Generate SQL tables, load and extract data, based on JSON Table Schema descriptors.
Project description
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-sqlStorage
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.
