Query of SB | Mat. Views

Materialized View Query is editable in SB RHS for SB|Mat. Views. This is also a bug in 12.8 GA version.

Some MVs can be updated. This, for example:

CREATE TABLE TABLES AS SELECT * FROM DBA_TABLES;

ALTER TABLE TABLES ADD (
CONSTRAINT TABLES_PK
PRIMARY KEY
(OWNER, TABLE_NAME);

CREATE MATERIALIZED VIEW LOG ON TABLES
WITH PRIMARY KEY;

CREATE MATERIALIZED VIEW TABLES_MV
REFRESH COMPLETE ON DEMAND
WITH PRIMARY KEY
FOR UPDATE
AS SELECT * FROM TABLES;

Oops! You mean the query tab! Got it. Thanks.
