Description:
------------
When using any of the various methods of binding parameter values, a query produces no results. When including the parameter value directly in the query string, the query does produce results.

Reproduce code:
---------------
$db = new PDO('oci://localhost/XE', '------', '-----');

$id = 'Wilson';

$sql = 'SELECT C.* FROM BreadCrumbLinks B, BreadCrumbLinks C WHERE B.Lft BETWEEN C.Lft AND C.Rgt AND B.SiteAreaName = :id ORDER BY C.Lft';
$stmt = $db->prepare($sql);
$stmt->bindValue(':id', $id, PDO::PARAM_STR); // Also tried without typecasting and without a colon in the parameter name
$stmt->execute(); // also tried with an associative array of parameters and an enumerated array using ? in place of :id in the query
print_r($stmt->fetchAll());

$sql = 'SELECT C.* FROM BreadCrumbLinks B, BreadCrumbLinks C WHERE B.Lft BETWEEN C.Lft AND C.Rgt AND B.SiteAreaName = \'' . $id . '\' ORDER BY C.Lft';
$stmt = $db->prepare($sql);
$stmt->execute();
print_r($stmt->fetchAll());

Expected result:
----------------
Array
(
    [0] => Array
        (
            [SITEAREANAME] => Home
            [0] => Home
            [SITEAREAURL] => Default.aspx
            [1] => Default.aspx
            [LFT] => 1
            [2] => 1
            [RGT] => 24
            [3] => 24
        )
)
Array

    [0] => Array
        (
            [SITEAREANAME] => Home
            [0] => Home
            [SITEAREAURL] => Default.aspx
            [1] => Default.aspx
            [LFT] => 1
            [2] => 1
            [RGT] => 24
            [3] => 24
        )
)

Actual result:
--------------
