SQLObject 3.11.1a0

SQLObject is a free and open-source (LGPL) Python 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/MariaDB (with a number of DB API drivers: MySQLdb, mysqlclient, mysql-connector, PyMySQL, mariadb), PostgreSQL (psycopg2, PyGreSQL, partially pg8000 and py-postgresql), SQLite (builtin sqlite, pysqlite); connections to other backends - Firebird, Sybase, MSSQL and MaxDB (also known as SAPDB) - are less debugged).

Python 2.7 or 3.4+ is required.

Example

Install:

$ pip install sqlobject

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
