回声mysql查询行

Question

I have the following MySQL query and I want to echo a specific row when a condition is satisfied;

global $post;
$post_author = $post->post_author;
$result = mysql_query("SELECT *, @rownum := @rownum + 1 from
    (
    SELECT (display_name) 'Author',
        IFNULL(ROUND(SUM(balance.meta_value),2),2) 'Balance'
    FROM posts p
    JOIN users u 
        ON p.post_author = u.ID
    JOIN postmeta odd ON p.ID = odd.post_id AND odd.meta_key = 'odd' AND odd.meta_value >= 1.5
    LEFT JOIN postmeta balance 
        ON p.ID = balance.post_id AND balance.meta_key = 'balance'
    WHERE p.post_status = 'publish'
    GROUP BY u.ID
    ORDER BY Balanco DESC
    )x, (SELECT @rownum := 0) r");
$row = mysql_fetch_array($result);

I want to echo row 3 when the Author equals $post_author, can someone help me with this. Thanks.

<?php echo "{$row[3]}";?> where Author=$post_author

I believe a simple if would make you happy:

if ($row[0] == $post_author)
    echo $row[3];
