mysql 获取所有用户所有权限存储过程

自己写的一个存储过程！一次性获取mysql所有用户的所有权限列表！
做权限列表统计的时候这个非常爽！
 

DELIMITER $$

USE `mysql`$$

DROP PROCEDURE IF EXISTS `proc_GetUserPriv`$$

CREATE DEFINER=`root`@`%` PROCEDURE `proc_GetUserPriv`(
    )
    COMMENT '获取账号权限信息列表'
BEGIN
 # 获取用户总数,用于循环判断
    SET @counts = (SELECT COUNT(*) FROM `user`);

    SET @i = 1;
    WHILE (@i <= @counts) DO
     -- SELECT CONCAT(`user`,'@',"'",`host`,"'") INTO @sql2 FROM USER LIMIT 2,
     -- set @SQL1 =  concat('SELECT',CONCAT(`USER`,"@'",`HOST`,"'"),'into @SQL2 FROM USER LIMIT ',@i,",1");      -- 这句会导致错误
     SET @SQL1 = CONCAT('select concat(','"',"'",'"',',user,','"',"'",'"',',','"@',"'",'",host,"',"'",'")','  into @SQL2 from user limit ',@i,",1");
     PREPARE smtm1 FROM @SQL1 ;
     EXECUTE smtm1;
     DEALLOCATE PREPARE smtm1;


     SET @sql3 = CONCAT("show grants for ",@SQL2);
     PREPARE smtm2 FROM @sql3;
     EXECUTE smtm2;
     DEALLOCATE PREPARE smtm2;
     SET @i = @i + 1;
    END WHILE;
    END$$

DELIMITER ;

嘿嘿，其实上面这个存储过程还可以用游标来实现！
之所以没用游标，是想上面这种方法在某些方面可以替代游标！
