Please provide sql code?

Answer 1

您可以使用CROSS APPLY取消删除列：

SELECT  T.EmpCode, i.InOut, T.TransDate
FROM    Timing T
        CROSS APPLY (VALUES (T.Login), (T.Logout)) i (InOut);

您也可以使用UNPIVOT：

SELECT  upvt.EmpCode, upvt.InOut, upvt.TransDate
FROM    Timing T
        UNPIVOT
        (   InOut
            FOR [Type] IN (Login, Logout)
        ) upvt;
