SQLite3Stmt::getSQL — Get the SQL of the statement
Retrieves the SQL of the prepared statement. If expand
is false, the unmodified SQL is retrieved. If expand
is true, all query parameters are replaced with their bound values, or with
an SQL NULL, if not already bound.
expand
Whether to retrieve the expanded SQL. Passing true is only supported as
of libsqlite 3.14.
If expand is true, but the libsqlite version is less
than 3.14, an error of level E_WARNING or an Exception
is issued, according to SQLite3::enableExceptions().
Ejemplo #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));
?>El resultado del ejemplo sería algo similar a:
string(24) "SELECT 'foo', '42', NULL"
