Hi, You can't use aliases in a where, but you can in a HAVING clause. Regards Quentin -----Original Message----- From: Brad Barnett [mailto:[EMAIL PROTECTED]] Sent: Tuesday, 10 April 2001 8:44 a.m. To: [EMAIL PROTECTED] Subject: Strange queries SELECT url,newwebsites.description,newwebsites.title,newwebsites.catid,category.ful lname,MATCH newwebsites.description AGAINST ('aliens') as GOO from newwebsites,category LEFT JOIN userrestrictions ON userrestrictions.name REGEXP '[[:<:]]username|GLOBALAUTHADMIN[[:>:]]' AND newwebsites.catid=userrestrictions.catid where category.catid=newwebsites.catid AND userrestrictions.catid IS NULL AND category.groupid<='1' ORDER BY newwebsites.groupid DESC limit 10; Can anyone tell me why the above query works, and responds with a column labelled "GOO", but if I take the exact same query, and add "AND GOO > 0" to it, it complains that there is : ERROR 1054: Unknown column 'GOO' in 'where clause' What gives? If the column GOO exists when MYSQL does an output from that query, why can't I address it in the query? Thanks for any help anyone may have!
