Question

需要支持，

我在Access中有一张包含大量记录的表格我想运行一个可以缩短数据的查询。

示例：

Table name : Lux1

+-----------+--------+------+
|Invoice No.|Fee Type|Amount|
+-----------+--------+------+
|18903      |D&R     |30    |
+-----------+--------+------+
|18903      |D&R     |40    |
+-----------+--------+------+
|27035      |Others  |100   |
+-----------+--------+------+
|27035      |Others  |75    |
+-----------+--------+------+

预期表格:(根据费用类型标准合并发票字段）

+-----------+--------+------+
|Invoice No.|Fee Type|Amount|
+-----------+--------+------+
|18903      |D&R     |70    |
+-----------+--------+------+
|27035      |Others  |175   |
+-----------+--------+------+

有人可以通过SQL语句或任何其他方法帮助我实现这个目标吗？

Answer 1

select InvNo, FeeType, sum(Amount) as Amount
from MyTable
group by InvNo, FeeType

Answer 2

 INSERT NEWTABLE(InvoiceNo,FeeType,Amount)
 SELECT InvoiceNo,
        FeeType,
        SUM(Amount)
 FROM SourceTable
 GROUP BY InvoiceNo,
          FeeType

如何根据多个字段值组合行？
