所以我正在尝试创建一个更改记录时间戳的触发器，到目前为止我有这个

    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;

以下是错误的描述： 编译失败，第 17 行 (16:54:27) 与编译错误相关的行号与第一个 BEGIN 语句相关。这只会影响数据库触发器的编译。PL/SQL：ORA-00933：SQL 命令未正确结束编译失败，第 15 行 (16:54:27) 与编译错误相关的行号与第一个 BEGIN 语句相关。这只会影响数据库触发器的编译。PL/SQL：忽略 SQL 语句

听起来，它认为我的 if 语句没有正确关闭，但我不知道我哪里出错了

当您修改定义触发器的表时，您需要一个更新前触发器。所以，像这样：

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;

代替：

    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;

它的：

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

即有一个逗号而不是第二个SET关键字。
