mssql-python is a Python driver for Microsoft SQL Server and the Azure SQL family of databases. It leverages Direct Database Connectivity (DDBC) that enables direct connections to SQL Server without requiring an external driver manager. Designed to comply with the DB API 2.0 specification, this driver also introduces Pythonic enhancements for improved usability and functionality. It supports a full range of database operations, including connection management, query execution, and transaction handling.

Note: This project is currently in an alpha phase, meaning it is still under active development. We are looking to validate core functionalities and gather initial feedback before a broader public launch. Please use with caution and avoid production environments.

mssql-python can be installed with pip

pip install mssql-python

Windows

Note: Support for macOS and Linux is coming soon

The Microsoft mssql-python module is designed to be fully compliant with the DB API 2.0 specification. This ensures that the driver adheres to a standardized interface for database access in Python, providing consistency and reliability across different database systems. Key aspects of DBAPI v2.0 compliance include:

• Connection Objects: Establishing and managing connections to the database.
• Cursor Objects: Executing SQL commands and retrieving results.
• Transaction Management: Supporting commit and rollback operations to ensure data integrity.
• Error Handling: Providing a consistent set of exceptions for handling database errors.
• Parameter Substitution: Allowing the use of placeholders in SQL queries to prevent SQL injection attacks.

By adhering to the DB API 2.0 specification, the mssql-python module ensures compatibility with a wide range of Python applications and frameworks, making it a versatile choice for developers working with Microsoft SQL Server, Azure SQL Database, and Azure SQL Managed Instance.

The Microsoft mssql-python driver enables Python applications to connect to Microsoft SQL Server, Azure SQL Database, or Azure SQL Managed Instance using Microsoft Entra ID identities. It supports various authentication methods, including username and password, Microsoft Entra managed identity, and Integrated Windows Authentication in a federated, domain-joined environment. Additionally, the driver supports Microsoft Entra interactive authentication and Microsoft Entra managed identity authentication for both system-assigned and user-assigned managed identities.

The driver offers a suite of Pythonic enhancements that streamline database interactions, making it easier for developers to execute queries, manage connections, and handle data more efficiently.

Connect to SQL Server and execute a simple query:

import mssql_python

# Establish a connection
# Specify connection string
connection = ("SERVER=<your_server_name>;DATABASE=<your_database_name>;UID=<your_user_name>;PWD=<your_password>;Encrypt=yes;")

# Execute a query
cursor = connection.cursor()
cursor.execute("SELECT * from customer")
rows = cursor.fetchall()

for row in rows:
    print(row)

# Close the connection
connection.close()
