I have a result resource from a large mysql query and I need to find
the single the highest value from a certain field. What's the best way
to pull it off?
Cheers,

A simple google of "sql max" would have led you to:
SELECT MAX(expression )
FROM tables
WHERE predicates;

Thanks Shelly but I'm not great with sql and my query is already huge.
I don't think I'll be able to modify it to include the max as well as
everything else. Not to worry - I'm going to split the results into a
3d array and then try to sort it with php.
Thanks for the help

So, you go to the library, take all the books, reorganise them, search
for the one you want to read and return the rest?

No, you throw the rest away! ;)

Actually, I'm using all returned records further down my page - I just
want to pull the newest one to reference at the top.
Not to worry - the php is working out better for my design and I
almost have it sorted now anyway.

And I am almost sure, that even a second query would work out better.

Why You aren't using SQL ORDER BY clause then?
Using it properly You'll be always sure that Your newest entry is always on
the top of query result.
