Check the topic "Query" in the "Expert" manual. Also, you need not
insert; you could use a global (java.util.List) variable (again:
"Expert") for collecting these objects.

Sigh. You are asking absolutely basic questions. How about reading the
"Expert" manual and studying the examples? You won't be able to avoid
this, and the earlier you do it, the better.

There is no loss of data except for inserting equal facts in a
non-default operational mode for your session.
