  • Gridview各种功能+AspNetPager+Ajax实现无刷新存储过程分页 （留着用）

    存储过程：

    GetProductsCount1：

    GetProductsByPage：

    复制代码
    CREATE PROCEDURE GetProductsByPage
    @PageNumber     int    ,
    @PageSize     int
    AS
    declare @sql nvarchar(    4000    )
    set @sql ='select top '+ Convert(varchar, @PageSize) +' * from test where id not in (select top '+ Convert(varchar, (@PageNumber -1) * @PageSize) +' id from test)'
    exec sp_executesql @sql
    GO
    复制代码
