怎样用select 实现查询出指定范围的数据
我的意思是:
通过存储过程实现,穿两个参数StartRecordIndex,PageSize过去,就
查询出StartRecordIndex至PageSize的纪录。
例如,在customer表中,StartRecordIndex=10,PageSize=10
运行这个select语句就可以查出cutomer中第10条到,第19条的纪录!
这样的select语句要怎么写?
------解决方案--------------------create procedure usp_getdata(@StartRecordIndex int ,@pagesize int)
as
begin
declare @sql varchar(8000)
select @sql=isnull(@sql, ' ')+ 'select top '+cast(@pagesize as varchar(20))+ ' * from customer where id not in(select top '+cast(@StartRecordIndex-1 as varchar(20))+ 'id from customer) '
exec(@sql)
end
------解决方案--------------------create proc search_data
(
@StartRecordIndex int ,
@pagesize int
)
as
set nocount on
declare @sql varchar(1000)
set @sql= ' '
select @sql=@sql+ 'select top '+cast(@pagesize as varchar(20))+ ' * from customer where id not in(select top '+cast(@StartRecordIndex-1 as varchar(20))+ 'id from customer) '
exec(@sql)
set nocount off
end
