Nice question, I would also like to know this.

Btw, why do you want to create a new partial index which is already covered by a regular index? Do you want to remove that regular index after creating the partial one?

Hey guys, 

Just a quick general question around index creation. 

When creating a partial index on a fairly large table (200gb) where an index already exists that would satisfy the partial index criteria would there still be a scan of the entire table or will it use the existing index when creating the new one? 

Hope the question make sense.
