All Implemented Interfaces:

Serializable

public class UniqueConstraintException
extends SecondaryConstraintException

Thrown when an attempt to write a primary database record would insert a secondary record with a duplicate key, for secondaries that represent one-to-one and one-to-many relationships.

When using the base API (com.sleepycat.je), this can occur when a SecondaryDatabase is not configured to allow duplicate keys (which is the default, see DatabaseConfig.setSortedDuplicates(boolean)). This implies the use of a one-to-one or one-to-many relationship.

When using the DPL (com.sleepycat.persist), this can occur when a SecondaryKey is defined with a Relationship.ONE_TO_ONE or Relationship.ONE_TO_MANY relationship.

The Transaction handle is invalidated as a result of this exception.

Since:

4.0
