Invalid Materialized view Oracle 8

Hi,
I have a problem with a Invalid materialized view in Oracle 8.
this view is in a .sql file. When the SQL file runs and the view is invalid the the loading is stopped.
Does anyone know if it's possible in Oracle 10 that Oracle solves the problem (with the view) it self, or that I have to repair it myself and run the file again?
thanks for the help
kinds regards,
Richard van der Haag

Richard,
There is nothing that on MV gets done automatically in 10g. Please post your query and we will see where the error is.
Thanks

Invalid materialized view at system schema

My database version is 11.2.0.2.0.
I have found more than 100 invalid materialized views at system schema. These materialized views are named as MV$$_0BCC00%.
I did not find any documents on why these views are created. Can anyone help me about the issue?

Hi;
As Forstmann mention some of MV comes by default installation, you need to check by upper query to see defining of those MV..
FOr mV related error issues you can also see:

Invalid Materialized view

Hi ALL:
some of MVs become invalid (yes, we did app upgrade over the weekend). I looked on every object reference in the MV, all permissions - can't find anything.
I dropped MVs and created them no errors. Status changed to VALID. I decided to re-COMPILE them (because I saw public synonyms for MVs as INVALID). After compilation status changed back to INVALID.
Oracle 11.2, Solaris 10
Any ideas where to look?
Thanks,
Greg

Your materialized view will be marked INVALID as soon as any DML is done against the tables on which it is based. Not a problem.

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.

Materialized view showing red cross in front of it in SQL developer

we created a materialized view in oracle database,it works fine, and other views that select on it return results and work fine too. But it has a red cross in front of it in oracle developer.
I then refresh the view, or recreate the view, it shows green, but after a while when I come back, the red cross show up again.
What does it mean, any error message we can find?
Thanks

It means your system is working NORMALLY! There is no 'error message' to find because there is no error. What you describe is EXACTLY how MVs are designed to work.
It is NORMAL for MVs to be, and to become, invalid, especially if there refresh setting is ON DEMAND. Don't confuse 'validity' with 'staleness'; they are very different things.
See the section 'Invalidating Materialized Views' in the Data Warehousing Guide'
http://docs.oracle.com/cd/B28359_01/server.111/b28313/advmv.htm#i1007082
Invalidating Materialized Views
Dependencies related to materialized views are automatically maintained to ensure correct operation. When a materialized view is created, the materialized view depends on the detail tables referenced in its definition. Any DML operation, such as an INSERT, or DELETE, UPDATE, or DDL operation on any dependency in the materialized view will cause it to become invalid. To revalidate a materialized view, use the ALTER MATERIALIZED VIEW COMPILE statement.
A materialized view is automatically revalidated when it is referenced. In many cases, the materialized view will be successfully and transparently revalidated. However, if a column has been dropped in a table referenced by a materialized view or the owner of the materialized view did not have one of the query rewrite privileges and that privilege has now been granted to the owner, you should use the following statement to revalidate the materialized view:
ALTER MATERIALIZED VIEW mview_name COMPILE;
The state of a materialized view can be checked by querying the data dictionary views USER_MVIEWS or ALL_MVIEWS. The column STALENESS will show one of the values FRESH, STALE, UNUSABLE, UNKNOWN, UNDEFINED, or NEEDS_COMPILE to indicate whether the materialized view can be used. The state is maintained automatically. However, if the staleness of a materialized view is marked as NEEDS_COMPILE, you could issue an ALTER MATERIALIZED VIEW ... COMPILE statement to validate the materialized view and get the correct staleness state. If the state of a materialized view is UNUSABLE, you must perform a complete refresh to bring the materialized view back to the FRESH state. If the materialized view is based on a prebuilt table that you never refresh, you will need to drop and re-create the materialized view.
As the doc states Oracle will normally 'revalidate' an MV when it is referenced. You can do this manually by using 'ALTER . . . COMPILE'. For an ON DEMAND MV compiling it will NOT alter the contents of the MV - it may stil be STALE.
You don't need to REFRESH or recreate the MV to make it valid; just recompile it. If it doesn't become VALID after you compile it then there is usually an issue with one of the dependent objects that you need to resolve.

Materialized view with tables in different schemas

Hello,
I want to create a materialized view with a table from a different schema in the SELECT statement. For materialized view I would like to apply the "REFRESH COMPLETE ON COMMIT" option.
Here the code:
CREATE MATERIALIZED VIEW S1.MV_EXAMPLE
TABLESPACE TS1
PCTFREE 0
BUILD IMMEDIATE
REFRESH COMPLETE ON COMMIT
AS
SELECT T.COLUMN1 COLUMN
FROM S2.TABLE1 T
I can't execute this SQL because I get an "insufficient privileges" error to this table:
FROM S2.TABLE1 T
FEHLER in Zeile 9:
ORA-01031: Insufficient privileges
User S1 has the following privileges:
CREATE SESSION
CREATE SNAPSHOT
CREATE TABLE
CREATE QUERY REWRITE
SELECT ANY TABLE
User S2 has the following privileges:
CREATE SESSION
CREATE SNAPSHOT
CREATE TABLE
CREATE QUERY REWRITE
ALTER ANY SNAPSHOT
Which privileges are missing?
Thanks, Mathias

Thanks Kamal for your answer!
S1 has the grant select directly. But I solveld the problem. The system privilege "ON COMMIT REFRESH" was missing for S1. This has to be set if any of the tables are outside the owner's schema of the materialized view (ORACLE documentation - Data Warehouse Guide).
But one thing is not clear to me yet and the ORACLE documentation doesn't give me an answer. I can set the refresh-attribute ON COMMIT on a materialized view containing only joins when a group by clause is set. If the group by clause is missing I can't! Why?
Regards, Mathias

Regarding Materialized view

Hi all,
I have two database .there is one table in first database.I want to synchronize this table with second database. for that i have created materialized view but when i am create that materialized view it gives following error
ORA-12054: cannot set the ON COMMIT refresh attribute for the materialized view
I m access table from first table to second database by database link.
How can resolve this error? Kindly give suggestion.
Thanks in advance.

