I am using Drupal 7 and Views 7.x-3.7 . I am trying to display posts on my site using a SQL query that looks like this:

SELECT DISTINCT node.title AS node_title, node.nid AS nid, node.language AS node_language

FROM 

{node} node

ORDER BY node_title ASC

The problem with this query is that if I have multiple posts with the same title,then all are being displayed because the nid, which is the primary key, was added by Drupal. I have been trying to remove the nid by using the hook_views_query_substitutions() method, but I have had no success. The method is getting called, but my query is not being updated.

I call zz_views_api() from my zz.module, and have the following zz.views.inc

function zz_views_query_substitutions($view) {
  // description of  zz_views_query_substitutions().

  return array(
    'node.nid AS nid,' => ' ',
  );
}

I think this is a similar situation to a question I asked a little while ago.

I solved it by using hook_views_query_alter() to remove the fields I didn't need in the query. In your case, it would probably look like:

function MYMOODULE_views_query_alter(&$view, &$query) {
  if ($view->name == 'MY_VIEW') {
    unset($query->fields['nid']);
  }
}

dpm() the $query to see what array keys are in $query->fields if that doesn't work.

  • This plus enabling pure distinct works, thanks. Can anybody still explain why the query substitution does not work ? – zzz711 May 6 '14 at 15:19
