ORA-03222:

average row size and row count must be greater than zero
Cause: Either a bad value passed to dbms_space.create_table_cost() or explain plan did not pass through size information.
Action: Check the row size parameter in dbms_space.create_table_cost(). For explain plan, make sure statistics have been computed for all source tables in the CREATE TABLE AS SELECT statement.
