这样的条件，如何用sql实现查询
数据库结构：


CREATE TABLE IF NOT EXISTS `phpa_ssq` (
  `num1` varchar(2) COLLATE utf8_bin NOT NULL DEFAULT '',
  `num2` varchar(2) COLLATE utf8_bin NOT NULL DEFAULT '',
  `num3` varchar(2) COLLATE utf8_bin NOT NULL DEFAULT '',
  `num4` varchar(2) COLLATE utf8_bin NOT NULL DEFAULT '',
  `num5` varchar(2) COLLATE utf8_bin NOT NULL DEFAULT '',
  `num6` varchar(2) COLLATE utf8_bin NOT NULL DEFAULT '',
  PRIMARY KEY (`number`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin;

对应记录：
num1num2num3num4num5num6
100120150170200500
56100120170220280

我想统计：100,500这两个数字在所有记录中出现的记录。如何写sql呢？

如第一条记录就符合，num1为100，num6为500，而第二条记录则不符合。

SQL code

select * from phpa_ssq where find_in_set('100',concat_ws(',',num1,num2,num3,num4,num5,num6) ) and find_in_set('500',concat_ws(',',num1,num2,num3,num4,num5,num6) );
[解决办法]
SQL code
select * from phpa_ssq awhereinstr(concat(num1,',',num2,',',num3,',',num4,',',num5,',',num6),'100')>0andinstr(concat(num1,',',num2,',',num3,',',num4,',',num5,',',num6),'500')>0;
[解决办法]
SQL code
mysql> select * from phpa_ssq where find_in_set(100,concat_ws(',',num1,num2,num3,num4,num5,num6) ) and 
   ->  find_in_set(500,concat_ws(',',num1,num2,num3,num4,num5,num6) ); 
 +------+------+------+------+------+------+
