sql-helper 0.0.17

Helper funcs and tools for working with SQL in mysql, postgresql, and more

About

This is meant to be a simple way to explore a postgresql/mysql/sqlite database and get data out (super light wrapper to SQLAlchemy).

Connect with DB url in the following formats:

• postgresql://someuser:somepassword@somehost[:someport]/somedatabase

• mysql://someuser:somepassword@somehost[:someport]/somedatabase

• sqlite:///somedb.db

Note: This package uses pymysql driver for connecting to mysql. Urls that start with mysql:// will automatically be changed to use mysql+pymysql://.

Install

Ensure the pg_config executable is on the system

$ sudo apt-get install -y libpq-dev

or

$ brew install postgresql

Then install sql-helper

$ pip3 install sql-helper

Usage

In [1]: from sql_helper import SQL

In [2]: sql = SQL('postgresql://someuser:somepassword@somehost/somedatabase')

Extra

Redshift
