Django and Python version compatibility
Each Django release supports specific Python versions. When choosing your versions, ensure compatibility between Django, Python, and mssql-django:
| Django version | Python versions |
|---|---|
| 6.0 | 3.12, 3.13, 3.14 |
| 5.2 | 3.10, 3.11, 3.12, 3.13 |
| 5.1 | 3.10, 3.11, 3.12, 3.13 |
| 5.0 | 3.10, 3.11, 3.12 |
| 4.2 | 3.8, 3.9, 3.10, 3.11, 3.12 |
| 4.1 | 3.8, 3.9, 3.10, 3.11 |
| 4.0 | 3.8, 3.9, 3.10 |
| 3.2 | 3.8, 3.9, 3.10 |
Important
Always use a supported Python version. Older Python versions don't receive security updates.
SQL Server version compatibility
The mssql-django backend works with all supported versions of SQL Server.
Azure SQL services
| Service | Support status |
|---|---|
| Azure SQL Database | Fully supported |
| Azure SQL Managed Instance | Fully supported |
Microsoft Fabric
| Endpoint | Support status |
|---|---|
| SQL database in Fabric | Fully supported |
ODBC driver compatibility
The mssql-django backend requires an external ODBC driver, unlike the mssql-python driver which uses Direct Database Connectivity (DDBC).
As of mssql-django 1.7, the backend defaults to ODBC Driver 18 for SQL Server and automatically falls back to ODBC Driver 17 if version 18 isn't installed. You can override this by specifying the driver option in your database configuration.
| ODBC driver | Support status |
|---|---|
| Microsoft ODBC Driver 18 for SQL Server | Fully supported (default) |
| Microsoft ODBC Driver 17 for SQL Server | Fully supported (fallback) |
| FreeTDS ODBC driver | Supported |
For installation instructions, see Download ODBC Driver for SQL Server.
Operating system compatibility
The mssql-django backend runs anywhere Python and the ODBC driver are supported. The ODBC driver installation steps vary by operating system. See Install mssql-django for platform-specific setup.
| Operating system | Architecture | Support status |
|---|---|---|
| Windows 11 | x64, ARM64 | Supported |
| Windows Server 2019, 2022, 2025 | x64 | Supported |
| Ubuntu 22.04, 24.04 | x64, ARM64 | Supported |
| Debian 11, 12 | x64, ARM64 | Supported |
| Red Hat Enterprise Linux 8, 9 | x64, ARM64 | Supported |
| macOS 14, 15 | Intel, Apple Silicon (ARM64) | Supported |
| Alpine Linux | x64 | Supported (requires glibc compatibility layer or FreeTDS) |
