There are a bunch of different reasons for the “Too Many Connections” error. Check out this FAQ page on MySQL.com: http://dev.mysql.com/doc/refman/5.5/en/too-many-connections.html Check your my.cnf file for “max_connections”. If none exist try: [mysqld] set-variable=max_connections=250 However the default is 151, so you should be okay. If you are on a shared host, it might be that other … Read more
I got this error because I forgot to start MySQL in the XAMPP controller.
The answer is that you don’t need to. The proper way to use PDO’s prepare is like this: $stmt = $pdo->prepare( “SELECT * FROM `products_keywords` WHERE `product_type` = ?”); This is the whole point of using a prepared statement. Then you bind the parameter as follows: $stmt->bindParam(1, $product_type) Proof, Schema: create table `products_keywords` ( `id` … Read more
I would check that the $db->prepare() function executed successfully. It will return false if it did not. So you could be trying to call bindParam() on a variable that equals false http://www.php.net/manual/en/pdo.prepare.php Also you should put the PDO object declaration in try/catch to be sure it was successful as well, as in the first example … Read more
Your $userData must have exactly the same placeholders bound by your statement, no more and no fewer. See PDOStatement::execute documentation, the part that says “You cannot bind more values than specified”. You need to prepare your argument to execute() to match your binds exactly. This is easy with array_intersect_key() if you arrange your arrays correctly. … Read more
There are three queries in this request and therefore you have to run them in three calls, not one: $objPdo->query(“CREATE TEMPORARY TABLE r1 SELECT CONCAT(MONTH(Heure_deb),”https://stackoverflow.com/”,DAY(Heure_deb)) as ‘Date’, Heure_deb, Operateur.Id_op , Nom_op , Prenom_op, Nom_act , TIME(Heure_deb) as heure, Commentaire, Type FROM Operateur, Pointage, Activite WHERE Operateur.Id_op = Pointage.Id_op AND Activite.Id_act = Pointage.Id_act ORDER BY date, … Read more
This seems like a bug to me: why should the charset of the connection have any effect on data for a binary column, particularly when it’s been identified as binary to PDO itself with PARAM_LOB? I do not think that this must be a bug. I can imagine that whenever the client talks with the … Read more
Try to increase error mode: <?php $hostname=”localhost”; $username=”root”; $password=”; try { $dbh = new PDO(“mysql:host=$hostname;dbname=stickercollections”,$username,$password); $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); // <== add this line echo ‘Connected to Database<br/>’; $sql = “SELECT * FROM stickercollections”; foreach ($dbh->query($sql) as $row) { echo $row[“collection_brand”] .” – “. $row[“collection_year”] .”<br/>”; } $dbh = null; } catch(PDOException $e) { echo $e->getMessage(); } … Read more
This is unfortunately a weird exception to the use of query parameters (edit: but apparently not in the most recent point-release of each MySQL branch, see below). The pattern in AGAINST() must be a constant string, not a query parameter. Unlike other constant strings in SQL queries, you cannot use a query parameter here, simply … Read more
If you turn off the default setting of PDO::ATTR_EMULATE_PREPARES, then it will work. I just found out that that setting is on by default for mysql, which means you never actually use prepared statements, php internally creates dynamic sql for you, quoting the values for you and replacing the placeholders. Ya, a major wtf. $pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, … Read more
