It'd be even more logical to write:

UPDATE visitors INCREMENT visits WHERE host CONTAINS %s;

I should just use that syntax, and if it doesn't work, I'm going to
post onto a mailing list until it magically starts working. It's NOT
that I haven't read the docs - I'm just going to wilfully ignore them.

Okay, I'm done now.
