Upcoming Webinar: Writing SQL Right on May 20

Coming up on May 20, I'll be delivering a webinar entitled Oracle SQL Performance: Writing SQL Right. Registration is now open. Once again the webinar will be hosted by Embarcadero and there will be two sessions - one at 10am ET and one at 2pm ET.

There are many ways to write a SQL statement that may lead to the functionally correct answer. However, we often get stuck in a rut using the same SQL syntax over and over even when there may be a better way to write the SQL to enhance performance. Some techniques worked great in previous Oracle versions but changes in the optimizer with the later versions made the behavior of those techniques change and, in many cases, regress.

This session covers a number of common anti-patterns that can be rewritten to provide enhanced performance and will help you learn how to:

  • Recognize certain patterns that can be sub-optimal. 
  • Analyze the "performance footprint" of certain patterns. 
  • Rewrite the anti-patterns to use less resources and take less time to execute. 

I look forward to "seeing" you there!
