How do you wire a switch receptical outlet with no other fixture.?

The Wording of your question is a bit difficult to understand. I'm not sure what you mean by a "switch recepticle outlet."

If you mean a switch/receptacle combination device, and you want the switch to operate the receptacle, first you must remove the brass bar that connects the two brass screw terminals. This can be easily done with any set of pliers small enough to get hold of the bar. By moving it back and forth a few times it will simply come off.

Next connect your green or bare wire to the ground screw of the device. Then connect your neutral coming into the box to the nickle (or silver) screw terminal next to the receptacle. Then connect a black wire (or any color wire other than white, gray, green, or orange) from the switch leg terminal of the switch (most likely a black screw) to the brass terminal of the receptacle. Make this wire long enough to work with. There is no reason to make it so short you can't work with it if trouble shooting is ever necessary.

And finally connect your hot wire coming into the box to the brass terminal on the switch.

If all this makes absolutely no sense to you, find a competent electrician to do it for you. We do these kinds of things in our sleep. (Just kidding, of course.)
