Could someone please tell me what sql code that I need to run in my database to reverse and remove the following as I don't have a clue:

ALTER TABLE newsletters ADD template varchar(64) AFTER locked;
CREATE TABLE `newsletters_to_products` (
`newsletter_id` INT( 11 ) DEFAULT '0' NOT NULL ,
`products_id` INT( 11 ) DEFAULT '0' NOT NULL ,
PRIMARY KEY ( `newsletter_id` , `products_id` )
);

I need to reverse the first line and remove the table newsletter_to_products

Many thanks
