You cannot get that kind of results as distinct and separate columns. Have
you looked at the GROUP_CONCAT() function as a work around?
SELECT t1.date, t1.val, GROUP_CONCAT(t2.val)
FROM t1
RIGHT JOIN t2
on t1.date = t2.date
where t2.date between '2005-08-01' and '2005-08-14'
and t1.uid = 'me'
GROUP BY t1.date, t1.val;
