我正在使用 PDO,并且在使用以下代码时出现错误:
$stmt = $pdo->prepare("SELECT username FROM users WHERE
WHERE INSTR(`games`, '{$gameid}') > 0
");
$gameid = $gamedata['id'];
$stmt->execute(array(
':gameid'=>$gameid
));
$players = $stmt->fetch(PDO::FETCH_ASSOC);
通过查看过去的答案,这应该可以工作,但是我遇到了以下错误:
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax
error or access violation: 1064 You have an error in your SQL syntax; check the manual
that corresponds to your MySQL server version for the right syntax to use near 'WHERE
INSTR(`games`, 'crysis') > 0' at line 2' in C:\xampp\htdocs\gs\gamepage.php:19 Stack
trace: #0 C:\xampp\htdocs\gs\gamepage.php(19): PDOStatement->execute(Array) #1 {main}
thrown in C:\xampp\htdocs\gs\gamepage.php on line 19
它也似乎将“游戏”作为文字而不是列
我究竟做错了什么?
