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; connections to other backends - Firebird, Sybase, MSSQL and MaxDB (also known as SAPDB) - are lesser debugged).

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
