sqlalchemy-intersystems-iris 1.0.1

An InterSystems IRIS dialect for SQLAlchemy

sqlalchemy-intersystems-iris

This package provides an InterSystems IRIS dialect for SQLAlchemy, built for use with the InterSystems Python DB-API driver.

Installation

Install sqlalchemy-intersystems-iris with pip:

pip install sqlalchemy-intersystems-iris

The InterSystems Python DB-API driver is a dependency and will be automatically installed or upgraded to a compatible version.

Usage

You can connect your Python application to an InterSystems IRIS database by passing a connection URL to create_engine(). The URL can be a string or a SQLAlchemy URL object.

A connection string for InterSystems IRIS has the format iris://{username}:{password}@{host}:{port}/{namespace}. For example:

from sqlalchemy import create_engine

url = "iris://SQLUser:password@localhost:1972/USER"

engine = create_engine(url)

You can construct a SQLAlchemy URL with URL.create(). Note that the database field corresponds to an InterSystems IRIS namespace:

from sqlalchemy import create_engine
from sqlalchemy import URL

url = URL.create(
    drivername='iris',
    username='SQLUser',
    password='password',
    host='localhost',
    port=1972,
    database='USER',
)

engine = create_engine(url)

As these examples demonstrate, you do not need to import the dialect package directly — the SQLAlchemy engine will automatically load the correct dialect based on the connection URL.

For details on the features supported by InterSystems IRIS SQL, see the InterSystems IRIS SQL documentation.
