Defy all challenges. Microsoft(R) Visual Studio 2008.
Currently SQLObject can only create an empty DB on PostgreSQL, and even
this has its limitations.
Usually one has to have administrative rights to create a new DB, and
then delegates rights to connect to the new DB to another user
(login/password), so it'd be hard to implement in
So the code should be (providing that SQLObject's connection knows the
user as self.user and self.password):
con = kinterbasdb.create_database(create database '%s' user '%s' password

You need to run your own SQL queries. Something like this:

You can handle some more complex SQL SELECT within the view.
