Beispiele

Beispiel #1 Inspecting the expanded SQL

<?php
$db = new SQLite3(':memory:');
$stmt = $db->prepare("SELECT :a, ?, :c");
$stmt->bindValue(':a', 'foo');
$answer = 42;
$stmt->bindParam(2, $answer);
var_dump($stmt->getSQL(true));
?>

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

string(24) "SELECT 'foo', '42', NULL"
