database errors

Today when i tried to login to my WordPress dashboard, i got an error that wrote “there is problem in database tables”, when i opened homepage of website i got this error ” can not establish a connection to database”
i added this line to wp-config.php
“define(‘WP_ALLOW_REPAIR’, true);”
WordPress itself fixed the issue and website came back to normal service again but at end of repair page i got theses messages:

“wp_usermeta: 1 client is using or hasn’t closed the table properly
wp_posts: 2 clients are using or haven’t closed the table properly
wp_comments: 2 clients are using or haven’t closed the table properly
wp_options: Table is marked as crashed
wp_postmeta: 2 clients are using or haven’t closed the table properly
wp_terms: 1 client is using or hasn’t closed the table properly
wp_term_taxonomy: 2 clients are using or haven’t closed the table properly
wp_term_relationships: 1 client is using or hasn’t closed the table properly”

I’m worried that these errors make a big problem in the future
Does anyone here can help me to fix this problem?
