I have a question regarding ColdFusion and database requests.
I have 2 applications on different servers, Server A and Server B and they both access a database on Server C. The problem is that recently that App1 on Server A and App2 on Server B ended up hitting the database at the same time. They both have identical code to insert a new record and whose ID is created by selecting a max id and incrementing it. They both ended up with the same ID. What is the best way to avoid this? I know that it is not possible to lock queries. If I wrap the queries in a CFTRANSACTION would that prevent this from re-occuring? Any help is greatly appreciated.
