If what you basicaly want is just a tree structure, then it's done like that: CREATE TABLE something ( id INT AUTO_INCREMENT PRIMARY KEY NOT NULL, parent INT NOT NULL, data1 CHAR(255), data2 CHAR(255), ... ); Then you can specify the parent node id for each record in database. This is how tree-like structures are stored in SQL. Hope that helps. > I wanna setup a tree structure. Each node in this tree is a > table. Each table has a "link" field.
