Microsoft Access：在分组查询中添加项目？

Question

查询我是从这样看起来分组..

FirstName|LastName|SSN|CheckNo|CheckDate|CheckAmt|Description|
Stone    |Striclan|271-1397543|131292223|-2000.78|FICA       |
Stone    |Striclan|271-1397543|131292223|-2000.78|FICA       |
Stone    |Striclan|271-1397543|131292223|20000.78|Cost of Lab|

尝试创建分组查询...

FirstName|LastName|Description|Sum of Payment Types
Stone    |Striclan|FICA       |-4001.56
Stone    |Striclan|Cost of Lab|20000.78

查询按描述进行分组，并使用checkAmt描述的总和。我似乎无法弄清楚如何创建付款类型总和部分，非常感谢任何和所有帮助。

Answer 1

您可以尝试这种方式：

SELECT FirstName, LastName, Description, SUM(CheckAmt) As 'Sum of Payment Types'
FROM MyTable
GROUP BY FirstName, LastName, Description
