Question

我的存储过程中的插入查询未运行。没有错误，但Query无法插入记录。我可以知道这是什么问题吗？

    CREATE DEFINER=`root`@`localhost` PROCEDURE `trip`(IN trip INT, IN rate INT, IN remark VARCHAR(1000))
    BEGIN
        UPDATE booking SET STATUS = "2" WHERE TRIP= trip;   

        SELECT rate AS RATE, remark AS REMARK, t.DRIVER_ID = @driver_id FROM trip_offer t WHERE t.TRIP = trip;

        INSERT INTO rating(TRIP_ID, U_ID, RATE, REMARK, CRT_TMS) VALUES(trip, @driver_id, rate, remark, now());
    END

Answer 1

我怀疑你有几个问题。

一个明确的问题是MySQL无法区分变量（存储过程的参数）和列。您应始终使用变量前缀。其次，你要做的事情并不完全清楚。这是我最好的猜测：

DELIMITER $$

CREATE DEFINER=`root`@`localhost` PROCEDURE `trip`(
    IN p_trip INT,
    IN p_rate INT,
    IN p_remark VARCHAR(1000))
BEGIN
    UPDATE booking SET STATUS = "2" WHERE TRIP = v_trip;   

    INSERT INTO rating(TRIP_ID, U_ID, RATE, REMARK, CRT_TMS) 
        SELECT t.trip, t.driver_id, v_rate, v_remark, now()
        FROM trip_offer t
        WHERE t.TRIP = v_trip;
END;$$

DELIMITER $$

Answer 2

问题：

t.DRIVER_ID = @driver_id SELECT中的错误。
@driver_id似乎没有被定义。
