Question

我正在搞乱一些统计工具。我的数据库看起来像这样：

ip           | campaign_id | authorized | stamp
-----------------------------------------------------
182.74.723.1 | 1           | 0          | 12349210211
82.14.127.1  | 3           | 1          | 29834043899

我想说一句话：

广告系列上有“XXX”点击，ID为“X”（“XXX”已获得授权，“XXX”未获得授权）

到目前为止我的代码：

$query = "SELECT campaign_id, COUNT(ip) FROM stats GROUP BY campaign_id"; 
$result = mysql_query($query) or die(mysql_error());

// Print out result
while($row = mysql_fetch_array($result)) {
    echo "There are <b>". $row['COUNT(ip)'] ." hits</b> on campaign with <b>ID ". $row['campaign_id'] ."</b> (HERE COMES THE PART I'M LOOKING FOR)";
    echo "<br />";
}

现在问题：我找不到计算“auth”的不同值的解决方案。如果有人能帮我解决这个问题，我会很高兴，提前谢谢！

试试这个SQL查询：

    SELECT campaign_id, 
    COUNT(ip) as tot,
    sum(authorized=0) as a0,
    sum(authorized=1) as a1,
    ....
    FROM stats GROUP BY campaign_id
