The MongoDB ODBC Driver is a powerful tool that allows you to connect with live MongoDB document databases, directly from any applications that support ODBC connectivity.

Access MongoDB like you would a database - read, write, and update through a standard ODBC Driver interface.

Using the CData ODBC Driver for MongoDB in PyCharm


Connect to MongoDB as an ODBC data source in PyCharm using the CData ODBC Driver for MongoDB.

The CData ODBC Drivers can be used in any environment that supports loading an ODBC Driver. In this tutorial we will explore using the CData ODBC Driver for MongoDB from within PyCharm. Included are steps for adding the CData ODBC Driver as a data source, as well as basic PyCharm code to query the data source and display results.

To begin, this tutorial will assume that you have already installed the CData ODBC Driver for MongoDB as well as PyCharm.

Add Pyodbc to the Project

Follow the steps below to add the pyodbc module to your project.

  1. Click File -> Settings to open the project settings window.
  2. Click Project Interpreter from the Project: YourProjectName menu.
  3. To add pyodbc, click the + button and enter pyodbc.
  4. Click Install Package to install pyodbc.

Connect to MongoDB

You can now connect with an ODBC connection string or a DSN. See the Getting Started section in the CData driver documentation for a guide to creating a DSN on your OS.

Set the Server, Database, User, and Password connection properties to connect to MongoDB. To access MongoDB collections as tables you can use automatic schema discovery or write your own schema definitions. Schemas are defined in .rsd files, which have a simple format. You can also execute free-form queries that are not tied to the schema.

Below is the syntax for a DSN:

[CData MongoDB Source] Driver = CData ODBC Driver for MongoDB Description = My Description Server = MyServer Port = 27017 Database = test User = test Password = Password

Execute SQL to MongoDB

Instantiate a Cursor and use the execute method of the Cursor class to execute any SQL statement.

import pyodbc cnxn = pyodbc.connect('DRIVER={CData ODBC Driver for MongoDB};Server = MyServer;Port = 27017;Database = test;User = test;Password = Password;') cursor = cnxn.cursor() cursor.execute("SELECT borough, cuisine FROM restaurants WHERE Name = 'Morris Park Bake Shop'") rows = cursor.fetchall() for row in rows: print(row.borough, row.cuisine)

After connecting to MongoDB in PyCharm using the CData ODBC Driver, you will be able to build Python apps with access to MongoDB data as if it were a standard database. If you have any questions, comments, or feedback regarding this tutorial, please contact us at support@cdata.com.
