参数说明
-------------------------------------------------------------
/**//*
@strTable --要显示的表或多个表的连接
@strField --要查询出的字段列表,*表示全部字段
@intTop --最多读取记录数
@pageSize --每页显示的记录个数
@pageIndex --要显示那一页的记录
@strWhere --查询条件,不需where
@strSortKey --用于排序的主键
@strSortField --用于排序，如：id desc (多个id desc,dt asc)
@strOrderBy --排序,0-顺序,1-倒序
@pageCount --查询结果分页后的总页数
@RecordCount --查询到的总记录数
@UsedTime --耗时测试时间差
