How do I add an APN via ADB?

For hardware reasons (My menu key doesn't work) I can not add an APN via settings. I read [here](https://groups.google.com/forum/#!topic/android-platform/yMvPJr6Aoq4) about using sqlite and [here](https://stackoverflow.com/a/7869387/2711378) about using code. But I need a more convenient way to do it. I need to do it using adb.
