Question

此select语句返回每行timeid的所有值。连接使用正确的唯一值连接。我已经尝试了内部连接/左外/右外部和完全也选择明显无济于事。

SELECT
    timed.timeid AS [Time Number], 
    emp.firstname AS [First Name], 
    emp.surname AS [Surame], 
    emp.empid AS [Employee Number], 
    timed.ver AS [Ver],
    timed.tdate AS [Date], 
    shifts.code AS [Code], 
    timed.stime AS [Start], 
    timed.etime AS [End], 
    DATEDIFF(HOUR, timed.stime, timed.etime) AS [Hours]
FROM 
    emp 
    INNER JOIN timed ON emp.divid = timed.divid
    INNER JOIN shifts ON timed.shiftid = shifts.shiftid     

Time Number First Name  Surame  Employee Number Ver     Date    Code      Start        End     Hours

正如上面结果的一个小例子所示，它是将timeid添加到所有结果中，也可能是除emp表中的其他值之外的其他值。

所需的输出就像是。

Time Number First Name  Surame  Employee Number Ver     Date    Code      Start        End     Hours
