我正在使用 cookie 来跟踪网站流量，然后将其写入数据库。
我正在尝试获取我的着陆页 index.php 与所有其他页面的平均值的每日比率，以在图表中显示。
我正在为 MySQL 查询的语法而苦苦挣扎。
我想从查询中获取 2 个值:$row->day 和 $pageRatio 并显示过去 30 天的这些值。
我的数据库包含一个名为tracking 的表，其中包含以下字段:id、cid、referrerDomain、referrer、page、ip、reverseIP、userAgent、lang、date
page 字段包含网页名称，例如:index.php、other.php 等
$sql = "SELECT (
SELECT COUNT(`page`) FROM `tracking`
WHERE `page` = 'index.php'
AND DISTINCT(`date`)
GROUP BY DATE(`date`) ) AS indexCount,
(
SELECT COUNT(`page`) FROM `tracking`
WHERE `page` != 'index.php'
AND `date`
BETWEEN DATE_ADD(NOW(),INTERVAL -30 DAY)
AND NOW()
GROUP BY DATE(`date`) ) AS otherPageCount,
DATE(`date`) AS day
FROM `tracking`
WHERE `date`
BETWEEN DATE_ADD(NOW(),INTERVAL -30 DAY)
AND NOW()
GROUP BY DATE(`date`)";
$sqlprep = $conn->prepare($sql);
if($sqlprep->execute()) {
$completedAmount = 0;
while($row = $sqlprep->fetch(PDO::FETCH_OBJ)){
$pageRatio = $row->indexCount / $row->otherPageCount;
echo "['" . $row->day . "', " . $pageRatio . "],\n";
}
}
我找到的解决方案是此处接受的答案:How do I combine these 3 queries into one MySQL query?
SELECT DATE(`date`),
COUNT(`page`) AS indexCount,
SUM(`page` = 'index.php') as idx_count,
SUM(`page` <> 'index.php') as not_idx_count
FROM `tracking`
WHERE `date` BETWEEN DATE_ADD(NOW(),INTERVAL -30 DAY) AND NOW()
GROUP BY DATE(`date`)
最佳答案
也许这也行
SELECT DATE(`date`),
COUNT(`page`) AS indexCount,
SUM(`page` = 'index.php') as idx_count,
SUM(`page` <> 'index.php') as not_idx_count
TIMESTAMPDIFF(DAY,date,now()) as days
FROM `tracking` GROUP BY DATE(`date`) having days <30
