分页

方式一

select top @pageSize * from company where id not in

(select top @pageSize*(@pageIndex-1) id from company)

 

方式二ROW_NUMBER()OVER

 

--ROW_NUMBER() 就是生成一个有顺序的行号,而他生成顺序的标准,就是后面紧跟的OVER(ORDER BY ID)

--还必须添加OVER语句以便告诉SQL Server你希望怎样添加行序号。

select getdate()

select * from company where id in (

--搜索出settable表中所有的编号，也就是company表中的id，这里只不过要得到num（即有顺序的编号）

select id from

--搜索出出表中的所有的id，并且新建一列num用来存取排序的编号，并且把这张表赋值给settable

(select id,row_number() over (order by id) as

num from company)

as settable

--添加搜索条件页索引和页大小

where num between (@pageIndex-1)*@pageSize+1 and @pageIndex*@pageSize)

select getdate()

 

方式三

SELECT * FROM (SELECT ROW_NUMBER() OVER(ORDER BY id asc) AS rownum,

id

FROM company ) AS D

WHERE rownum BETWEEN (@pageIndex-1)*@pageSize+1 AND @pageIndex*@pageSize

ORDER BY id asc
