各位高手,请协助一下,谢谢。
test表结构如下
id,shopID
44 1
45 3
49 4
50 8
53 4
如何写sql语句,才能在查询结果构造字段seq,使结果如下:
seq,id,shopID
1 44 1
2 45 3
3 49 4
4 50 8
5 53 4
谢谢了,各位
[解决办法]
select seq=row_number()over(order by getdate()),*from tb
[解决办法]
create sequence seq;select seq.nextval seq,id,shopID from test;
[解决办法]
select id=identity(int,1,1), id,shopID into #tb from testselect * from #tb
[解决办法]
--> 测试数据:[test]if object_id('[test]') is not null drop table [test]create table [test]([id] int,[shopID] int)insert [test]select 44,1 union allselect 45,3 union allselect 49,4 union allselect 50,8 union allselect 53,4select seq=(select COUNT(1) from test b where b.ID<=a.ID),* from test a/*seq id shopID---------------------1 44 12 45 33 49 44 50 85 53 4*/--在另外一个帖子已经恢复,没看见???
