A drop materialized view error

I tried to drop two materialized views (I want to drop one and the other as a test to make sure that the behavior was consistent) with SQL Developer today, using the GUI, not the window of SQL command. When I did this, Developer SQL with these MVs among the tables, he tried to run a 'DROP TABLE' rather than a 'DROP MATERIALIZED VIEW' statement and an ugly error message came up with that and of course she didn't. Is this a bug that needs to be addressed? Or maybe that it is already identified and addressed in a future version?

Looks like you're down the underlying table, not the materialized view. If you have a my_mv of materialized view, there is also a table called my_mv.

You must drop the materialized since the Materialized View node in Object Explorer view.

There is a bug, that dropping a materialized view leaves behind a summary that stop the materialized view to be properly cleaned and dropped in the data dictionary.

Connect as sysdba and check DBA_SUMMARIES to an entry of your materialized view. If he doesn't make one: drop summary OWNER. MV_NAME;

That should drop your MV successfully.

Drop Materialized view in peoplesoft

Hello
I have a requirement in which I am refreshing a materialized view.
I created a table, and in my sql, I have a statement
DROP THE PS_FZZZ_PSQ_ACC_MV MATERIALIZED VIEW;
But when I run it I get an error like below
Position of the error: 0 return: 12003 - ORA-12003: materialized view "SYSADM". "" PS_FZZZ_PSQ_ACC_MV ".
There is no SQL failed stmt:DROP MATERIALIZED VIEW PS_FZZZ_PSQ_ACC_MV
30108778 ABENDED to step FZGL_ACCESS process. PRINCIPAL. MV_DROP (SQL) - RC = 12003 (108 524)

Why drop the materialized view to refresh it?

See this doc on the updating of the snapshots:

Refresh of the materialized views - an overview (Doc ID 889342.1)

AFAIK materialized views are supported non-PeopleSoft objects.

Since they are not part of PeopleTools metadata, you can use that specific database through the call objects SQLExec of SQL procedures.

CLARRIFICATION about M - VIEW (Doc ID 987449.1)

You can try to create a step PeopleCode in your AE and run the command

SQLExec ("PS_FZZZ_PSQ_ACC_MV DROP MATERIALIZED VIEW ;");

or create a SQL step and add the drop statement a PLSQL blok

BEGIN

RUN IMMEDIATELY "DROP MATERIALIZED PS_FZZZ_PSQ_ACC_MV VIEW ';

END;

You perform a UNION - a set based operations with a unique genre that prevents him from being eligible to fast refresh. You should be able to do a full refresh, however.

What is the desertion of orderly materialized view with MLOG$.

I have 11.2.4.0 Oracle enterprise edition.
I want to remove completely the MATERIALIZED view and MATERIALIZED view logs.

I need to do this on a production of databases.

It's the right order?
Thank you.

You can drop the materialized view log first, then the materialized views.

Because when you drop a materialized view log is therefore more available to fast refresh, however, it is available to rewrite, so drop materialized view log first, then materialized views. Additional information provided below may help Doc Oracle.

If you delete a simple materialized view that is the least recently refreshed materialized view of a main table, then the database automatically purges the materialized master table see only connect the required lines to refresh the materialized view has fallen.

If you delete a materialized view that was created on a predefined table, then the database removes the materialized view, and table preconstruitse returns to his identity in a table.

When you delete a master table, the database does not automatically drop the materialized views based on the table. However, the database returns an error when it tries to refresh materialized view based on a main table that has been abandoned.

If you delete a materialized view, then all the compiled queries that have been rewritten to use the materialized view will be invalidated and recompiled automatically. If the materialized view was preconstruitse on a table, then the table is not deleted, but it can no longer be maintained by the materialized view refresh mechanism.

Fast refresh materialized view problems
I have two databases (A and B).

In A database, user NICK has a table called COLOUR_MASTER.
Also in this database, NICK issues creating materialized command newspaper view colour_master with the primary key, including the new values (and Yes, there is a primary key defined for this table)
In database B, there is a link of database called A_LINK, connect, Nick, identified by password using 'dbA ';
In database B, user IAN also creates a materialized view CM_MV cool off quickly in select * from colour_master@A_LINK

This statement is done correctly, and there are several million lines in CM_MV when it's done.

Immediately, IAN issued this command:

Start
dbms_mview. Refresh ('CM_MV');
end;

.. .and after a small pause, it gets the error

ORA-12008: error path refresh materialized view
ORA-02068: following sever error of A_LINK
ORA-03113: end of file on communication channel

One more + "select count (*) of colour_master@A_LINK" + subject immediately manages to return the correct number of records in the database so A 3113 is a bit misleading, I think that, in this case have crash, the database remains accessible at all times, there is no network problem (database A and B are both located in the same server so it of not like I'm trying of) connect to halfway around the globe).

The only thing I can think is that there is a permissions issue causes this error. The creation of MV because is made via a link, it is not a problem of IAN see all appropriate, but once the updates come into play, it is perhaps.

