如何对计算字段求和
我想在这里问一个我认为对某些人来说很容易的问题。
好的，我有一个查询返回两个相关表的记录。 （一对多）
在此查询中，我有大约 3 到 4 个基于 2 个表中的字段的计算字段。
现在我想要一个用于名称的 group by 子句和一个 sum 子句来对计算字段求和，但最终会出现错误消息：
“您试图执行不属于聚合函数的查询”
所以我决定只运行没有总计的查询 *（即没有 group by 、 sum 等,,,） : 然后我创建了另一个查询来汇总我之前的查询。 （即使用 group by 子句表示名称，使用 sum 表示计算字段……这里没有计算）这很好（我过去常常这样做），但我不喜欢仅仅为了获得汇总总数而进行两个查询。他们是否有其他方式在设计视图中执行此操作并仅创建一个查询？ 我将非常感激。
谢谢：

I‘d like to ask I question that here that I think would be easy to some people.
Ok I have query that return records of two related tables. (One to many)
In this query I have about 3 to 4 calculated fields that are based on the fields from the 2 tables.
Now I want to have a group by clause for names and sum clause to sum the calculated fields but it ends up in error message saying:
“You tried to execute a query that is not part of aggregate function”
So I decided to just run the query without the totals *(ie no group by , sum etc,,,)
:
And then I created another query that totals my previous query. ( i.e. using group by clause for names and sum for calculated fields… no calculation here) This is fine ( I use to do this) but I don’t like having two queries just to get summary total. Is their any other way of doing this in the design view and create only one query?.
I would very much appreciate.
Thankyou:
JM

听起来查询认为计算字段需要成为分组或其他内容的一部分。您可能需要研究子查询。
你能发布sql（之前和之后）吗？这将有助于了解问题所在。
Sounds like the query is thinking the calculated fields need to be part of the grouping or something. You might need to look into sub-querying.
Can you post the sql (before and after). It would help in getting an understanding of what the issue is.
