Re: Selecting Next X Values From Dual
If X is fixed for all sessions, do a step increase of X so that you only have to select 1 row from dual. Anjo. On Friday 27 September 2002 00:18, you wrote: All...

Re: Selecting Next X Values From Dual
Anjo... Thanks for the reply!! If X is fixed for all sessions, do a step increase of X so that you only have to select 1 row from dual. Unfortunately, I don't feel I can do that. I'm using the returned values as unique identifiers to protect against duplicate database submissions from a web-based application. I have implemented a workaround by selecting a row from dual X number of times. I wanted something a bit cleaner, and [seemingly] less database-intensive than querying in a loop.

RE: Selecting Next X Values From Dual
I created a package that would easily loop thru and select x number of entries, but not return them in a select to you. This way, you can make 1 simple call passing it X. Is that what you wanted ??? Or do you have to have them as returned values of a select ? Kevin -Original Message- Sent: Friday, September 27, 2002 2:38 PM To: Multiple recipients of list ORACLE-L Anjo... Thanks for the reply!!
