Now I receive all of this data every day and I need to delete all of the previous data each time and insert the new one. In order to create the category table (tree table) I want to create an array out of the categories information at the products and then insert it into the the categories table (the tree :)). I also thought about retrieving the data from the products table and inserting it first into a temporary table and from that information create the categories table (tree :)), but I prefer to save the next selects from that table and just create an array. Maybe you or anyone else got a better idea? Thanks again!
