ERROR 1194 (HY000): Table 'links' is marked as crashed and should be repaired

此问题我用什么命令修复呢？
表结构如下：
CREATE TABLE `links` (                                                           
          `id` int(11) NOT NULL auto_increment,                                          
          `url` varchar(200) NOT NULL default '',                                        
          `dt_insert` datetime NOT NULL default '0000-00-00 00:00:00',                   
          `dt_fetch` datetime default NULL,                                              
          `done` tinyint(4) NOT NULL default '0',                                        
          `html` longtext,                                                               
          PRIMARY KEY  (`url`),                                                          
          UNIQUE KEY `id` (`id`)                                                         
        )
