In the MySQL docs, there is a note about using mysql_affected_rows after a transaction commit: http://php.net/manual/en/function.mysql-affected-rows.php Note: Transactions If you are using transactions, you need to call mysql_affected_rows() after your INSERT, UPDATE, or DELETE query, not after the COMMIT. However, there is no such note on the PDOStatement::rowCount doc: http://www.php.net/manual/en/pdostatement.rowcount.php Does this mean the commit will not affect the affected rows count after INSERT, UPDATE or DELETE queries when using the PDO object? A PDOStatement is returned for each

The PDOStatement::bindValue() method offers a way to specify the type of the variable bound: PDOStatement::bindValue ( $parameter , $value [, $data_type = PDO::PARAM_STR ] ) I'm wondering, what's the purpose of specifying the data type, whereas when leaved as default ( PARAM_STR ) eventually the database will anyway cast the value to the proper type before using it? For example, if you have these queries over an INTEGER field: INSERT INTO table (integerField) VALUES (?) ; SELECT * FROM table WHERE integerField = ? ; And you bind an integer in PHP, PDO will by default bind it as a string, which

<?php require 'database.php'; $id = 0; if ( !empty($_GET['user_id'])) { $id = $_REQUEST['user_id']; } if ( !empty($_POST)) { // keep track post values $id = $_POST['user_id']; // delete data $pdo = Database::connect(); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $sql = "DELETE FROM admin WHERE id = ?"; ===> Wrong on here.. //LINE18 $q = $pdo->prepare($sql); $q->execute(array($id)); Database::disconnect(); header("Location: index.php"); } ?> somebody can help me? why i got Uncaught exception 'PDOException' with message 'SQLSTATE[42S22] sorry my english is bad, thanks The

Is there a list describing all of the data_type parameters you can use in PDOStatement::bindParam() ? If none, what do you commonly use, and for what type of field ? According to PHP manual: data_type Explicit data type for the parameter using the PDO::PARAM_* constants. I know about the PDO::PARAM_INT and PDO::PARAM_STR . I've heard of PDO::PARAM_LOB but I wasn't sure how and when to use that, though. (for date ?) From the documentation here : PDO::PARAM_BOOL (integer) Represents a boolean data type. PDO::PARAM_NULL (integer) Represents the SQL NULL data type. PDO::PARAM_INT (integer)

I am using PDOStatement to query the database. Whenever I get a returned row, I want it to be fetched into an array, with the $row[0] as the key, and the subsequent elements in the row as the values. I can, of course, write a combination of foreach loops and if conditionals to do the job, such as the below: private static function GetMySQLResult($dbname, $sqlString) { $dbh = self::ConstructPDOObject($dbname); $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $result=array(); foreach ($dbh->query($sqlString) as $row) { $result[$row[0]][]=$row[1]; // the simplest case for 2 columns,
