ORA-25186: INCLUDING clause specified for index-organized table without OVERFLOW

What triggered the Error:

CLUDING clause of a CREATE TABLE is an valid option only for index-organized tables with OVERFLOW clause (at creation time) or if an OVERFLOW segment already exists (at ALTER time).

What should we do to fix it:

ecify OVERFLOW clause for the index-organized table : For ALTER, perform ADD OVERFLOW first.
