SQL query?

Hello,
I'd like to create a query on table which has 20 fields (F1,F2,...F20), but I need to exclude five fields from the query and I can't use rest of fields explicitly.
So I try do that like :
SELECT (SELECT COLUMN_NAME||',' FROM USER_TAB_COLUMNS WHERE TABLE_NAME='MYTABLE' AND COLUMN_NAME NOT IN ('F1','F17','F18','F19','F20'))
FROM MYTABLE;
But it doesn't work.
How could I fix this expression to get proper result? Thanks,
