The Query Results tree has the following branches:
This branch lists the columns that are in the query results as they were returned from the query. As you make changes to the query results in the active window, this branch remains unchanged. It serves as the source.
This branch lists the columns as they currently appear in the active window. As you make changes to the query results in the active window, the changes are reflected in this branch of the tree. There are three nodes in the Layout branch:
Lists the columns that you have selected to be summarized along the top of the query results.
Lists the columns that you have selected to be summarized along the left side of the query results.
Dynamically lists and relists the query results columns as they appear after each move that you make using the Query Results Explorer or the Layout Designer.
