I can't compare them but I have what I believe to be a complete list

The text for MySQL is rather imprecise.

You can use MySQL all you want with closed source.

You can use the MySQL connectors all you want with closed source.

As long as you do not distribute.

If you distribute your stuff and it is "linked" with MySQL
code then then you need to buy a commercial license or
make your stuff GPL (or at least FLOSS when it is MySQL).

How to define "linked" can be a bit fuzzy.

But it is not something special for MySQL - this is
how GPL works.

It is rather unusual to use GPL for a library - often
LGPL (or an Apache/BSD style license) is chosen.

The true GPL believers will not consider that a problem.

But there are a reason that Apache/BSD sometimes is called
business friendly open source license.
