Generate and load SQL tables based on JSON Table Schema descriptors.

Version v0.3 contains breaking changes:
  • renamed Storage.tables to Storage.buckets
  • changed Storage.read to read into memory
  • added Storage.iter to yield row by row

Getting Started

Installation

pip install jsontableschema-sql

Storage

Package implements Tabular Storage interface.

SQLAlchemy is used as sql wrapper. We can get storage this way:

from sqlalchemy import create_engine
from jsontableschema_sql import Storage

engine = create_engine('sqlite:///:memory:', prefix='prefix')
storage = Storage(engine)

Then we could interact with storage:

storage.buckets
storage.create('bucket', descriptor)
storage.delete('bucket')
storage.describe('bucket') # return descriptor
storage.iter('bucket') # yield rows
storage.read('bucket') # return rows
storage.write('bucket', rows)

Mappings

schema.json -> SQL table schema
data.csv -> SQL talbe data

Drivers

SQLAlchemy is used - docs.
