Using the term PIVOT or UNPIVOT as an alias in a procedure gives a syntax error when trying to run in Toad.

"ERROR line 4679, col 95, ending_line 4679, ending_col 95, Found ',', Expecting: XML -or- ("

This is only a problem in some situations. Example:

--This Works:
SELECT pivot.* FROM DUAL pivot;

--This Works:
DECLARE
CURSOR c1
IS
SELECT pivot.* FROM DUAL pivot;
BEGIN
NULL;
END;

--This DOES NOT Work:
CREATE OR REPLACE PROCEDURE TEST
IS
CURSOR c1
IS
SELECT pivot.* FROM DUAL pivot;
BEGIN
NULL;
END;
