Narrative:

Climbing out of cvg we received a right engine oil pressure warning. Ran the QRH procedure. At low power settings the warning cleared. Talked to dispatch and maintenance control. We elected to turn back to cvg. Passenger and flight attendant were notified that we had an engine indication out of normal parameters and were returning to cvg. We declared an emergency. Cvg approach cleared us for a visual. At idle power the right engine oil pressure warning returned. Ran the QRH procedure again, the oil pressure warning remained. So as per the QRH single engine procedure, the #2 engine was shut down. Notified ATC of single engine approach. On base to final, the flight attendant notified us that there might be smoke in the cabin. We requested he check for location of smoke and if there was any odor. He promptly called back to say there was smoke near the floor, but no odor. We landed uneventfully, confirmed the smoke was air conditioning and taxied to the gate. Callback conversation with reporter revealed the following information: the reporter stated when on the ground when the cowling was opened, then engine was covered with oil. The reporter said the loss of oil pressure and qty was caused by a main oil pump failure or the oil line connection at the main oil pump.
