If you want your table to be always free of duplicates, consider using SET instead of MULTISET option in the table definition. That's a typical
feature of TD you probably won't find in Oracle.
SET does add performance overhead with each DML, though, which might be quite visible with larger tables. In that case you might be better off
using MULTISET and the query as above scheduled to run after all DML.
