SQL Server 2025 Adds Natural Language Search the Right Way

• SQL Server 2025 will include a natural language search capability (called vector search) that can be added to existing databases.
• The capability reduces the need to use external AI solutions for searching text data using natural language and can run on-premises to protect sensitive data.
• Vector search is built into the database engine, speeding deployment and allowing developers to choose their preferred large language model.
• It will likely increase resource requirements and licensing costs, and it is not suitable for all natural language search scenarios.

SQL Server 2025 (and other Azure SQL offerings) are adding AI-based vector search technology that supports using natural language queries to find data. Vector search is built into the SQL Server database engine and T-SQL language and can be added to existing databases. This capability will interest customers who want to add natural language search to existing database applications without relying on an external AI solution. However, customers should evaluate its impact on hardware and licensing requirements to determine suitability.
