嵌套 SQL MS Access 的参数输入

问题描述

SELECT [doc type],[Open Amount],[customer number],COUNT([customer number]) As CountCustomerNumber,SUM(IIF([Open Amount]>'0',0)) AS sum_open_amount_pos,SUM(IIF([Open Amount]<'0',0)) As sum_open_amount_neg         
FROM 
      (SELECT d.[customer number] & d.[membership number] AS CustMemb,d.[customer number],agg.[doc type],d.[Open Amount]
        FROM  (SELECT [doc type],d.[Open Amount]
               FROM   data
               WHERE  [doc type] = 'RU'
              ) agg
        INNER JOIN [data] d                                   
           ON  d.[customer number] = agg.[customer number]
        GROUP  BY d.[customer number] & d.[membership number],agg.[doc type]
      ) AS sub
GROUP  BY [doc type],[Open Amount]
HAVING COUNT([customer number]) = 1

大家好，

我在 MS Access 中运行时得到 d.[Open Amount] 的参数输入。

有谁知道是什么导致了这种情况
