join with incomplete data problem

Hi all,

 

I'm trying to retrieve information in a single mysql command to generate information for a pdf file.  This requires a total list of items in a sale, and also displayed alongside will be offers made prior the sale.

 

I have two tables, one has around 200 items, called bid_auctions, and the other called bids.  bid_auctions has an entry called bid_offer, and simply indicates 0 or 1, depending on whether the item has (1) or hasn't (0) had a bid placed on it.  the second table (bids) has information such as bid_amount, bid_id (the id number from bid_auctions).

 

I need to list all items, and if they have a bid, list that info too.  I can't seem to find any info about joining where there is an 'if' statement, eg join bids if bid.id_offer = bid_auctions.id....

 

Help  :-[

 

Update: I've found that I can do if in mysql, however, can't figure out how to do an if.. join statement...
