DB2:FETCH FIRST 1 ROWS ONLY

DB2:FETCH FIRST  ROWS  ONLY，在Oracle中使用where rownum=1代替
DB2：
 SELECT INSTORAGENO  FROM
                               (
                               SELECT max(AUDITINGTIME) AUDITINGTIME ,INSTORAGENO  FROM T_IN_STOREROOM
                               order by AUDITINGTIME desc
                               FETCH FIRST  ROWS  ONLY
                               ) a
Oracle：
SELECT INSTORAGENO  FROM
                        (
                        SELECT max(AUDITINGTIME) AUDITINGTIME ,INSTORAGENO  FROM T_IN_STOREROOM
                        order by AUDITINGTIME desc
                        ) a  where rownum=
