  • ... that apparently MySQL is a bit like Perl, the first thing you need to do is "use strict"...

    Have you enabled strict mode?

    Note: I have no freaking idea how to turn it on myself, but I think it's being positioned as a "gotcha" ala use strict.

      mysql> grant all on no_such_database.* to 'no_such_user'@'%' identified by 'some_password';

      But it's quite possible I'm misunderstanding this (and it's annoying as hell that "strict mode" appears to be "per connection" (though you can apparently set it up for the server, too).
