Question

所以我试图创建一个改变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

听到它的声音，它并不认为我的if语句已被正确关闭，但我不知道我哪里出错了

当您修改表时，触发器已定义，您需要之前的更新触发器。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;

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;

它是：

    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。
