Things get much more interesting in a multithreaded environment. You cannot be sure that before the second selection, another thread does not increase the sequence by 100 again. This problem can be solved by synchronizing access on the Java side: only allow one thread to start fetching IDs at a time.

The situation becomes really difficult when you can’t synchronize because parts of the application don’t run on the same JVM, or even on the same physical machine. I found some references in forums that others also have problems solving this problem, but none of the answers really work not to mention being reasonable.

Also, this way is much more efficient. Selecting nextval from a sequence is a highly optimized operation in Oracle, while running ddl to alter the sequence is much more expensive.

However, the most common way to relate two tables is through a numeric type field that the database engine itself takes care of generating for us: these are the auto-numeric values also known as auto-incremental numeric.

An auto-numeric type field normally starts at 1 with the first record, and each time a new record is inserted the database engine increments its value by one, the new records being 2, 3, 4 and so on.

The good thing about doing it this way is that the database engine itself takes care of creating it and frees us from the problem of managing it ourselves. Achieving this is much more complicated than it sounds. In an environment with a heavy workload, where new records are being entered all the time, creating this auto-numeric is not easy because we have to make sure that the same one is not assigned to more than one record, that they are always in order and without gaps, that no blockages occur when trying to enter two records at the same time… And the database engine saves us all this work, great!
