MYSQL SELECT与COUNT，FROM，WHERE，GROUP BY跳过第一行返回

I have a query as follows, I get the response and for some reason the while loop never catches the first group of status returned. If MySQL returned status I,S,N it will only process the S and N. If it returns S,N it will only process N.

$sql = "SELECT    COUNT(*) as cnt, status
        FROM      itemInterest
        GROUP BY  status
        ORDER BY  STATUS";

echo $sql;
$rs = mysql_query($sql);
while($row = mysql_fetch_array($rs))
{
    echo $row['status'];
    if($row['status'] == "N") {
        $noResponse = $row['cnt'];
    }
    if($row['status'] == "S") {     
        $saved = $row['cnt'];
    }
    if($row['status'] == "I") {
        $interested = $row['cnt'];
    }
    if($row['status'] == "X") {    
        $noThanks = $row['cnt'];
    }
}

You have 2 sets of brackets $rs = mysql_query(($sql)); remove a set $rs = mysql_query($sql);

Add mysql_query() or die(mysql_error()) to mysql_query() also to check for errors.

You are using a deprecated MySQL library which will be removed from future PHP releases.

Consider using mysqli with prepared statements, or PDO with prepared statements.
