[Star Wars] Would a planet-wide shield such as the one in Rogue One defend against the Death Star?

Let's say for whatever reason, they aim the Death Star at a shielded planet such as the one with archives. How many shots could it take? Would the shot be deflected or absorbed?

Alderaan had a planetary shield.  It lasted for less than a tenth of a second against the onslaught of the hypermatter beam of the Death Star's superlaser.

You can actually see this if you frame by frame the attack (at least in the special editions).  The beam splashes against the shield before overwhelming it completely.

So to answer your question:  Planetary shielding would be useless.
