推荐答案
在 Unix 上，表名区分大小写.在 Windows 上，它们不是.有趣，不是吗?有点像他们各自的文件系统.你认为这是巧合吗?
On Unix, table names are case sensitive. On Windows, they are not. Fun, isn't it? Kinda like their respective file systems. Do you think it's a coincidence?
换句话说，如果您计划在 Linux 机器上部署，最好也针对基于 Linux 的 MySQL 测试您的 SQL，或者在生产时为神秘的找不到表"错误做好准备.现在虚拟机很便宜.
In other words, if you are planning on deploying on a Linux machine, better test your SQL against a Linux-based MySQL too, or be prepared for mysterious "table not found" errors at prod time. VMs are cheap these days.
字段(列)名称不区分大小写.
Field (column) names are case-insensitive regardless.
我们讨论的是 MySQL 服务器 机器上的操作系统，而不是客户端.
we're talking about the operating system on the MySQL server machine, not client.
