Table is marked as crashed and should be repaired

Today I did start to get error on webshop, shop has always working good.
No Changes has been made.
And I dont know how to repair:(

Fatal error: 145 - Table './dbrpitbi_dbr2016/lc_visitors' is marked as crashed and should be repaired select id from dbrpitbi_dbr2016.lc_visitors where uid = '57c519afb70e0' and date(date_updated) = '2016-08-30' limit 1; in ~/includes/library/lib_database.inc.php (Line 298)

Did a repair table in data base and now it works :) Dont know if its the right way to do:)

For those who don't know how to.

MySQL Query:

REPAIR TABLE tablename USE_FRM

http://dev.mysql.com/doc/refman/5.7/en/repair-table.html

Or in phpMyAdmin, mark the table as checked and select Repair table.
