for building my website i am implementing a tree-style data organization. for that i have a mysql table called 'jm_tree': CATID, int(10) auto_increment -> Index PARENT, int(10) ->the CATID of the 'parent' node TEXT, varchar(40) -> small description TYPE set('FOLDER','FILE','LINK','POST') -> the type of object
and for each TYPE of object i have a corresponding table like : ex.: for a TYPE 'FILE' i have a 'jm_files' table [ that has the CATID field also ( as a FK ) ] with all the files related to that node. i want to know is ( and i am perfectly aware that this in possible using multiple queries and PHP ) if it's possible that in one MySQL query to INNER JOIN the 'jm_tree' table to the specifical table ( jm_files, jm_links, fo fo fo ) according to the contents of the 'jm_tree.type' 99%-possibility-of-being-wrong-something-like-example :) SELECT * FROM jm_tree INNER JOIN jm_files IF jm_tree.type='FILE' INNER JOIN jm_links IF jm_tree.type='LINKS' Best Regards, José Moreira Técnico de Informática | IT Technician Vila Nova de Gaia, Portugal E-mail: [EMAIL PROTECTED] MSN: [EMAIL PROTECTED] ICQ: 136936120 IRC: gray (irc.ptnet.org)
