Oracle不支持'更新..從.. join' sysntax。用戶[合併]（https://docs.oracle.com/cd/B28359_01/server.111/b28286/statements_9016.htm#SQLRF01606）。 –

嗨如何在oracle中執行此操作？ – user3789200

UPDATE T1 SET t1.GEN_DATE = t2.GEN_DATE FROM PM_ACTION_CALENDAR_PLAN_TAB T1 INNER JOIN GEN_DATEPREPARE2 T2 ON t1.PM_NO = t2.PM_NO AND t1.SEQ_NO = t2.SEQ_NO AND t1.PM_REVISION = t2.PM_REVISION; –

試試這個

UPDATE PM_ACTION_CALENDAR_PLAN_TAB t1 
     SET t1.GEN_DATE = (select t2.GEN_DATE 
          from GEN_DATEPREPARE2 t2 
          where t2.PM_NO = t1.PM_NO 
          AND t2.SEQ_NO = t1.SEQ_NO 
          AND t2.PM_REVISION = t1.PM_REVISION)
