Question

我需要从每列收集计数，每行有多个结果。问题是列是复制第一列的值。

  $sql="SELECT MODEL, 
     sum(CLICK) AS LOCCLICK, sum(VIEW) AS LOCVIEW, sum(EMAIL) AS LOCEMAIL, sum(SHARE) AS LOCSHARE
      FROM     STAT
      WHERE    ID = ".$id."
      GROUP BY MODEL";
       $result = $mysqli->query($sql);

        if ($result->num_rows > 0) {
            // output data of each row
            while($row = $result->fetch_assoc()) {
                $clickcoun = $row['LOCCLICK'];
                $viewcoun = $row['LOCVIEW'];
                $emailcoun = $row['LOCEMAIL'];
                $sharecoun = $row['LOCSHARE'];
                $model = $row['MODEL'];
                echo "\n";
                // Log the stats into the daily updates.
                 $sqlx = 'INSERT INTO DAILY (ID, QDATE, VIEWS, CLICKS, EMAILS, SHARES, MODEL) 
                VALUES ('.$id.', NOW(), '.$viewcoun.', '.$clickcoun.', '.$emailcoun.', '.$sharecoun.', "'.$model.'" )';
                  $mysqli->query($sqlx);
                  } 
                 } else {
                      echo "0 results"; die();
                 }

我要找的结果如下：

Ford：views = 302，emails = 21，shares = 10

Dodge：views = 567，emails = 41，shares = 13

雪佛兰：views = 324，电子邮件= 23，shares = 9

我想将这些输入到每日统计数据细分中，以便我可以查询它们将它们放入图表并显示其每日覆盖面。在本月底，我打算以同样的方式再次打破这些月度概述。

您不需要循环来执行此操作。只需使用insert . . . select：

INSERT INTO DAILY (ID, MODEL, CLICKS, VIEWS, EMAIL, SHARES, QDATE) 
    SELECT $id, MODEL, sum(CLICK) AS LOCCLICK, sum(VIEW) AS LOCVIEW,
           sum(EMAIL) AS LOCEMAIL, sum(SHARE) AS LOCSHARE, now()
    FROM STAT
    WHERE ID = ".$id."
    GROUP BY MODEL;

在按功能分组的多列上的sum（）
