Did you read the documentation?

       [--if-exists] destroy table record...
              Deletes each specified record from table.  Unless --if-exists is
              specified, each records must exist.

       --all destroy table
              Deletes all records from the table.

              Caution (ovs-vsctl as example)
                     The destroy command is only useful for records in the QoS
                     or  Queue  tables.  Records in other tables are automati‐
                     cally deleted from the database when they become unreach‐
                     able from the Open_vSwitch table.  This means that delet‐
                     ing the last reference to  a  record  is  sufficient  for
                     deleting the record itself.  For records in these tables,
                     destroy is silently ignored.  See  the  EXAMPLES  section
                     below for more information.
