// mysql中使用concat连接字符串 select t1.id, t1.title, t2.keyword from t1 inner join t2 on t1.title like concat('%', t2.keyword, '%'); 其它思路:exists(是否存在)、regexp(正则)、instr(字符串包含) select distinct t1.title from t1 , t2 where instr(t1.title,t2.keyword); select distinct t1.title from t1 inner join t2 on t1.title regexp t2.keyword; select * from t1 where exists (select keyword from t2 where t1.title regexp keyword); select * from t1 where exists (select keyword from t2 where t1.title like concat('%',keyword,'%'));
