Create materialized view in SE referring table in EE

Hi DBAs,
I am trying to create a Materialized view on Oracle 10g Standard Edition which is installed on Linux Debian Lenny.
The master table is on Oracle 10g Enterprise Edition installed on Red Hat Linux 4.1.2.
When I run,
create materialized view t1 build immediate refresh fast as (select * from aksharaemsmigrated.t1@db102)
i get,
ORA-12028: materialized view type is not supported by master site
When I run,
create materialized view t1 build immediate refresh fast on commit as (select * from aksharaemsmigrated.t1@db102);
I get,
ORA-01031: insufficient privileges
When I run,
select * from aksharaemsmigrated.t1@db102
I get,
the rows from aksharaemsmigrated.t1@db102
NOTE: 'db102' is remote DB on 10g EE for which I created db link.
I am able to create Mview for local table.
Is this not supported? I mean creating Mview on Oracle SE referring base table from Oracle EE.
I have to give solution soon. Can you please throw some light.
Regards,
Vijay

Don't put select statement inside parantheses.
Test these
create table x1 as select * from aksharaemsmigrated.t1@db102;
create materialized view t1 build immediate refresh fast as select * from aksharaemsmigrated.t1@db102 ;Note that you cannot create an MV that is REFRESH ON COMMIT when across Databases.
See my explanation at http://hemantoracledba.blogspot.com/2008/06/mvs-with-refresh-on-commit-cannot-be.html

Create materialized View fails with "table or view does not exist"

DB: 10.2.0.4
OS: Win 2003
Hi,
Here in my tests, i have 2 databases (A(source) and B(backup)), and i am trying to create an mview in database B to replicate data from one test table from database A, only for test purpose. I'm getting the error "table or view does not exist" when i try to create a mview with REFRESH FAST. Here is my code:
CREATE MATERIALIZED VIEW TESTES.TAB_TESTES_REPLIC_MVIEW_02
REFRESH FAST
START WITH TO_DATE('21/02/2012 18:50:00', 'DD/MM/YYYY HH24:MI:SS')
NEXT SYSDATE + 1/24/60
WITH PRIMARY KEY
AS SELECT REGISTRO1,
REGISTRO2
FROM TESTES.TAB_TESTES_REPLIC_MVIEW_02@DB_LINK_ORA10;
The dblink is workig fine(dblink user has select privilege on TESTES.TAB_TESTES_REPLIC_MVIEW_02), and i have created the mview log on database A.
Where is my mistake.
Thanks a lot.
Edited by: Fabricio_Jorge on 21/02/2012 19:06

I found the solution.
I had to grant SELECT on the mview log. The name is avaiable in DBA_MVIEW_LOGS

Creating Materialized View in Toad

As with every new endeavor - come new questions.
I am trying to create a materialized view via toad (first time doing this). Now - toad is great, since it provides a kind-of wizard interface. Hence, one doesn't have to completely code in the create statement, with all of the options, etc.
Instead, in toad, one can (via the schema browser), go into the Materialized Views tab and click on create new. This opens a window with 6 tabs: Basic Info, Refresh Info, Physical Attributes, Query, Partitions & Subpartition Template.
In the Basic Info, one can put a check mark next to some of the following options:
-Build Deffered
-Parallel
-Cache
-Logging
-Using index
-Allow updates
etc.
I have read that build deferred refers to whether or not you would like the view to be created automatically or to be deferred.
Anyways, I tried to find Toad documentation to explain each of the options in-detail. No success. Hence, am researching each part piece by piece.
But - here is my question:
In the Query tab, we are asked to specify a query. I am assuming that the query does not have to be a full query, beginning with CREATE MATERIALIZED VIEW mv_table1 REFRESH FAST etc...
Since in this 'wizard', we are providing the MV name at the top of the dialog box, we are checking the 'options' in the other tabs, etc.
And so, I assumed that the query should merely be a select query in the window mentioned above.
So I entered the following:
select * from table1@remote_db;
When I go to verify the syntax, I get the error message: ORA_00911: invalid character. It seems to be pointing to my db_link (remote_db). I have been using this link throughout many places, w/o any problems.
Has anyone created a MV in toad before? Any links to good toad documentation would be helpful as well.
Thanks.

