Is it possible to create an empty materialized view?
Hi all!I am creating a complex materialized view, but actually the query returns no data.
It seems that it is not accepted by Oracle 10 g, is it true? I've not found anything research literature.
The error I get is 'No more data to read shooting' and the connection to the DB is thus broken.
Maybe you have ideas about the causes of this behavior?
Thank you!

Is Foglight 5.6.2 - possible to create a single user view...
I had a glance through the documentation and am yet to find any specific details on how I can create a foglight user to meet the following criteria: -.
one) can connect to foglight
(b) can view dashboards specific only - aligned specific cartridges
(c) can view the alert details for the points on the scorecards to which access is granted
Basically, we have a few dashboard aligned to a geographic area and the BONE. I need to give access to these dashboards where the person can see only these dashboards. However once they see the dashboard level, if there is an alert shown on this dashboard, the person must be able to view the details of this alert.
I'd appreciate really any guidance you can provide on this one. Thanks in advance for your time.
The problem is related to the discussions around the architecture shared on the community site.
The following requires a clear understanding of how things work within Foglight. It's development work, not something you do casually.
It is possible to create a custom group with roles with access to specific dashboards, with customized any forest docking versions (for example, exploration for alerts), give a specific dashboards allowed the role and then allow specific users are members of a group that has just rights for which enabled the role.
Allowing access to only certain data in the dashboard is more interesting, according to the ease with which data can be separated using queries. For example, how are you going to determine the geographic region for data? If you are lucky enough to be able to distinguish the geographical region, for example, filtering against a hostname with a regular expression, or something similar, then you'll have a chance.
I would like to at least talk to Professional Services about this before trying it yourself. Or, you can wait for multi-tenant happen in a future release of Foglight. He is rumored to be on the road map.

CREATE A CONNECTION MATERIALIZED VIEW / SNAPSHOT LOG
Hello
Is there a difference between create log materialized view on and instant on creat.
Did some research on Google, who discovered: a snapshot log is a related table
the main table of a capture instant and is used for updating snapshots of the Greenbelt master.
The materialized view log is a table associated with the master table of a materialized view. Appear to be the same.
Moreover, import these tables? My database will work normally without the view log.
Kind regards
BecksThere is no difference.
The so-called "Snapshot Logs" pre Oracle8i were called "Materialized View Logs" for Oracle8i.
Search the syntax of SQL to CREATE MATERIALIZED VIEW LOG.

Hi guys, I created a view that obviously gets data from different tables, however (in the future), I will have an additional line in this point of view get data from somewhere, but like the yet that data does not exist, is it possible create a line in a view and paste a random value into it until I have that data available to go back and change. The reason I need this row is that im creating a report and I would like to bring in the column with some random txt inside then once data are available simply change the view which will save me having to change the report if you get my drift?
Any help would be greatly appreciated.786733 wrote:

I think you want to add a column to the display (as the header suggests) and not an additional line. A row of addition would change for all reports. However, an additional column should be considered in a report which is to rely on this point of view.
You can add additional columns to all select statements. And your opinion is nothing else than a stored select statement.

/* Base select */ select * from dual; DUMMY ----- X /* Add a string null column colA */ select d.*, '' as colA from dual d; DUMMY COLA ----- ---------- X /* Add a number column colA */ select d.*, cast(null as number) as colA from dual d; DUMMY COLA ----- ---------- X /* Add a string column colA with random values*/ select d.*, dbms_random.string('A', 10) as colA from dual d; DUMMY COLA ----- ---------- X QvKJWWdbTw -

So pls advice me no alternative.
Querys trigger:

Hello
I learned and referred website as much as we can not able to create a trigger in MView (sorry we create trigger but none use of creation because in view no insert and update happened). So I drop completely the materialized view concepts and relaxation.
Instead of, I have using the procedure to insert records in a table and then I created one by dbms_scheduler job.
This discussion will be useful for any future reference.
-procedure-
create or replace procedure p2
as
Start
INSERT / * + APPEND * / INTO FSG1_FUND000 SELECT * FROM FSG1_FUND000@remote;

Creating a discount on commit Materialized view
Hello
I am trying to create a refresh materialized view validation so that whenever I run followed by DML commit on Master he table should get quickly reflect in my view materialized.
I gave SELECT on table privilege to the user where this point of view will be created
The master:
GRANT SELECT ON HR. EMPLOYEES AT SCOTT.
Scott:
Scott.hremp CREATE MATERIALIZED VIEW
COOL OFF QUICKLY ON COMMIT
AS
SELECT * FROM HR. EMPLOYEES;
ERROR on line 4:
ORA-01031: insufficient privileges
Then I Grant all on the table EMPLOYEES at SCOTT.
GRANT ALL ON hr. EMPLOYEES AT SCOTT;
Then got following error when creating view materilized:
SQL > CREATE MATERIALIZED VIEW scott.hremp

4. SELECT * HR. EMPLOYEES;
SELECT * FROM HR. EMPLOYEES
*
ERROR on line 4:

Kindly guide me.
Also, I want to know why I needed to GRANT ALL HR for the creation of this point of view, materialized.
You also need a (selection) grant on the MV newspaper created for master during an attempt to build a quickly updatable MV.

