存储过程：

create proc Test

@PageIndex INT,--@PageIndex从计数,0为第一页

@PageSize INT, --页面大小

@RecordCount INT OUT, --总记录数

@PageCount INT OUT--页数

as

SELECT @RecordCount = COUNT(*) FROM A --获取记录数 SET @PageCount = CEILING(@RecordCount * 1.0 / @PageSize) --计算页面数据

SELECT SerialNumber,Id,Names,Age FROM (SELECT Id,Names,Age,ROW_NUMBER() OVER (ORDER BY Id ) AS SerialNumber FROM A ) AS T

WHERE T.SerialNumber > (@PageIndex * @PageSize) and T.SerialNumber <= ((@PageIndex+1) * @PageSize)

go

存储过程测试：

DECLARE @RecordCount int ,@PageCount int exec Test 0,10, @RecordCount OUTPUT, @PageCount OUTPUT select @RecordCount,@PageCount go

存储过程的调用：

DBHelper类中的方法：

DBHelper类可能大家的都不同，可以根据自己的DBHelper类修改此方法。 在这里我也把自己用的DBHelper写出来（注重版权，本人只是交流需要，无其他商业目的）
