#45763 [Asn->Csd]: mysqli::multi_query does not work with mysqlnd

ID: 45763 Updated by: johannes@php.net Reported By: michael dot kofler at gmx dot com -Status: Assigned +Status: Closed Bug Type: MySQLi related Operating System: linux PHP Version: 5.3.0alpha1 Assigned To: johannes New Comment: This bug has been fixed in CVS. Snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. Thank you for the report, and for helping us make PHP better. The MySQLi case is fixed, the PDO case works for me with emulated prepared statements. Multi Query isn't supported by MySQL when using native prepared statements.

More like - first execution fails, second and all after work fine. It does not matter if you use the procedural or OO interface. The test does not catch it because it first does parameter tests (e.g. mysqli_multi_query($link, "") - expected to fail) before it runs a query. And "runs a query" is the second function call. But anyway Johannes, if its not in the inner workings of mysqlnd itself, try to shield Andrey from PHP works. Ulf ------------------------------------------------------------------------ [2008-08-09 07:34:53] uw@php.net Works with the procedural interface, use procedural style until fix has been committed. Re-assigning to Johannes. Andrey is busy with non-PHP work at the moment. Johannes please have a look ------------------------------------------------------------------------ [2008-08-09 00:21:13] johannes@php.net Assigning to primary maintainer ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
