Here is some remarks. I know, I'm fast...

You have to specify the connection used by your MySQL class.

But you can do a better design by reimplementing the DB and the Connection 
class so that they have a property named MySQL that returns a dummy object 
that will have all the methods of the MySQL class.

Look:

-------------------------------------------------------
' _MySQL.class
' The "_" is needed, so that the user don't see it!
Export

Property Connection As Connection

... All methods of the old MySQL class
-------------------------------------------------------
' Connection.class
Export

Property Read MySQL As _MySQL

Private Sub MySQL_Read() AS _MySQL

  _MySQL.Connection = Me
  Return _MySQL

End
-------------------------------------------------------
' DB.class
Export

Property Read MySQL As _MySQL

Private Sub MySQL_Read() AS _MySQL

  _MySQL.Connection = DB.Current
  Return _MySQL

End
-------------------------------------------------------

Am I clear?

This way, the user will just have to do things like:

DB.MySQL.CreateDatabase()
MyConnection.MySQL.DropTables()

Otherwise, I think the interface of your table creation methods, and so on, 
could be better too, but I have no idea at the moment. You can search 
yourself! :-) Maybe copying the interface of DB and Connection, so that the 
user does not have too much to learn again?
