單個連接查詢中的不同和總和

Question

我有以下連接查詢。我希望記錄與 c.checkid 以及收入總和不同。我如何在一個查詢中同時執行這兩項？

select c.CheckID,cv.CheckID,Earnings,TaxableEarnings,Amount,EmployeeCode, CheckDate FROM [Customers0].[pay].[CheckVendorCalc] as cv
inner join  [Customers0].[pay].[Checks] as c
on cv.checkid=c.checkid
where
c.CheckDate BETWEEN '2022-01-01' AND '2022-12-31' and 
c.CustomerID=360 and
c.EmployeeCode='01' and
(cv.TaxableEarnings !=null or cv.TaxableEarnings!=0)

Answer 1

您可以使用GROUP BY 。 SELECT子句中的任何非聚合列都必須出現在GROUP BY子句中。 您可以在此處找到更多信息。

SQL：

select
  c.CheckID,
  SUM(Earnings) as totalearning
FROM
  [Customers0].[pay].[CheckVendorCalc] as cv
  inner join [Customers0].[pay].[Checks] as c on cv.checkid = c.checkid
where
  c.CheckDate BETWEEN '2022-01-01'
  AND '2022-12-31'
  and c.CustomerID = 360
  and c.EmployeeCode = '01'
  and (
    cv.TaxableEarnings != null
    or cv.TaxableEarnings != 0)
group by
  c.CheckID
order by
  c.CheckID
