SQL分页

 

--第一种分页(TOP方式)--

select * from T_Sys_User where User_Id in 

(select top 10 User_Id from T_Sys_User where User_Id not in

(select top (10*0) User_Id from T_Sys_User

order by User_LoginName asc) 

order by User_LoginName asc)

order by User_LoginName asc

View Code

 

--第二种分页（ROW_NUMBER方式）Linq转换后也是用的这种--

select * from (select ROW_NUMBER() over (order by User_LoginName) as row,* from T_Sys_User) as T where T.row between 1 and 10 order by User_LoginName

View Code

 

--第三种分页：CTE方式（common_table_expression，公用表表达式，SQL编写递归--

WITH UserEntity

AS ( SELECT TOP ( 10 * 2 )

ROW_NUMBER() OVER ( ORDER BY User_LoginName DESC ) AS rownum ,

*

FROM T_Sys_User order by User_LoginName

)

SELECT *

FROM UserEntity

WHERE UserEntity.rownum > ( 10 * ( 2 - 1 ) )

ORDER BY UserEntity.User_LoginName

View Code

 

--第四种分页：Fetch(SQL Server 2012及SQL Server 2014)--

SELECT * 

FROM T_Sys_User 

ORDER BY User_LoginName DESC 

OFFSET ( 10 * ( 1 - 1 )) ROWS 

FETCH NEXT 10 ROWS ONLY;

--第五种分页：分页存储过程--

------------------------------------

--用途：支持任意排序的分页存储过程 

--说明：
