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,
‘%‘));
