asp.net 数据访问层 存储过程分页语句

所以最好在数据访层分页,如果这样就要使用存储过程来分页.以下是以pubs 数据库中的employee表为例来进行数据分页的存储过程,你可以参考它根据实际情况来创建自己的存储过程.

注:@pageindex 数据页的索引,@dataperpage 每页的记录数目,@howmanyrecords 用来获取总的记录数.
复制代码 代码如下:
create proc getdata @pageindex int,@dataperpage int,@howmanyrecords int output
as
declare @temptable table
(
rowindex int,
emp_id char(9),
fname varchar(20),
minit char(1),
lname varchar(30)
)
insert into @temptable
select row_number() over(order by emp_id) as rowindex,emp_id,fname,minit,lname
from employee
select @howmanyrecords=count(rowindex) from @temptable
select * from @temptable
where rowindex>(@pageindex-1)*@dataperpage
and rowindex<=@pageindex*@dataperpage

declare @howmanyrecords int
exec getdata 2,5,@howmanyrecords output
select @howmanyrecords
declare @x int, @y int, @z int
select @x = 1, @y = 2, @z=3
select @x,@y,@z

create proc getdata2 @pageindex int,@dataperpage int,@howmanyrecords int output
as
declare @temptable table
(
rowindex int,
emp_id char(9),
fname varchar(20),
minit char(1),
lname varchar(30)
)
insert into @temptable
select row_number() over(order by emp_id) as rowindex,emp_id,fname,minit,lname
from employee
select @howmanyrecords=count(rowindex) from @temptable
select * from @temptable
where rowindex>(@pageindex-1)*@dataperpage
and rowindex<=@pageindex*@dataperpage

其中Row_number 函数可以给检索来的每条记录按照排序来编号.

接下来你就可以在asp.net 网页后台代码中调用该存储过程,就可以获取想要的数据.
