 New Comment:

I'll chime in as another voice of reason: this should be 
fixed before 5.0.1. At the moment, prepared statements 
are basically useless, as half the time they give this 
error and fail to return any data. I'm on MacOS X and 
Apache 2, with the same problem.

Hi,

I have got the same problem. I am using PHP5 release with
MySQL4.1.3-beta. 

The code is simple:

$mysqli = new mysqli(); // connected successfully
$stmt = $mysqli->prepare("SOME VALID QUERY");
$stmt->execute(); // No problem here

$mysqli2 = $mysqli;
$mysqli2->query("THE SAME QUERY"); // Still OK
$stmt2 = $mysqli2->prepare("THE SAME QUERY");
$stmt2->execute();

The last line failed and returning "Warning: Statement isn't valid
anymore in xxx".

it caused randomly on all statetments, prepare() was ok but execute()
failed:

if ($stmt=$DB->prepare("select something from table where name=?")) {
        $stmt->bind_param('s',$name);
        $stmt->execute(); // HERE PHP WRITE WARNING
                          // AND STMT COINTAIN NO DATA

variables stmt->error, stmt->errno are empty

that's strange but after removing lines 182-187 from
ext/mysqli/php_mysqli.h:

if (!strcmp((char *)__name, "mysqli_stmt")) {\
                if (!((MYSQL_STMT *)__ptr)->mysql) {\
                        php_error(E_WARNING, "Statement isn't valid
anymore");\
                        RETURN_NULL();\
                }\
        }\
} 

it started working without any problems. but of course this 'hack' of
php code isn't good ;)

Please provide a short script, where we can see where the 
error occurs. Also try to catch the errormessages via 
->stmt_error/errno properties.

sorry I've accidently provided wrong mysql version
of course it's mysql 4.1.3 beta

Description:
------------
The problem is in CLI as well as in apache module

I have mysql 4.3.1 and php 5.0.0 installed, use mysqli interface to
work with mysql.

In different scripts in different places (mostly random) I get the
following error:

1) Warning message: Statement isn't valid anymore
2) Statetment result contains no data

Reproduce code:
---------------
appears in randomly different places, all like this:

($DB is mysqli object)

if ($stmt=$DB->prepare("select something from table where name=?")) {
        $stmt->bind_param('s',$name);
        $stmt->execute();

Expected result:
----------------
The same code worked fine on the second server running FreeBSD 5.2.1
without any problems. The main difference between 2 servers I think
that the first one (where bug appears) is a productional server with
many requests to apache/php/mysql, the second one is a development
server with no usage.

Actual result:
--------------
get Warning: Statement isn't valid anymore message and statetment isn't
executed
