Learn how to formulate and tune SQL statements for optimal performance
This course takes a systematic approach to planning, analyzing, debugging and troubleshooting common query-related performance problems and will provide you with the skills necessary to write scalable, high performance SQL.
The SQL tuning methodology I used:

- Investigate whether alternative executon plans would be better.
- Update the SQL statement to push Oracle towards the better plan.
