NOT IN을 사용할 때 쿼리 성능을 향상시키는 방법

Question

여러 테이블을 여러 테이블에 조인하고 있습니다.

내 최종 결과에서 각 PolicyNumber에 대해 여러 ClassCode가 있습니다. 그렇게 보이는 :

지금 내가 SSRS에서 @ClassCode 매개 변수가 선택이 끝난 된 경우 PaidLosses으로 전체 PolicyNumber를 제외해야합니다. 그래서 NOT IN을 사용하여 PolicyNumber을 제거하면 영원히 돌아갑니다.

select  
      cte1.PolicyNumber, 
      cte1.TransactionEffectiveDate, 
      cc.ClassCode, 
      CASE 
       WHEN ROW_NUMBER() OVER (PARTITION BY cte1.QuoteID, cte1.PolicyNumber, cc.TransactionEffectiveDate ORDER BY (SELECT 0))=1 THEN cte1.WP 
       ELSE 0 
      END as WP--, 
from  cte1 inner join tblClassCodesPlazaCommercial cc on cte1.PolicyNumber=cc.PolicyNumber AND cte1.QuoteID=cc.QuoteID AND cte1.TransactionEffectiveDate=cc.TransactionEffectiveDate 
      AND cc.PolicyNumber IN (SELECT PolicyNumber FROM tblClassCodesPlazaCommercial WHERE ClassCode NOT IN (@ClassCode)) 

필자의 경우 쿼리 성능을 향상시키는 다른 방법이 있습니까?

DECLARE @ClassCode int = 5151 
;with cte1 
as 
(
SELECT  QuoteID, 
      CONVERT(VARCHAR(10),TransactionEffectiveDate,101) as TransactionEffectiveDate, 
      PolicyNumber, 
      SUM(WrittenPremium) as WP       
FROM  PlazaInsuranceWPDataSet  

WHERE  State IN ('CA','NV','AZ') 
GROUP BY  
      PolicyNumber, 
      QuoteID, 
      TransactionEffectiveDate  
), 
cte3 
as 
(
select  
      cte1.PolicyNumber, 
      cte1.TransactionEffectiveDate, 
      cc.ClassCode, 
      CASE 
       WHEN ROW_NUMBER() OVER (PARTITION BY cte1.QuoteID, cte1.PolicyNumber, cc.TransactionEffectiveDate ORDER BY (SELECT 0))=1 THEN cte1.WP 
       ELSE 0 
      END as WP--, 
from  cte1 inner join tblClassCodesPlazaCommercial cc on cte1.PolicyNumber=cc.PolicyNumber AND cte1.QuoteID=cc.QuoteID AND cte1.TransactionEffectiveDate=cc.TransactionEffectiveDate 
      AND cc.PolicyNumber IN (SELECT PolicyNumber FROM tblClassCodesPlazaCommercial WHERE ClassCode NOT IN (@ClassCode)) 
) 
select 
     c.YearNum, 
     c.MonthNum, 
     SUM(WP) as WP   
from cte3 RIGHT JOIN tblCalendar c ON c.YearNum=YEAR(TransactionEffectiveDate) AND c.MonthNum=MONTH(TransactionEffectiveDate) 
WHERE c.YearNum <>2017 
GROUP BY  
      c.YearNum, 
      c.MonthNum 
ORDER BY c.YearNum desc, 
      c.MonthNum

이 CTE3를 들어, 당신이이 방법을 쓸 수 있다고 생각, 그것은

cte3 
as 
(
select  
      cte1.PolicyNumber, 
      cte1.TransactionEffectiveDate, 
      cc.ClassCode, 
      CASE 
       WHEN ROW_NUMBER() OVER (PARTITION BY cte1.QuoteID, cte1.PolicyNumber, cc.TransactionEffectiveDate ORDER BY (SELECT 0))=1 THEN cte1.WP 
       ELSE 0 
      END as WP--, 
from  cte1 
inner join tblClassCodesPlazaCommercial cc 
on cte1.PolicyNumber=cc.PolicyNumber 
    AND cte1.QuoteID=cc.QuoteID 
    AND cte1.TransactionEffectiveDate=cc.TransactionEffectiveDate 

where cc.ClassCode NOT IN (@ClassCode)) 
    )
