查询在Access 2010

Question

与此查询

SELECT Year, Month, Customer, Cod_user, Int(Sum(hours)) AS hours 
FROM T_Att 
GROUP BY Year, Mounth, Customer, Cod_user 
HAVING (((Year)="2016") AND ((Month)="03") AND ((Customer)="CA")); 

我得到以下结果

如果您要添加的全球总和（总和）和关键，什么需要改变？

虽然我没有测试过，你应该能够只需添加一个字段：

这将增加所有时间所有年份，月份和客户。

SELECT  Year, 
      Month, 
      Customer, 
      Cod_user, 
      Int(Sum(hours)) AS lhours, 
      (
      SELECT SUM(hours) 
      FROM T_Att 
      ) AS GlobalTotal 
FROM  T_Att 
GROUP BY Year, Month, Customer, Cod_user 
HAVING  (((Year)="2016") AND ((Month)="03") AND ((Customer)="CA")); 

为了保持GlobalTotal至2016年3月使用：

SELECT  Year, 
      Month, 
      Customer, 
      Cod_user, 
      Int(Sum(hours)) AS lhours, 
      (
      SELECT SUM(hours) 
      FROM T_Att 
      WHERE Year = T1.Year AND Month = T1.Month 
      ) AS GlobalTotal 
FROM  T_Att T1 
GROUP BY Year, Month, Customer, Cod_user 
HAVING  (((Year)="2016") AND ((Month)="03") AND ((Customer)="CA")); 

注 - 我已经改名hours到lhours以避免循环引用。您还应该考虑将其重命名为year和month，因为这些关键字可能会导致问题。
此外，year和month会为数字而不是文本更好。
