Mysql 将LIKE用于2列

我需要在

hostel

表中搜索

结构：

CREATE TABLE hostel( 
p_id VARCHAR(5) NOT NULL,
hostel VARCHAR(50) NOT NULL,
address VARCHAR(50) NOT NULL
PRIMARY KEY(p_id));

我已在

$word

select * from hostel where hostel like '%$word%'

下面的查询是否有效？我需要在“招待所”和“地址”栏中搜索

这是没有问题的

会带来更好的结果

为什么不直接测试一下呢？这取决于你想要什么。您的查询将只生成hotels，其中hotel和address包含文本$word。我认为您需要将AND更改为OR，这样当hotel或address包含$word时，它将返回行。

Better change those searchable fields(hostel,address) to full text which will fasten the search

SELECT MATCH('Content') AGAINST ('keyword1
keyword2') as Relevance FROM table 

select match($word) against (hostel,address)  as Relevance FROM table 

select * from hostel where hostel like '%$word%' AND address like '%$word%'

select * from hostel where hostel like '%$word%' OR address like '%$word%'

Better change those searchable fields(hostel,address) to full text which will fasten the search

SELECT MATCH('Content') AGAINST ('keyword1
keyword2') as Relevance FROM table 

select match($word) against (hostel,address)  as Relevance FROM table
