Bug description: 2 connections with same server/auth selecting diff dbs
Description:
------------
Generating two database handles to the same server with the same
authentication and selecting different databases for them. They act as a
single connection and will only return results from the last database
selected.
Reproduce code:
---------------
$server ="localhost";
$user="sql_admin";
$pass="password";
$num_query = "SELECT * FROM aqs_users WHERE 1";
$num_db = "aqs";
$anum_query = "SELECT * FROM w_dagent_hierarchy WHERE
row_date='2005-08-08'";
$anum_db = "dbviews";
$num = mysql_connect($server,$user,$pass);
$anum = mysql_connect($server,$user,$pass);
### LINEAR
mysql_select_db($num_db,$num);
mysql_select_db($anum_db,$anum);
$num_res = mysql_query($num_query,$num);
$anum_res = mysql_query($anum_query,$anum);
$num_row = mysql_fetch_row($num_res);
$anum_row = mysql_fetch_row($anum_res);
echo "<pre>"; print_r($num_row); echo "</pre>";
echo "<pre>"; print_r($anum_row); echo "</pre>";
mysql_close($num); mysql_close($anum); unset($num_res); unset($anum_res);
unset($num_row); unset($anum_row);
echo "<hr>";
$num = mysql_connect($server,$user,$pass);
$anum = mysql_connect($server,$user,$pass);
mysql_query("USE aqs",$num);
mysql_query("USE dbviews",$anum);
$num_res = mysql_query($num_query,$num);
$anum_res = mysql_query($anum_query,$anum);
$num_row = mysql_fetch_row($num_res);
$anum_row = mysql_fetch_row($anum_res);
echo "<pre>"; print_r($num_row); echo "</pre>";
echo "<pre>"; print_r($anum_row); echo "</pre>";
mysql_close($num); mysql_close($anum); unset($num_res); unset($anum_res);
unset($num_row); unset($anum_row);
Expected result:
----------------
I would expect both querys to run and display a formatted print_r() of the
results.
Actual result:
--------------
