sql - 来自两个select语句的总和

我们的员工每周获得佣金，由于奖金结构的原因，我必须计算两个单独的星期，然后将两个星期相加。

我有以下SQL语句，它获得两个单独的星期结果

    SELECT  PerceptionistID, SSNLastFour, CommissionPay,
        PTOPay, HolidayPay, Overtime, TotalPay
    FROM [dbo].fnCalculateCommissionForWeekOf(@MondayOfCurrentWeek)

    UNION

    -- Need to get the following week's data and sum the two together
    SELECT  PerceptionistID, SSNLastFour, CommissionPay,
        PTOPay, HolidayPay, Overtime, TotalPay
    FROM [dbo].fnCalculateCommissionForWeekOf(@MondayOfFollowingWeek)

这为我获取了我需要的数据，但我想将两个结果合并到一个表中，这些表具有相同的列，但是将某些列加在一起(CommissionPay，PTOPay，HolidayPay，Overtime，TotalPay)。做这个的最好方式是什么？我正在使用SQL Server 2008 R2。

最佳答案

试试这个

SELECT PerceptionistID, SSNLastFour, SUM(CommissionPay) CommissionPay,
        SUM(PTOPay) PTOPay, SUM(HolidayPay) HolidayPay, SUM(Overtime) Overtime, SUM(TotalPay) TotalPay
FROM
(
    SELECT  PerceptionistID, SSNLastFour, CommissionPay,
        PTOPay, HolidayPay, Overtime, TotalPay
    FROM [dbo].fnCalculateCommissionForWeekOf(@MondayOfCurrentWeek)

    UNION ALL

    -- Need to get the following week's data and sum the two together
    SELECT  PerceptionistID, SSNLastFour, CommissionPay,
        PTOPay, HolidayPay, Overtime, TotalPay
    FROM [dbo].fnCalculateCommissionForWeekOf(@MondayOfFollowingWeek)
) t
GROUP BY PerceptionistID, SSNLastFour
