Dependable, GeneratedByteCode, Activation, Dependent, CursorActivationpublic final class ConstantActionActivation extends BaseActivation
At compile time for DDL statements this class will be picked as the implementation of Activation. The language PreparedStatement will contain the ConstantAction created at compiled time. At execute time this class then fetches a language ResultSet using ResultSetFactory.getDDLResultSet and executing the ResultSet will invoke the execute on the ConstantAction.

Create the ResultSet tree for this statement.

Called by the class manager just after calling setGC().

Always return false since constant actions don't need recompilation
when the row counts change.
