如何排除一个值并使具有该值的所有内容不在计算中

Question

一个Policy Number 可以有多个不同的ClassCode 并且只有一个Premium 的总量。在我的 SSRS 报告中，我希望能够创建参数 ClassCode，并且如果我排除（取消选中）其中至少一个 ClassCode，则需要不在计算中包含保费的整个保单编号。 可以说，如果我想排除 ClassCode 58，那么 1,644.00 的 Premium 不应该出现在我的报告结果中。

我试图在我的查询AND ClassCode <> 58 中说，但它只排除了一行并保留了高级注释。但我的目标是排除所有具有 ClassCode 58 的内容。

SELECT policynumber,
       classcode,
       /*
       Using ROW_NUMBER() to check if it's the first record in the join and returns the Premium value if so, otherwise it will display 0. 
       The ORDER BY (SELECT 0) is there just because I don't need the row number to be based on any explicit order.
       */
       CASE
         WHEN ROW_NUMBER()
                OVER (
                  PARTITION BY cte1.policynumber
                  ORDER BY (SELECT 0)) = 1 THEN premium
         ELSE 0
       END        AS Premium,
       c.yearnum  TransEffYearNum,
       c.monthnum TransEffMonthNum
FROM   cte1
       INNER JOIN cte2
               ON cte1.policynumber = cte2.policynumber
       RIGHT JOIN tblcalendar c
               ON c.yearnum = Year(cte1.policyeffectivedate)
                  AND c.monthnum = Month(cte1.policyeffectivedate)
WHERE  c.yearnum = 2016
       AND classcode <> 58  

Answer 1

您应该首先排除所有具有您要设置的 ClassCode 的 Policy Numbers。 所以而不是 where c.YearNum = 2016 AND ClassCode <> 58

使用

where  PolicyNumber NOT IN
(SELECT  PolicyNumber 
 From cte1 inner join cte2 on cte1.PolicyNumber=cte2.PolicyNumber
 WHERE ClassCode = 58);

应该这样做。

Answer 2

如果您想消除策略 3 的所有行，这可能会起作用。

SELECT policynumber,
       classcode,
       /*
       Using ROW_NUMBER() to check if it's the first record in the join and returns the Premium value if so, otherwise it will display 0. 
       The ORDER BY (SELECT 0) is there just because I don't need the row number to be based on any explicit order.
       */
       CASE
         WHEN ROW_NUMBER()
                OVER (
                  PARTITION BY cte1.policynumber
                  ORDER BY (SELECT 0)) = 1 THEN premium
         ELSE 0
       END        AS Premium,
       c.yearnum  TransEffYearNum,
       c.monthnum TransEffMonthNum
FROM   cte1
       INNER JOIN cte2
               ON cte1.policynumber = cte2.policynumber
       RIGHT JOIN tblcalendar c
               ON c.yearnum = Year(cte1.policyeffectivedate)
                  AND c.monthnum = Month(cte1.policyeffectivedate)
WHERE  c.yearnum = 2016
       AND cte2.policynumber NOT IN (SELECT policynumber FROM cte2 WHERE ClassCode = 58 and policynumber IS NOT NULL);
