如何调试“每个 GROUP BY 表达式必须包含至少一列不是外部引用错误”

Question

由于 SSRS 不允许对聚合进行过滤，因此我找到了一些代码来帮助我提出以下查询。但是，当我运行它时，我得到：

每个 GROUP BY 表达式必须包含至少一列不是外部引用

我到处搜索，但找不到解决方法。我什至从查询中删除了两个额外的表，所以根本没有连接。如果订单上的总行数小于 500 美元且大于 0，我不需要退回任何订单。

SELECT 
  tdsls041_sales_order_lines.company, 
  tdsls041_sales_order_lines.order_number,  
  tdsls041_sales_order_lines.amount, 
  tdsls041_sales_order_lines.item, 
  tdsls041_sales_order_lines.container
FROM
  tdsls041_sales_order_lines AS tdsls041_sales_order_lines 
WHERE
 (tdsls041_sales_order_lines.company = 610)  AND 
 (tdsls041_sales_order_lines.order_number IN
 (SELECT
    tdsls041_sales_order_lines.order_number
  FROM            
    tdsls041_sales_order_lines AS tdsls041_sales_order_lines_1
  GROUP BY 
    tdsls041_sales_order_lines.order_number
  HAVING  
    (SUM(tdsls041_sales_order_lines.amount) <= 500) OR
     SUM(tdsls041_sales_order_lines.amount) > 0))

SQL Server 抱怨的问题是 Grouping 需要在 SELECT 语句中使用聚合函数。不幸的是，您想使用 IN，您需要一个 订单号 列表。

您只需向子查询添加一个聚合函数，然后添加另一个层以从中仅选择订单号。

SELECT T1.company, T1.order_number,  T1.amount, T1.item, T1.container
FROM    tdsls041_sales_order_lines AS T1  
WHERE   (T1.company = 610) AND (T1.order_number IN
                    (SELECT order_number FROM 
                             (SELECT        TSOL.order_number, SUM(TSOL.amount) AS TTL
                               FROM            tdsls041_sales_order_lines AS TSOL
                               GROUP BY TSOL.order_number
                               HAVING (SUM(TSOL.amount) <= 500) OR
                                                   SUM(TSOL.amount) > 0) AS T2) )

您可以过滤图表和表格中的聚合。您必须将聚合过滤器放在您的 GROUP 而不是表本身上（Group Properties->Filters 选项卡）。
