HOW TO DELETE PARTICULAR TRIPLE SET FROM Oracle SEMANTIC TABLES in 11g

Question

Can somebody help us how to delete a particular set of triples from Oracle(11g) semantic that we have. Because we noticed that few triple belongs to particular data sets were wrongly loaded so we need to remove only those triples.
Usually we delete all triples including others such and reload them again along with new triples. We would like to avoid this as we go to production.
Otherwise When we insert a set of triples belongs to a particular data set, is it possible to know what ids Oracle assigned to that set? Can we delete by id? Just a thought.

Hi,
It is very strange. I got an email in my inbox saying that you want to find out
IDs of triples that belong to RNAIDB data set like the following.
"<http://www.lscdd.lilly.com.sg/lscdd/RNAIDB/...../.../:>".
This forum does not have your message somehow.
Assume you have asked such an question :), my answers are
1) from a modeling perspective, it is not a very good idea to encode
semantics in the URI lexical form itself. A URI should be treated
as a symbol.
2) now assume you have a valid reason for doing this, you can try something like the following.
CREATE INDEX testdel_sub_idx ON tstdel (triple.GET_SUBJECT());
-- You can then get the rowid out for those offending rows.
select rowid
from tstdel t
where t.triple.GET_SUBJECT() like '<urn:su%'
-- Or you can remove them directly.
delete from tstdel t
where t.triple.GET_SUBJECT() like '<urn:su%'
;
