cftransaction is supposed to wrap a group of querries that form a process.
Such as if someone was purchasing a product and three querries are used, one
to check the user/update user information, pull information from a shopping
cart, and submit the purchase data. you would lock each one of
True, transactions are not supported in MySQL. A CFLOCK would not create a
database transaction, and would not provide some of the benefits of
transactions such as rollback, but in this case it would have a similar
effect of making sure that no-one else was generating a new ID at the same
time.

that MySQl is only handling one request at a time... Here's some code that

No, CFLOCK restricts access to a chunk of code. The CFLOCK you suggested
should work, but won't you need to wrap READONLY CFLOCKs around every other
query for the database?
