There are many options: many need the water shut off and the water drained from the copper pipe.

Repair Clamp

A mechanical repair clamp that is put on top of the leaky area. Pay a visit to a hardware store or plumbing supply. This really should be regarded as temporary fix.

Adhesive Patch

A variety of compounds, many epoxy based, may be put on the leaky area after the water is off and the pipe is drained, and the outside pipe surface is cleaned up well to removed dirt, dust bunnies, and corrosion. These are also available in the plumbing section of a hardware store

Coupler repair

Patch the pipe with a coupler. If you need to mend a puncture quickly and properly but you don"t have any replacement pipe on hand – just a coupler and solder, that"ll do just fine. Cut the pipe on top of the pinhole leak so the pipe splits in two. De-burr the edge, and clean the edge. Apply your flux to both ends of the pipe and attach the coupler – then hit it with your torch and apply solder. This repair isn"t really as good as replacing the pipe – but it"s the next best solution.

Switch out the pipe

With a single pinhole, there are very likely others that will be coming, Copper pipe is easy to replace with some essential soldering skills, but call a plumber if in doubt. I would take out the defective area and inspect the inside carefully to figure out the scope of the corrosion and how much should be replaced.
