规范通用分页存储过程，通用性极强！
昨天写存储过程时遇到一个麻烦，再搜寻答案时搜到了“通用存储过程”，但只看到部分残缺代码，多方参考后，鄙人对其进行总结规范，得出以下规范存储过程，竟然把本人项目里50多个查询存储过程代替！不敢独享，遂贴出与大家分享，希望对大家有所帮助！！
该存储过程几乎可以涵盖所有查询存储过程（目前本人还没有发现不能使用的）
参数：分页大小，第几页，需要得到的字段 ，需要查询的表 ， 查询条件，排序的字段名，排序的类型，主键名称
输入参数即可查询，无论是查询一条记录还是查询多条记录，无论是分页还是不分页，无论是需要查询条件还是不需要查询条件……，都可使用此通用的存储过程！！！
通用性相当好！！

既然是带条件的，在里面内查询时也应该带上这个条件
