Answer 1

使用MySQL事件;确保MySQL以“--event-scheduler = ON”启动，或将“event-scheduler = ON”添加到my.cnf文件中。

添加所需任务的代码如下所示;

DELIMITER $$ 

CREATE 
    EVENT `backup_and_truncate` 
    ON SCHEDULE EVERY 1 WEEK STARTS '2000-01-01 00:00:00' 
    DO BEGIN 

     -- Export Data 
    SELECT * 
    FROM my_table 
    INTO OUTFILE '/tmp/my_table.csv' 
    FIELDS TERMINATED BY ',' 
    ENCLOSED BY '"' 
    LINES TERMINATED BY '\n'; 

     -- Truncate Table 
    TRUNCATE my_table; 

    END */$$ 

DELIMITER ;
