About:
FreeTDS is a set of open-source libraries that enables applications to communicate with Microsoft SQL Server and Sybase databases using the Tabular Data Stream protocol. It provides drivers for various database APIs including ODBC and DB-Library, allowing for seamless database connectivity on Unix/Linux systems and other platforms. This makes it an essential tool for integrating legacy and modern systems with Microsoft SQL Server environments.
Key Features:
  • Supports TDS protocol versions 4.2, 5.0, and 7.0+ for broad compatibility
  • Provides ODBC, DB-Library, and CT-Library APIs for application development
  • Cross-platform support including Linux, macOS, and BSD systems
  • Compatible with multiple database versions from SQL Server 6.5 to Azure SQL
Use Cases:
  • Connecting Linux-based applications to Microsoft SQL Server databases
  • Enabling ODBC-based reporting and analytics tools to access Sybase data
  • Migrating legacy applications that rely on DB-Library to modern database systems
Alternatives:
  • Microsoft ODBC Driver for SQL Server – Official Microsoft driver, typically offers better performance and newer feature support but is Linux-only and has a more restrictive license
  • pyodbc – Python-specific ODBC wrapper that often uses FreeTDS as its underlying driver on Unix systems
