超级强大的 分页Sql存储过程

CREATE PROCEDURE [dbo].[GetPage]
 @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,null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
    @ItemCount bigint = 0 output,  --总记录数
    @PageSize int = 50,     --每页显示条数
 @PageIndex int = 1     --当前页
