ALTER PROCEDURE [dbo].[sp_Pager2005]

@strGetFields varchar(1000) = ‘*’, — 需要返回的列如：’xname,xdemo’
@strOrder varchar(255)=”, — 排序的字段名如：’order by id desc’
@strWhere varchar(1500) = ”, — 查询条件(注意:不要加where)如:’xname like ”%222name%”’
@pageIndex int = 1, — 页码如：2
@pageSize int = 20, — 每页记录数如：20
@recordCount int output, — 记录总数
@doCount bit=0 — 非0则统计,为0则不统计(统计会影响效率)

Student,Score,Class的形式。
