  We systematically study supersymmetry breaking with non-vanishing F and D
terms. We classify the models into two categories and find that a certain class
of models necessarily has runaway behavior of scalar potential, while the other
needs the Fayet-Iliopoulos term to break supersymmetry. The latter class is
useful to have a simple model of gauge mediation where the vacuum is stable
everywhere and the gaugino mass is generated at the one-loop order.
