PHP / SQL：成功更新数据行但出现PHP致命错误

【中文标题】PHP / SQL：成功更新数据行但出现PHP致命错误【英文标题】：PHP / SQL: Successful update a data row but got PHP Fatal Error 【发布时间】：2020-03-12 02:16:45 【问题描述】：我的代码中有一个非常奇怪的问题。简而言之，我创建了一个系统，它有一个名为dashboard_engineer.php 的仪表板。此仪表板将仅显示 SQL 数据库的前 30 个数据行。此仪表板还包含 3 个过滤输入，它们是：
团队
日期
日期
用户可以使用此过滤器来查找他们的确切数据行。用户只需填写输入并按下按钮搜索，这会将用户重定向到dashboard_engineer2.php。
在此仪表板中，将显示所有过滤后的数据行。每个数据行都包含一个 View 和一个 Remove 按钮。删除按钮用于通过更新删除数据行的详细信息。
我的问题是，在过滤后的数据中，当我点击删除按钮时，数据在 SQL 数据库中更新，但它会显示此错误：
PHP 致命错误：未捕获的 PDOException：SQLSTATE[42000]：[Microsoft][ODBC Driver 17 for SQL Server][SQL Server]'10' 附近的语法不正确。在 C:\inetpub\wwwroot\tgotworker_testing\pages\dashboard\engineer\dashboard_engineer2.php:157
当我从未过滤的数据行（dashboard_engineer.php）中单击删除按钮时，数据被删除，之后没有错误显示。
任何有关如何解决此问题的建议将不胜感激。以下是我的代码：
dashboard_engineer.php

【问题讨论】：
使用参数化查询而不是连接变量，我敢打赌它会解决它。 问题可能是您将数字放在引号中。 mysql 允许这样做，我怀疑 SQL-Server 不允许。 @Barmar 你能帮我修一下吗？ 【参考方案1】：使用参数化查询而不是连接变量。
$query = "
SELECT *
FROM ot_report
LEFT JOIN ot_users ON ot_report.badgeid = ot_users.badgeid
WHERE ot_report.status = 'yes'
AND ot_users.team_id = :team
AND report_date BETWEEN :from AND :to
ORDER BY ot_report.report_id DESC";
$sql = $conn->prepare($query, array(PDO::ATTR_CURSOR => PDO::CURSOR_SCROLL));
$sql->bindParam(':team', $team, PDO::PARAM_INT);
$sql->bindParam(':from', $from, PDO::PARAM_INT);
$sql->bindParam(':to', $to, PDO::PARAM_INT);
$sql -> execute();
【讨论】：
感谢您的回答，但我收到此错误。将 nvarchar 值“10”转换为数据类型 int 时转换失败。也在同一行 更新了答案以显示如何将它们强制为特定的数据类型。 什么是10，是团队ID吗？【参考方案2】：
我在remove2.php 找到了答案，问题。下面是代码：
<?php
include('../../../config/configPDO.php');
$report_id = $_POST['report_id'];
$from = $_POST['from'];
$to = $_POST['to'];
$team = $_POST['team'];
$sql = "UPDATE ot_report SET status = 'no' WHERE report_id=:report_id";
$query = $conn->prepare($sql);
$query->execute(array(':report_id' => $report_id));
header("Location: dashboard_engineer2.php?from=".$from."&to=".$to."&team=".$team."");
?>
