Requirements

• Python >= 2.7

  • Recommended Python version >= 3.8

  • Tested with CPython 2.7 and 3.6

• NuoDB >= 6.0.2

Installation

The current stable release is available on PyPI and can be installed with pip:

$ pip install pynuodb

Alternatively (e.g. if pip is not available), a tarball can be downloaded from GitHub and installed with Setuptools:

$ curl -L https://github.com/nuodb/nuodb-python/archive/master.tar.gz | tar xz
$ cd nuodb-python*
$ python setup.py install
# The folder nuodb-python* can be safely removed now.

Example

Here is an example using the PEP 249 API that creates some tables, inserts some data, runs a query, and cleans up after itself:

import pynuodb

options = {"schema": "test"}
connect_kw_args = {'database': "test", 'host': "localhost", 'user': "dba", 'password': "dba", 'options': options}

connection = pynuodb.connect(**connect_kw_args)
cursor = connection.cursor()
try:
    stmt_drop = "DROP TABLE IF EXISTS names"
    cursor.execute(stmt_drop)

    stmt_create = """
    CREATE TABLE names (
        id BIGINT NOT NULL GENERATED ALWAYS AS IDENTITY PRIMARY KEY,
        name VARCHAR(30) DEFAULT '' NOT NULL,
        age INTEGER DEFAULT 0
    )"""
    cursor.execute(stmt_create)

    names = (('Greg', 17,), ('Marsha', 16,), ('Jan', 14,))
    stmt_insert = "INSERT INTO names (name, age) VALUES (?, ?)"
    cursor.executemany(stmt_insert, names)

    connection.commit()

    age_limit = 15
    stmt_select = "SELECT id, name FROM names where age > ? ORDER BY id"
    cursor.execute(stmt_select, (age_limit,))
    print("Results:")
    for row in cursor.fetchall():
        print("%d | %s" % (row[0], row[1]))

finally:
    cursor.execute(stmt_drop)
    cursor.close()
    connection.close()
