Oracle SQL Trigger error: ORA-00933

Question

所以我正在尝试创建一个触发器来更改记录时间戳，到目前为止我已经有了这个

    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;

错误描述如下：编译失败，第 17 行 (16:54:27) 与编译错误关联的行号与第一个 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) 与编译错误关联的行号是相对于第一个 BEGIN 语句的。这只会影响数据库触发器的编译。 PL/SQL：SQL 语句被忽略

听起来好像我的 if 语句没有正确关闭，但我不知道哪里出错了

当您修改 table 触发器时，您需要 before 更新触发器。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;

Answer 2

而不是：

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

即有一个逗号而不是第二个 SET 关键字。
