problem:

trying to execute a query

description:

somewhere in the script i try to execute a simple select query like 
select * from users;
and i got an empty result although the table contain data
and the i have a database link.
I've tried a bug fix like:
 /**
  * *fix without it the query fails	 
  */

    mysqli_close ( $db->link_id );
    $link_id = mysqli_connect($db_host, $db_username, $db_password, $db_name, $db_prefix, $p_connect);


It's works only for one query and after that i need to use the fix again



if this bug is reported , although i couldn't find it, please post the bug id # for reference

Reproduce code:
---------------
$result = mysqli_query($link_id, 'SELECT g_id FROM groups');

Expected result:
----------------
to have some rows (i know i have them cause i check it in command client)

Actual result:
--------------
rows = 0
