Hi All,
The application I am in charge of has been optimized to use the rule based optimizer. I've been doing some tracing and would like some clarification.
What is the difference between a UNIQUE SCAN and a RANGE SCAN?
I'm lost as the to differences. Even the documentation does not really tell me the difference between them.
Thanks,
