+# Get User's Roles from User Name
+
+GlideQuery's can greatly simplify extracting information from queries, especially when dot walking.
+
+This query retrieves a user's roles, and returns an array of objects with the the role's display
+value, the role's active status, the user's display value, and the user's email.  Adding more
+fields is trivial with this format, and the query stream is very easy to follow.
