These are not working because MySQL is interpreting the database names as expressions.
Look closely at the db names:

This works fine.


Don't use database names starting with integers unless you use back ticks. 

This will work for you: 

mysql> create database `3208e1c6aa32`;

Though I would recommend not using such names. Some poor guy working on your application
six months down the line is going to wonder why his queries are failing, spend a day
trying to figure out and will post the same question again to this list :-)
