Alter table shrink or alter table move failing with the error ORA-10662 Segment has long columns

in Database Administration (MOSC) 2 commentsAnswered

Alter table shrink or alter table move failing with the error ORA-10662 Segment has long columns and ora-00997 : illegal use of LONG datatype.

10662.00000 - "Segment has long columns"

Cause: Shrink was issued on a segment with long columns. This is not supported.

My question is : how to get rid of this error and perform the table re-org with "Alter table move" or "Alter table shrink" command?

Howdy, Stranger!
