I don't think MySQL or even mysqli have any kind of exception throwing
yet, if ever.

If you didn't connect to the server, doing the select_db is rather
pointless, so I'd check the $connect FIRST, and deal with that
completely before trying to use a dead connection.
You don't put more money into the phone if the line is dead, do you?

There is nothing you'd be able to get from a thrown exception that you
can't get with mysql_errno() and vice versa, in theory.
In reality, it will probably be some time before every possile MySQL
error code number (and they are legion) would be encapsulated as an
Exception.
So for maxiumu customization, short-term, mysql_errno() is probably
the way to go.
I often, for example, simply want to IGNORE mysql_errno($connection)
== 1062 becaue it's just a duplicate key insert, and that means I've
already dealt with whatever I was trying to insert, and just don't
care.
