Answer / david
You can optimize sql queries using dbForge Studio for MySQL:
1. Open a query file -> click the Query Profiling Mode button on the SQL toolbar -> the Query Profiler tool.
2. Execute the query by clicking the Execute button or F5. The Profiler document view opens. See the query profiling results displayed on three tabs - Profile, Plan and Status.
3. After you have made changes in the query, click the Get New Results button in the Profiler document view. New profiling results appear in the tree view as a new node with time and date of query execution. You can easily distinguish and navigate to them.
