Extending the IldRequest Class

It is not possible to derive from the class IldRequest because the actual objects handled by your application are not instances of the IldRequest base class but instances of subclasses of this class.

If, for any reason, you need to extend the functionality of the Rogue Wave DB Link class IldRequest, you can retrieve the determining part for handling statements.

The member function IldRequest::getHook returns it as a void pointer (IlAny). The actual return value depends on the target RDBMS, as shown in Table 4.5:
