Need help adding fields using MySQL

I am using a MySQL DB to manage employees. I maintain the DB in PHPMyAdmin. I want to add 70 new fields into a table by using SQL. I thought this would work. Can you tell me why it doesn't

CREATE TABLE IF NOT EXISTS `dist` (

You are using CREATE TABLE. You should be using ALTER TABLE if you want to add fields. PHPMyAdmin should be showing you an error indicating that the table already exists.
