Hello.. This tells me, that it is "invalid use of group function" .. what I want to do is to make sure, that when I count my log for clicks and shows of the banner, there has to be fewer rows with the bannerid=b.id in the log, than the fields b.maxklik and b.maxhits says (so I can set e.g. 6000 clicks or 50000 shows for a banner)..
Can you help with a mysql query that should work??
EDIT 2:
Same error

You can't use aggregate functions in the WHERE clause - only the HAVING. I did my best to re-write your query as:
SELECT b.id as b_id
FROM BANNER b
JOIN BANNERHITS bl ON b.id = bl.bannerid
AND bl.userid = '".$this->userid."'
JOIN BANNERHITS blog ON b.id = blog.bannerid
JOIN BANNERKLIK bk ON b.id = bk.bannerid
WHERE ( b.placement = '".$place."'
AND b.usertype IN ('".$usertype."', '')
AND b.userpostalcode LIKE ',".$postcode.",'
AND (b.userage LIKE ',".$ageYears.",' OR b.userage IS NULL)
AND b.maxviewsprday IS NULL)
OR remainingshow = '1'
GROUP BY bl.id, bk.id, blog.id
HAVING b.maxhits > count(blog.id)
AND b.maxklik > count(bk.id)
AND b.maxviewsprday > count(bl.id)
ORDER BY remainingshow ASC
LIMIT 1
You appear to have a syntax error here:
AND b.maxklik > count(bk.id) ".$ubid.")
I don't know how you want to incorporate the $ubid variable into the query...
