When I try and make my database read only (not for any actual purpose, just for the sake of seeing that I can), MySQL tells me that I have a syntax error.

This is what I tried:

ALTER DATABASE database_name READ ONLY = 1;

Apparently the problem itself is that “unrecognized alter operation”. My database exists and I’m currently using it, so it’s not something like that. Also, I have the most recent MySQL, if that helps at all.
