CREATE DEFINER=`root`@`localhost` PROCEDURE `update_scheduler_minmax`(
    IN minVolt DOUBLE,
    IN min_volt_time timestamp,
    IN branch int)
BEGIN
    UPDATE min_max SET 
        MIN_VOLT = minVolt,
        MIN_VOLT_TIME = min_volt_time        
        WHERE BRANCH = branch AND DEVICE_ID = 'XXXXXXXXXXXXXUID';
END

Answer 1

尝试：

DELIMITER $$

CREATE DEFINER=`root`@`localhost` PROCEDURE `update_scheduler_minmax`(
    IN `_minVolt` DOUBLE,
    IN `_min_volt_time` timestamp,
    IN `_branch` int)
BEGIN
    UPDATE `min_max`
    SET `MIN_VOLT` = `_minVolt`, `MIN_VOLT_TIME` = `_min_volt_time`       
    WHERE `BRANCH` = `_branch` AND `DEVICE_ID` = 'XXXXXXXXXXXXXUID';
END$$

DELIMITER ;
