   You can try this for get parent page template name
   /********** GET PAGES BY PARAMS ************/
   
   /*-- Get root parent of a page --*/
   function get_root_page($page_id) 
   {
       global $wpdb;
   
       $parent = $wpdb->get_var("SELECT post_parent FROM $wpdb->posts WHERE post_type='page' AND ID = '$page_id'");
   
       if ($parent == 0) 
           return $page_id;
       else 
           return get_root_page($parent);
   }
   
   /*-- Get page name by ID --*/
   function get_page_name_by_ID($page_id)
   {
       global $wpdb;
       $page_name = $wpdb->get_var("SELECT post_title FROM $wpdb->posts WHERE ID = '$page_id'");
       return $page_name;
   }
   
   /*-- Get page ID by Page Template --*/
   function get_page_ID_by_page_template($template_name)
   {
       global $wpdb;
       $page_ID = $wpdb->get_var("SELECT post_id FROM $wpdb->postmeta WHERE meta_value = '$template_name' AND meta_key = '_wp_page_template'");
       return $page_ID;
   }
   
   /* -- Get page ID by Custom Field Value -- */
   function get_page_ID_by_custom_field_value($custom_field, $value)
   {
       global $wpdb;
       $page_ID = $wpdb->get_var(" 
           SELECT wposts.ID
           FROM $wpdb->posts wposts, $wpdb->postmeta wpostmeta
           WHERE wposts.ID = wpostmeta.post_id 
           AND wpostmeta.meta_key = '$custom_field' 
           AND (wpostmeta.meta_value like '$value,%' OR wpostmeta.meta_value like '%,$value,%' OR wpostmeta.meta_value like '%,$value' OR wpostmeta.meta_value = '$value')        
           AND wposts.post_status = 'publish' 
           AND wposts.post_type = 'page'
           LIMIT 0, 1");
   
       return $page_ID;
   }
