This example creates a multiset queue table with constraints defined at the column level:

    CREATE MULTISET TABLE qtbl_3, QUEUE,
     NO BEFORE JOURNAL,
     NO AFTER JOURNAL (
      qits  TIMESTAMP(6) NOT NULL DEFAULT CURRENT_TIMESTAMP(6),
      col_2 INTEGER,
      col_3 INTEGER CHECK (col_3 > 10))
    PRIMARY INDEX (qits);

This queue table permits duplicate rows. The system uniquely identifies its rows, including duplicates, by their internally-generated ROWID value.
