depends how much you put in. A little diesel in petrol would result in a very smokey exhaust, too much diesel and the engine would not run. You would need a complete drain of the system, and then refill. A little petrol in diesel again would do no real harm, too much and the engine again would not go and need a complete drain and refill. If you realise you have done this in a filling station and have put any more than about 5% mix in then do not start the engine
