的Oracle SQL觸發錯誤：ORA-00933

Question

所以我想創建一個改變記錄時間戳的觸發，我有這個迄今爲止

create or replace TRIGGER job_date_set 
     AFTER INSERT OR UPDATE OF start_date, closing_date ON jobs 
     FOR EACH ROW 
    BEGIN 
     IF UPDATING THEN 
     CASE 
      WHEN :OLD.closing_date != :NEW.closing_date THEN 
      UPDATE jobs 
      SET closing_date = to_date(to_date(:NEW.closing_date,'DD/MON/YYYY')||' 23:59:59','DD/MON/YYYY HH24:MI:SS') 
      WHERE :OLD.job_id = job_id; 
      WHEN :OLD.start_date != :NEW.start_date THEN 
      UPDATE jobs 
      SET start_date = to_date(to_date(:NEW.start_date,'DD/MON/YYYY') ||' 00:00:00','DD/MON/YYYY HH24:MI:SS') 
      WHERE :OLD.job_id = job_id; 
     END CASE; 
     END IF; 
     IF INSERTING THEN 
     UPDATE jobs 
     SET closing_date = to_date(to_date(:NEW.closing_date,'DD/MON/YYYY') ||' 23:59:59','DD/MON/YYYY HH24:MI:SS') 
     SET start_date = to_date(to_date(:NEW.start_date,'DD/MON/YYYY')||' 00:00:00','DD/MON/YYYY HH24:MI:SS') 
     WHERE :OLD.job_id = job_id; 
     END IF; 
    END; 

這裏是錯誤的描述： 編譯失敗，第17行（16:54:27）與編譯錯誤關聯的行號與第一個BEGIN語句相關。這隻影響數據庫觸發器的編譯。 PL/SQL：ORA-00933：SQL命令未正確結束編譯失敗，第15行（16:54:27）與編譯錯誤關聯的行號與第一個BEGIN語句相關。這隻影響數據庫觸發器的編譯。 PL/SQL：SQL語句忽略

通過它的聲音，它不認爲我的if語句已經關好，但我不知道在哪裏，我出了錯

相反的：

UPDATE jobs 
    SET closing_date = to_date(to_date(:NEW.closing_date,'DD/MON/YYYY') ||' 23:59:59','DD/MON/YYYY HH24:MI:SS') 
    SET start_date = to_date(to_date(:NEW.start_date,'DD/MON/YYYY')||' 00:00:00','DD/MON/YYYY HH24:MI:SS') 
    WHERE :OLD.job_id = job_id; 

是：

UPDATE jobs 
    SET closing_date = to_date(to_date(:NEW.closing_date,'DD/MON/YYYY') ||' 23:59:59','DD/MON/YYYY HH24:MI:SS'), 
     start_date = to_date(to_date(:NEW.start_date,'DD/MON/YYYY')||' 00:00:00','DD/MON/YYYY HH24:MI:SS') 
    WHERE :OLD.job_id = job_id; 

即有一個逗號而不是第二個SET關鍵字。

當你修改在觸發器定義的表格上，您需要在更新觸發器之前的。所以，這樣的事情：

create or replace TRIGGER job_date_set 
    BEFORE INSERT OR UPDATE OF start_date, closing_date ON jobs 
    FOR EACH ROW 
BEGIN 
    IF UPDATING THEN 
    CASE 
     WHEN :OLD.closing_date <> :NEW.closing_date THEN 
     SELECT to_date(to_date(:NEW.closing_date,'DD/MON/YYYY')||' 23:59:59','DD/MON/YYYY HH24:MI:SS') 
     INTO :NEW.closing_date 
     FROM dual; 
     WHEN :OLD.start_date <> :NEW.start_date THEN 
     SELECT to_date(to_date(:NEW.start_date,'DD/MON/YYYY') ||' 00:00:00','DD/MON/YYYY HH24:MI:SS') 
     INTO :NEW.start_date 
     FROM dual; 
    END CASE; 
    END IF; 
    IF INSERTING THEN 
    SELECT to_date(to_date(:NEW.closing_date,'DD/MON/YYYY') ||' 23:59:59','DD/MON/YYYY HH24:MI:SS'), 
      to_date(to_date(:NEW.start_date,'DD/MON/YYYY')||' 00:00:00','DD/MON/YYYY HH24:MI:SS') 
    INTO :NEW.closing_date, :NEW.start_date; 
    END IF; 
END;