From the document.
Refresh Materialized Views
Oracle maintains the data in materialized views by refreshing them after changes are made to their master tables. The refresh method can be incremental (fast refresh) or complete. For materialized views that use the fast refresh method, a materialized view log or direct loader log keeps a record of changes to the master tables.
Materialized views can be refreshed either on demand or at regular time intervals. Alternatively, materialized views in the same database as their master tables can be refreshed whenever a transaction commits its changes to the master tables.

Result of materialized views

Hi,
I have created a materialized view, making a complete refresh ervery day at 1am.
It's possible that a query on this mview at refresh time will be empty will the query execute before and after the refresh wont be empty.
(The refresh will take about 60 Minutes to complete.)
Thanks.
regards,
Rainers

When you do a complete refresh a materialized view, Oracle deletes the old data and inserts the new data in a single transaction. Queries will never see the materialized view as empty-- the will see the old data until the refresh finishes, at which point they will see the new data.

Invalid Column Name on select from materialized view?

Hey all, I have created this materialized view for my java to select from. For some reason when I try to select from it, I get invalid column name. Here is my mat view statement in its simplest form:
create materialized view mv_pgridtcevcluster_property as
select distinct clustername_ as "OBJECT_ID", CLUSTERNAME_, LICENSEMODE_
from p_gridtcevcluster p
order by clustername_;
Now when I run my select statement from jdbc:

java.sql.SQLException: Invalid column name
     at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112)

Anyone have issues with this before? It seems to throw the error sporatically, any help would be much appreciated!

Edited by: TimS on Mar 30, 2009 1:54 PM
Nevermind, figured it out. Was using wrong column name identifier when picking values from resultset.

Since you have "OBJECT_ID" in quotes, Oracle stores the column name literally and case sensitively, and the column name must be capitalized when referenced.
From a regular sql*plus window, try
select object_id from mv_pgridtcevcluster_property;
select OBJECT_ID from mv_pgridtcevcluster_property;
select "OBJECT_ID" from mv_pgridtcevcluster_property;What is the result from each of them?

Creating a Materialized View in Oracle 8i

Hello -
What are the steps and privileges required to create a materialized view in Oracle 8i?
Thanks

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.

How to view SQL for a materialized view in SQL Developer (Oracle 11g R2)

Good Morning,
I am new to SQL Developer 3.1.07 and just installed it on a Windows 7 PC yesterday.
There's a materialized view for which I need to view (and eventually update) the SQL. The mat'lized view is in another schema, but my Oracle user does have access to the schema and to this particular mat'lized view. My user also has SELECT, INSERT, UPDATE, DELETE, DEBUG, and ALTER permissions. When I select (click on) the matl'ized view in the object tree on the left, a multi-tab window opens with information in the Columns, Indexes, Grants, Dependencies and Details tabs, but the SQL pane is blank. I don't know if there's some other GRANT that I need in Oracle, or if there's something else I need to do in SQL Developer to see the matl'ized view SQL.
Thanks

I'm not sure what privileges you might need besides the one you listed except RESOURCE on the MV, or maybe CREATE ANY MATERIALIZED VIEW.
Can you use DBMS_METADATA.GET_DDL to get the data you want (may/may not work due to privileges)?

Materialized view in Oracle 9i/10g SE?

Hi All,
Can we define MV's in standard edition of oracle9i & 10g database? If yes, are there any limitations on creation of MV's in Standard edition compare to Enterprise edition like Query rewrite, creation of log tables etc?
As per link : http://www.dba-oracle.com/art_so_oracle_standard_enterprise_edition.htm , MV's seems to be avialable in EE.
Also let me know if there is any document available to general public for comparision of various edition features of oracle database version.
Thanks in advance,
AJ

As far as I'm aware, you can create MV in standard and also there is no limitation that I'm aware off
Standard and Enterprise Edition
A. Basic replication (MV replication)
\- transaction based
- row-level
- asynchronous from master table to MV (Materialized View)
- DML replication only
- database 7 / 8.0 / 8i / 9i / 10g
Variants:
1. Read-only MV replication
2. Updateable MV replication:
2.1 asynchronous from MV to master
2.2 synchronous from MV to master
3. Writeable MV replication
Enterprise Edition only
B. Multimaster replication
\- transaction based
- row-level or procedural
- asynchronous or synchronous
- DML and DDL replication
- database 7 / 8.0 / 8i / 9i / 10g
- Enterprise Edition only
Variants:
1. row-level asynchronous replication
2. row-level synchronous replication
3. procedural asynchronous replication
4. procedural synchronous replication
C. Streams replication
(Standard Edition 10g can execute Apply process)
\- (redo) log based
- row-level
- asynchronous
- DML and DDL replication
- database 9i / 10g (10g has Down Streams Capture)

What's the impact of rowid materialized view in oracle 10g

Hello to all ;
Oracle official docs saying
ROWID materialized views should be used only for materialized views based on master tables from an Oracle7 database, and should not be used from Oracle8 or higher.
For 10g or higher versions can we consider rowid materizlized view ?
product 10.2.0.4 and 11g r2 on Redhat 5.1

No
should not be used from Oracle8 or higher10g is higher
