Lesson Summary

  • Investigate performance fluctuations to understand how data changes impact query performance without SQL Plan Changes.
  • Analyze input parameters in parameterized queries to identify the root cause of performance variations without SQL Plan Changes.
  • Compare query performance with different parameter sets by creating and testing optimized plans.
  • Implement solutions such as SQL Plan Pinning or Plan Stability to ensure the consistent use of optimized plans.
  • Evaluate the need for query optimization techniques or application logic adjustments when parameter variations cause performance issues.
