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.
Requirements
------------
* Python -- one of the following:
- CPython_ >= 2.7
* NuoDB -- one of the following:
- NuoDB_ >= 2.0.4
If you don't have a NuoDB domain available you can create one using the Docker
image on DockerHub. See `Quick Start Guides / Docker <https://doc.nuodb.com/nuodb/latest/quick-start-guide/docker/>`_.
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:
.. code:: python
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()
