我对以下问题有疑问：

$sql = "SELECT e.*, c.name city_name, u.*, IF(l.item IS NULL, 0, 1) as iLike, DATE_FORMAT(e.date, '%h:%i') hour, DATE_FORMAT(e.date, '%d/%c/%Y') day,  DATE_FORMAT(e.date, '%c') month
FROM `events` e
LEFT OUTER JOIN `like` l ON l.item = e.uuid AND l.user = :user
            LEFT OUTER JOIN city c ON c.city = e.city
            LEFT OUTER JOIN user u ON u.user = e.user
            WHERE
             e.deleted = 0
            AND DATE(e.date) >= CURDATE()
            AND e.user = :user
            ORDER by e.date ASC
            ";
    $select = $eventsModel->getAdapter();
    $select->setFetchMode(Zend_Db::FETCH_ASSOC);
    $prepare = $select->query($sql, array('user'=>$this->user_id));

如果我将 :user 硬编码到查询中，此代码将返回结果。例子：

$sql = "SELECT e.*, c.name city_name, u.*, IF(l.item IS NULL, 0, 1) as iLike, DATE_FORMAT(e.date, '%h:%i') hour, DATE_FORMAT(e.date, '%d/%c/%Y') day,  DATE_FORMAT(e.date, '%c') month
            FROM `events` e
            LEFT OUTER JOIN `like` l ON l.item = e.uuid AND l.user = 23
            LEFT OUTER JOIN city c ON c.city = e.city
            LEFT OUTER JOIN user u ON u.user = e.user
            WHERE
             e.deleted = 0
            AND DATE(e.date) >= CURDATE()
            AND e.user = 23
            ORDER by e.date ASC
            ";
    $select = $eventsModel->getAdapter();
    $select->setFetchMode(Zend_Db::FETCH_ASSOC);
    $prepare = $select->query($sql);

这只是在我们将代码移动到新服务器时才开始发生的，新的操作系统是 Debian 6、squeze、mysql 5.5、PHP 5.3.21。

谢谢，

使用?代替:user，而$this->user_id不是array('user'=>$this->user_id)

此外，您不能在JOIN语句中绑定数据，所以l.user = e.user

$sql = "SELECT e.*, c.name city_name, u.*, IF(l.item IS NULL, 0, 1) as iLike, DATE_FORMAT(e.date, '%h:%i') hour, DATE_FORMAT(e.date, '%d/%c/%Y') day,  DATE_FORMAT(e.date, '%c') month
            FROM `events` e
            LEFT OUTER JOIN `like` l ON l.item = e.uuid AND l.user = e.user
            LEFT OUTER JOIN city c ON c.city = e.city
            LEFT OUTER JOIN user u ON u.user = e.user
            WHERE
             e.deleted = 0
            AND DATE(e.date) >= CURDATE()
            AND e.user = ?
            ORDER by e.date ASC
            ";
    $select = $eventsModel->getAdapter();
    $select->setFetchMode(Zend_Db::FETCH_ASSOC);
    $prepare = $select->query($sql, array($this->user_id));
