Question

我是编程方面的超级新秀。我不确定为什么会出现此错误。我搜索了同样的问题，但他们没有工作。这是完整的错误：

错误：SQLSTATE [42000]：语法错误或访问冲突：1064 SQL语法中有错误;检查与您的MariaDB服务器版本对应的手册，以便在第3行的'WHERE id ='3''附近使用正确的语法

<?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,

    $conn = null;

else {
  echo "Error: You have execute a wrong PHP. Please contact the web administrator.";

Answer 1

您在末尾添加了额外的逗号

endtime = :endtime, WHERE id = :record_id

在：endtime

之后删除逗号

endtime = :endtime  WHERE id = :record_id

Answer 2

之后 $ stmt WHERE 之前删除逗号 字符串：

$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");
