简单的总和和组

Question

我有一个表有2个简单的字段:RoomNumber和RoomEarned

我想将具有多个RoomEarned值的房间组合在一起并将它们的总和相结合.基本上将值一起添加到内联中.

基本上制作这张桌子..

RoomNumber | RoomEarned
1 | 13.23
2 | 23.79
3 | 50.75
4 | 32.90
10 | 11.31
11 | 31.83
12 | 13.92
12 | 18.82
13 | 41.87
14 | 87.74
15 | 100.83

进入这...

RoomNumber | RoomEarned
1 | 13.23
2 | 23.79
3 | 50.75
4 | 32.90
10 | 11.31
11 | 31.83
12 | 32.74
13 | 41.87
14 | 87.74
15 | 100.83

显然它是一个分组功能,但是我的能力......我非常短暂.

有任何想法吗？
