Description:
------------
When binding out variables, you have to specify the data type and length
manually with PDO_OCI.
If not you receive an oracle error:
ORA-03131: an invalid buffer was provided for the next piece
This bug exists in both PHP 5.2.12 and 5.3.1
Reproduce code:
---------------
the following simple code easily re-produces the bug:
try {
$dbConn = new PDO('oci:dbname=.....);
$dbConn->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);
$sql = $dbConn->prepare("
BEGIN
SELECT username
INTO :chkId
FROM USERS
WHERE username = 'fred';
END;
");
$sql->bindParam('chkId', $chkId);
$sql->execute();
var_dump($chkId);
} catch (Exception $e) {
var_dump($e);
}
obviously I've censored our connection info.
as the other user mentioned in bug #39820 if I alter the bindParam to:
$sql->bindParam('chkId', $chkId, PDO::PARAM_STR, 10);
it works. however even missing off the variable length causes a error
Expected result:
----------------
string ('fred');
Actual result:
--------------
object(PDOException)#3 (8) {
