is there a vba or setting way to achieve that ? 是否有VBA或设置方法来实现这一目标?
The proper way to do that is to use an aggregation function in your query, in your case it would be sum . 这样做的正确方法是在查询中使用聚合函数,在您的情况下为sum 。 Your query will look like this.
您的查询将如下所示。
SELECT Type, SUM(value) As Total FROM table GROUP BY Type;
if you use the graphical query builder then you will have to follow this 如果你使用图形查询生成器,那么你将不得不遵循这个
