Interface TargetResultSet

All Superinterfaces:

ResultSet

All Known Implementing Classes:

InsertResultSet

public interface TargetResultSet
extends ResultSet

The TargetResultSet interface is used to provide additional operations on result sets that are the target of a bulk insert or update. This is useful because bulk insert is upside down - the insert is done via the store.
