                (EQP_ID, OP_ID, SV_RECORD, UPDATE_TIME)
                VALUES

                :OLD.OP_ID = :NEW.OP_ID,
                :OLD.UPDATE_TIME = :NEW.SYSTIMESTAMP;
    END IF;
END;

提前致谢。

您的更新有语法错误 statement.Also，REFERENCING NEW AS NEW OLD AS OLD 是不必要的。

在您的更新语句中，op_id 和 eqp_id 不应该在 where clause 而不是 SET 中吗？

CREATE OR REPLACE TRIGGER table_trg AFTER
     INSERT OR UPDATE ON table_a
     FOR EACH ROW
        BEGIN 
IF (:new.eqp_id <>:old.eqp_id AND :new.op_id <>:old.op_id ) THEN
     INSERT INTO table_b (
          eqp_id,
          op_id,
          sv_record,
          update_time
     ) VALUES (
          :new.eqp_id,
          :new.op_id,
          :new.sv_record,
          :new.update_time
     );
ELSE 
 UPDATE table_b
   SET sv_record = :new.sv_record,
    update_time  = systimestamp
 WHERE eqp_id    = :new.eqp_id   --change the columns in set and where appropriately.
   AND op_id     = :new.op_id,
     END IF;
end;
