1.創(chuàng)建一個測試表 CREATE TABLE aaa (timeline TIMESTAMP); 2.創(chuàng)建一個事件:每秒插入一條記錄到數(shù)據(jù)表 CREATE EVENT e_test_insert ON SCHEDULE EVERY 1 SECOND DO INSERT INTO aaa VALUES (CURRENT_TIMESTAMP); 3.每天定時清空aaa表: -- 每天定時情況aaa表 CREATE EVENT e_test on schedule every 1 DAY starts timestamp '2016-12-19 12:00:00' do truncate table aaa; 4.每天定時情況aaa表,,5天后停止執(zhí)行 -- 每天定時情況aaa表,,5天后停止執(zhí)行 drop event if exists e_test; create event e_test on schedule every 1 day ends current_timestamp + INTERVAL 5 day do truncate table aaa; 5.5天后開啟每天定時清空test表,,一個月后停止執(zhí)行 -- 5天后開啟每天定時清空test表,一個月后停止執(zhí)行 CREATE EVENT e_test ON SCHEDULE EVERY 1 DAY STARTS CURRENT_TIMESTAMP + INTERVAL 5 DAY ENDS CURRENT_TIMESTAMP + INTERVAL 1 MONTH DO TRUNCATE TABLE aaa; |
