Do you mean, how do you assign the next value of the sequence to a the key column when you insert a row?

To do this, you need to write a before-insert per-row trigger that sets the value of the key column to the next-val of the sequence. (There is no declarative way to do this that I know of (ala an Access Autonumber).)
