copy the following code:

Code:
DROP TABLE IF EXISTS link_categories;
CREATE TABLE link_categories (
  link_categories_id int(11) NOT NULL auto_increment,
  link_categories_image varchar(64) default NULL,
  link_categories_sort_order int(3) default NULL,
  link_categories_date_added datetime default NULL,
  link_categories_last_modified datetime default NULL,
  link_categories_status tinyint(1) NOT NULL default 0,
  PRIMARY KEY  (link_categories_id),
  KEY idx_link_categories_date_added (link_categories_date_added)
) TYPE=MyISAM AUTO_INCREMENT=2 ;

INSERT INTO link_categories VALUES (1, 'link_category.jpg', 0, '2004-11-19 18:56:22', '2004-11-19 19:00:19', 1);
