求一SQL语句，

求一SQL语句，在线等。。。。
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
2659807TYPE
2658805CHIPSET
2655806TYPE
2661808CHIPSET
2654802WxHxD(mm)
2741804Weight(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
2659807TYPE
2658805CHIPSET
2655806TYPE1
2661808CHIPSET1
2654802WxHxD(mm)
2741804Weight(Kg/Pound)

这样的sql语句怎么写啊？ 望大虾帮忙。。。
