PDO Multi-query “SQLSTATE[HY000]: General error”

Question

I\'m still learning PDO so I might of missed something but basically I\'m trying to insert a row into a table and then select the generated id.

I\'m not sure if it l

Answer 1

I'm pretty sure the mysql driver for PDO (maybe mysql itself?) does not support multi-query prepared statements.

Instead of SELECT LAST_INSERT_ID() in your query, use Conexion::$cn->lastInsertId() after your $query->execute()

Answer 2

I think this is correct:

function ExecuteQuery($sql, $params = array())
{
    if(Conexion::$cn== null)
        Conexion::Connect();
    $paramString="";

    foreach($params as $k=>$v)
    {
        $param = " :".$k." ,";
        $paramString .= $param;
    }
    $sql.=substr($paramString,0,-2);
    $query = Conexion::$cn->prepare($sql);
    foreach($params as $key => $value)
    {
        echo "entro";
        $query->bindParam(":".$key, $value);
    }

    $query->execute();
    $x = $query->fetchAll(\PDO::FETCH_ASSOC);
    var_dump($x);
    return $x;
}

public function Connect()
{
    try {
        $dns='dblib:host='.Conexion::$server.";dbname=".Conexion::$db.";";
        Conexion::$cn = new \PDO($dns, Conexion::$user, Conexion::$passw);
        Conexion::$cn->setAttribute( \PDO::ATTR_ERRMODE, \PDO::ERRMODE_EXCEPTION );
    }
    catch(PDOException $e) 
    {
        echo $e->getMessage();
    }
}
