Python connectivity with CockroachDB

Full-featured and consistent SQL access to any supported data source through Python


Connecting to CockroachDB with Python

CData Python Connectors leverage the Database API (DB-API) interface to make it easy to work with CockroachDB from a wide range of standard Python data tools. Connecting to and working with your data in Python follows a basic pattern, regardless of data source:

  • Configure the connection properties to CockroachDB
  • Query CockroachDB to retrieve or update data
  • Connect your CockroachDB data with Python data tools.


Connecting to CockroachDB in Python

To connect to your data from Python, import the extension and create a connection:

Once you import the extension, you can work with all of your enterprise data using the python modules and toolkits that you already know and love, quickly building apps that help you drive business.

import cdata.cockroachdb as mod
conn = mod.connect("[email protected]; Password=password;")

#Create cursor and iterate over results
cur = conn.cursor()
cur.execute("SELECT * FROM NewSQLDB")
	
rs = cur.fetchall()
	
for row in rs:
print(row)
		
engine = create_engine("cockroachdb///Password=password&User=user")

df = pandas.read_sql("SELECT * FROM NewSQLDB", engine)

df.plot()
plt.show()

Visualize CockroachDB Data with pandas

The data-centric interfaces of the CockroachDB Python Connector make it easy to integrate with popular tools like pandas and SQLAlchemy to visualize data in real-time.

More than read-only: full update/CRUD support

CockroachDB Connector goes beyond read-only functionality to deliver full support for Create, Read Update, and Delete operations (CRUD). Your end-users can interact with the data presented by the CockroachDB Connector as easily as interacting with a database table.

AI-assisted development with CData CLI

Build CockroachDB integrations faster with AI that understands your schema

Schema-aware AI

CData CLI gives AI coding tools access to your CockroachDB schema. No more guessing table names or column types—AI sees the same metadata in your Python Connectors.

Your AI Knows SQL

How to find table names, column names, and how to generate SQL syntax are things that AI knows well from millions of training data. No need for customization, no hallucinations. Your AI acts like a domain specialist to CockroachDB.

More Accurate, More Token-Efficient

With CData CLI's queryable schema detection and highly efficient queries with filters, aggregation, joins with correct pushdown, your AI will achieve more accuracy with less token usage.
