You can probably do this in many ways, but the trick will be to keep the
amount of calls to the database to a minimum. With that in mind, here's a
first try . . .
<!--- all rows in oracle tables have a 'rowid' field --->
<cfquery name="get_all_ids" . . . >
select rowid
from sometable
</cfquery>
<!--- now choose the random numbers between 1 and get_all_ids.recordcount
--->
.... umm, you can look this up . . .
<!--- now use the random numbers to get your three records --->
<cfquery name="get_rand_records" . . . >
select field1, field2
from sometable
where rowid in ('#get_all_ids.rowid[randomnumber1]#',
'#get_all_ids.rowid[randomnumber2]#',
'#get_all_ids.rowid[randomnumber3]#')
</cfquery>

Subject: OT: Selecting records at random in Oracle
Hello all,
I don't know if this is possible but I was wondering if there was a way to
tell oracle (using cold fusion) that I wanted 3 records, but I didn't care
which ones they were. I guess a good analogy would be you load up a page
and you want to display a banner ad, but you don't care which banner ad you
display. Any help would be appreciated.
Thanks in advance,
Brandon Behrens
