What is the Index_asc hint?
I'm curious about the Index_asc hint in the context of database queries. Could you explain what it is and how it can be used to optimize query performance? I've heard it has something to do with the way indexes are scanned, but I'd like a more detailed understanding of its purpose and benefits.
