tout.Code=14 AND Tin.Date between `('2014-01-22')` and `('2014-01-23')`

Answer 2

尝试这一点，我确保即使没有超时

也会显示Time-in

SELECT  Tin.TimeIn,
        Tin.Date,
        Tout.TimeOut,
        tout.Date
FROM    AttendanceTimeIn As Tin
        Left Outer Join AttendanceTimeOut As Tout
            On Tin.Code=tout.Code
            And Tin.Date = tout.Date
WHERE   Tout.Code=14
        And Tin.Date Between '2014-01-22' And '2014-01-23'

Answer 3

您的预期输出是否正确？

Time in     Date            TimeOut  Date
07:31       2014-01-22      04:47    2014-01-22 
10:41       2014-01-23      10:46    2014-01-23

您可以在WHERE子句

上添加条件

 WHERE tout.Code=14 and Tin.Date between `('2014-01-22')` and `('2014-01-23')`
  AND (tin.Date = tout.Date);

sql命令显示来自两个相同日期表的时间和超时，由员工代码配对
