Can NOT create Materialized View

[M. Mehta]

It seems that you can not create a materialized view if you are using
outer joins...can someone please verify this?

Thanks
M. Mehta

Please follow my example below:

created 2 tables:

select * from emp;

EMP_ID DEPT_ID SAL
---------- ---------- ----------
1 1 20000
2 1 50000

select * from dept;

DEPT_ID DEPT_NAME
---------- ----------
1 HR
2 IT
3 CC

create materialized view (with out outer join):

6 /

SQL> drop materialized view mv_test;

I gave the following permission: grant create materialized view to hr;
and I still get the following error:ORA-12054: cannot set the ON
COMMIT refresh attribute for the materialized view.

Here is what I am doing: ( Release 9.2.0.4.0 )

CREATE MATERIALIZED VIEW mv_test BUILD IMMEDIATE REFRESH COMPLETE
ON COMMIT AS
SELECT COUNT(*), b.dept_id, b.dept_name, SUM(sal) salary,COUNT(sa l)
FROM EMP a, DEPT b
WHERE a.dept_id = b.dept_id (+)
GROUP BY b.dept_id, b.dept_name

Maybe will help, if you create on base tables "MATERIALIZ ED VIEW LOG"
