啟用快速刷新很棘手,有許多奇怪的限制和無用的錯誤消息.在這種情況下,您需要創建物理化視圖日志WITH ROWID,使用()連接語法,并為每個表添加ROWID.

create table tablea(my_id number primary key,a number);

create table tableb(my_id number primary key,b number);

create materialized view log on tablea with rowid;

create materialized view log on tableb with rowid;

create materialized view mv_myview refresh fast on commit as

select a.my_id,a.a,b.b,a.rowid a_rowid,b.rowid b_rowid

from tableA a,tableB b

where a.my_id = b.my_id(+)

and b.My_id IS NULL;

insert into tablea values(1,1);

commit;

select * from mv_myview;

MY_ID A B A_ROWID B_ROWID
