Question

下午好。运行以下INSERT INTO语句时，我一直收到以下错误。

错误：您的SQL语法出错;检查手册对应于您的MySQL服务器版本，以便使用正确的语法在第2行'，,,,,,,,）附近

我完全难过了。这可能与我在表中称为'id'的增量值有关吗？这是代码。非常感谢提前!!

<?php
$con=mysqli_connect("localhost","root","root","wexdemo");

if (mysqli_connect_errno())
{
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
}


$name = mysqli_real_escape_string($_POST['name']);
$address = mysqli_real_escape_string($_POST['address']);
$area = mysqli_real_escape_string($_POST['area']);
$postcode = mysqli_real_escape_string($_POST['postcode']);
$sector = mysqli_real_escape_string($_POST['sector']);
$subsector = mysqli_real_escape_string($_POST['subsector']);
$contact = mysqli_real_escape_string($_POST['contact']);
$position = mysqli_real_escape_string($_POST['position']);
$email = mysqli_real_escape_string($_POST['email']);
$telephone = mysqli_real_escape_string($_POST['telephone']);

$sql="INSERT INTO employers (name, address, area, postcode, sector, subsector, contact, position, email, telephone)
VALUES ($name, $address, $area, $postcode, $sector, $subsector, $contact, $position, $email, $telephone)";

if (!mysqli_query($con,$sql))
{
  die('Error: ' . mysqli_error($con));
}
echo "1 record added";

mysqli_close($con);
?>

Answer 1

插入查询值应该包含在'单引号或"双引号内。

$sql ="INSERT INTO employers (`name`, `address`, `area`, `postcode`, `sector`, `subsector`, `contact`, `position`, `email`, `telephone`)
 VALUES ('$name', '$address', '$area', '$postcode', '$sector', '$subsector',
       ..^
 '$contact', '$position', '$email', '$telephone')";

而不是

$sql="INSERT INTO employers (name, address, area, postcode, sector, subsector, contact, position, email, telephone)
VALUES ($name, $address, $area, $postcode, $sector, $subsector, $contact, $position, $email, $telephone)";

Answer 2

如果列类型为字符串，则要插入的值必须是单引号或双引号。试试这段代码：

$sql="INSERT INTO employers (name, address, area, postcode, sector, subsector, contact, position, email, telephone)
VALUES ('$name', '$address', '$area', '$postcode', '$sector', '$subsector', '$contact', '$position', '$email', '$telephone')";

您可能不希望用引号括起来的唯一值是具有数值的值 - 即$postcode和$telephone

Answer 3

变量不应包含在“或”中；即使查询已填充并且看起来正确，我也会收到相同的错误 MyError: INSERT INTO dati_modelle VALUES (1, sonia, nota 1, 14, Height, 165, Bust, 60, Waist, 65, Hips, 60, Shoe, 33, Eyes, brown) 您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，以在第 1 行的“1, 14, Height, 165, Bust, 60, Waist, 65, Hips, 60, Shoe, 33, Eyes, brown)”附近使用正确的语法

Answer 4

$sql="INSERT INTO 雇主（姓名、地址、地区、邮政编码、部门、分部门、联系人、职位、电子邮件、电话）值 ( " + "" + $name +"" + ", " + "" + $address +"" + ", " + "" + $area + "" + ", " + ""+ $sector + " " + ", " + ""+ $subsector+ "" + ", " + ""+$contact + "" + ", " + ""+$position +"" + ", " + ""+ $email + "" + ", " + "" + $电话 + "" + ")";

SQL语法错误 - 插入到语句中
