mysql-定时调用存储过程

mysql定时调用存储过程，对表数据集表结构进行备份

存储过程实例：

BEGIN
	DECLARE tname varchar(64);	
	set @tname = CONCAT('RENAME TABLE sms_accpet TO sms_accpet',DATE_FORMAT(NOW(),'%Y%m'));	
	PREPARE pre_tname from @tname;
	EXECUTE pre_tname;

	set @newtable = CONCAT('create table sms_accpet select * from sms_accpet_template where 1=2');
	PREPARE pre_newtable from @newtable;
	EXECUTE pre_newtable;
	
	alter table sms_accpet add primary key (id);
	alter table sms_accpet modify column id int unsigned not null auto_increment;
END

定时器实例

CREATE EVENT EVENT_SMS    
ON SCHEDULE EVERY 1 MONTH STARTS DATE_ADD(DATE_ADD(DATE_SUB(CURDATE(),INTERVAL DAY(CURDATE())-1 DAY), INTERVAL 1 MONTH),INTERVAL 1 HOUR)  
ON COMPLETION PRESERVE ENABLE  
DO CALL backUpSms();

1.复制表结构及数据到新表

CREATE TABLE 新表
SELECT * FROM 旧表

2.仅仅复制表结构到新表

CREATE TABLE 新表
SELECT * FROM 旧表 WHERE 1=2
即:让WHERE条件不成立.
方法二:(低版本号的mysql不支持，mysql4.0.25 不支持，mysql5已经支持了)
CREATE TABLE 新表
LIKE 旧表

3.复制旧表的数据到新表(如果两个表结构一样)

INSERT INTO 新表
SELECT * FROM 旧表

4.复制旧表的数据到新表(如果两个表结构不一样)

INSERT INTO 新表(字段1,字段2,…….)
SELECT 字段1,字段2,…… FROM 旧表
