Bug #62820 [Com]: mysqlnd API incompatability breaks PDOStatement->nextRowset()

Edit report at https://bugs.php.net/bug.php?id=62820&edit=1 ID: 62820 Comment by: nikic@php.net Reported by: nikic@php.net Summary: mysqlnd API incompatability breaks PDOStatement->nextRowset() Status: Assigned Type: Bug Package: PDO related PHP Version: master-Git-2012-08-14 (Git) Assigned To: mysql Block user comment: N Private report: N New Comment: Just looked at the code again, what I said above is wrong. The code checks mysql_more_results() before (http://lxr.php.net/xref/PHP_TRUNK/ext/pdo_mysql/mysql_statement.c#414), so it should not be related to the return value of mysql_next_result(). Something else is wrong.

This causes several test failures, which all have a diff looking similar to this: 008+ 009+ Warning: PDOStatement::fetchAll(): SQLSTATE[HY000]: General error in %s/bug_41997.php on line 11 010+ array(0) { 011+ } This can be traced down to mysql_next_result() returning 0 instead of -1 in http://lxr.php.net/xref/PHP_TRUNK/ext/pdo_mysql/mysql_statement.c#415. The reason is that (when using mysqlnd) mysql_next_result is aliased to mysqlnd_next_result, but both have different APIs: The mysqlnd_ version only returns PASS = 0 or FAIL = 1, whereas the mysql_ version returns -1 if the call worked, but there were no more resultsets. This is documented at http://dev.mysql.com/doc/refman/5.0/en/mysql-next-result.html in the "Return Values" section. The default mysqlnd next_result implementation is here: http://lxr.php.net/xref/PHP_TRUNK/ext/mysqlnd/mysqlnd.c#2100. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62820&edit=1
