mysql-定時調用存儲過程

mysql定時調用存儲過程，對表數據集表結構進行備份

存儲過程實例：

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.復制表結構及數據到新表

CREATE TABLE 新表
SELECT * FROM 舊表

2.只復制表結構到新表

CREATE TABLE 新表
SELECT * FROM 舊表 WHERE 1=2
即:讓WHERE條件不成立.
方法二:(低版本的mysql不支持，mysql4.0.25 不支持，mysql5已經支持了)
CREATE TABLE 新表
LIKE 舊表

3.復制舊表的數據到新表(假設兩個表結構一樣)

INSERT INTO 新表
SELECT * FROM 舊表

4.復制舊表的數據到新表(假設兩個表結構不一樣)

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

每天凌晨三點執行  
create event event_call_defer     
on schedule every 1 day starts date_add(date(curdate() + 1),interval 3 hour)  
on completion preserve enable  
do  
begin  
    call test.warn();  
end  
  
每個月的一號凌晨1 點執行  
CREATE EVENT EVENT2    
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  
 BEGIN  
     CALL STAT();  
 END  
   
每個季度一號的凌晨2點執行

HOUR)  
ON COMPLETION PRESERVE ENABLE  
DO  
 BEGIN  
     CALL SEASON_STAT();  
 END  
   
  
每年1月1號凌晨四點執行
