Weds 1st August 2012

This webinar has now finished, but feel free to click the button above to watch the recording.

Summary

Building on the previous Cost-Based Optimizer Basics webinar, in this almost "zero-slide" session we'll explore different aspects of the Cost-Based Optimizer that haven't been covered or only mentioned briefly in the 'basics' session.

This is a continuous live demonstration including topics like: Clustering Factor, Histograms, Dynamic Sampling, Virtual Columns, Daft Data Types and more. If you've ever asked yourself why a histogram can be a threat to database performance and why storing data using the correct data type matters regarding Execution Plans then this session is for you. It is recommended, although not required, to watch the recording of the 'basics' webinar first.

A live Q+A session with Randolf Geist will follow the presentation.
