我有非常基本的查询，我想对S.No明智地进行一些分组，即
S.No ProductName Qty Price
1 IndoorUnit 1 200
2 outdoorUnit 1 300
3 IndoorUnit 1 400
4 outdoorUnit 1 500
5 IndoorUnit 1 900
6 outdoorUnit 1 300
现在我想要那样的团体
S.No ProductName Qty Price
1 IndoorUnit(completeSet) 1 500
2 indoorUnit(completeSet) 1 900
3 indoorUnit(completeSet) 1 1200
