Hello,
it seems that Oracle (11R2) doesn't add the Start and End timestamp columns
and permit statement like
select * from tt
union
select * from tt
AS OF TIMESTAMP (SYSTIMESTAMP - INTERVAL '6' SECOND)
minus
select * from tt
VERSIONS BETWEEN TIMESTAMP (SYSTIMESTAMP - INTERVAL '6' second) and
SYSTIMESTAMP;
Regards
PAscal
