Database errors

WP admin area reported database needed repair. It attempted auto-repair and I get this:

wp_users: 1 client is using or hasn’t closed the table properly
wp_usermeta: 6 clients are using or haven’t closed the table properly
wp_posts: 8 clients are using or haven’t closed the table properly
wp_comments: 8 clients are using or haven’t closed the table properly
wp_options: Table is marked as crashed
wp_postmeta: 10 clients are using or haven’t closed the table properly
wp_terms: 3 clients are using or haven’t closed the table properly
wp_term_taxonomy: 6 clients are using or haven’t closed the table properly
wp_term_relationships: 6 clients are using or haven’t closed the table properly
wp_commentmeta: 8 clients are using or haven’t closed the table properly

How can I recover from this?

Thanks!
