tutorial - Obtener la última consulta ejecutada en PHP PDO



php pdo execute (2)

La mayoría de las personas crea una clase contenedora alrededor del objeto PDO para registrar las consultas a medida que se envían a la base de datos. Casi nadie usa un objeto directo de PDO ya que puede agregar métodos adicionales de ayuda envolviendo o extendiendo PDO .

/** * Run a SQL query and return the statement object * * @param string $sql query to run * @param array $params the prepared query params * @return PDOStatement */ public function query($sql, array $params = NULL) { $statement = $this->pdo->prepare($sql); $statement->execute($params); // Save query results by database type self::$queries[] = $sql; return $statement; }

Me gustaría saber qué consulta se ejecuta con PHP PDO. Yo tengo:

<?php try { $DBH = new PDO("mysql:host=localhost;dbname=mytable", ''myuser'', ''mypass''); } catch(PDOException $e) { echo $e->getMessage(); } $DBH->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING ); $DBH->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION ); $STH = $DBH->("INSERT INTO mytable (column1, column2, column3 /* etc...*/) value (:column1, :column2, :column3 /* etc...*/)"); $STH->bindParam('':column1'', $column1); $STH->bindParam('':column2'', $column2); $STH->bindParam('':column3'', $column3); /* etc...*/ $STH->execute(); // what is my query?

Me gustaría obtener algo como:

INSERT INTO mytable (column1, column2, column3) value (''my first column'', 32, ''some text'')

¿Es posible? Gracias


<?php class MyPDOStatement extends PDOStatement { protected $_debugValues = null; protected function __construct() { // need this empty construct()! } public function execute($values=array()) { $this->_debugValues = $values; try { $t = parent::execute($values); // maybe do some logging here? } catch (PDOException $e) { // maybe do some logging here? throw $e; } return $t; } public function _debugQuery($replaced=true) { $q = $this->queryString; if (!$replaced) { return $q; } return preg_replace_callback(''/:([0-9a-z_]+)/i'', array($this, ''_debugReplace''), $q); } protected function _debugReplace($m) { $v = $this->_debugValues[$m[1]]; if ($v === null) { return "NULL"; } if (!is_numeric($v)) { $v = str_replace("''", "''''", $v); } return "''". $v ."''"; } } // have a look at http://www.php.net/manual/en/pdo.constants.php $options = array( PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION, PDO::ATTR_STATEMENT_CLASS => array(''MyPDOStatement'', array()), ); // create PDO with custom PDOStatement class $pdo = new PDO($dsn, $username, $password, $options); // prepare a query $query = $pdo->prepare("INSERT INTO mytable (column1, column2, column3) VALUES (:col1, :col2, :col3)"); // execute the prepared statement $query->execute(array( ''col1'' => "hello world", ''col2'' => 47.11, ''col3'' => null, )); // output the query and the query with values inserted var_dump( $query->queryString, $query->_debugQuery() );
