MySQL - 创建触发器错误 1064( 'DELIMITER ; ' 附近)

Question

希望大家一切都好。

我正在尝试创建一个 mysql 触发器，但是我不断收到以下错误:

[Err] 1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DELIMITER' at line 1 [Err] DELIMITER ;

我的代码如下(请注意，实际文件有 130 行长，我刚刚包含了问题所在的部分，或者至少我相信是这样)。

/* BB Events Insert After Trigger */
DELIMITER $$
CREATE TRIGGER `event_insert_after` AFTER INSERT ON `bb_events`
FOR EACH ROW 
BEGIN 
    UPDATE `bb_device` SET `latitude` = NEW.`latitude`, `longitude` = NEW.`longitude`, `status_code` = NEW.`status_code`, `timestamp` = NEW.`timestamp`, `speed` = NEW.`speed`, `driver_id` = NEW.`driver_id`, `heading` = NEW.`heading` WHERE `account_id` = NEW.`account_id` AND `device_id` = NEW.`device_id`;
    IF NEW.`status_code` = 62465 THEN 
        INSERT INTO `bb_journey` (`account_id`, `device_id`, `start_timestamp`, `start_street`, `start_city`, `start_state`, `start_country`, `start_latitude`, `start_longitude`, `start_geozone`, `start_odometer`) VALUES (NEW.`account_id`, NEW.`device_id`, NEW.`timestamp`, NEW.`street`, NEW.`city`, NEW.`state`, NEW.`country`, NEW.`latitude`, NEW.`longitude`, NEW.`geozone_id`, NEW.`odometer`);
        UPDATE `bb_device` SET `current_journey` = (SELECT `id` FROM `bb_journey` WHERE `account_id` = NEW.`account_id` AND `device_id` = NEW.`device_id` ORDER BY `id` DESC LIMIT 1)  WHERE `account_id` = NEW.`account_id` AND `device_id` = NEW.`device_id`;
    END IF; 
    IF NEW.`status_code` = 62467 THEN 
        UPDATE `bb_journey` SET `end_timestamp` = NEW.`timestamp`, `end_street` = NEW.`street`, `end_city` = NEW.`city`, `end_state` = NEW.`state`, `end_country` = NEW.`country`, `end_latitude` = NEW.`latitude`, `end_longitude` = NEW.`longitude`, `end_geozone` = NEW.`geozone_id`, `end_odometer` = NEW.`odometer` WHERE `id` = (SELECT `current_journey` FROM `bb_device` WHERE `account_id` = NEW.`account_id` AND `device_id` = NEW.`device_id` ORDER BY `id` DESC LIMIT 1);
        UPDATE `bb_device` SET `current_journey` = '' WHERE `account_id` = NEW.`account_id` AND `device_id` = NEW.`device_id`;
    END IF;
END;$$
DELIMITER ;


/* BB Journey Update After Trigger */
DELIMITER $$
CREATE TRIGGER `journey_update_before` BEFORE UPDATE ON `bb_journey`
FOR EACH ROW 
BEGIN 
    IF NEW.`complete` <> 1 THEN 
        SET NEW.`distance` = ROUND(NEW.`end_odometer`-NEW.`start_odometer`,2);
        SET NEW.`duration` = SEC_TO_TIME(NEW.`end_timestamp`-NEW.`start_timestamp`);
    END IF;
    IF NEW.`complete` = 1 THEN 
        UPDATE `bb_events` SET `journey_id` = NEW.`id` WHERE `timestamp` BETWEEN NEW.`start_timestamp` AND NEW.`end_timestamp`;
    END IF;
END;$$
DELIMITER ;

非常感谢任何帮助!

谢谢

我在查看 Mysql create trigger 1064 error 后发现了这一点

正确的代码如下:

/* BB Events Insert After Trigger */
DELIMITER $$
DROP TRIGGER /*!50032 IF EXISTS */ `event_insert_after` $$
CREATE TRIGGER `event_insert_after` AFTER INSERT ON `bb_events`
FOR EACH ROW 
BEGIN 
    UPDATE `bb_device` SET `latitude` = NEW.`latitude`, `longitude` = NEW.`longitude`, `status_code` = NEW.`status_code`, `timestamp` = NEW.`timestamp`, `speed` = NEW.`speed`, `driver_id` = NEW.`driver_id`, `heading` = NEW.`heading` WHERE `account_id` = NEW.`account_id` AND `device_id` = NEW.`device_id`;
    IF NEW.`status_code` = 62465 THEN 
        INSERT INTO `bb_journey` (`account_id`, `device_id`, `start_timestamp`, `start_street`, `start_city`, `start_state`, `start_country`, `start_latitude`, `start_longitude`, `start_geozone`, `start_odometer`) VALUES (NEW.`account_id`, NEW.`device_id`, NEW.`timestamp`, NEW.`street`, NEW.`city`, NEW.`state`, NEW.`country`, NEW.`latitude`, NEW.`longitude`, NEW.`geozone_id`, NEW.`odometer`);
        UPDATE `bb_device` SET `current_journey` = (SELECT `id` FROM `bb_journey` WHERE `account_id` = NEW.`account_id` AND `device_id` = NEW.`device_id` ORDER BY `id` DESC LIMIT 1)  WHERE `account_id` = NEW.`account_id` AND `device_id` = NEW.`device_id`;
    END IF; 
    IF NEW.`status_code` = 62467 THEN 
        UPDATE `bb_journey` SET `end_timestamp` = NEW.`timestamp`, `end_street` = NEW.`street`, `end_city` = NEW.`city`, `end_state` = NEW.`state`, `end_country` = NEW.`country`, `end_latitude` = NEW.`latitude`, `end_longitude` = NEW.`longitude`, `end_geozone` = NEW.`geozone_id`, `end_odometer` = NEW.`odometer` WHERE `id` = (SELECT `current_journey` FROM `bb_device` WHERE `account_id` = NEW.`account_id` AND `device_id` = NEW.`device_id` ORDER BY `id` DESC LIMIT 1);
        UPDATE `bb_device` SET `current_journey` = '' WHERE `account_id` = NEW.`account_id` AND `device_id` = NEW.`device_id`;
    END IF;
END;
$$


/* BB Journey Update After Trigger */
DELIMITER $$
DROP TRIGGER /*!50032 IF EXISTS */ `journey_update_before` $$
CREATE TRIGGER `journey_update_before` BEFORE UPDATE ON `bb_journey`
FOR EACH ROW 
BEGIN 
    IF NEW.`complete` <> 1 THEN 
        SET NEW.`distance` = ROUND(NEW.`end_odometer`-NEW.`start_odometer`,2);
        SET NEW.`duration` = SEC_TO_TIME(NEW.`end_timestamp`-NEW.`start_timestamp`);
    END IF;
    IF NEW.`complete` = 1 THEN 
        UPDATE `bb_events` SET `journey_id` = NEW.`id` WHERE `timestamp` BETWEEN NEW.`start_timestamp` AND NEW.`end_timestamp`;
    END IF;
END;
$$

我不知道这是如何运作的，但确实如此。 MySQL 版本 5.5，CentOS 6 64 位。

谢谢大家:-)
