CREATE PROCEDURE CN5135_SP_Pagination
/******************************************************************
千万数目级分页存储过程
*******************************************************************
参数阐明:
1.Tables :表名称,视图
2.PrimaryKey :重要害字
3.Sort :排序语句，不带Order By 比如：NewsID Desc,OrderRows Asc
4.CurrentPage :当前页码
5.PageSize :分页尺寸
6.Filter :过滤语句，不带Where
7.Group :Group语句,不带Group By
后果演示：http://www.cn5135.com/_App/Opportunities/QueryResult.aspx
