best way to define a database with CAT/SUBCAT/SUB-SUBCAT.? rfung msg:3643613 7:07 am on May 7, 2008 (gmt 0) What is the best way to define a database structure that has:
which may have multiple subcategories
which in turn may have additional subcategories
..and this could go on for a few more levels (as a result of user input)
without creating a table for each subcategory since I don't know how far deep it would go?

CREATE TABLE `category` (`icat_id` bigint(64) unsigned NOT NULL auto_increment, `iparent_id` bigint(64) NOT NULL, `vcategory` varchar(250) NOT NULL, `vcaturl` text NOT NULL, `vrank` int(11) NOT NULL, `estatus` enum('0','1','3') NOT NULL, PRIMARY KEY (`icat_id`)) ENGINE=MyISAM
In this table , u can store as many subcat you want.
iparent_id will have its parent cat_id value. rfung msg:3644773 2:55 pm on May 8, 2008 (gmt 0)
Would you happen to know the typical way to query a table like this? how do i get all the subcats in a query in the manner as:
category subcat1 subcat2 category subcat12 category subcat12 subcat2 category subcat12 subcat21 category subcat13..etc
