run two queries consecutively
I have the following problem that I think would be fairly simple for any vet. I am a newbie so please bear with me.
I am writing a simple shopping cart using php mysql. I have reached a point where I need to run a query, then run another query to a different table based on the result of the first. This may need to happen more than once. Background. I have a table for my basket and a table for item descriptions. My basket query requests all records with a certain order_id number, this will contain the item_id. I wish to then query the item table to output the item description. I hope this is clear enough, I really need to know the best way of doing this.

If the two tables share a key (item_id), then you should be able to do a simple join to get the description in one query. Something like:
Code:
SELECT description FROM item_tbl, order_tbl WHERE order_tbl.item_id=item_tbl.item_id AND order_tbl.order_id=X
