请问这个分页存储过程怎么写，

[happyxzxin]

alter PROCEDURE [dbo].[GetsearchPage] 
@nPage int,---第几页
@Pnum int,--每页页数
@key nvarchar(100),
@f_allidnum nvarchar(100) output  --返回总页数
AS 
declare @sql nvarchar(3000),@c nvarchar(20)


	set @sql='WITH OrderedOrders AS
(SELECT  count(id),soft_names,addtime,softsize,soft_garde,system_set,downcount,
ROW_NUMBER() OVER (order by [id])as RowNumber FROM soft where  soft_names like ''%'+@key+'%'''+' )
SELECT id,soft_names,addtime,softsize,soft_garde ,system_set,downcount
FROM OrderedOrders 
WHERE RowNumber>'+cast((@nPage-1)*@Pnum as nvarchar(50))+' and RowNumber<='+cast(@nPage*@Pnum as nvarchar(50))

				
set @sql=@sql+' order by addtime desc'

set @sql=@sql+' select '+cast(@f_allidnum as nvarchar(20))+'=count(*) from OrderedOrders '
exec(@sql)

@f_allidnum总是null

分页存储过程··网上有好多··干嘛自己写···

[/Quote]就差怎么返回总页数了

[moeryang]

exec(@sql)
select @f_allidnum =count(*) from OrderedOrders；

[moeryang]

@f_allidnum 如果作为一个输出参数的话应该直接执行sql语句

[happyxzxin]

还是不行，还是null
