Vertica dialect for sqlalchemy

Project description

Vertica dialect for sqlalchemy

This module implements a Vertica dialect for SQLAlchemy. You can use it:

>>> import sqlalchemy as sa
>>> sa.create_engine(sa.engine.url.URL(
    drivername='vertica+pyodbc',
    username='myusername',
    password='mypassword',
    host='hostname',
    database='dbname',
))

This work is mainly a package of code [posted](https://groups.google.com/d/msg/sqlalchemy/ttJzN-t9R74/9W1d9KfHK_0J) to the SQLAlchemy mailing list by ‘Bo’ (Google groups won’t let me see the original author).

I have tested this for table introspection, selects and joins. However, I do not have access to a Vertica database to test against. If you do, let me know.

The primary, foreign and index constraints return nothing. This is because I’m told these are ‘enforced on select’. Maybe a Vertica expert can tell me the correct way to handle this.
