[COMMENT 'comment']

建立表 CREATE TABLE test(endtime DATETIME);

建立存儲過程test
DROP PROCEDURE IF EXISTS test;
CREATE PROCEDURE test ()
BEGIN
/*update examinfo SET endtime = now() WHERE id = 14; */
INSERT INTO test(endtime) VALUE (NOW());
END ;

建立event e_test
DROP EVENT IF EXISTS e_test;
CREATE EVENT if not exists e_test
on schedule every 3 second  
on completion preserve
do call test();
每隔30秒將執行存儲過程test,將當前時間更新到examinfo表中id=14的記錄的endtime字段中去

4.event的時間設置
設置event很簡單，可是麻煩的是如何設置執行的時間，網上找了一些，本身總結了一下。
先看語句，以下面這個
     CREATE EVENT test_event ON SCHEDULE EVERY 1 DAY STARTS '2012-09-24 00:00:00'
     ON COMPLETION PRESERVE ENABLE DO CALL test_procedure();
EVERY 後面的是時間間隔，能夠選 1 second，3 minute，5 hour，9 day，1 month，1 quarter（季度），1 year
從2013年1月13號0點開始，天天運行一次
ON SCHEDULE EVERY 1 DAY STARTS '2013-01-13 00:00:00'
從如今開始每隔九天定時執行
ON SCHEDULE EVERY 9 DAY STARTS NOW() ；
每一個月的一號凌晨1 點執行
on schedule every 1 month starts date_add(date_add(date_sub(curdate(),interval day(curdate())-1 day),interval 1 month),interval 1 hour);
每一個季度一號的凌晨1點執行
on schedule every 1 quarter starts date_add(date_add(date(concat(year(curdate()),'-',elt(quarter(curdate()),1,4,7,10),'-',1)),interval 1 quarter),interval 1 hour);
每一年1月1號凌晨1點執行
on schedule every 1 quarter starts date_add(date_add(date(concat(year(curdate()),'-',elt(quarter(curdate()),1,4,7,10),'-',1)),interval 1 quarter),interval 1 hour);
