Operating system: Solaris 9/10
PHP version: 5.2.5
PHP Bug Type: Sybase-ct (ctlib) related
Bug description: Incurred fault #6 - if returned textfield ist empty
Description:
------------
The problem can reproduced on Solaris 9 and Solaris 10.
If I compile php with
./configure \
--prefix=/usr/local/wwwbin/php-5.2.5 \
--with-apxs2=/usr/local/wwwbin/apache/bin/apxs \ (Apache 2.2.6)
--with-sybase-ct=/opt/csw (freetds-version 0.64 from blastwave)
and perform this simple query:
select DC_Rights from Resource R where R.Resource_ID = 123;
(DC_Rights type text, Resource_ID = 123 exists, should return "(empty) not
NULL, works via tsql)
i get "Incurred fault #6".
Reproduce code:
---------------
<?php
require("DBConnection.cls.php"); // database connection
$db=new DBConnection(); // new object
$test = "set textsize 262144";
echo $test."<br />";
//$db->submitQuery($test); flush();
$query = "select DC_Rights from Resource R where R.Resource_ID = 122"; //
expected Result: NULL
flush();
$res_id = $db->submitQuery($query); // works!
$query = "select DC_Rights from Resource R where R.Resource_ID = 123"; //
expected Result: ""
flush();
$res_id = $db->submitQuery($query); // doesn't work. Apache: Segmentation
fault (11)
echo "done!";
flush();
exit();
?>
Expected result:
----------------
set textsize 262144
select DC_Rights from Resource R where R.Resource_ID = 122
select DC_Rights from Resource R where R.Resource_ID = 123
done!
Actual result:
--------------
