Bug #75201 [NEW]: 0-column rowsets not identified

From: fandrieu at gmail dot com Operating system: Linux PHP version: Irrelevant Package: PDO DBlib Bug Type: Bug Bug description:0-column rowsets not identified Description: ------------ This is a follow up to the bug #69592 about skipping 0-column rowsets I've been using the suggested "if ($statement->columnCount())" workaround to avoid this problem, but it doesn't work after a non empty rowset: columnCount is not set correctly and reports the column count of the previous rowset. Test script: --------------- $pdo = new PDO("dblib:host=<host>;dbname=<dbname>", "username", "password"); $stmt = $pdo->query(" SET NOCOUNT ON SELECT 1 SET NOCOUNT ON SELECT 1 "); do { echo "columns: " . $stmt->columnCount() . "\n"; print_r($stmt->fetchAll(PDO::FETCH_ASSOC)); } while ($stmt->nextRowset()); Expected result: ---------------- [with bug #69592] columns: 0 Array ( ) columns: 1 Array ( [0] => Array ( [computed] => 1 ) ) columns: 0 Array ( ) columns: 1 Array ( [0] => Array ( [computed] => 1 ) ) Actual result: -------------- columns: 0 Array ( ) columns: 1 Array ( [0] => Array ( [computed] => 1 ) ) columns: 1 Array ( ) columns: 1 Array ( [0] => Array ( [computed] => 1 ) ) -- Edit bug report at https://bugs.php.net/bug.php?id=75201&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=75201&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=75201&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=75201&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=75201&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=75201&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=75201&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=75201&r=needscript Try newer version: https://bugs.php.net/fix.php?id=75201&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=75201&r=support Expected behavior: https://bugs.php.net/fix.php?id=75201&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=75201&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=75201&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=75201&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=75201&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=75201&r=dst IIS Stability: https://bugs.php.net/fix.php?id=75201&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=75201&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=75201&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=75201&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=75201&r=mysqlcfg
