sql查询时加上行号
sql查询时加上行号
sql查询的时候有时候要加上行号,这里做个备忘~
1(建议采用),
select row_number() over (order by col1) as no,newid() as id,*
from Table1
order by col1
2,
select no=identity(int,1,1),newid() as id,*
into #temptable From Table1
order by col1
Select * From #temptable
Drop Table #temptable
3,
SELECT (SELECT sum(1) FROM Table1
WHERE col1 <= a.col1) AS no, *
FROM Table1 a
