PHP，MySQL错误：列数与第1行的值数不匹配

我收到此错误：

Column count doesn't match value count at row 1

从以下代码：

$name = $_GET['name']; $description = $_GET['description']; $shortDescription = $_GET['shortDescription']; $ingredients = $_GET['ingredients']; $method = $_GET['method']; //$image = $_GET['image']; $username = $_GET['username']; $length = $_GET['length']; $dateAdded = uk_date(); $conn = mysql_connect('localhost', 'dbname', 'pass'); mysql_select_db('dbname'); $query = sprintf("INSERT INTO dbname (id, Name, Description, shortDescription, Ingredients, Method, Length, dateAdded, Username) VALUES ('', '%s', '%s', '%s', '%s', '%s', '%s', '%s')", mysql_real_escape_string($name), mysql_real_escape_string($description), mysql_real_escape_string($shortDescription), mysql_real_escape_string($ingredients), //mysql_real_escape_string($image), mysql_real_escape_string($length), mysql_real_escape_string($dateAdded), mysql_real_escape_string($username));

$result = mysql_query($query) or die(mysql_error());

错误是什么意思？
