We can add this to the Docs, but since Directus is a Database wrapper, most admins setting it up should be familiar with settings like this.
Now that you said this I remember I wanted to check on mysql docs, but totally forgot 馃檲
But thx for clarification.
It's long time ago since I worked with SQL so I'm not too deep into it anymore. So maybe it would be a good idea to at least reference the SQL docs.
Yeah, absolutely! I've added it here:
