同一张表中的多个内部联接

Question

从两个表设置单个内部联接非常简单，如下代码。

SELECT A.[Col1], A.[Col2], A.[Col3], A.[Col4], B.[ColJ], B.[ColK] 
  FROM Table_A AS A
    INNER JOIN Table_B AS B
    ON A.[Col1] = B.[ColJ]

但是，所讨论的表非常复杂，将需要多个联接。像这样：

SELECT A.[Col1], A.[Col2], A.[Col3], A.[Col4], B.[ColJ], B.[ColK] 
  FROM Table_A AS A
    INNER JOIN Table_B AS B
    ON A.[Col1] = B.[ColJ]
    INNER JOIN Table_B AS C
    ON A.[Col2] = C.[ColK]

但是我无法使其工作。

有什么建议吗？

谢谢

我的实际代码：

SELECT
  j.[AA Number]
  ,j.[AA Role]
  ,j.[Project Name] AS [j Project Name]
  ,j.Series AS [j Series]
  ,j.[Paper No]
  ,j.[Task Name] AS [j Task Name]
  ,j.Amount
  ,a.[Project Name] AS [TEP_Projects_Tasks_Full Project Name]
  ,a.[Project Number]
  ,a.[Task Name] AS [TEP_Projects_Tasks_Full Task Name]
  ,a.[Expenditure Organization]
FROM
  TEP_Payments_Table as j
  inner JOIN TEP_Projects_Tasks_Full as a
    ON j.[Project Name] = a.[Project Name]
  inner join TEP_Projects_Tasks_Full as b
    on j.[Task Name] = b.[Task Name]

我得到的结果如下：

如您所见-任务名称未正确加入，它将返回所有任务名称，而不是正确的名称（在本例中为采样）。

如果我使用a而不是b（按照下面的评论），则会出现以下错误：

您可以尝试选择b.[Task Name] AS [TEP_Projects_Tasks_Full Task Name]而不是a.[Task Name] AS [TEP_Projects_Tasks_Full Task Name]

SELECT
  j.[AA Number]
  ,j.[AA Role]
  ,j.[Project Name] AS [j Project Name]
  ,j.Series AS [j Series]
  ,j.[Paper No]
  ,j.[Task Name] AS [j Task Name]
  ,j.Amount
  ,a.[Project Name] AS [TEP_Projects_Tasks_Full Project Name]
  ,a.[Project Number]
  ,b.[Task Name] AS [TEP_Projects_Tasks_Full Task Name]
  ,a.[Expenditure Organization]
FROM
  TEP_Payments_Table as j
  inner JOIN TEP_Projects_Tasks_Full as a
    ON j.[Project Name] = a.[Project Name]
  inner join TEP_Projects_Tasks_Full as b
    on j.[Task Name] = b.[Task Name]
