agate-sql 0.2.0 (alpha)

About

agate-sql adds SQL read/write support to agate.

Important links:

Install

To install:

pip install agatesql

For details on development or supported platforms see the agate documentation.

Warning

You’ll need to have the correct sqlalchemy drivers installed for whatever database you plan to access. For instance, in order to read/write tables in a Postgres database, you’ll also need to pip install psycopg2.

Usage

agate-sql uses a monkey patching pattern to add SQL support to all agate.Table instances.

import agate
import agatesql

agatesql.patch()

Calling patch() attaches all the methods of TableSQL() to agate.Table. For example, to import a table named doctors from a local postgresql database named hospitals you will use TableSQL.from_sql():

new_table = agate.Table.from_sql('postgresql:///hospitals', 'doctors')

To save this table back to the database:

new_table.to_sql('postgresql:///hospitals', 'doctors')

The first argument to either function can be any valid sqlalchemy connection string. The second argument must be a database name. (Arbitrary SQL queries are not supported.)

That’s all there is to it.

API

agatesql.patch()

Patch the features of this library onto agate’s core Table and TableSet.
