Should each and every table have a primary key?

Question

I\'m creating a database table and I don\'t have a logical primary key assigned to it. So, I\'m thinking about leaving it without a primary key, but I\'m feeling a bit guilt

Answer 1

I know that in order to use certain features of the gridview in .NET, you need a primary key in order for the gridview to know which row needs updating/deleting. General practice should be to have a primary key or primary key cluster. I personally prefer the former.
