db_query to drupal variable I have a the following query:

function background_audio_file_query($path) {
  $result = db_query("SELECT uri
    FROM `file_managed`
    WHERE `filemime` = 'audio/mpeg'
    LIMIT 1 , 30",
    array(':uri'=&gt;$path))-&gt;fetch();

return $result;
}


How can I pass this to a Drupal variable?  I am assuming variable_set() but I am having trouble with the syntax.  Could anyone lend a hand?
If you want to set a variable with the URI returned from the query, you just execute code similar to the following one:

variable_set('variable name', $result-&gt;uri);


Replace "variable name" with the name you want to give to the Drupal variable, which is the same one you pass to variable_get().
