如何用SELECT 来自动生成一列序号
如,有一表
select col1,col2 from tb1,
------------------
col1 col2
a adf
b asdfasa
c adsdf
d asd112
-----------------
想得到如下的结果，SQL 指令应如何写
t1 col1 col2
001 a adf
002 b asdfasa
003 c adsdf
004 d asd112


[解决办法]
select id=identity(int,1,1),col1,col2 into # from tb1
select * from #
[解决办法]
select id=right(identity(int,1,1)+10000,4),col1,col2 into # from tb1
select * from #
[解决办法]
2005用
SELECT ROW_NUMBER() OVER (order by col2 ) AS COL,col1,col2 from tb1
2000用
select col= identity(int,1,1),col1,col2 into # from tbl
select * from #
drop table #
[解决办法]
select id=identity(int,1,1),col1,col2 into # from tb1
select id=right(id+10000,4),col1,col2 from #
