PDO MYSQL更新无法正常工作

我在更新用户配置文件时遇到正确的SQL查询问题。我使用(基本上)相同的查询来INSERT数据,它工作正常(没有WHERE id = clientid,并且在执行数组中没有clientid。下面的查询不会更新数据库中的任何数据。

我测试过并确保所有变量都被发布了。作为旁注,这个查询是否可以安全地从sql注入?

$conn = new PDO("mysql:host=$DB_HOST;dbname=$DB_DATABASE",$DB_USER,$DB_PASSWORD);

// Deal with the POST variables here...(excluded)

$sql = "UPDATE clients (firstname, lastname, origincountry, dob, gender, email, phone, address, postal, city, province, referred, notes)
        VALUES (:firstname, :lastname, :origincountry, :dob, :gender, :email, :phone, :address, :postal, :city, :province, :referred, :notes)
        WHERE id = :clientid" ;

$q = $conn->prepare($sql);

$q->execute(array(':firstname'=>$firstname,
                  ':lastname'=>$lastname,
                  ':origincountry'=>$origincountry,
                  ':dob'=>$dob,
                  ':gender'=>$gender,
                  ':email'=>$email,
                  ':phone'=>$phone,
                  ':address'=>$address,
                  ':postal'=>$postal,
                  ':city'=>$city,
                  ':province'=>$province,
                  ':referred'=>$referred,
                  ':notes'=>$notes,
                  ':clientid'=>$clientid));

您的SQL无效。见UPDATE。 (感谢@rambocoder指出这一点。)

使用此SQL:

UPDATE clients SET firstname = :firstname, lastname = :lastname, origincountry = :origincountry, dob = :dob, gender = :gender, email = :email, phone = :phone, address = :address, postal = :postal, city = :city, province = :province, referred = :referred, notes = :notes
WHERE id = :clientid
