的Oracle SQL触发错误：ORA-00933

Question

所以我想创建一个改变记录时间戳的触发，我有这个迄今为止

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; 

这里是错误的描述： 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与第一个BEGIN语句相关。这只影响数据库触发器的编译。 PL/SQL：SQL语句忽略

通过它的声音，它不认为我的if语句已经关好，但我不知道在哪里，我出了错

Answer 1

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; 

即有一个逗号而不是第二个SET关键字。

当你修改在触发器定义的表格上，您需要在更新触发器之前的。所以，这样的事情：

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;
