Bug #66950 [NEW]: PDO::FETCH_OBJ fails with "Cannot access empty property"

From: mike at oobak dot org Operating system: Red Hat Enterprise Linux 6.3 PHP version: 5.5.10 Package: PDO ODBC Bug Type: Bug Bug description:PDO::FETCH_OBJ fails with "Cannot access empty property" Description: ------------ PHP 5.5.10 unixODBC 2.3.2 tdodbc (Teradata ODBC driver) 14.10 Attempts to use PDO::FETCH_OBJ and PDO::FETCH_CLASS fail with the error "Cannot access empty property." Switching to PDO::FETCH_LAZY shows a blank field name (see below). Other methods such as PDO::FETCH_NAMED and PDO::FETCH_ASSOC work fine. Plain vanilla odbc_fetch_obj() (without PDO) works fine. PDO::FETCH_OBJ works fine with a different ODBC driver. pdo_odbc / Teradata / PDO::FETCH_OBJ => fails pdo_odbc / Teradata / PDO::FETCH_CLASS => fails pdo_odbc / Teradata / PDO::FETCH_NAMED => succeeds pdo_odbc / Oracle / PDO::FETCH_OBJ => succeeds odbc / Teradata / odbc_fetch_obj() => succeeds Test script: --------------- $dbh = new PDO("odbc:FOO"); $sth = $dbh->query(" SELECT rolename FROM dbc.allrolerights WHERE databasename = 'BAR' "); $result = $sth->fetch(PDO::FETCH_OBJ); Expected result: ---------------- object(stdClass)#1 (1) { ["RoleName"]=> string(30) "FNAR " } Actual result: -------------- PDO::FETCH_OBJ or PDO::FETCH_CLASS (with stdClass or user class): PHP Fatal error: Cannot access empty property PDO::FETCH_LAZY: object(PDORow)#3 (2) { ["queryString"]=> string(95) " SELECT rolename FROM dbc.allrolerights WHERE databasename = 'BAR' " [""]=> string(30) "FNAR " } PDO::FETCH_NAMED: array(1) { ["RoleName"]=> string(30) "FNAR " } My stack thread: http://stackoverflow.com/questions/22614222/pdo-returning-empty-property-name -- Edit bug report at https://bugs.php.net/bug.php?id=66950&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=66950&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=66950&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=66950&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=66950&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=66950&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=66950&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=66950&r=needscript Try newer version: https://bugs.php.net/fix.php?id=66950&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=66950&r=support Expected behavior: https://bugs.php.net/fix.php?id=66950&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=66950&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=66950&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=66950&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=66950&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=66950&r=dst IIS Stability: https://bugs.php.net/fix.php?id=66950&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=66950&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=66950&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=66950&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=66950&r=mysqlcfg
