Home -> Community -> Mailing Lists -> Oracle-L -> RE: Creating sequences on the DUAL table?
Sounds like your developer hangs out with some of our developers! ;)
I am sorry to say but, I guess the syntax "...from dual" could be confusing to the developer.
Your understanding is just fine. Don't do anything with dual..
May be briefly explaining to the developer how sequence number work could take care of this request.
Good Luck..

I have a request from one of our developers to create two new sequences on the DUAL table.
This seems like a bad idea to me. I've never had such a request in the past. I asked for clarification on why this is needed and I didn't get a lot of details yet.
Is this something that is standard operating procedure? My understanding that interfacing with the DUAL table is usually inviting poor performance. Plus, I don't like to mess around with system tables, in general.
Under what circumstances would it be justified to create sequences on the DUAL table? Should I just flat-out refuse this request and if so, why?
Thanks,
