Bug #72969 [NEW]: SET ROWCOUNT returns no result

From: plebrun at wayfair dot com Operating system: CentOS7 PHP version: 7.0Git-2016-08-29 (Git) Package: PDO DBlib Bug Type: Bug Bug description:SET ROWCOUNT returns no result Description: ------------ Using SET ROWCOUNT does not return a result set (which could be expected), but it also affects the rowcounts of other queries. The same with SET NOCOUNT ON. I would expect one of the following behaviors: 1. Return empty resultset with columnCount() = 0 and rowCount() = -1; call to nextRowset() returns true 2. Does not return any resultset BUT ALSO doesn't affect other queries. See example below. Test script: --------------- <?php $db = new \PDO("dblib:host=server;dbname=database", "username", "password"); $stmt = $db->query("SET ROWCOUNT 10; INSERT INTO tbl VALUES (1, 'a'), (2, 'b');"); var_dump($stmt->rowCount()); var_dump($stmt->nextRowset()); var_dump($stmt->rowCount()); ?> Expected result: ---------------- int(-1) bool(true) int(2) Actual result: -------------- int(-1) bool(false) int(-1) -- Edit bug report at https://bugs.php.net/bug.php?id=72969&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=72969&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=72969&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=72969&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=72969&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=72969&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=72969&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=72969&r=needscript Try newer version: https://bugs.php.net/fix.php?id=72969&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=72969&r=support Expected behavior: https://bugs.php.net/fix.php?id=72969&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=72969&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=72969&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=72969&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=72969&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=72969&r=dst IIS Stability: https://bugs.php.net/fix.php?id=72969&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=72969&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=72969&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=72969&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=72969&r=mysqlcfg
