ORA-14121

Error: ORA-14121: MODIFY DEFAULT ATTRIBUTES may not be combined with other operations

Causa: ALTER TABLE or ALTER INDEX statement attempted to combine MODIFY DEFAULT ATTRIBUTES with some other operation (for example, ADD PARTITION or PCTFREE) which is illegal.

Acción: 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.
