DB2的 部分SQL语句

Posted 2020-12-18 HAC-John

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}
