Debugging SQL Performance in Dynamics 365 F&O
SQL performance directly impacts transaction speed and batch job efficiency. Understanding how to analyze queries and optimize indexes helps administrators and developers maintain a responsive environment. 1. Identify Slow Queries Use Database Trace and Performance Profiler in Visual Studio. Capture query execution plans. Focus on queries with high I/O or long duration. 2.
