SPM and GTTs http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:9548575600346056242 Howdy, I'm wondering about how SPM and things like https://blogs.oracle.com/optimizer/post/what-is-add-verified-spm would be impacted by the presence of global temporary tables within the query(s). I've been looking for documentation that would outline how SQL plan management would behave when dealing with queries relying on GTTs but I haven't had any luck so far. Basically I'm curious how reliably baselines, evolving, etc can/do work when dealing with queries that could have wildly different data sets based on GTTs within the query. Cheers,
