我正在尝试对 pdo 使用简单的 UPDATE 查询，但在查看问题 5 小时后，我只是丢失了它。也许你们中的一些人知道我做错了什么。
我总是收到此错误：“10-24 17:59:08.829: D/test(1794): Warning : PDOStatement::execute() [pdostatement.execute]: SQLSTATE[HY093]: Invalid parameter” number: parameter未定义
$name = $_POST['name'];
$buyin = $_POST['buyin'];
$result = $_POST['result'];
$startDate = $_POST['startDate'];
$endDate = $_POST['endDate'];
$location = $_POST['location'];
$isTournament = $_POST['isTournament'];
$participants = $_POST['participants'];
$endPosition = $_POST['endposition'];
$comment = $_POST['comment'];
$blinds = $_POST['blinds'];
$pause = $_POST['pause'];
$game_id = $_POST['game_id'];
$user_id = $_POST['user_id'];
try {
$dbconn = 'mysql:host=' . DBHOST . ';dbname=' . DBDATA;
$db = new PDO($dbconn, DBUSER, DBPASS);
} catch (PDOException $e) {
echo 'Connection failed: ' . $e->getMessage();
}
$sql = 'UPDATE game SET name = :name AND buyin = :buyin AND result = :result AND startDate = :startDate AND endDate = :endDate AND
location = :location AND isTournament = :isTournament AND participants = :participants AND endposition = :endposition AND comment = :comment AND blinds = :blinds AND pause = :pause
WHERE game_id = :game_id AND user_id = :$user_id';
$statement = $db->prepare($sql);
$boolean = $statement->execute(array(':name' => $name, ':buyin' => $buyin, ':result' => $result,':startDate' => $startDate, ':endDate'
=>$endDate, ':location'=> $location, ':participants'=> $participants, ':endposition' => $endPosition, ':comment' => $comment, ':blinds' => $blinds, ':pause' => $pause, ':game_id' => $game_id,':user_id' => $user_id));
我的 mysql 表如下所示：
Naam Type
1 game_id int(11)
2 user_id int(11)
3 name varchar(45)
4 buyin double
5 result double
6 startDate bigint(20)
7 endDate bigint(20)
8 location
9 isTournament
10 participants
11 endposition
12 comment text
13 blinds text
14 pause bigint(20)
