Question

我希望SQL添加两列中的数字，并将两个数字的平均值放在一个单独的列中。

我目前正在以这种方式使用AVG：

AVG(InpCount + OutCount) OVER (PARTITION BY ProcedureID) as AverageCount,
AVG(InpAmount + OutAmount) OVER (PARTITION BY ProcedureID) as AverageAmount,

我希望SQL给我一个InpCount + OutCount的平均值，并将该平均值放在上面的AverageCount列中。如果我也可以对InpAmount + InpCount字段执行此操作，那么我就完成了。

以下是查询：

SELECT M.ProcedureID, 
       M.SegmentDateTime,
       M.PriceID,
       L.DrugID,
       L.NdcDinNumber,
       L.Name,
       M.DeptCorporation,
       M.InpAmount,
       M.InpCount,
       M.OutAmount,
       M.OutCount,

       SUM(InpCount) OVER (PARTITION BY ProcedureID) as INtotal,
       SUM(InpAmount) OVER (PARTITION BY ProcedureID) as  IN$Total,
       SUM(OutCount) OVER (PARTITION BY ProcedureID) as OUTtotal,
       SUM(OutAmount) OVER (PARTITION BY ProcedureID) as  OUT$Total,
       SUM(InpCount + OutCount) OVER (PARTITION BY ProcedureID) as TotalCount,
       SUM(InpAmount + OutAmount) OVER (PARTITION BY ProcedureID) as TotalAmount,
       AVG(InpCount + OutCount) OVER (PARTITION BY ProcedureID) as AverageCount,
       AVG(InpAmount + OutAmount) OVER (PARTITION BY ProcedureID) as AverageAmount,
       row_number() over (partition by ProcedureID order by (select NULL)) as SeqNum

FROM BarRevenueByProcedurePriceInfo M LEFT JOIN
     DPhaDrugData L
     ON M.ProcedureID = L.BillNumber
WHERE DeptID = '010.4730' AND SegmentDateTime = '2013-12-31 00:00:00.000' AND
      (M.InpCount > '0' or M.OutCount > '0') AND DrugID = 'LIDO5GEL4'

Answer 1

您应该明确计算平均值。平均值用于计算不同记录的平均值，而不是不同列的平均值。

您可能希望使用SUM(InpAmount + OutAmount) / 2代替AVG(InpAmount + OutAmount)，而使用SUM(InpCount + OutCount) / 2代替AVG(InpAmount + OutAmount)。

现场平均整数;不是行条目
