通用分页存储过程

以下通用分页存储过程是根据网上相关资料改写而成，支持各个字段的排序，并且优化了查询速度

create PROCEDURE [dbo].[Paging_RowCount]

调用示例：

declare @p12 int
--set @p12=5254
exec  Paging_RowCount 
'laysite','id','site_id','asc',5,10,'ltrim(lon)+''@''+ltrim(lat) as jw,id as
pk,city as ''县市'',antenna_bearing as ''方向角'',sitename as ''站名''','1=1','',@p12 output
select @p12
