mysql 存储过程

示例
DELIMITER //
CREATE  PROCEDURE  proc (IN num INT)  
BEGIN  
SELECT  * FROM  v9_qd_account  limit num;  
END //
DELIMITER ;

执行:
SET @p_in=5;
CALL proc(@p_in);
或者
CALL proc(5);


循环
DECLARE num int default 5;
SET num = 1;
SET num = num + 1;

DELIMITER //  
CREATE PROCEDURE proc(IN sname VARCHAR(20),IN pwd VARCHAR(5),IN qd INT,IN start INT,IN end INT)  
	begin 
	DECLARE var INT;
	DECLARE myname VARCHAR(30);  
	SET var=start;  
	while var<end do  
		SET myname = CONCAT(sname,LPAD(var,3,'0'));
		insert into v9_qd_account (storename,password,qudao,regdate) value(myname,md5(pwd),qd,UNIX_TIMESTAMP());  
		SET var=var+1;  
	end while;  
	end //  
DELIMITER ; 

调用
CALL proc('test','123456',1,1,21);


查看
    SHOW PROCEDURE STATUS LIKE 'C%' G;  查看以字母C开头的存储过程
    SHOW CREATE PROCEDURE proc G;  查看状态和创建语句
    information_schema.Routines 中查看

删除
    DROP PROCEDURE IF EXISTS proc;
    DROP FUNCTION mytest;
