Get articles with max date only

Question

Hello Everyone
I've got a little problem with a sql query. I got two tables and a lot of articles. The articles are listed multiple times and got different dates. I want to select the following rows:
p.productname
i.amount
i.date
The problem is, that every product only should be listed one time (something like UNIC or DISTINCT). And it should be the product with the highest date. Is there something like MAX(date) that I can use?
What I already have is...
SELECT
    p.productname,
    i.amount,
    i.date
FROM op_inventory i
LEFT JOIN products p
ON p.ItemID = i.fk_article
Now, how can I solve my problem above?...

Hmm, thx but, that didn't solve my problem.
I've just found a german website with a detailed explantion of the solution that mack gave me.
I used that one and it seems to work quite fine, expects from I somehow can't use GROUP BY. Every time I use it, it returns a Executing DB error (like before)...
I'll see if I can solve that problem...
Thx you anyway!

PS:
My code now is
SELECT
    i.id,
    i.amount,
    i.date,
    p.productname
FROM op_inventory i
LEFT JOIN products p
ON p.ItemID = i.fk_article
<!---JOIN (
    SELECT
        id id_m,
        MAX(date) maxdate
    FROM op_inventory
    GROUP BY id_m
) temp
ON i.id = temp.id_m AND i.date = temp.maxdate--->
<cfoutput>#gi_where#</cfoutput>
i.date = (
    SELECT MAX(o.date)
    FROM op_inventory o
    WHERE o.fk_article = i.fk_article
<!---GROUP BY i.id--->
And the content of #gi_where# is:
WHERE p.category = #lb_group# AND
