SQL Server 2025
Microsoft's next-generation relational database management system, introducing AI-enhanced capabilities including vector search and in-engine REST calls. It targets enterprise-level scenarios that combine data management with AI integration.
Timeline (last 90 days)
Foundry Local provides local model endpoints as a Kubernetes service, and SQL Server 2025 can directly call its embedding and chat completion capabilities, keeping data from leaving the premises.
SQL Server 2025's T-SQL directly supports regular expression matching and replacement.
SQL Server 2025's Change Event Streaming replaces the traditional CDC polling model and can push changes directly to Azure Event Hub.
SQL Server 2025 can run on Azure Local, supports connected or disconnected modes, and is managed through the Arc control plane.
SQL Server 2025 has been officially released.
SQL Server 2025 adds a native vector data type column and approximate nearest neighbor (ANN) indexes, supporting the combination of vector search with WHERE clause filtering in SQL statements.
SQL Server 2025 implements the RAG pattern within the engine through system stored procedures and model definitions, and records AI interactions in Ledger tables to provide a tamper-proof audit trail.
SQL Server 2025's RAG and AI capabilities are exposed to the application layer through MCP Server, enabling SQL Server to serve as the data and reasoning hub for AI Agent applications.
SQL Server 2025 introduces about 40 new features at the core engine level, covering security, performance and availability.
SQL Server 2025's Optimized Locking avoids lock escalation through a versioned transaction locking mechanism, and depends on Accelerated Database Recovery (ADR) and Read Committed Snapshot Isolation (RCSI).
