查询时加序号
a:没有主键的情形:
Select identity(int,1,1) as
iid,* into #tmp from TableName
Select * from #tmp
Drop
table #tmp
b:有主键的情形:
Select (Select sum(1) from
TableName where KeyField <= a.KeyField) as iid,* from
TableName a
eg:
select (select sum(1) from user_Admin where
id<=a.id) as ID,id,displayName from user_Admin a order by a.ID asc
SELECT 序号= (SELECT COUNT(客户编号) FROM 客户 AS LiMing WHERE LiMing.客户编号<= Chang.客户编号), 客户编号, 公司名称 FROM 客户 AS Chang ORDER BY 1; GO
/* 方法二: 使用SQL Server 2005 独有的RANK() OVER () 语法*/ SELECT RANK() OVER (ORDER BY 客户编号 DESC) AS 序号, 客户编号, 公司名称 FROM 客户; GO
/* 方法三*/ SELECT 序号= COUNT(*), LiMing.客户编号, LiMing.公司名称 FROM 客户 AS LiMing, 客户AS Chang WHERE LiMing.客户编号>= Chang.客户编号 GROUP BY LiMing.客户编号, LiMing.公司名称 ORDER BY 序号; GO
/* 方法四 建立一个「自动编号」的字段,然后将数据新增至一个区域性暂存数据表, 然后由该区域性暂存数据表中,将数据选取出来,最后删除该区域性暂存数据表 */ SELECT 序号= IDENTITY(INT,1,1), 管道, 程序语言, 讲师, 资历 INTO #LiMing FROM 问券调查一; GO SELECT * FROM #LiMing; GO DROP TABLE #LiMing; GO
/* 方法五 使用 SQL Server 2005 独有的ROW_NUMBER() OVER () 语法 搭配 CTE (一般数据表表达式,就是 WITH 那段语法)选取序号2 ~ 4 的数据 */ WITH 排序后的图书 AS (SELECT ROW_NUMBER() OVER (ORDER BY 客户编号 DESC) AS 序号, 客户编号, 公司名称 FROM 客户) SELECT * FROM 排序后的图书 WHERE 序号 BETWEEN 2 AND 4; GO
------------分页使用---------------------------
SELECT RANK() OVER (ORDER BY id asc) AS no,* into #temp FROM Bbs_reply select * from #temp where no between 1 and 100 drop table #temp
