visual-studio-2010 - sql递归错误无效列名CTE

Question

我已经完成了 CTE，它工作正常，但我需要得到最后一个节点的总和，所以问题是当我添加 T1.Debit 列来计算它给我一个无效的列名“借方”！在线的 ***

ALTER Function [dbo].[SubTopics_GetSum]
 -- Add the parameters for the stored procedure here
    (
    @TopicID int
    )
RETURNS TABLE 
AS
RETURN 
(
    -- Add the SELECT statement with parameter references here
    WITH cte
    AS (
        SELECT
            T1.TopicID,
            T1.Code,
            T1.Description,
            T1.ParentID,
            T1.ParentID AS NewParentID,
            CAST(T1.Code AS nvarchar(MAX)) AS TopicCode,
            CAST(T1.Description AS nvarchar(MAX)) AS TopicDescription,
            isnull((Accounting.DocumentDetail.Debit),0) AS Debit,
            isnull((Accounting.DocumentDetail.Credit),0) AS Credit
        FROM Accounting.Topics AS T1
            LEFT OUTER JOIN Accounting.DocumentDetail
                ON T1.TopicID = Accounting.DocumentDetail.TopicFK
        where NOT EXISTS(
                        SELECT
                            T2.TopicID,
                            T2.Code,
                            T2.Description,
                            T2.ParentID,
                            isnull((Accounting.DocumentDetail.Debit),0) AS Debit,
                            isnull((Accounting.DocumentDetail.Credit),0) AS Credit
                        FROM Accounting.Topics AS T2
                            LEFT OUTER JOIN Accounting.DocumentDetail
                                ON T2.TopicID = Accounting.DocumentDetail.TopicFK
                        WHERE (ParentID = T1.TopicID)
                        )
        UNION ALL
        SELECT
            c.TopicID,
            c.Code,
            c.Description,
            c.ParentID,
            T1.ParentID AS NewParentID,
            CAST(T1.Code AS nvarchar(MAX)) + c.TopicCode AS TopicCode,
            CAST(T1.Description AS nvarchar(MAX)) + ' - ' + c.TopicDescription AS TopicDescription,
            ***   isnull((T1.Debit),0)+isnull(c.Debit,0) AS Debit,--IN THIS LINE error 'Invalid Column Name 'Debit''
            isnull(c.Credit,0) AS Credit
        FROM cte AS c
            INNER JOIN Accounting.Topics AS T1
                ON T1.TopicID = c.NewParentID
        )

    SELECT isnull(sum(Debit),0)AS Debit,
        isnull(sum(Credit),0)AS Credit
    FROM cte AS c
    WHERE (NewParentID = @TopicID)
)

让我知道我的代码有什么问题！

实际上它并没有返回我最后一个节点的借方，贷方总和...... !!! 检查以下图片

我认为下面的代码会有所帮助，

ALTER FUNCTION [dbo].[Subtopics_getsum] 
-- Add the parameters for the stored procedure here 
(@TopicID INT) 
returns TABLE 
AS 
    RETURN ( 
      -- Add the SELECT statement with parameter references here 
      WITH cte 
           AS (SELECT T1.topicid, 
                      T1.code, 
                      T1.description, 
                      T1.parentid, 
                      T1.parentid                                     AS 
                      NewParentID 
                      , 
                      Cast(T1.code AS NVARCHAR(max)) 
                      AS TopicCode, 
                      Cast(T1.description AS NVARCHAR(max))           AS 
                      TopicDescription, 
                      Isnull(( accounting.documentdetail.debit ), 0)  AS Debit, 
                      Isnull(( accounting.documentdetail.credit ), 0) AS Credit 
               FROM   accounting.topics AS T1 
                      LEFT OUTER JOIN accounting.documentdetail 
                                   ON T1.topicid = 
                                      accounting.documentdetail.topicfk 
               WHERE  NOT EXISTS(SELECT T2.topicid, 
                                        T2.code, 
                                        T2.description, 
                                        T2.parentid, 
    Isnull(( accounting.documentdetail.debit ), 0) 
    AS 
    Debit, 
    Isnull(( accounting.documentdetail.credit ), 0) AS 
    Credit 
    FROM   accounting.topics AS T2 
    LEFT OUTER JOIN accounting.documentdetail 
    ON T2.topicid = 
    accounting.documentdetail.topicfk 
    WHERE  ( parentid = T1.topicid ))) 
    SELECT Isnull(Sum(debit), 0) AS Debit, 
    Isnull(Sum(credit), 0)AS Credit 
    FROM   cte AS c 
    WHERE  ( newparentid = @TopicID )
    )

Answer 2

我想你Accounting.Topics没有专栏Debit。

UPDTAE

isnull(( T1.Debit ),0)+isnull(c.Debit,0) AS Debit,--IN THIS LINE error 'Invalid Column Name 'Debit'' isnull(c.Credit,0) AS Credit FROM cte AS c INNER JOIN Accounting.Topics AS T1 ON T1.TopicID = c.NewParentID

在上面的代码中，您T1.Debit指的是Accounting.Topics.
