Constructor Details

TriggerNewTransitionRows

public TriggerNewTransitionRows()
                         throws 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:

SQLException - thrown if no trigger active
