Question

在phpMyAdmin工作台中运行查询时，结果与预期一致，total具有值。但是，在PHP中运行相同的代码时，PDO total始终为0.这是SQLFiddle。

PHP代码：

        $stmt = "
SELECT COUNT(*) as `total`
FROM   `provider_availability`
WHERE  `provider_availability`.`practitioner_id` = :practitioner_id
       AND `provider_availability`.`weekday` = :weekday
       AND `provider_availability`.`ID` != :edit_id
       AND `deleted` = 0
       AND ( :start_time BETWEEN `provider_availability`.`starting_time` AND `provider_availability`.`ending_time`
        OR   :end_time BETWEEN `provider_availability`.`starting_time` AND `provider_availability`.`ending_time` )";


        $query = $this->connection->prepare($stmt);
        $query->bindValue(':practitioner_id', $_SESSION['user']['ID'], PDO::PARAM_INT);
        $query->bindValue(':weekday', $weekday, PDO::PARAM_INT);
        $query->bindValue(':edit_id', $edit_id, PDO::PARAM_INT);
        $query->bindValue(':start_time', $start_time, PDO::PARAM_STR);
        $query->bindValue(':end_time', $end_time, PDO::PARAM_STR);

        if ($query->execute() == true) {
            $row = $query->fetch(PDO::FETCH_ASSOC);

            return $row['total'];
        } else {
            die(json_encode([
                "success" => false,
                "reason" => $query->errorInfo()
            ]));
        }

这是不可能的。

PDO将从不为您提供不同的结果，因为发送的查询和连接的数据库是相同的。

PHP PDO获得与工作台不同的MySQL结果
