MySQL Left Join + Min

Question

Seemingly simple MySQL question, but I\'ve never had to do this before..

I have two tables, items and prices, with a one-to-many relationship.

Items         


        

Answer 1

This will return multiple records for a record in Items if there are multiple Prices records for it with the minimum price:

select items.id, items.name, prices.price, prices.id
from items
left join prices on (
    items.id = prices.item_id 
    and prices.price = (
        select min(price)
        from prices
        where item_id = items.id
    )
);
