是否可以只用一个SELECT随机订购“前n个”记录？

Question

Is there a way to do this without two selects ?

Original query

SELECT name,view_count  
FROM `ex`.`item` 
where status='available' order by view_count asc 
limit 40;

To display randomly

SELECT * 
FROM (SELECT name,view_count  
      FROM `ex`.`item` 
      where status='available' 
      order by view_count asc 
      limit 40 ) AS temp 
ORDER BY RAND();

Can this be done without a second select?
