I have setup a trace capturing session and saved the file. Now, how do I find out which query(s) cost the most or least optimized? Thanks!
There are three SQL server query optimization steps:
1.Detect critical parts that need to be improved.
2.Analyze problematic query execution to find out which actions cause poor performance.
3.Optimize queries by improving query execution plans.
Before you start analyzing and optimizing SQL queries, it’s essential to understand which queries require optimization. To determine this, you can use Microsoft SQL Server query optimization tools like SQL Server Profiler. It helps you trace queries received by the server, see the text of the queries, and check their execution times.
Please refer to this blog How to Optimize SQL Queries: Helpful Tips and Techniques, it show you detail steps and screenshots.
Hope this could help you.
