oci_bind_by_name返回截断值

当我将一行插入到一个包含1000多个条目的表中,并尝试返回行ID(无论是来自自动递增触发器/seq,还是在插入语句中手动设置值)时,我得到一个截断值:

$db = OCILogon(DATABASE_LOGIN, DATABASE_PASSWORD, DATABASE_NAME);

$mysqldate = date('Y/m/d G:i:s');
$db_vid_id = 748;
$authorID = 310;
$typeID = 2;
$timecode = 47;
$shortDescrip = "hello world";


$query = "INSERT INTO TESTTHOUSAND (ID, VIDEO_ID, AUTHOR_ID, TYPE_ID,
          DATE_CREATED, TIMECODE, SHORT_DESCRIPTION, APPROVED, IS_PUBLIC) 
          VALUES(4067, :videoID, :authorID, :typeID, TO_DATE('$mysqldate','yyyy/mm/dd HH24:MI:SS'),
          :timecode, :shortDescrip, 0, 0) 
          RETURNING ID INTO :id";
$stmt = oci_parse($db, $query);
oci_bind_by_name($stmt, ':videoID', $db_vid_id);
oci_bind_by_name($stmt, ':authorID', $authorID);
oci_bind_by_name($stmt, ':typeID', $typeID);
oci_bind_by_name($stmt, ':timecode', $timecode);
oci_bind_by_name($stmt, ':shortDescrip', $shortDescrip);
oci_bind_by_name($stmt, ':id', $theID);
oci_execute($stmt);
oci_free_statement($stmt);
oci_commit($db);
oci_close($db);

echo $theID;

此代码正确执行,值正确存储在数据库中。然而,价值 $theID

我运行的是PHP 5.2.6和Oracle 10.1
