Replacing field result with hook_views_pre_execute when replacing SQL query
From your description, you are trying to display the aliased path of the current page using a view.If you are trying to encourage users to deep-link to your site, a PHP code snippet might be a better approach. (Drupal often encourages complex answers to simple requirements.)

Using aliased links means that the links may be broken if the alias changes (as with a change in the page title) unless the old aliases are retained. In that case, multiple aliases will exist for each page. Deep links should use the un-aliased url.
