衆多工會，更簡單的方法？

Question

我正在使用下面的查詢並獲取我想要的結果，我不禁想到，有可能比使用不同的where子句反覆重複該代碼更好的方法？建議？

這裏是我的結果：

Answer 1

是的，有一個更好的辦法。您可以在CTE定義組，然後用組GROUP BY：

WITH HHSUMMARY AS (
     SELECT B.HouseholdId, SUM(B.Balance) AS AUM, 
      SUM(B.TradeRevenue + B.TrailRevenue + B.AdvisoryRevenue) AS Revenue, 
      (CASE WHEN SUM(B.BALANCE) < 25000 THEN '<25000' 
        WHEN SUM(B.BALANCE) < 50000 THEN '25K-50K' 
        . . . 
       END) as [ACCT BALANCE CAT] 
     FROM BookSegmentation.BookSegmentationDataset B 
     WHERE B.RepName = 'Rep' 
     GROUP BY B.HouseholdId 
    ) 
SELECT COALESCE([ACCT BALANCE CAT], 'Total'), 
     COUNT(HouseholdID) AS HH, 
     CAST(COUNT(HouseholdId) AS DECIMAL(18,2))/(SELECT CAST(COUNT(HouseholdId) AS DECIMAL(18,2)) FROM HHSUMMARY) AS [% HH], 
     SUM(AUM) AS [HH AUM], 
     SUM(AUM)/(SELECT SUM(AUM) FROM HHSUMMARY) AS [HH AUM %], 
     SUM(Revenue) AS REVENUE, 
     SUM(Revenue)/(SELECT SUM(Revenue) FROM HHSUMMARY) AS [% REV], 
     SUM(Revenue)/SUM(AUM) AS [EFFICIENCY %] 
FROM HHSUMMARY 
GROUP BY GROUPING SETS (([ACCT BALANCE CAT]),()); 

注意使用GROUPING SETS計算總。您也可以使用ROLLUP。
