php - SQLSTATE[42000] : Syntax error or access violation: 1064 phpmyadmin

Question

我是编程方面的 super 菜鸟。我不确定为什么会出现这个错误。我搜索过同样的问题，但它们不起作用。这是完整的错误:

Error: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'WHERE id = '3'' at line 3

<?php

if (isset($_POST['LMedit_form'])) {

  include "db.php";

  try {
    $conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    $stmt = $conn->prepare("UPDATE lmreservation SET name = :name, studentstaffid = :studentstaffid, faculty = :faculty, contactno = :contactno, 
    email = :email, program = :program, participant = :participant, attandance = :attandance, module = :module, date = :date, starttime = :starttime, endtime = :endtime,
    WHERE id = :record_id");

    $stmt->bindParam(':name', $name, PDO::PARAM_STR);
    $stmt->bindParam(':studentstaffid', $studentstaffid, PDO::PARAM_STR);

    $stmt->execute();

    header("Location:LMlist_reservation.php");
    }

    catch(PDOException $e)
    {
        echo "Error: " . $e->getMessage();
    }

    $conn = null;
  }
else {
  echo "Error: You have execute a wrong PHP. Please contact the web administrator.";
  die();
}

?>

您在末尾添加了额外的逗号

endtime = :endtime, WHERE id = :record_id

删除:endtime后面的逗号

endtime = :endtime  WHERE id = :record_id