Any who can shed light on why I can't do the fast refresh from the view, I can create joyfully, please?
I'm surprised no one asked you to do what is obvious: try to do a select * from colour_master@A_LINK, without that being wrapped in a create materialized MATERIALIZED view. Just do a simple select * from...

My bet is that you will get an error ORA_22992 can not use selected from the remote tables LOB Locators . And if you can't do a simple select * in a remote table, I suspect that you can reasonably expect Fireworks when you try to create or refresh a view materialized on such a thing!

Here's a quick test:

In the 1 database:
=========
```
SQL> create table A (col1 varchar2(2), col2 clob);
Table created.

SQL> alter table A add constraint A1 primary key (col1);
Table altered.

SQL> insert into A values ('AA','This is an entry into a clob column');
1 row created.

SQL> commit;

SQL> create materialized view log on A with primary key including new values;

SQL> create materialized view B refresh fast as

SQL> create materialized view B refresh fast as

SQL> exec dbms_mview.refresh('B');
PL/SQL procedure successfully completed.
```
Which seems to reproduce your problem rather well, I think.

I don't know if there is no work around for this. I mean, obviously you can't miss the CLOB column in your statement of 'create a MV' as I just did, but I don't know if you're still allowed or expected to be able to create a MV on lob columns and that such and such correction will allow you to do. Maybe someone else can provide this information.

But at least you won't have to play Russian roulette with your init.ora parameters!

What is 'Table of container' in materialized views

Hello
What is meant by ' Container Table ' in materialized views?

"Materialized view" (MV) is, in fact, a table, rather than a view.

The term MV is used of the 9i database. In the 7 and 8 databases is the term 'snapshot' (to make things more complicated, the MV concept appeared in the 8i database, but in the context of the data warehouse).

When you create a MV, for example. using the:

Create materialized view emp_mv

full refresh on demand

as select empno, ename from EMP

/

you have, in fact, have created two objects in the data dictionary:

Select object_name, object_type

from user_objects

where object_name = 'EMP_MV. '

order by 1, 2;

OBJECT_NAME OBJECT_TYPE

--------------------- -------------------

MATERIALIZED VIEW EMP_MV

EMP_MV TABLE

You can remove MV and a table of container:

drop materialized view emp_mv;

or you can delete only MV, preserving a table containing:

Let fall the materialized view emp_mv maintain the table;

Kind regards

The Materialized View - ORA-12052: is unable to fast refresh materialized view

Hello
I was hitting my head all day trying to create materialized views. I have made some progress, but have hit a brick wall, unfortunately!
Basically, I have been invited to take a view and see if I can get the benefits of performance by transforming all or part of it in materialized views. Because the underlying tables of the config is updated quite frequently, I want to fast refresh materialized views on commit. However, when I try to create a materialized view containing an outer join in an aggregated materialized view table, I get ORA-12052: is unable to fast refresh materialized view.
I went through the documentation and also Rob van Wijkvery useful series of blogs on the topic (especially http://rwijk.blogspot.co.uk/2009/09/fast-refreshable-materialized-view.html) but have not found anything that matches. Maybe I missed something somewhere along the line, or maybe I'm asking just something completely impossible?

term materialized view for update

Hello
Work on 10g
I created a materialized as fast refresh view on commit.
I need to know how long took for the update.
I tried the below but could not get any results.
SELECT increfreshtim FROM dba_mview_analysis, fullrefreshtim, last_refresh_date, mview_name
Thanks in advance.

It works for me. Post your MView definition and the output of queries, similar to what I posted.

SQL > create table test_table as select level l, col of dbms_random.string ('A', 5) from dual connect by level<=>

SQL > alter table test_table add constraint pk_test_table_l key (l) primary;

SQL > create materialized view test_table; journal

SQL > create a materialized view mv_all_objects cool off quickly in select * from test_table;

Change the definition of the materialized view while maintaining access for users uninteruupted

Hello
We have a system report and the need to change the report definition mv access - like to do it without interruption.
Is this possible?
the sql behind mv was change picks up so column of another table.
Have you heard but not used for dbms_redefinition tables
Thank you

It is built in the Oracle solution for this one, where you can edit the definition WITHOUT interruption. You can drop the materialized view existing with the clause "save table" and rebuilt the view materialized on 'predefined table'. I googled this example for you

create materialized view mv1 as select dept , count(*) as cnt from scott.emp;

We want to change the statement so that only dept more 5 will be calculated
```
drop materialized view mv1 preserve table;
```
Notice that PRESERVE TABLE clause - mv1 table is not droped - single layer mview.
```
desc mv1
```
now, we create the mview with a different query on top of the existing table
```
create materialized view mv1 on prebuilt table as  select dept , count(*) as cnt from scott.emp where dept > 5;
```
Notice that on prebuilt table the mview uses the existing object clause.
```
exec dbms_mview.refresh_mview('mv1');
```
