i think the newer versions of MYSQL allow for subselects and I think that is what you want. see www.mysql.net -----Original Message----- From: mayo [mailto:mayo@xxxxxxxxxxxxxxxxxx] Sent: Sunday, February 15, 2004 11:56 PM To: php-db Subject: sql, problem with join and presentation Currently I display a list of classes. Simplified SQL and display below: SELECT * FROM classes WHERE classCategory='$Category' AND classDeleted=0 ORDER BY $order $reorder The presentation is: +------------------+----------+------------+ | CLASS TITLE | LOCATION | CLASS CODE | +------------------+----------+------------+ | CLASS DESCRIPTION <br/><br/> | | CLASS INSTRUCTOR <br/><br/> | | CLASS TIME | +------------------------------------------+ Now, things are getting a little more complicated. Each class is going to have sections. So the display will be: CLASS TITLE CLASS DESCRIPTION CLASS CODE : CLASS SECTION .. LOCATION .. CLASS TIME .. INSTRUCTOR example (simplified) +---------------------------------------------+ | INTRO TO AAA | +---------------------------------------------+ | This is a really interesting .... | | | +---------+-----+------------+----------------+ |HT-111:A | NYC | 12:00-4:00 | Albert Alkin | |HT-111:B | JC | 2:00-6:00 | Bob Bailey | |HT-111:C | BX | 4:00-8:00 | Chris Cawley | +---------+-----+------------+----------------+ I'm having a really hard time coming up with the sql for this. I want to (pseudo) select * from classes and classSections where classDeleted=0 and group by classCode tables below CLASSES classID classDescription classTexts classCost classDeleted CLASSCODES classCodeID classID classCodeSection classDate classTime classLocation classInstructor I'm going nuts trying to get this. I must be missing something simple.
