CData ODBC Driver for Azure Cosmos DB

Overview

The CData ODBC Driver for Azure Cosmos DB enables real-time access to Azure Cosmos DB data, directly from any applications that support ODBC connectivity, the most widely supported interface for connecting applications with data.

The driver wraps the complexity of accessing Azure Cosmos DB data in a standard ODBC driver compliant with ODBC 3.8. Applications can then access Azure Cosmos DB as a traditional database. The driver hides the complexity of accessing data and provides additional powerful security features, smart caching, batching, socket management, and more.

Key Features

• Bidirectional access.
• Access, analyze, and report on data with your SQL-based tool of choice.
• Supports 32-bit and 64-bit applications.
• Supports the Unicode ODBC APIs and ODBC 3.8.
• Drivers for Windows, Linux, and macOS/OS X.

Getting Started

See Getting Started to create an ODBC data source name (DSN) and connect to Azure Cosmos DB from your platform.

Using the ODBC Driver/Using from Tools

See Using ODBC to connect to Azure Cosmos DB from the following programming languages and for information on the supported interfaces:

• From C/C++
• From Go
• From Node.js
• From PHP
• From Python
• From R

See Using from Tools for information on using the ODBC driver in some of the popular applications and programming languages that connect via ODBC.

See the Azure Cosmos DB integration guides for information on connecting from other applications.

Linked Server

You can use SQL Linked Server to connect to the CData SQL Gateway. SQL Server treats the CData SQL Gateway as a linked SQL Server instance, so you can write full SQL queries to query your Azure Cosmos DB data without losing performance as would happen connecting to an ODBC data source directly. The connection can be made locally or to the Gateway located on a separate machine.

See Create a Linked Server for more information.

SQL Gateway

See Connect from MySQL Workbench to configure MySQL or SQL Server entry points for Azure Cosmos DB on your server, using the included CData SQL Gateway application. The SQL Gateway listens for incoming MySQL and SQL Server connections and brokers the SQL request to the ODBC data source. This enables any MySQL or SQL Server client to connect, from PHP applications, SQL Server linked servers, and so on.

Advanced Features

Advanced Features details additional features supported by the driver, such as defining user defined views, ssl configuration, remoting, caching, firewall/proxy settings, and advanced logging.

SQL Compliance

See SQL Compliance for a syntax reference and code examples outlining the supported SQL.
