Database needs repairing

Hi,

When I logged in today my site told me the database needed to be repaired. I turned it on via wp-config.php and I received the following errors:

wp_posts: 2 clients are using or haven’t closed the table properly
wp_options: Table is marked as crashed
wp_postmeta: 5 clients are using or haven’t closed the table properly
wp_term_relationships: 1 client is using or hasn’t closed the table properly
