Oracle Error Message
ORA-14121: MODIFY DEFAULT ATTRIBUTES may not be combined with other operations
Reason for the Error
ALTER TABLE or ALTER INDEX statement attempted to combine MODIFY DEFAULT ATTRIBUTES with some other operation (e.g. ADD PARTITION or PCTFREE) which is illegal
Solution
Ensure that MODIFY DEFAULT ATTRIBUTES is the sole operation specified in ALTER TABLE or ALTER INDEX statement; operations other than those dealing with partitions, default attributes of partitioned tables/indices or specifying that a table be renamed (ALTER TABLE RENAME) may be combined at will
