Judgments on the pleadings, and summary judgments, are final judgments and shall be rendered and signed in the same manner and with the same effect as if a trial had been had upon evidence regularly adduced. If the judgment does not grant mover all of the relief prayed for, jurisdiction shall be retained in order to adjudicate on mover’s right to the relief not granted on motion.

An appeal does not lie from the court’s refusal to render any judgment on the pleading or summary judgment.
