mysql-定时调用存储过程_MySQL

存储过程实例：

CREATE PROCEDURE backUpSms()
BEGIN
	DECLARE tname varchar(64);	
	set @tname = CONCAT('sms_accpet',DATE_FORMAT(NOW(),'%Y%m'));	
	set @rname = CONCAT('create table ',@tname,' select * from sms_accpet');
	PREPARE create_table from @rname;
	EXECUTE create_table;

	delete from sms_accpet;

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.只复制表结构到新表

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(假设两个表结构一样)

INSERT INTO 新表
SELECT * FROM 旧表

4.复制旧表的数据到新表(假设两个表结构不一样)

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