Can't find the answer to this anywhere so I thought I'd ask.

What's the easiest way to globally update the stock quantity.
I have around 500 products.
The products will never run out or will have different quantities so the easiest is to set all to '1'

What I don't want to do is go through each one individually and update the quantity.

Is there a way to do this via PHPMyAdmin (easy populate doesn't work for some reason).
