how to add bulk categories to all directory categories and subcategories ?

[softsoft]

i just launched my US Lawyers Directory i have more than 100 category and subcategory and i would like to add all US Stats "California,Texas,New York ..." to these categories and subcategories by using Database Query because if i do it manually it will take too much time.

How Can I Do It?
