php - PDO_MYSQL : general error 2014

Question

我正在从普通的 mysql_* 迁移到 PDO(是的，我知道日历上是 2012 年)。
我正在编写一个简单的包装类，以便有机会做类似的事情 $f=$db->FetchAll("SELECT * FROM...")在我的网站上。这是我正在做的:

    public function Query($q, $errmessage="", $params=array()) {
    try {
    $stmt=$this->connect->prepare($q);
    if (is_array($params) && count($params)>0) {
    $stmt->execute($params);
    } else {
    $stmt->execute();
    }
    return $stmt;
    } catch(PDOException $e) {
    die($errmessage.": ".$e->GetMessage());
    }
    }

   public function Fetch($q, $arraylist=0) {
    if (!is_object($q)) { // Assuming it's a raw query
    $stmt=$this->Query($q, "Unable to process the query for fetching");
    } else $result=$q;
    $f=$stmt->Fetch();
    return $f;
}

这会引发“2014 年一般错误”异常。
任何帮助表示赞赏。
谢谢!

2014 不是年份，是错误代码。尝试 googling the error下次。

$pdo->query("INSERT INTO test (some) VALUES ('1111111111111111'), ('1111111111111'); -- I AM AN SQL COMMENT, REMOVING ME WILL SOLVE THIS PROBLEM");

Due to the ";" this is a multi-statement, executing two queries while the second is only a comment. The second "result" can be accessed using PDOStatement->nextRowset. [source]

或:

After spending hours trying to track down why we were getting this error on a new server, after the same code ran fine on other servers, we found the problem to be an old MySQL client library running on our web server, and a latest-version MySQL server running on the database server's box. [source]
