SQL for the enhanced.

Project description

Latest Version Build Coverage License

ezrecords is a very simple, but powerful, library for making raw SQL queries to most relational databases.

ezrecords = Kenneth Reitz’s records + Justin Vincent’s ezsql + WordPress’ wpdb - SQLAlchemy.

Just write SQL. No bells, no whistles. This common task can be surprisingly difficult with the standard tools available. This library strives to make this workflow as simple as possible, while providing an elegant interface to work with your query results.

Database support includes SQLite, Postgres, and MySQL (drivers not included).


  • records is awesome
  • ezsql and wpdb have very nice API, so it makes for an easy transition from PHP to Python
  • Our love for crafting well written and performant SQL queries is not questionable, but I think a few helpers for some basic DML and recurring queries would help
  • “The ORM takes two brilliant ideas and incapacitates them both.”, said a very wise man. So, as long as possible I want to keep away from sqlalchemy or the like.

# Get number of affected rows from previus query

# Switch to another database

# Check query timing
# execute long running query

# Transactions
# ---
db.commit() # or db.rollback()

# Data export
rows = db.query('SELECT * FROM table')
rows.export('csv') # yaml, json, xls, xlsx

# Goodies
db.db_version() # get server version
db.exists('table') # check if table exists
db.get_table_names() # get list of tables in database

Thank you

Thanks for checking this library out! I hope you find it useful.

Of course, there’s always room for improvement. Feel free to open an issue so we can make ezrecords better, faster, and stronger.

Download and Install

Until the module is made available on pypi, you can install this module directly from github with:

pip install -e git+

ezrecords runs with Python 2.7 and 3.5.
