What is SQLObject
=================
SQLObject is an object-relational mapper. Your database tables are described
as classes, and rows are instances of those classes. SQLObject is meant to be
easy to use and quick to get started with.
SQLObject supports a number of backends: MySQL, PostgreSQL, SQLite,
Firebird, Sybase, MSSQL and MaxDB (also known as SAPDB).
Python 2.7 or 3.4+ is required.

Example
=======
Create a simple class that wraps a table::
>>> from sqlobject import *
>>>
>>> sqlhub.processConnection = connectionForURI('sqlite:/:memory:')
>>>
>>> class Person(SQLObject):
... fname = StringCol()
... mi = StringCol(length=1, default=None)
... lname = StringCol()
...
>>> Person.createTable()
Use the object::
>>> p = Person(fname="John", lname="Doe")
>>> p
<Person 1 fname='John' mi=None lname='Doe'>
>>> p.fname
'John'
>>> p.mi = 'Q'
>>> p2 = Person.get(1)
>>> p2
<Person 1 fname='John' mi='Q' lname='Doe'>
>>> p is p2
True
Queries::
>>> p3 = Person.selectBy(lname="Doe")[0]
>>> p3
<Person 1 fname='John' mi='Q' lname='Doe'>
>>> pc = Person.select(Person.q.lname=="Doe").count()
>>> pc
1
