Description:
------------

When a LOAD DATA LOCAL INFILE query is run after a previous SELECT query on the 
same mysqli handle, mysqli::query returns false even though the LOAD DATA query 
is successful.

Additionally, PHP outputs two warnings during the mysqli::query call:

PHP Warning:  mysqli::query(): (00000/0):  in /path/to/script.php on line 16

Warning: mysqli::query(): (00000/0):  in /path/to/script.php on line 16


Properties of the mysqli object, such as errorno and affected_rows, indicate 
success.

If the LOAD DATA query is the first query run on a particular mysqli object, it 
works fine.

We are using the mysqlnd lib.

Configuration:

./configure  --prefix=/usr/local --with-xmlrpc --with-apxs2 --with-
mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-curl --with-curlwrappers --
enable-bcmath --with-gd=/usr --with-mcrypt=/usr/local --enable-mbstring --with-
zlib --with-iconv --enable-soap --enable-ftp --without-sqlite --with-xsl --
enable-pcntl --enable-sockets --with-openssl


This may be the same as inactive Bug #47387.

Test script:
---------------
$db = new mysqli($host,$user,$pass,$dbname);

$tempfile = tempnam("/tmp","loaddata_");

file_put_contents($tempfile, "1");

$db->query("create table if not exists LoadDataTest (Column1 int unsigned not null primary key)");
$db->query("select * from LoadDataTest limit 1"); //LOAD DATA works properly without this
$result = $db->query("load data local infile '$tempfile' replace into table LoadDataTest (Column1)");

if ($result) print "Load data success.\n";
else print "Error {$db->errno}: {$db->error}\n";

unlink($tempfile);


Expected result:
----------------
mysqli::query returns result object

Actual result:
--------------
mysqli::query returns false
