Question

我正在进行联合查询，将两个不同查询的结果加在一起，这些查询为我提供了来自两个不同会计期间的数据，以获得滚动的12个月数字。我收到消息“您的查询不包含指定的表达式”Report_Header“作为聚合函数的一部分”。我已经读过该字段需要在最后包含在GROUP BY语句中，但是当我从任一查询或两个查询添加字段时如下所示，我仍然得到消息。救命？我不是程序员，我是Access用户，所以我需要简单请：）。

SELECT [JOIN_IB_FREIGHT&PURCHASES_ROLLING12_SUB].Report_Header,
       Sum([JOIN_IB_FREIGHT&PURCHASES_ROLLING12_SUB].SumOfCASES) AS CASES,
       Sum([JOIN_IB_FREIGHT&PURCHASES_ROLLING12_SUB].SumOfPurchases) AS PURCHASES
FROM [JOIN_IB_FREIGHT&PURCHASES_ROLLING12_SUB]

UNION ALL

SELECT [JOIN_IB_FREIGHT&PURCHASES_Rolling12_SUB2].Report_Header,
       Sum([JOIN_IB_FREIGHT&PURCHASES_Rolling12_SUB2].SumOfCASES) AS CASES,
       Sum([JOIN_IB_FREIGHT&PURCHASES_Rolling12_SUB2].SumOfPurchases) AS PURCHASES
FROM [JOIN_IB_FREIGHT&PURCHASES_Rolling12_SUB2]
GROUP BY [JOIN_IB_FREIGHT&PURCHASES_ROLLING12_SUB].Report_Header,
         [JOIN_IB_FREIGHT&PURCHASES_Rolling12_SUB2].Report_Header

谢谢！

Answer 1

将GROUP BY [JOIN_IB_FREIGHT&PURCHASES_ROLLING12_SUB].Report_Header放在第一个查询下而不是第二个查询。

Answer 2

您可以聚合两个子查询：

SELECT [JOIN_IB_FREIGHT&PURCHASES_ROLLING12_SUB].Report_Header,
       Sum([JOIN_IB_FREIGHT&PURCHASES_ROLLING12_SUB].SumOfCASES) AS CASES,
       Sum([JOIN_IB_FREIGHT&PURCHASES_ROLLING12_SUB].SumOfPurchases) AS PURCHASES
FROM [JOIN_IB_FREIGHT&PURCHASES_ROLLING12_SUB]
GROUP BY [JOIN_IB_FREIGHT&PURCHASES_Rolling12_SUB].Report_Header

UNION ALL

SELECT [JOIN_IB_FREIGHT&PURCHASES_Rolling12_SUB2].Report_Header,
       Sum([JOIN_IB_FREIGHT&PURCHASES_Rolling12_SUB2].SumOfCASES) AS CASES,
       Sum([JOIN_IB_FREIGHT&PURCHASES_Rolling12_SUB2].SumOfPurchases) AS PURCHASES
FROM [JOIN_IB_FREIGHT&PURCHASES_Rolling12_SUB2]
GROUP BY [JOIN_IB_FREIGHT&PURCHASES_Rolling12_SUB2].Report_Header;

这可能就是你想要的。但是，它不会将两个表中相同标题下的信息组合在一起。为此，最简单的方法可能是一种观点。

查询不包括指定的表达式作为UNION查询中的聚合函数的一部分
