Bug #61613 [Com]: No PDO error if first SQL statement of a group is valid.

Edit report at https://bugs.php.net/bug.php?id=61613&edit=1 ID: 61613 Comment by: mikhail dot v dot gavrilov at gmail dot com Reported by: trebitzki at gmx dot net Summary: No PDO error if first SQL statement of a group is valid. Status: Assigned Type: Bug Package: PDO MySQL Operating System: Mac OS X PHP Version: 5.3.10 Assigned To: mysql Block user comment: N Private report: N New Comment: This bug still not fixed in PHP 5.6.7 Linux Fedora 21 Previous Comments: ------------------------------------------------------------------------ [2014-10-13 10:26:45] pesterhazy at gmail dot com Though it is possible to run multiple statements using mysqli::multi_query, with PDO it just doesn't work. For example, if you exec() a string containing multiple INSERT statements, only the first statement will be executed. No exception is thrown (PHP 5.5.17, MySQL server 5.5.38). This is a bug. Running multiple SQL statements is useful, among other things, for creating stored procedures. ------------------------------------------------------------------------ [2014-09-29 16:34:29] trebitzki at gmx dot net The test script I included in my original bug report for this issue was only a simple example. I actually had this issue with a set of SQL UPDATE statements, so showing how fetching rows and looping through result sets obviates this is not really addressing the issue. When my first update statement runs successfully I can't call nextrowset(); the statements just run one after the other. The problem with not getting error info for any following statement that may fail still stands. And I must say that I am very surprised and disappointed that noone in the php group is willing to come to grips with this - after more than 2 1/2 years! ------------------------------------------------------------------------ [2014-09-24 16:38:09] benjamin dot morel at gmail dot com @rquadling Genius! Indeed, just tested it on a PDO configured to throw exceptions, and the PDOException is thrown as soon as nextRowSet() is called! When it's configured to *not* throw exceptions, as you guessed, the error information becomes available with PDOStatement::getErrorInfo(). So there's no bug after all, the behaviour of PHP is perfectly fine, maybe we could just mention this on the PDO error handling page in the docs? http://php.net/manual/en/pdo.error-handling.php Thanks so much. ------------------------------------------------------------------------ [2014-09-24 15:32:37] rquadling@php.net As the query contains multiple result sets, what is the response if you actually take a look at the next rowset using PDOStatement::nextRowSet() in conjunction with PDOStatement::errorInfo() / PDOStatement::errorCode()? ------------------------------------------------------------------------ [2014-07-16 13:32:14] benjamin dot morel at gmail dot com Is anyone working on this problem? As mentioned above, it can lead to dangerous bugs as there's currently no way to know if all the queries have been successfully executed or not. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
