Can we use parallel hint in delete statement?
Excuse me, I was wondering if I could ask you a question about SQL and specifically the use of parallel hints in delete statements. I've heard that parallel processing can greatly enhance the performance of database operations, but I'm unsure if it's appropriate or even possible to apply this concept to delete statements. Could you clarify whether we can indeed utilize parallel hints in delete statements and, if so, how we might go about doing so? I'm curious about any potential benefits or drawbacks to this approach and any best practices you might recommend. Thank you for your time and consideration.
