With really good drainage, modern pressure treated poles will last a hundred years. Drainage is always the key. Here in East Texas, where I have red clay, aggressive bugs and a lot of humidity, all other wood rots out very quickly if it touches the ground. An oak just laying on the ground isn't worth cutting up for firewood in a year because of how quickly it rots. Your white oak might be different then the dozen or so different types of oak trees that I have, but I wouldn't trust it to last very long.
