Question

今天我在尝试进行一些查询时得到了一个不寻常的响应，这里是错误输出。

[17-Feb-2014 12:37:24 America/Denver] PHP Warning:  PDOStatement::execute():
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 'key = 'AH3D'' at line 1 in file on line 28

以下是我使用的代码，这就是我一直以来的做法。

public function get($key = null) {
    $get = $this->conn->prepare("SELECT url FROM urls WHERE key = :get");
    $get->execute(array(':get' => $key));
    return $get->fetch();
}

我如何调用该函数。

echo $tiny->get($_GET['key']);

密钥是一个mysql保留关键字，您需要在列名称key

周围使用反向标记

$get = $this->conn->prepare("SELECT url FROM urls WHERE `key` = :get");
