Question

See the code below, there are two databases connections.

First it get the data from first connection and then insert into second database connection but it will not insert – I can an error saying Unknown column 'fullname' in 'field list'

When I tried SQL query manually in phpMyAdmin and it work fine…

$db_new = mysql_connect('localhost', 'root', 'password');
if (!mysql_select_db("menu_new", $db_new)) {
    die("Cant connect menu_new DATABASE");
}

$db_old = mysql_connect('localhost', 'root', 'password');
if (!mysql_select_db("old_menu", $db_old)) {
    die("Cant connect old_menu DATABASE");
}

$SQL_old = "SELECT * FROM old_table";
$q = mysql_query($SQL_old, $db_old);

while ($row = mysql_fetch_assoc($q)) {
    $name = $row['name']; 

    $SQL = "INSERT INTO tbl_name (fullname) values ('$name')";

     //Problem Here - It wont insert into second database
     mysql_query($SQL, $db_new) or die(mysql_error($db_new));
}

Thanks @Konerak for suggestion and that does work!

To Insert/Select data from Database connection, you will have to include database name before the table name.

For Example

From:

mysql_query("INSERT into tbl_name (fullname) values ('1')", $db_new) or die(mysql_error($db_new));

To:

mysql_query("INSERT into menu_new.tbl_name (fullname) values ('1')", $db_new) or die(mysql_error($db_new));

That is really odd though.
