Use the system view DBA_TAB_COLUMNS to retrieve the field names (all uppercase). You could loop through the fields in the table by declaring a cursor which returned the column name:

SELECT column_name FROM dba_tab_columns WHERE table_name = :a_table
AND owner = :dba_user;

Check the spelling of the fields, I'm doing this off the top of my head.
