SQL Server 得到行号的SQL
SQL Server 得到行号的SQL
使用临时表：
select id=identity(int,1,1),value into #temp from YourTable
select * from #temp
drop table #temp
取得第11到20行记录：
select IDENTITY(int, 1,1) AS ID_Num,* into #temp from 表
select * from #temp where ID_Num>10 and ID_Num<=20
或
SELECT Top @PageSize *
from T
WHERE SortField NOT IN (SELECT TOP @PageSize * @Pagei SortField
from T
ORDER BY SortField
)
ORDER BY SortField

应一个朋友的要求，贴上收藏的SQL常用分页的办法～～
表中主键必须为标识列，[ID] int IDENTITY (1,1)
1.分页方案一：(利用Not In和SELECT TOP分页)
语句形式：
SELECT TOP 页记录数量 *
from 表名
WHERE (ID NOT IN
(SELECT TOP (每页行数*(页数-1)) ID
from 表名
ORDER BY ......
Suppose we have a recursive hierarchy stored in a relational database and we want to write it to XML. This might be for a variety of reasons – e.g. as a pre-cached input to a UI control, to export to another system using a pre-defined format, etc.
In SQL Server 2000, in order to ......
