Use the HAVING clause: SELECT part.memberid, part.prefname, part.email, COUNT(*) AS numberofans FROM tblparticipants part LEFT JOIN tblanswers answer ON (answer.par_num=part.memberid) LEFT OUTER JOIN profilepdfauth pdfauth ON (part.memberid=pdfauth.memberid) WHERE pdfauth.id IS NULL GROUP BY part.memberid HAVING count(*) >=31 ORDER BY numberofans DESC, part.memberid;
"Peter Lauri" <[EMAIL PROTECTED]> 07/26/2006 09:58 AM To <mysql@lists.mysql.com> cc Subject WHERE problem, or is it a problem? Best group member, I have this query on MySQL version 4.0.27: SELECT part.memberid, part.prefname, part.email, COUNT(*) AS numberofans FROM tblparticipants part LEFT JOIN tblanswers answer ON (answer.par_num=part.memberid) LEFT OUTER JOIN profilepdfauth pdfauth ON (part.memberid=pdfauth.memberid) WHERE pdfauth.id IS NULL GROUP BY part.memberid ORDER BY numberofans DESC, part.memberid; This works fine, However, I only want the results where COUNT(*)>=31. So I tried: SELECT part.memberid, part.prefname, part.email, COUNT( * ) AS numberofans FROM tblparticipants part LEFT JOIN tblanswers answer ON ( answer.par_num = part.memberid ) LEFT OUTER JOIN profilepdfauth pdfauth ON ( part.memberid = pdfauth.memberid) WHERE pdfauth.id IS NULL AND COUNT( * ) >=31 GROUP BY part.memberid ORDER BY numberofans DESC , part.memberid But then MySQL answered with: #1111 - Invalid use of group function What is the problem here? Why can I not do a WHERE COUNT(*)>=31? Is there any other way to just select the COUNT(*)>=31?