(This is fun... ;))
For anyone endeavoring this in the future, below I have attached the prerequisites required in order to create a materialized view (can also be found @ http://download-uk.oracle.com/docs/cd/B14117_01/server.101/b10759/statements_6002.htm):
Prerequisites
The privileges required to create a materialized view should be granted directly rather than through a role.
To create a materialized view in your own schema:
You must have been granted the CREATE MATERIALIZED VIEW system privilege and either the CREATE TABLE or CREATE ANY TABLE system privilege.
You must also have access to any master tables of the materialized view that you do not own, either through a SELECT object privilege on each of the tables or through the SELECT ANY TABLE system privilege.
To create a materialized view in another user's schema:
You must have the CREATE ANY MATERIALIZED VIEW system privilege.
The owner of the materialized view must have the CREATE TABLE system privilege. The owner must also have access to any master tables of the materialized view that the schema owner does not own (for example, if the master tables are on a remote database) and to any materialized view logs defined on those master tables, either through a SELECT object privilege on each of the tables or through the SELECT ANY TABLE system privilege.
To create a refresh-on-commit materialized view (ON COMMIT REFRESH clause), in addition to the preceding privileges, you must have the ON COMMIT REFRESH object privilege on any master tables that you do not own or you must have the ON COMMIT REFRESH system privilege.
To create the materialized view with query rewrite enabled, in addition to the preceding privileges:
If the schema owner does not own the master tables, then the schema owner must have the GLOBAL QUERY REWRITE privilege or the QUERY REWRITE object privilege on each table outside the schema.
If you are defining the materialized view on a prebuilt container (ON PREBUILT TABLE clause), then you must have the SELECT privilege WITH GRANT OPTION on the container table.
The user whose schema contains the materialized view must have sufficient quota in the target tablespace to store the master table and index of the materialized view or must have the UNLIMITED TABLESPACE system privilege.
When you create a materialized view, Oracle Database creates one internal table and at least one index, and may create one view, all in the schema of the materialized view. Oracle Database uses these objects to maintain the materialized view data. You must have the privileges necessary to create these objects.

Error while creating materialized view which using database link

Helo!
I'm getting error "ORA-00942: table or view does not exist" when I want to create materialized view.
Details:
1. On destination database I create a database link:
CREATE DATABASE LINK SDATABASE
CONNECT TO MYUSER
IDENTIFIED BY MYUSERPASS
USING 'ORCL';
=> Command "SELECT * FROM TABLE1@SDATABASE" returns data normally!
2. On source database I create MATERIALIZED VIEW LOG:
CREATE MATERIALIZED VIEW LOG
ON TABLE1
WITH PRIMARY KEY
INCLUDING NEW VALUES;
3. Now, when I want to create MATERIALIZED VIEW on destination database:
CREATE MATERIALIZED VIEW TABLE1
REFRESH FAST
START WITH SYSDATE
NEXT SYSDATE + 1/1440
WITH PRIMARY KEY
AS SELECT * FROM TABLE1@SDATABASE;
...I get error "ORA-00942: table or view does not exist"!
How is that possible if command "SELECT * FROM TABLE1@SDATABASE" returns data normally?
Thanks,
Voranc

And, I'm using Oracle 10g.

How to create materialized view based on a view?

Hi,
I hope this is not very far fetched idea.
I have a very complex view and I would like to replicate it 'in place' that is I would like to make a materialized view that is based on this view complex view. I would like to use this materialized view (i.e table) to query data instead of using the original view, since it takes Oracle some 10-15 seconds to execute my query on the original view and I am not allowed to create indexes on most of the tables that are included in the original view.
Can this be done?
Best regards,
Tamas Szecsy

The best way to do this is to create a materialzed view based on the underlying code of the original view. If you don't have this handy, issue the following in sqlplus:
select text
from user_views
where view_name = 'NAME_OF_VIEW'
You can then cut and paste the sql statement into your create materialized view statement.
Please note, you will probable have to set the long parameter to a higher value to reveal the complete statement for example:
SQL> set long 2048

How to CREATE MATERIALIZED VIEW LOG (MV fast refresh) with some JOINS

Hi @ all,
i'm trying to create a MATERIALIZED VIEW LOG for a fast refresh of a MATERIALIZED VIEW.
It works fine with a simple Request in the MATERIALIZED VIEW:
CREATE MATERIALIZED VIEW MV_ZOTD43_P
TABLESPACE GDII
BUILD IMMEDIATE
REFRESH FORCE AS
SELECT * FROM ZOTD43_P;
COMMIT;
CREATE MATERIALIZED VIEW LOG ON ZOTD43_P
TABLESPACE "GDII"
WITH PRIMARY KEY, ROWID, SEQUENCE INCLUDING NEW VALUES;
call DBMS_MVIEW.REFRESH('MV_ZOTD43_P', 'f');
But when I use a complex SQL-Request with some JOINS (one of the Table with spatial Data) in the MATERIALIZED VIEW, I get an error:
CREATE MATERIALIZED VIEW MV_TEST
TABLESPACE GDII
BUILD IMMEDIATE
REFRESH FORCE AS
SELECT lptd04_p.sst_nr AS sst_nr,

*Cause: The materialized view log does not exist or cannot be used. PCT
refresh is also not enabled on the materialized view
*Action: Use just REFRESH, which will reinstantiate the entire table.
If a materialized view log exists and the form of the materialized
view allows the use of a materialized view log or PCT refresh is
possible after a given set of changes, REFRESH FAST will
be available starting the next time the materialized view is
refreshed.
Am I doing something wrong or is it not possible CREATE MATERIALIZED VIEW LOG when the MATERIALIZED VIEW got some JOINS?

