An amusing MySQL weakness--not!

Earlier today I was working on a MySQL database (not by choice, I assure
you),
and I typed a statement like this:

Update tablexyz set field1 = '15' where field2 - 20;

The '-' was supposed to be an equal sign, but MySQL executed it anyway.
(Field2 is an integer.)

I was not amused.

PostgreSQL reports this as an error, of course.
