场景1：主键在清空表之后不会回到1开始

ALTER TABLE T_GPS_UPLOAD ALTER COLUMN ID RESTART WITH 1

场景2：清空表中的所有内容，

TRUNCATE TABLE T_GPS_UPLOAD IMMEDIATE;

场景3：查询分页

select * from (
       select a.* , rownumber() over(order by id ) as rowid from (" +
       select * from T_VERSION where VERSION_NO  " +
       like ‘%‘ || #{versionNo} ||‘%‘ AND VERSION_TYPE like ‘%‘ || #{versionType} ||‘%‘)" +
        a) tmp where  tmp.rowid <= #{pageOneParam} and tmp.rowid > #{pageTwoParam}
