Answer 1

I had that problem and solved it with prefixing the table name with the database name, so

 select * from database.table

Answer 2

Unless you have the password incorrect and need to fix it, run a GRANT statement to grant access to your database user:

GRANT ALL PRIVILEGES ON aTable.* TO xxx@localhost IDENTIFIED BY 'password_for_xxx';

The above grants all privileges. It's often better to restrict to only what's needed. For example, if you only intend to SELECT, but not modify data,

GRANT SELECT ON aTable.* TO xxx@localhost IDENTIFIED BY 'password_for_xxx';

Update

Since you have identified the database name as dedbmysql, change your mysql_select_db() call to:

$db = mysql_select_db("dedbmysql", $con);

Following this, the GRANT statements above are probably unnecessary, as your host may have already worked out the correct database permissions.
