Indeed you can my good sir :)
Im going to insert into one table a list of about 3.5 million products
each day, thouse products also contain data about their own categories.
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!
