求答案:数据分组显示,增加递增编号
数据如下:
NO 顺序
000000000001 1
000000000002 1
000000000003 1
010000000001 5
010000000001 4
010000000001 2
010000000001 1
010000000002 4
010000000002 3
010000000002 2
010000000002 1
想得到的结果:
NO 顺序 编号
000000000001 1 1
000000000002 1 1
000000000003 1 1
010000000001 5 1
010000000001 4 2
010000000001 2 3
010000000001 1 4
010000000002 4 1
010000000002 3 2
010000000002 2 3
010000000002 1 4
有一点点思路,可是不能实现,请各位帮忙看看,谢谢。
[解决办法]
SELECT *,编号=(SELECT COUNT(*) FROM TB WHERE NO=T.NO AND 顺序<=T.顺序) FROM TB T
[解决办法]
select *,编号=row_number over(partition by NO order by 顺序) from tb
[解决办法]
--sql 2000select * , 编号 = (select count(1) from tb where NO = t.NO and 顺序 < t.顺序) + 1 from tb t--sql 2005select * , 编号 = row_number() over(partition by NO order by 顺序) from tb
