I did a full export of the database with the new export utility from 10g.

expdp userid=sys dumpfile=full.dmp full=y

When i imported in a new database. Everything was ok, except the owners dont have any table triggers

impdp userid=sys dumfile=full.dmp full=y
impdp userid=sys dumfile=full.dmp schemas=demo40

Both commands did not import the table trigger.

Is there a way to import only the trigger?
Why this happened?

Note: I did this with
I patched the database to this weekend.

Do you think the patched version will import the triggers?
