This package contains the community driven pure-Python NuoDB client library that provides a standard PEP 249 SQL API. This is a community driven driver with limited support and testing from NuoDB.
If you don't have a NuoDB domain available you can create one using the Docker image on DockerHub. See Quick Start Guides / Docker.
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.
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()For further information on getting started with NuoDB, please refer to the Documentation.
