SQL Diagnostic Manager for SQL Server v14.1Major versionMay 21, 2026
Features
  • Introduces new AI-powered optimization workflows designed to help DBA diagnose and improve SQL Server performance faster and with greater confidence:
    • Use the AI Powered Query Optimization feature to optimize a single, problematic SQL query to reduce execution time based on your current schema and index structure.
    • Use the AI Powered Schema & Index Optimization feature to generate optimal index structures for a set of queries (up to five) to minimize cumulative execution time across all queries.
    • Use the AI Optimization History tab to view previous AI optimization sessions including queries analyzed, schema submitted, and AI recommendations. This tab provides a complete audit trail of all optimization activities performed in SQL DM.
  • These features are currently offered for SQL DM desktop version only.
  • SQL DM disables AI features by default. Contact your administrator to enable these features.
