need to set all products to taxable goods

[keylesslocks]

I need to set all my products to taxable goods... nI did thi in the phpmyadmin, it set everything to 1 but it didn't set everything to taxable goods

UPDATE zen_products
SET products_tax_class_id = '1'
WHERE products_tax_class_id = '0'

2 questions:

1. what did I do? if everything is set to 1 is it ok...
2. how do I do what I want to do?

thanks,

E
