Oracle9i SQL Reference
Release 2 (9.2)
ALTER TABLE
column_clauses
add_column_clause

"If a column has a default value, then you can use the DEFAULT clause to change the default to NULL, but you cannot remove the default value completely. That is, if a column has ever had a default value assigned to it, then the DATA_DEFAULT column of the USER_TAB_COLUMNS data dictionary view will always display either a default value or NULL."

ALTER TABLE tbl MODIFY f1 DEFAULT NULL;
