materialized view ON COMMIT REFRESH - 942 error

Tony Adolph


Hi all,

I've been reading this guide / that guide trying to get this problem fixed,
but have failed :-( So I've created a simple example to illustrate my error
(lack of knowledge).

My master table, xxx is owned by billing_api and I want to replicate this to
user tony. Both schemas (in my example) are on the same database. I can't
create a fast refresh on commit MV. See the following:

Version: Oracle9i Enterprise Edition Release - 64bit

The problem:

connect billing_api

create table xxx (id number not null, val varchar2(10));
alter table xxx add constraint pk_xxx primary key (id) using index;
grant select on xxx to tony;

create materialized view log on xxx;

 for i in 1 .. 3 loop
   insert into xxx (id,val) values (i, 'val'||i);
 end loop;

select * from xxx;

ID                         VAL
-------------------------------------- ----------
1                          val1
2                          val2
3                          val3

connect tony

select PRIVILEGE from user_sys_privs;

select * from billing_api.xxx;
ID                         VAL
-------------------------------------- ----------
1                          val1
2                          val2
3                          val3

create materialized view xxx
build immediate
refresh fast on commit
select * from billing_api.xxx
18:37:16 ORA-00942: table or view does not exist

At this point I did a lot of RTFMing, but couldn't resolve the problem. I
then resulted to hacking and tried creating the MVLog with/without PK/rowid,
with/without INCLUDING NEW VALUES, with/without SEQUENCE. But am obviously
missing something key.

Any pointers would be appreciated. At the moment I'm just trying to get all
types of MVs working so that I can make a reasonably educated choice on how
to use them later on.

Any pointers to a good doc, would also be useful.
