Hello!

I'm pleased to announce version 3.13.1b1, the first beta of the upcoming
bugfix release 3.13.1 of SQLObject.

Please test it and report problems. Do not use in production without
testing first.

The contributors for this release are:

* Igor Yudytskiy. Thanks for PR #194:
  fix: connect to old mssql versions via set tds_version uri parameter.

* Dave Mulligan fixed #195: Minor ``NameError`` in ``pgconnection.py``
  when using ``psycopg`` version 1 with a non-default port. Thanks!

What is SQLObject
=================

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 (``psycopg``, ``psycopg2``, ``PyGreSQL``,
partially ``pg8000``), SQLite (builtin ``sqlite3``);
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
