Hello, everybody my problem is the following: I just imported a csv file to a MySQL database that contains name and email fields. It has about 9k lines on it and I need a new field that orinally didn't exist called "code" thats suposed to be MD5(name.email) I know how to do this for new data, but I don't know how to update all the old ones I already have there.
