SQL WHERE 字符串 LIKE 字段 [英] SQL WHERE string LIKE field

问题描述

我有一个表格跟踪链接结构如下:

id域名交通计数启用created_at

假设我有一个 domain_name 为some-domain.com"的记录，然后假设我想找到具有该域的记录，除了我必须经过的是该域的子域.

我本质上想这样做:

SELECT * FROM links 'subdomain.some-domain.com' LIKE %domain_name%"

我该怎么做?

解决方案

更新(感谢 Chad Johnson):

SELECT * FROM links WHERE 'subdomain.some-domain.com' LIKE CONCAT('%', domain_name, '%')

I have a table tracking links structured as follows:

id
domain_name
traffic_count
enabled
created_at

Let's say I have a record with domain_name of "some-domain.com", and then let's say I want to find the record having that domain, except all I have to go by is a subdomain of that domain.

I essentially want to do this:

SELECT * FROM links 'subdomain.some-domain.com' LIKE %domain_name%"

How would I do this?

解决方案

Updated (thanks to Chad Johnson):

SELECT * FROM links WHERE 'subdomain.some-domain.com' LIKE CONCAT('%', domain_name, '%')
