查看您的代碼，請閱讀。簡而言之，我想告訴trigger是table上的事件。它被創建爲自動插入/更新/刪除該表的列值。在你的情況下，你在表R_TRACKER上創建觸發器，然後再在inserting以下創建觸發器。這是錯誤的。看你如何做到這一點。

--Table 
CREATE TABLE R_TRACKER 
(
    PROJECT_ID   VARCHAR2 (50), 
    PRO_LOC   VARCHAR2 (50), 
    DESIGNATION  VARCHAR2 (50), 
    NO_OF_POSITION  VARCHAR2 (50), 
    VACANCY_SINCE  VARCHAR2 (50), 
    STATUS    VARCHAR2 (50), 
    REMARKS   VARCHAR2 (50), 
    UPLOAD    VARCHAR2 (50), 
    RECRUITMENT_TYPE VARCHAR2 (50), 
    APPROVAL   VARCHAR2 (50), 
    ACTION    VARCHAR2 (50) 
); 

--Trigger上表

CREATE OR REPLACE TRIGGER R_TRACKER_TRI 
    BEFORE INSERT ON R_TRACKER 
    FOR EACH ROW 
DECLARE 
    v_number VARCHAR2 (15); 
BEGIN 
    IF INSERTING 
    THEN 
     :NEW.PROJECT_ID := '1';--PROJECT_ID(1) -- This seems to be a function in your case; 
    --:NEW.PRO_CREATED := LOCALTIMESTAMP; 
    -- :NEW.PRO_CREATED_BY := NVL('APP_USER', USER); 

     IF :NEW.RECRUITMENT_TYPE = 'New' 
     THEN 
     SELECT ( 'NEW/' 
       || TO_CHAR (SYSDATE, 'YY') 
       || '/' 
       || (NVL (MAX (SUBSTRB (PROJECT_ID, 8)), 10000) + 1)) 
      INTO v_number 
      FROM R_TRACKER 
      WHERE SUBSTRB (PROJECT_ID, 1, 3) = 'NEW'; 

     :NEW.PROJECT_ID := v_number; 

     ELSIF :NEW.RECRUITMENT_TYPE = 'Replacement' 
     THEN 
     SELECT ( 'REP/' 
       || TO_CHAR (SYSDATE, 'YY') 
       || '/' 
       || (NVL (MAX (SUBSTRB (PROJECT_ID, 8)), 10000) + 1)) 
      INTO v_number 
      FROM R_TRACKER 
      WHERE SUBSTRB (PROJECT_ID, 1, 3) = 'REP'; 

     :NEW.PROJECT_ID := v_number; 
     END IF; 

    END IF; 
END;
