How to show only updated nodes in VIEWS I am creating a View in Drupal 7 for a particular content type.
I want to add filter to show nodes which are updated. When I am adding Node Update Date field, it is asking for operator and Value to compare with. But I can not provide Updated date of each node.

Then I also tried hook_views_query_alter to alter the query. When I am adding Query Value to node.created field it take it as a string or you can say Value.

Can someone help me to achieve this?
You may be able to use hook_views_query_alter to load only nodes which have node.updated value equal to NULL or ''.
