How to get the path to a node
You don't need entity_metadata_wrapper in this case.
You can get path of node using url() function.

$node = node_load($row-&gt;{$field-&gt;field_alias}); 
$nid = $node-&gt;nid; 
$path_to_node = url("node/$nid");


And I agree with Елин Й's answer. You can use l() function. It already uses url() function. So you can build link with node pathauto alias using:

$node = node_load($row-&gt;{$field-&gt;field_alias}); 
print l(t('Go to Node'), 'node/' . $node-&gt;nid);
