Re: Can NOT create Materialized View

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(sal) FROM EMP a, DEPT b
WHERE a.dept_id = b.dept_id (+)
GROUP BY b.dept_id, b.dept_name
