Select ID 是“随机”的东西

Question

I already searched for random ID. It seems I HAVE to select a random row? I don't quite understand it yet.

What I want to do is to select tid , preis from the stickythread from a random ID or row.

$sql="SELECT tid,preis FROM stickythread WHERE id=1";

Is there a simple way to get a random ID from 1 to 3, without changing to much?

Answer 1

I thin that you mean:

select tid, preis 
from stickythread 
where id between 1 and 3 
order by rand() limit 1

The query filters on id between 1 and 3 , then order by rand() shuffles the results, and limit 1 keeps the first row only.
