在asp.net 网页中如果在业务逻辑层分页在使用PagedDataSource对象,但如果数据记录过多,使用它会严重的损害来源gaodaima#com搞(代@码网应用程序的性能.
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.
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.
