adbc-driver-netezza 0.0.4

A libpq-based ADBC driver for working with Netezza.

Updated Readme

ADBC Netezza Driver for Python

This package contains bindings for the Netezza driver, using the driver manager to provide a DBAPI 2.0/PEP 249-compatible interface on top.

Example

import adbc_driver_netezza.dbapi

uri = "netezza://username:password@localhost:5480/database_name"
with adbc_driver_netezza.dbapi.connect(uri) as conn:
    with conn.cursor() as cur:
        cur.execute("SELECT 1")
        print(cur.fetch_arrow_table())

Building

Dependencies: a build of the Netezza driver, and the adbc-driver-manager Python package. Optionally, install PyArrow to use the DBAPI 2.0-compatible interface.

Set the environment variable ADBC_NETEZZA_LIBRARY to the path to libadbc_driver_netezza.so before running pip install.

# If not already installed
pip install -e ../adbc_driver_manager

export ADBC_NETEZZA_LIBRARY=/path/to/libadbc_driver_netezza.so
pip install --no-deps -e .

For users building from the arrow-adbc source repository, you can alternately use CMake to manage library dependencies and set environment variables for you. Assuming you specify -DADBC_DRIVER_NETEZZA=ON you can also add -DADBC_BUILD_PYTHON=ON to define a python target.

For example, assuming you run cmake from the project root:

cmake -S c -B build --preset debug -DADBC_BUILD_PYTHON=ON
cmake --build build --target python

will properly build and install the Python library for you.

See CONTRIBUTING.md for details on the general build process.

Testing

A running instance of Netezza is required.

To run the tests, set the environment variable specifying the Netezza URI before running tests:

$ export ADBC_NETEZZA_TEST_URI=netezza://localhost:5432/netezza?user=username&password=password
$ pytest -vvx

See CONTRIBUTING.md for details on the general test process.
