Question

在以下枢轴中重复行。如下图所示，Emp Name重复三次。如果我也使用订单，得到相同的结果。我做错了什么。我怎样才能得到正确的输出。谁能帮我吗。（使用SQL Server 2012）

SELECT 
    *
FROM
    (SELECT 
         e.EmpName, ClaimSource, TicketStatus 
     FROM 
         ClaimMaster c
     INNER JOIN 
         Allocation a ON c.ClaimMasterId = a.ClaimMasterId
     INNER JOIN 
         myUsers..EmpMaster e ON a.AllocatedToEmpId = e.AspUsername
     WHERE 
         TicketStatus IN ('First Review','Calling Pending','Analyst Action','Recalling') 
    ) m
PIVOT (
    COUNT(ClaimSource)
    FOR ClaimSource IN ([Aging Report],[Appeal],[Denied],[Rejected],[Special Project],[Eligibility],[Correspondence])
) n
PIVOT (
    COUNT(TicketStatus)
    FOR TicketStatus IN ([Recalling])
) o

期望的输出

如果我删除了TicketStatus列＆amp;枢轴然后我可以得到所需的输出。

如果我删除了TicketStatus列＆amp;枢轴，然后我可以得到所需的输出。

首先我的建议是使用条件聚合，这样你就可以同时聚合这两个条件。

SELECT
    e.EmpName
    ,COUNT(CASE WHEN ClaimSource = 'Aging Report' THEN ClaimSource END) as [Aging Report]
    ,COUNT(CASE WHEN ClaimSource = 'Appeal' THEN ClaimSource END) as [Appeal]
    ,COUNT(CASE WHEN ClaimSource = 'Denied' THEN ClaimSource END) as [Denied]
    ,COUNT(CASE WHEN ClaimSource = 'Rejected' THEN ClaimSource END) as [Rejected]
    ,COUNT(CASE WHEN ClaimSource = 'Special Project' THEN ClaimSource END) as [Special Project]
    ,COUNT(CASE WHEN ClaimSource = 'Eligibility' THEN ClaimSource END) as [Eligibility]
    ,COUNT(CASE WHEN ClaimSource = 'Correspondence' THEN ClaimSource END) as [Correspondence]
    ,COUNT(CASE WHEN TicketStatus = 'Recalling' THEN TicketStatus END) as [Recalling]
FROM ClaimMaster c
    INNER JOIN Allocation a ON c.ClaimMasterId = a.ClaimMasterId
    INNER JOIN myUsers..EmpMaster e ON a.AllocatedToEmpId = e.AspUsername
WHERE TicketStatus IN ('First Review','Calling Pending','Analyst Action','Recalling') 
GROUP BY
    e.EmpName

你基本上是在尝试基于ClaimSource和TicketStatus进行2种不同类型的聚合.PIVOT不能这样做。实际发生的事情您的第一个Pivot会创建额外的行，因为它还有票据状态。然后你的下一个枢轴，该列被旋转并计数，因此它将其关闭。但是因为所有其他列都存在，所以它实际上并不执行任何聚合。我只能从您的数据图像中假设您的员工没有任何RecallingTicketStatus。您可以进行第二轮聚合，而不是第二次转动：

SELECT
    EmpName
    ,SUM([Aging Report]) as [Aging Report]
    ,SUM([Appeal] as [Appeal]
    ,SUM([Denied]) as [Denied]
    ,SUM[Rejected]) as [Rejected]
    ,SUM([Special Project]) as [Special Project]
    ,SUM([Eligibility]) as [Eligibility]
    ,SUM([Correspondence]) as [Correspondence]
    ,COUNT(Recalling) as Recalling
FROM (
    SELECT e.EmpName, ClaimSource, TicketStatus FROM ClaimMaster c
    INNER JOIN Allocation a ON c.ClaimMasterId = a.ClaimMasterId
    INNER JOIN myUsers..EmpMaster e ON a.AllocatedToEmpId = e.AspUsername
    WHERE TicketStatus IN ('First Review','Calling Pending','Analyst Action','Recalling') 
) m
PIVOT (
    COUNT(ClaimSource)
    FOR ClaimSource IN ([Aging Report],[Appeal],[Denied],[Rejected],[Special Project],[Eligibility],[Correspondence])
) n
GROUP BY
    EmpName

或许更容易只为ClaimSource做透视，并进行标准聚合和Recalling的连接。但如果你这样做，我建议改为携带员工ID。

SELECT *
FROM
    (SELECT *
       FROM (
          SELECT e.EmpName, ClaimSource FROM ClaimMaster c
          INNER JOIN Allocation a ON c.ClaimMasterId = a.ClaimMasterId
          INNER JOIN myUsers..EmpMaster e ON a.AllocatedToEmpId = e.AspUsername
          WHERE TicketStatus IN ('First Review','Calling Pending','Analyst Action') 
       ) m
       PIVOT (
          COUNT(ClaimSource)
          FOR ClaimSource IN ([Aging Report],[Appeal],[Denied],[Rejected],[Special Project],[Eligibility],[Correspondence])
       ) n
    ) t
    INNER JOIN (
       SELECT
          SELECT e.EmpName, COUNT(TicketStatus) as Recalling FROM ClaimMaster c
          INNER JOIN Allocation a ON c.ClaimMasterId = a.ClaimMasterId
          INNER JOIN myUsers..EmpMaster e ON a.AllocatedToEmpId = e.AspUsername
          WHERE TicketStatus IN ('Recalling') 
    ) t2
    ON T1.EmpName = t2.EmpName

要在将来逐步解决查询的每个部分，请解决此问题。因此，使用1个数据透视看结果。有了TicketStatus，如果你这样做，你应该举起一面旗帜。
