Using this example below of a simple pivot query, I'm trying to also add a 4th column that sums the previous 3 columns.  So the result looks like this,

CLUSTER  INDEX TABLE SUM
10             468     374      852

select * from (
   select object_type
   from dba_objects
)
pivot
(
   count(object_type)
   for object_type in ('CLUSTER', 'INDEX', 'TABLE')
);

or, you can use the default aliases, but then you'll need to put them in double quotes


SELECT x.*, "'CLUSTER'" + "'INDEX'" + "'TABLE'" AS SUM
  FROM (SELECT *
          FROM (SELECT object_type FROM dba_objects) PIVOT (COUNT(object_type)
                                                     FOR object_type
                                                     IN ('CLUSTER', 'INDEX', 'TABLE'))) x;
