insert into ReRowTest values(2,4)
insert into ReRowTest values(2,4)
insert into ReRowTest values(3,5)
insert into ReRowTest values(3,5)

SQL语句：
Select Distinct * into #tempTable From ReRowTest
Delete From ReRowTest
insert ReRowTest Select * From #tempTable
Drop table #tempTable
Select * From ReRowTest 结果为：
ID Name
1 3
2 4
3 5
如果常用可以封装成SQL存储过程
