sqlalchemy-vertica-python

Vertica dialect for sqlalchemy. Forked from the Vertica ODBC dialect, written by James Casbon.

This module implements a Vertica dialect for SQLAlchemy using the pure-Python DB-API driver vertica-python, as adapted by Luke Emery-Fertitta.

It is currently maintained by BlueLabs - PRs are welcome!

Engine creation:

import sqlalchemy as sa
sa.create_engine('vertica+vertica_python://user:pwd@host:port/database')

Installation

From PyPI:

pip install sqlalchemy-vertica-python

From git:

git clone https://github.com/bluelabsio/vertica-sqlalchemy-python
cd vertica-sqlalchemy-python
python setup.py install

Usage

ID/Primary Key Declaration

Do not use this. The INSERT will fail as it will try to insert the ID

id = Column(Integer, primary_key=True)

Do the following instead

id = Column(Integer, Sequence('user_id_seq'), primary_key=True)
