Note An empty result set is not the same as a null value. For a scrollable cursor, all the rows in the result set are returned to the calling batch, procedure, or trigger when the procedure exits. When returned, the cursor position is left at the position of the last fetch executed in the procedure.
The wall sit strengthens your lower body. Your quadriceps on the fronts of your upper legs remain in a static contraction to support the wall sit. The hamstrings on the backs of your upper legs also remain contracted as you sit. Your glutes contract during the wall sit to keep your body stable and balanced.
Thigh exercises will not burn calories like cardio or interval training, but it will give them a lean appearance. Wall squats and plie squats are a couple of the best because they work all of your major leg muscles. A wall squat is an isometric exercise, where your body remains stationary throughout the exercise. Place your back against the wall and bend your knees to a 45-degree angle. Hold for 30 seconds, and then rest. Repeat for four sets of 10 reps. Do a plie squat by planting your feet wider than shoulder-width and placing your hands on your hips. Bend your knees and lower your buttocks, until your thighs are parallel to the floor, then push up to the starting position. Do four sets of 10 reps.
