How can I insert multiple rows into oracle with a sequence value?

Question

I know that I can insert multiple rows using a single statement, if I use the syntax in this answer.

However, one of the values I am inserting is taken from a sequence, i.e.

insert into TABLE_NAME (COL1,COL2) select MY_SEQ.nextval,'some value' from dual union all select MY_SEQ.nextval,'another value' from dual ; 

If I try to run it, I get an ORA-02287 error. Is there any way around this, or should I just use a lot of INSERT statements?

EDIT:
If I have to specify column names for all other columns other than the sequence, I lose the original brevity, so it's just not worth it. In that case I'll just use multiple INSERT statements.

Answer 1

This works:

insert into TABLE_NAME (COL1,COL2) select my_seq.nextval, a from (SELECT 'SOME VALUE' as a FROM DUAL  UNION ALL  SELECT 'ANOTHER VALUE' FROM DUAL)