Thanks for the link Alessandro ,
the error seems something to do with the Column-Type SDO_GEOMETRY, so

Error on creating Materialized view.

Hi,
I don't understand why it happens...
When I tried to creating materialized view, it shows a error "ORA-01013: User requested cancel of current operation".
I don't understand why it happens. I just waited it successfully created. But I didn't press any button.
Does it matter of size of joining table? I had same issue before. At that time I just removed some tables from the joining condition, this error was gone.
But at this time, I cannot exclude any other tables the select statement
Can anyone help me this issue, please?

Hi,
11g ( 11.2.0.3 ) has a problem with materialized views based on ROWID, resulting in the problem you mentioned.
A workaround is creating the MV's based on primary keyl.
There is also a patch available on MOS, to solve the problem ( thanks to a very long SR from me :-) )
It is known as bug 13657605 and the patch for it has the same number.
Remember to read the README, as this patch is only for 11.2.0.3 !!

Problems in creating Materialized View from 10g R2 to 11g

Hi,
We have two databases in 10g Release 2. These databases are on two different servers and we use
Materialized views to replicate data between these servers. We are currently using 64 bit version of
oracle 10g release 2 for LINUX.
Oracle Database 10g Release 10.2.0.1.0 - 64 bit Production
PL/SQL Release 10.2.0.1.0 - Production
CORE 10.2.0.1.0 Production
TNS for Linux: Version 10.2.0.1.0 - Production
NLSRTL Version 10.2.0.1.0 - Production
We use CENTOS 5 - 64 bit edition
We upgraded one of the databases to 11g (We exported the data from old database and
imported it in new database) . Then we tried to create a Materialized view with incremental refresh
on it where the base table is in the second Oracle 10g database.
The problem is that it is not letting us create the view with FAST Refresh. It kept on giving ORA-12028
error. We tried different remedies suggested on forums like creating a view with ROWID, but still it
continued giving us the same error. We also synchronized the characterset of Oracle 10g and Oracle 11g
installations but still it did not work.
Our base table size is pretty large (over 10 Million records) and if we do a full refresh, it takes hours to
refresh it.
Without incremental refresh, we will not be able to fucntion, and to upgrade both database simultaneously
we will need a large down-time which also we can not afford.
Please advise what should we do.
Best Regards

Hello,
Yesterday I met the same problem and very sad about this, however, my story is much more complicated (I think so).
I have 6 databases:
2 - 11g
2 - 10g
2 - 9i
Every database of each release has different characterset(UTF8 and AL16UTF16).
I am trying to create Materialized view with FAST REFRESH on Oracle 11g, when master tables are located on 10g database and 9i database.
Materialized view, which points to 9i database, was successfully created.
Materialized view, which points to 10g database, gets ORA-12028
Like you, I tried many notes from METALINK and thought at the begining that the problem is my characterset. But, when the materialized views were successfully built on Oracle 9i database, I understood that the problem is something else.
Did you find the actual reason why this issue does not work??
Thanks,
Alex

Create Materialized View with GROUP BY

I have a table
treecluster NUMBER(3)
treenumber NUMBER(3)
treedate DATE
nestnumber NUMBER(3)
eggs NUMBER(3)
nestlings NUMBER(3)
fledglings NUMBER(3)
nestfate VARCHAR2(10)
nestfailurecode NUMBER(2)
I want to group the data by treecluster, treenumber, year, and nest number and get a max eggs, nestlings, fledglings. I am doing this with the following:
SELECT treecluster, treenumber, to_char(nestchecksdate, 'YYYY'), nestnumber,
max(eggs), max(nestlings), max(fledglings)
FROM nestchecks
GROUP BY treecluster, treenumber, to_char(nestchecksdate, 'YYYY'), nestnumber;
This works fine.
The last record for a year has a nestfate and nestfailurecode value.
I need to group all information and then also get the nestfate and nestfailurecode for the year. How do I go about getting this information?
I am really trying to create a summary materialized view based on a data table so the select I am trying to craft would be a part of a create materialized view as SELECT...
so I want to be able to group the info and add in the nestfate and failurecode in one step.
Thanks!

try this:
SQL> select * from table_tree;
