我有一个表tbl，有3个字段
auno int
type int
stat varchar
现在表中数据是这样的：
auno type stat
2659 807 TYPE
2658 805 CHIPSET
2655 806 TYPE
2661 808 CHIPSET
2654 802 WxHxD(mm)
2741 804 Weight(Kg/Pound)
我想要实现这种效果：当stat中内容跟前面有重复时， stat内容的后面加1
我想要得到这种查询结果：
auno type stat
2659 807 TYPE
2658 805 CHIPSET
2655 806 TYPE1
2661 808 CHIPSET1
2654 802 WxHxD(mm)
2741 804 Weight(Kg/Pound)
这样的sql语句怎么写啊？ 望大虾帮忙。。。
