SQL - RANDOM

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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

-   but if i generate rand id and then i use ,,select .... where id
	in(rand1, rand2, rand3), the query took only 0.0005 sec, but 		
	there is a problem that id doesnt exist


thanks for responses
