如何使用 LIKE 通配符在列中搜索（不區分大小寫）？ - How can I search (case-insensitive) in a column using LIKE wildcard?

問題：

I looked around some and didn't find what I was after so here goes.我環顧四周，沒有找到我想要的東西，所以就這樣了。

SELECT * FROM trees WHERE trees.`title` LIKE  '%elm%'

This works fine, but not if the tree is named Elm or ELM etc...這工作正常，但如果樹被命名爲 Elm 或 ELM 等，則不行...

How do I make SQL case insensitive for this wild-card search?如何使此通配符搜索的 SQL 不區分大小寫？

I'm using MySQL 5 and Apache.我正在使用 MySQL 5 和 Apache。
