I have already got a unique constraint on the data table.  But, when
inserting a new record, if a duplicate exists, wouldn't the system simply
error out due to the duplicate and not rerun the ID statement to recreate
the ID?

Why not place a unique constraint on your companyID field in your database?
Do you need to randomly select a company from your company table?  If so, I
have a cool way of doing that via a SQL Select statement.

Thanks

Subject: Random Number Generator...

I am currently running a random number generator and assigning it to a
variable as follows:
        
        <cfset CompanyId = #LCase(Left(form.CompanyName,2))# &
#RandRange(100, 999)#>

The problem is that there will always be the possibility of duplication.  I
would like to run a <cfquery... to extract the Company IDs from the table in
order to double check for duplication.  If a duplication is found, how can I
cause the random number generator to run again and recheck for duplication
without reloading the entire page?
