The View_CMS_Tree_Joined view is a system view combining several tables of the database. Doing a "SELECT *" against that view would pull back a tremendous amount of records and data, depending on the size of your site. I highly recommend looking into your web parts / data sources and specifying the specific columns you need. Most likely, you have a repeater or other web part that is pulling the data without filtering out any of the fields.
We also have a n open source tool called KInspector which can help you identify where you should specify specifc records. You find more about KInspector here:
