Selecting the Strongest Character?

[kaotic]

I've got somewhat of an RPG system going on, and I want to select and display the strongest member from a table.

I think it should look something like...

$strongguy = $DB_site->query("SELECT * FROM table ORDER BY column DESC LIMIT 1");

After which, I would put {$strongguy['name'} in the template, but I seem to get some kind of resource error each time. Is something wrong with my query?

Yes there is something wrong...look closely at your query...how does your query know which person is the strongest?

If you can't figure out what you need I will post it but just trying to help you learn...

Eh, I'm not sure how to select the highest value of a field. I'm guessing I need something about "WHERE", but I wouldn't know. Any knowledge I have of this is based on other hacks I've installed, and I don't see a similiar query anywhere.

Care to elaborate for me?

I couldn't find the solution there - think you could just hook me up with the query?

Try this:

PHP Code:

$strongguy = $DB_site->query("
                        SELECT name, str
                        FROM inferno_user
                        WHERE str = MAX(str)");

I tried that query earlier, it says something about an invalid group function use.

use this:

PHP Code:

$array = $DB_site->query_first("SELECT * FROM table ORDER BY powerfield DESC LIMIT 1");

yes, Brad is correct, you have to use query_first, as this would return an array, query() just returns a mysql result pointer
