Question

This is just a random question my friend asked me which I also do not know, yet I wanna know :/

Say I want to get this kind of result:

mytable_id      bar
    1        content2
    3        content1

from the tables below:

mytable

mytable_id            foo
    1              something1
    2              something2
    3              something3


yourtable

yourtable_id          bar
    2001           content1
    2002           content2
    2005           content3

Many thanks for the help 🙂

Answer 1

SELECT mytable.mytable_id, yourtable.bar FROM mytable, yourtable ORDER BY RAND() LIMIT 2

Well, as there is no relation between the two tables, you have to make a cartesian product, order the rows randomly and limit the output to the number of rows you want.
