$db1 = mysql_connect(”host”,”user”,”pwd”)
mysql_select_db(”db1name;, $db1);
$res1 = mysql_query(”query”,$db1);


$db2 = mysql_connect(”host”,”user”,”pwd”, true)
mysql_select_db(”db2name;, $db2);
$res2 = mysql_query(”query”,$db2);

So mysql_connect has another optional boolean parameter
which indicates whether a link will be created or not. as we
connect to the $db2 with this optional parameter set to
‘true’, so both link will remain live.

now the following query will execute successfully.
$res3 = mysql_query(”query”,$db1);
