像 MySQL 中区分大小写

问题描述

我有一个 MySQL 查询:

I have a MySQL query:

SELECT concat_ws(title,description) as concatenated HAVING concatenated LIKE '%SearchTerm%';

我的表使用 MyISAM 编码为 utf8_general_ci.

And my table is encoded utf8_general_ci with MyISAM.

搜索似乎区分大小写.

我不知道如何修复它.出了什么问题和/或我该如何解决?

I can't figure out how to fix it. What's going wrong and/or how do I fix it?

推荐答案

试试这个:

SELECT LOWER(CONCAT_WS(title,description)) AS concatenated 
WHERE concatenated LIKE '%searchterm%'

或(让你看出区别)

SELECT LOWER(CONCAT_WS(title,description)) AS concatenated 
WHERE concatenated LIKE LOWER('%SearchTerm%')
