Class SequenceManagerNativeImpl

java.lang.Object
  extended by org.apache.ojb.broker.util.sequence.AbstractSequenceManager
      extended by org.apache.ojb.broker.util.sequence.SequenceManagerNativeImpl
All Implemented Interfaces:
SequenceManager

public class SequenceManagerNativeImpl
extends AbstractSequenceManager

Sequence manager implementation using native database Identity columns (like MySQL, MSSQL, ...). For proper work some specific metadata settings needed:

Note: Make sure that the DB generated identity columns represent values > 0, because negative values intern used by this implementation and 0 could cause problems with primitive FK fields.

Implementation configuration properties:

Property Key Property Values
no properties to set
