A SQL/database library

Project description

master Travis CI Status PyPi package version Documentation Status

quma is a small SQL database library for Python and PyPy version 3.5 and higher. It maps object methods to SQL script files and supports SQLite, PostgreSQL, MySQL and MariaDB.

Unlike ORMs, it allows to write SQL as it was intended and to use all features the DBMS provides. As it uses plain SQL files you can fully utilize your database editor or IDE to author your queries.

It also provides a simple connection pool.

Installation

pip install quma

Quick Start

The full documentation is available at https://quma.readthedocs.io

Given a directory with some SQL scripts e. g.:

/path/to/sql/scripts
├── users
│    ├── all.sql
│    └── remove.sql
└── get_admin.sql

You can access these scripts after connecting to the database:

from quma import Database

db = Database('sqlite:///:memory:', '/path/to/sql/scripts')

db.execute('CREATE TABLE users ...')

with db.cursor as cur:
    all_users = cur.users.all()

    for user in all_users:
        print(user['name'])

    cur.users.remove(id=user['id']).run()
    cur.commit()

    admin = cur.get_admin()
