Ok I recently just added my whole yu-gi-oh tcg collection into a mysql database so I can keep track of what i have, what set they’re from and the rarity.
I know there are a couple that have identical entries, so is there a single mysql query that I can just pull these out (like name=name set=set rarity=rarity) without manually looping through my whole database (considering its it 137 cards now, but will be 500+ by the end of next week)
