SELECT  

P.EmployeeId,
(P.Amount*1)*T.RegularHours as RegularEarnings
,(P.Amount*1.5)*T.OTHours as OvertimeEarnings 
,(P.Amount*2)*T.DOTHours as DoubleOvertimeEarnings
,((P.Amount*1)*T.RegularHours)+((P.Amount*1.5)*T.OTHours )+((P.Amount*2)*T.DOTHours)+((SELECT ISNULL(SUM(AMOUNT),0) FROM EmployeeEarning WHERE EmployeeId=T.EmployeeId)) as GrossPay
FROM TimeSheet  as T
INNER JOIN PayInformation as P ON T.EmployeeId=P.EmployeeId

以上是我的选择语句，它以列格式返回我的收入。我希望unpivot我的结果表employeeId有两列，一列是收入类型，第二列是收入金额。

我已经完成了简单的 unpivote

select unpvt.car_id, unpvt.attribute, unpvt.value
from @cars c
unpivot ( 
 value 
 for attribute in (Make, Model, Color)
) unpvt

但现在卡住了，因为我必须取消在 select 语句中计算的数据透视表值。

我尝试了更多，这是我最新的代码

SELECT unpvt.EmployeeId, unpvt.Earning, unpvt.Amount
FROM 
(SELECT    
P.EmployeeId,
(P.Amount*1)*T.RegularHours as RegularEarnings
,(P.Amount*1.5)*T.OTHours as OvertimeEarnings 
,(P.Amount*2)*T.DOTHours as DoubleOvertimeEarnings
,((P.Amount*1)*T.RegularHours)+((P.Amount*1.5)*T.OTHours )+((P.Amount*2)*T.DOTHours)+((SELECT ISNULL(SUM(AMOUNT),0) FROM EmployeeEarning WHERE EmployeeId=T.EmployeeId)) as GrossPay
FROM TimeSheet  as T
INNER JOIN PayInformation as P ON T.EmployeeId=P.EmployeeId )as c
unpivot ( 
Amount
for Earning in (RegularEarnings,OvertimeEarnings,DoubleOvertimeEarnings)
)unpvt

现在我收到错误

The type of column "OvertimeEarnings" conflicts with the type of other columns specified in the UNPIVOT list.
