Bad query

I fixed problem with the query to display all downloads... there was a problem with the "join upload.description with files_download.filename"

Here are the right queries :

  if(user_access('view all downloads count')) {
    $result = db_query("SELECT fd.filename, fd.count, fd.timestamp, u.nid, n.type FROM {file_downloads} fd JOIN {files} f ON f.filename = fd.filename JOIN {upload} u ON f.fid = u.fid JOIN {node} n ON n.nid = u.nid"  . tablesort_sql($header), $fileDirectoryPath);
  }
  else {
    $result = db_query("SELECT fd.filename, fd.count, fd.timestamp, u.nid, n.type FROM {file_downloads} fd JOIN {files} f ON f.filename = fd.filename JOIN {upload} u ON f.fid = u.fid JOIN {node} n ON n.nid = u.nid WHERE n.uid = %d" . tablesort_sql($header), $fileDirectoryPath, $user->uid);
  }
