Question

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

中插入搜索过的字词

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

以下查询是否有效？我需要在“宿舍”和“地址”栏中搜索

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

Answer 1

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

将带来更好的结果

Answer 2

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

Answer 3

这没有问题

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

使用LIKE 2列
