Hi,

i would ask what is the best method for random select from database. I have table with 20k items..

-   If i use ,,select * from table order by rand() limit 3", the query
    took 0.0524 sec ... its slightly enough

and as your table grows in size, it gets slower and slower.

Try this:

There are other suggestions out there too, search for "mysql don't use random()".
