if you have multiple servers, CFTRANSACTION will work fine,
placing the requisite locks as needed.
My problem with it is that if you put 3-4 queries inside a CFTRANSACTION

That can be desired behaviour if the alternative is inconsistent data.

DB Server for it to handle the transaction properly
Maybe for MS SQL Server, but databases that do better than row level
in fact, it said Access, so TSQL is not really an option and
I don't know what transaction mechanism it uses
Ah, I missed that, and not knowing the latest Access, I don't even know
if it has any form of TSQL
I have a tendency to avoid CFTRANSACTION because of the overhead, and

I don't see why you'd say it's any easier, really. It's easy enough to do
this in a stored procedure:
BEGIN TRANSACTION
... your SQL DML statements ...
COMMIT TRANSACTION

Yes, but just think of the savings in angle brackets!

I'm having trouble seeing why you need a loop for this?? Can you explain?
From your description I would think you'd follow these steps (conditional
statements and not loops):
1) set your random number (as you have)
2) run a query to see if that number is used in either table (simple SELECT
The CreateUUID() might be usefull if you don't need it to be an int.
Otherwise I would create an other table to produce your key
like ...
[index_table][key]
/ \
/\
[table1][key] [table2][key]

Eventually though..this will cause a page to loop many times.. and run
the Query many times increasing load time and processor time.
