ALTER PROCEDURE [dbo].[Proc_GetDataPaged]
-- Add the parameters for the stored procedure here
@StrSelect varchar(max)=null, --欲显示的列（多列用逗号分开），例如：id,name
@StrFrom varchar(max)= null, --表名称，或者是表连接字符串，多表连接例如:student as s inner join dwinfo as dw on s.dwbh=dw.bh
@StrWhere varchar(max)=null, --查询条件,''代表没有条件，单条件或者多条件，多条件例如：name='啊' and id=10
@StrOrder varchar(max) =null, --排序列(多个排序列用逗号分开），例如:id desc,name as
--@PageCount int output, --总页数
@ItemCount bigint output, --总记录数
@PageSize int =50, --每页显示条数
@BeginIndex int=1,--记录开始数
@DoCount bit =0 --是否统计总数，为0不统计，为1统计
-- @PageIndex int =1 --当前页
--@ClassCode char(10) =null, --单位编号（班级编号）
