Class ERXSequence.NativeDatabaseSequence

java.lang.Object

er.extensions.eof.ERXSequence

er.extensions.eof.ERXSequence.NativeDatabaseSequence

Enclosing class:

ERXSequence

public static class ERXSequence.NativeDatabaseSequence
extends ERXSequence

NativeDatabaseSequence uses ERXSQLHelper.getNextValFromSequenceNamed to generate a sequence value using your database's native sequence generation scheme. This will fail if ERXSQLHelper.getNextValFromSequenceNamed is not implemented for your database. This is also currently limited to only incrementing 1 at a time.
