mviewlog

materializes connect a must for a materialized view.

I can see materialized view not a newspaper materialized in the schema of object I'm working.

I still have to read documentation correctly.

Thank you

If you want to perform a QUICK refresh then MV journal is required.

Example of

SQL > create materialized view immediate emp_mv
full 2 refresh
3 on request
4, as
5. Select deptno, sal sum (sal)
6 of PEM
Group 7
8 by deptno;

Materialized view created.

SQL > select * from emp_mv;

DEPTNO SAL
---------- ----------
30 58450
20 50051
10 17450

SQL > drop materialized view emp_mv;

Materialized view is deleted.

SQL > create materialized view immediate emp_mv
2 fast refresh
3 on request
4, as
5. Select deptno, sal sum (sal)
6 of PEM
Group 7
8 by deptno;
WCP
*
ERROR on line 6:
ORA-23413: table 'ARBORU '. "" EMP "isn't a materialized view log
