Question

希望每个人都很好。

我正在尝试将数据从一个表格移动到另一个表格，但我得到了以下错误，这实际上让我感到疯狂，因为我无法看到它为什么不能工作的任何逻辑原因 - 事实上，我在过去运行相同的查询完全没问题！

错误1442（HY000）：无法更新表格＆＃39; bb_events＆＃39;在存储的函数/触发器中，因为它已被调用此存储函数/触发器的语句使用。

我正在运行的查询是：

INSERT INTO `bb_events` (
    `account_id`, 
    `device_id`, 
    `timestamp`, 
    `status_code`, 
    `latitude`, 
    `longitude`, 
    `speed`, 
    `heading`, 
    `odometer`, 
    `address`, 
    `street`, 
    `city`, 
    `state`, 
    `postcode`, 
    `country`, 
    `geozone_id`, 
    `battery_volts`, 
    `driver_id`, 
    `engine_time`, 
    `idle_time`, 
    `work_time`) 
SELECT 
    `accountID` AS `account_id`, 
    `deviceID` AS `device_id`, 
    `timestamp` AS `timestamp`,
    `statusCode` AS `status_code`, 
    `latitude`,
    `longitude`,
    `speedKPH`*0.621371192 AS `speed`,
    `heading`,
    `odometerKM`*0.621371192 AS `odometer`, 
    `address`,
    `streetAddress` AS `street`,
    `city`, 
    `stateProvince` AS `state`,
    `postalCode` AS `postcode`, 
    `country`,
    `geozoneID` AS `geozone_id`,
    `batteryVolts` AS `battery_volts`,
    `driverID` AS `driver_id`,
    `engineHours`*3600 AS `engine_time`,
    `idleHours`*3600 AS `idle_time`,
    `workHours`*3600 AS `work_time` 
FROM 
    `EventData`;

在bb_events表格中，我有一个触发设置，如下所示： -

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;
$$

我尝试在插入之前运行此触发器，这也没有用。当然，这必须是一个简单的解决方案：S。

提前致谢，
