Examples of NativeSequence

oracle.toplink.essentials.sequencing.NativeSequence

Purpose: Define a database's native sequencing mechanism.
Description Many databases have built in support for sequencing. This can be a SEQUENCE object such as in Oracle, or a auto-incrementing column such as the IDENTITY field in Sybase. For an auto-incrementing column the preallocation size is always 1. For a SEQUENCE object the preallocation size must match the SEQUENCE objects "increment by".
