Class TriggerNewTransitionRows

java.lang.Object
  org.apache.derby.vti.UpdatableVTITemplate
      org.apache.derby.catalog.TriggerNewTransitionRows

All Implemented Interfaces:

java.sql.PreparedStatement, java.sql.Statement, java.sql.Wrapper

public final class TriggerNewTransitionRows
extends UpdatableVTITemplate

Provides information about about a a set of new rows created by a trigger action.

This class implements only JDBC 1.2, not JDBC 2.0. You cannot compile this class with JDK1.2, since it implements only the JDBC 1.2 ResultSet interface and not the JDBC 2.0 ResultSet interface. You can only use this class in a JDK 1.2 runtime environment if no JDBC 2.0 calls are made against it.

Constructor Detail

TriggerNewTransitionRows

public TriggerNewTransitionRows()
                         throws java.sql.SQLException

Construct a VTI on the trigger's new row set. The new row set is the after image of the rows that are changed by the trigger. For a trigger on a delete, this throws an exception. For a trigger on an update, this is the rows after they are updated. For an insert, this is the rows that are inserted.

Throws:

java.sql.SQLException - thrown if no trigger active
