The Job history records of SQL Server are saved in msdb database, which is convenient to query the related Job definitions, plans and history records, while the events of MySQL have no history records. In order to check whether the event executes normally and the execution results, the following two steps are used to implement similar functions.
 
Realization
1. Create the event execution history table in mysql database 
CREATE TABLE `mysql`.`udf_event_history` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`event_gid` varchar(36) NOT NULL,
`db_name` varchar(128) NOT NULL DEFAULT '',
`event_name` varchar(128) NOT NULL DEFAULT '',
`start_time` datetime(3) NOT NULL DEFAULT current_timestamp(),
`end_time` datetime(3) DEFAULT NULL,
`is_success` tinyint(4) DEFAULT 0,
`duration` decimal(15,3) DEFAULT NULL,
`error_msg` varchar(512) DEFAULT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `idx_event_git` (`event_gid`),
KEY `idx_db_event_name` (`db_name`,`event_name`),
KEY `idx_s_e_time` (`start_time`,`end_time`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

 

2. Create an event according to the following template

Please pay attention to modify the relevant information according to the actual situation 
USE db1;

CREATE DEFINER=`root`@`localhost` EVENT `event_test1` 
ON SCHEDULE EVERY 1 MINUTE STARTS '2019-01-01 00:00:00' 
ON COMPLETION PRESERVE ENABLE DO 
BEGIN  
    DECLARE r_code CHAR(5) DEFAULT '00000';  
    DECLARE r_msg TEXT;  
    DECLARE v_error INT;  
    DECLARE v_start_time DATETIME(3) DEFAULT NOW(3);
    DECLARE v_event_gid VARCHAR(36) DEFAULT UPPER(REPLACE(UUID(),'-',''));  
    
    /*Change to the actual event name*/
    INSERT INTO mysql.udf_event_history (db_name, event_name, start_time, event_gid)  
    VALUES(DATABASE(), 'event_test1', v_start_time, v_event_gid);    
      
    BEGIN     
        DECLARE CONTINUE HANDLER FOR SQLEXCEPTION    
        BEGIN  
            SET  v_error = 1;  
            GET DIAGNOSTICS CONDITION 1 r_code = RETURNED_SQLSTATE, r_msg = MESSAGE_TEXT;  
        END;  
        /*The actual execution of a statement or stored procedure, etc*/
        CALL db1.usp_1();
    END;  
      
    UPDATE mysql.udf_event_history 
    SET end_time = NOW(3), is_success = ISNULL(v_error), duration = TIMESTAMPDIFF(microsecond,start_time, NOW(3)) / 1000000, 
    error_msg = CONCAT('error = ', r_code,', message = ', r_msg)
    WHERE event_gid = v_event_gid;  
      
END$$  
DELIMITER ;

 

By querying mysql.udf ﹣ event ﹣ history table, you can know the start and end time, success, execution time, error information of event, etc., which provides convenience for managing daily scheduling plans.
