If by revolving you mean going around the sun, and let me assume it continued to rotate on its axis, we would still have the daily solar and lunar tides! exactly same as when the earth was revolving normally.
Tides are caused mainly by the rotation of the earth which makes the water body (oceans) on it "point to" the moon and the sun, and move relative to the solid surface of the earth.
This relative motion "brakes" the earth's rotation, slows it down, speeds up the moon in its orbit in return, and pushes it (the moon) away at 4 cm / year!
