Example within a PHP context:

/* using sqlite 3 database SQLLDB is a define() path to the database location elsewhere */

if (!($db = new PDO('sqlite:' . SQLLDB))) {

	$error = $db->errorInfo();



/* the direction in which to order the query */

$direction = "ASC";

$query = $db->prepare('SELECT * FROM table_name ORDER BY value :dir');

$query->bindParam(':dir', $direction, PDO::PARAM_STR, 4);


Here, a error stating that the prepare() failed occurs due to acting on a non-object. Would it be possible to maybe allow place holders for actual parts of the SQL query, rather than just values?


Reproduce code:
as above.

Expected result:
for the data to be retrieved from the database and ordered either ASC or DESC according to the value of $direction

Actual result:
PDO/SQLite error. As above.

Sorry, but your problem does not imply a bug in PHP itself.  For a

of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.
