MySQL生成随机密码

 

我简化了步骤, 比之前的更加简洁,常规生成随机密码。

[sql] 

DELIMITER $$  

  

  

USE `t_girl`$$  

  

  

DROP FUNCTION IF EXISTS `func_range_string_mod`$$  

  

  

CREATE DEFINER=`root`@`localhost` FUNCTION `func_range_string_mod`(  

    f_num INT UNSIGNED -- Total strings.  

    ) RETURNS VARCHAR(200) CHARSET latin1  

BEGIN  

      

      DECLARE i INT UNSIGNED DEFAULT 0;   

      DECLARE v_result VARCHAR(200) DEFAULT '';   

      DECLARE v_dict VARCHAR(200) DEFAULT '';  

      SET v_dict = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';  

      SET v_dict = LPAD(v_dict,200,v_dict);  

      WHILE i

      DO   

    SET v_result = CONCAT(v_result,SUBSTR(v_dict,CEIL(RAND()*200),1));  

        SET i = i + 1;   

      END WHILE;    

      RETURN v_result;   

    END$$  

  

  

DELIMITER ;  

 

调用方法:

 

select func_range_string_mod(20); 代表需要生成20个字符长度的密码。
