Microsoft SQL Server 2022 vs 2025: Features, Licensing, and Pricing Comparison
Microsoft’s SQL Server 2025 represents a transformative leap in database technology, positioning itself as the premier AI-ready enterprise database platform. With groundbreaking vector data types, enhanced cloud integration, and substantial performance improvements, SQL Server 2025 builds upon the solid foundation established by SQL Server 2022 while introducing capabilities that enable modern AI-powered applications [1].
This comprehensive comparison examines the key differences between SQL Server 2022 and 2025, covering new features, removed capabilities, licensing models, and pricing structures to help organizations make informed infrastructure decisions.
New Features in SQL Server 2025
SQL Server 2025 introduces revolutionary AI capabilities that distinguish it from its predecessor. The most significant addition is native vector data type support, enabling organizations to store and manipulate vector embeddings directly within the database engine [1]. This capability includes specialized vector functions for similarity searches and machine learning operations, along with optimized vector indexing for high-performance AI workloads.
The platform integrates Microsoft Copilot directly into SQL Server Management Studio, allowing administrators to ask natural language questions and receive data-driven answers [1]. Enhanced Azure Arc integration provides seamless hybrid cloud management, while improved automatic plan correction with Trace Flag 12618 enabled by default optimizes query performance automatically [1].
Security enhancements include expanded TDS 8.0 support across SQL VSS Writer, SQL CEIP service, and PolyBase components. The database engine introduces percent-based limits for tempdb space resource governance and immutable storage support for Azure Blob Storage backups [1].
Removed and Deprecated Features
Unlike Windows Server 2025, SQL Server 2025 maintains backward compatibility with minimal feature removal. The primary changes involve optimization and modernization rather than elimination of legacy components. Enhanced vector capabilities replace several previous limitations, while automatic plan correction improvements supersede manual tuning requirements in many scenarios [1].
The focus on AI integration and cloud connectivity represents an evolution rather than replacement of existing functionality, ensuring smooth migration paths for organizations upgrading from SQL Server 2022.
