You may could not get information from the table in MySQL database, need to check the table status by mysqlcheck.

# mysqlcheck mysql_linuxfaq

mysql_linuxfaq.id                     OK
mysql_linuxfaq.name                   OK
mysql_linuxfaq.address                OK
mysql_linuxfaq.videos
Error    : Incorrect information in file: './ mysql_linuxfaq.videos/videos.frm'
error    : Corrupt

To repair a particular table, before doing that take a backup of table or Database

mysql>  use mysql_database;

mysql> repair table videos;
+---------------------------------+--------+------------+
| Table                  | Op     | Msg_type | Msg_text |

| mysql_linuxfaq.videos  | repair | status      | OK    |
