Answer 1

Not sure why you are joining on @rownum, it might be messing with your result set. Try taking it out and see if it works.

Your inner join looks ok, except I have never seen it with the wrapped parens, but I suspect it will work as expected. To test your query you could remove the complicated where clause and just put something like where tour_foreign.id = 1.

Something like:

SELECT
    tf.*
FROM 
    tour_foreign AS tf
INNER JOIN
    tour_foreign_residence AS tfr
ON
    tfr.relation = tf.id
WHERE
    tf.id = 1

I implemented aliases for your longer table names (tf, and tfr) as they are easier to work with.

Answer 2

Try using GROUP_CONCAT() to join the names from you tour_foreign_residence table
