mysql随机从前10名

Question

I have the mysql query:

SELECT * FROM bigtable WHERE column1='1' ORDER BY column2 DESC LIMIT 10

And then I put everything in an array and use php to choose a random row from this array of 10 items.

Is there a way to do this with a single mysql query instead of mysql+php part?

Answer 1

After take top 10, then take 1 with random:

SELECT * from (
   SELECT * FROM bigtable 
   WHERE column1='1' 
   ORDER BY column2 DESC LIMIT 10
) T ORDER BY RAND() 
LIMIT 1
