用於創建wordpress數據庫表的MySQLDB代碼

我需要使用連接到mysql服務器但使用SQLAlchemy代碼的mysqldb創建wordpress數據庫。該表的SQL如下：用於創建wordpress數據庫表的MySQLDB代碼

CREATE TABLE IF NOT EXISTS `wp_links` (
    `link_id` bigint(20) unsigned NOT NULL auto_increment, 
    `link_url` varchar(255) NOT NULL default '', 
    `link_name` varchar(255) NOT NULL default '', 
    `link_image` varchar(255) NOT NULL default '', 
    `link_target` varchar(25) NOT NULL default '', 
    `link_description` varchar(255) NOT NULL default '', 
    `link_visible` varchar(20) NOT NULL default 'Y', 
    `link_owner` bigint(20) unsigned NOT NULL default '1', 
    `link_rating` int(11) NOT NULL default '0', 
    `link_updated` datetime NOT NULL default '0000-00-00 00:00:00', 
    `link_rel` varchar(255) NOT NULL default '', 
    `link_notes` mediumtext NOT NULL, 
    `link_rss` varchar(255) NOT NULL default '', 
    PRIMARY KEY (`link_id`), 
    KEY `link_visible` (`link_visible`) 
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=8 ;

這是我寫的做同樣的事情的Python代碼：

wp_links = []#links table 
wp_links.append (Table ('wp_links', metadata, Column ('link_id', BIGINT(20, unsigned=True),nullable=False, primary_key=True), 
         Column('link_url', VARCHAR(255), nullable=False, server_default=''), 
         Column('link_name', VARCHAR(255), nullable=False, server_default=''), 
         Column('link_image', VARCHAR(255), nullable=False, server_default=''), 
         Column('link_target', VARCHAR(255), nullable=False, server_default=''), 
         Column('link_description', VARCHAR(255), nullable=False, server_default=''), 
         Column('link_visible', VARCHAR(20), key='link_visible', nullable=False, server_default='Y'), 
         Column('link_owner', BIGINT(20, unsigned=True), nullable=False, server_default='1'), 
         Column('link_rating', INTEGER(11), nullable=False, server_default='0'), 
         Column('link_updated', DATETIME(), nullable=False, server_default='0000-00-00 00:00:00'), 
         Column('link_rel', VARCHAR(255), nullable=False, server_default=''), 
         Column('link_notes', MEDIUMTEXT(), nullable=False), 
         Column('link_rss', VARCHAR(255), nullable=False, server_default='')))

它轉換爲下列SQL：

CREATE TABLE IF NOT EXISTS `wp_links` (
    `link_id` bigint(20) unsigned NOT NULL auto_increment, 
    `link_url` varchar(255) NOT NULL default '', 
    `link_name` varchar(255) NOT NULL default '', 
    `link_image` varchar(255) NOT NULL default '', 
    `link_target` varchar(255) NOT NULL default '', 
    `link_description` varchar(255) NOT NULL default '', 
    `link_visible` varchar(20) NOT NULL default 'Y', 
    `link_owner` bigint(20) unsigned NOT NULL default '1', 
    `link_rating` int(11) NOT NULL default '0', 
    `link_updated` datetime NOT NULL default '0000-00-00 00:00:00', 
    `link_rel` varchar(255) NOT NULL default '', 
    `link_notes` mediumtext NOT NULL, 
    `link_rss` varchar(255) NOT NULL default '', 
    PRIMARY KEY (`link_id`) 
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

注意不同之處，行「KEY link_visible（link_visible）」不存在。如何糾正我的Python代碼以使它們相同？