Would not you other placed in front of the game that you are now (unless you can ETG and specify the index of the Organization, which I think is not the case).
You know the query and the types of data required for the materialized view, you try to create it now. You know you want it impose a primary key constraint.
Take this knowledge and create the table you normally create a table (columns, constraints, etc...) as I showed in my example. And then post your order to create materialized view as you now except use the syntax I have demonstrated to make use of the existing index organized table.

Materialized view appeared in SELECT * FROM DEPT; So, it must take all the data that are available in the Dept table each time it is regenerated.
What you intend to do is force the MView to choose the data "Modified" of table DEPT. Is not possible, unless you have some distinctive sign that the MView should be checked.
For Eg :-(just an idea that I did not test this)
Adding another column to identify records updated the: -.
alter table dept add is_modified varchar2(1) default 'N';MView create instruction me altered as
select * from dept where is_modified = 'Y';Write a trigger that sets the column IS_MODIFIED 'Y', each time that a record is inserted or updated. Don't worry about the deleted records (if this isn't a Soft Delete) as MView does not see records that are not present in the master table.
You simply need to ensure that, whenever the MView is refreshed, the IS_MODIFIED the Department table must be set to 'n', so that it does not display a false positives.

I explored a similar approach, using the following test case.
It creates a table "MASTER_TABLE" containing 20,000 lines and a CLOB containing an XML fragment like this:

Hi all. I get this error when you try to create a materialized view. I have several other MV I've created without problem, but I can not find the catch here, can anyone help?. I can't find the duplicates. The only double I was although entered in the function Pipeline_Code and the column being called a column.

Questions on the tables of materialized views and MV newspaper
Hi all
Have some questions about Materialized View.
(1) once the materialized view reads the records from the table MLOG, reviews the MLOG get purged. fix? or is that not the case? In some cases, I see still (old) records in the MLOG table even after updating MV.
(2) how the table MLOG distinguishes between a reading which comes from a MV and a reading that comes from a user? If I execute manually
"Select * < table MLOG > ' could get record of the table MLOG redacted all the same way as it does after a refresh of MV?
(3) one of our MV updates crashes intermittently. Based on the events of waiting I noticed that it was a 'db file sequential read' against the main table. Finally I had to put an end to the update. I don't know why it was sequential reading on the main table when she should be reading the table MLOG. Any ideas?
(4) I saw 'file db scattered read' (full table scan) usually on tables, but I was surprised to see 'db file sequential read' against the table. I thought sequential read occurs normally against the index. All the world has noticed this behavior?
Thanks for your time.(1) once all the registered materialized views have read a particular line in a trunk of materialized view, it is removed, Yes. If there are multiple materialized views that are based on the same newspaper, they would all need to refresh before it would be safe to delete the log entry for MV. If one of the materialized views is no incremental updating, there may be cases where the log purge automatically.
(2) No, your query does not cause anything be served (although you wouldn't see something interesting unless you get to implement a lot of code to analyze change vectors stored in the journal). I don't know the exact mechanism used by Oracle has been published, if you could go through and draw a session to get an idea of the moving parts. From a practical point of view, you just need to know that when you create an updatable materialized view fast, it will register as interested especially newspapers MV.
(3) it depends on what is stored in the log of MV. The update process may need to recover specific table columns if your log stores just the fact that the data for a particular key changed. You can specify when you create a materialized view that you want to store specific columns or include the new clause values (with the NEW VALUES INCLUDING). It is perhaps beneficial (or necessary) for the refreshment quick process, but it would tend to increase the storage space for the materialized view log and increase the cost of the maintianing the materialized view log.
(4) sequential reads on a table are perfectly normal - it just means that someone looking for a block of data in the table (i.e. looking a line in the table of ROWID based on the ROWID in an index or a materialized view log).

Existing record of materialized views
There that (the name of mv) typo?
from: http://download.oracle.com/docs/cd/E11882_01/server.112/e10810/basicmv.htm#i1008170
The following example illustrates the two steps required to save a user-defined table. First of all, the table is created, then the materialized view is defined using exactly the same name as the table . This materialized view sum_sales_tab_mv is eligible to be used in the query rewriting.
CREATE TABLE sum_sales_tab
PCTFREE 0 TABLESPACE demo
STORAGE (INITIAL 8M) AS
SELECT s.prod_id, SUM (amount_sold) AS dollar_sales,
Sum (QUANTITY_SOLD) AS unit_sales
S SALES GROUP BY s.prod_id;
CREATE MATERIALIZED VIEW sum_sales_tab_mv
ON PREBUILT WITHOUT REDUCED ACCURACY TABLE
ENABLES QUERY REWRITE
SELECT s.prod_id, SUM (amount_sold) AS dollar_sales,
Sum (QUANTITY_SOLD) AS unit_sales
S SALES GROUP BY s.prod_id;
How is this exactly the same name ? I don't see how the mv creation involves even the existing table.There that (the name of mv) typo?
Looks like that it:
SQL> create table sales 2 (prod_id number 3 ,amount_sold number 4 ,quantity_sold number); Table created. SQL> CREATE TABLE sum_sales_tab 2 PCTFREE 0 --TABLESPACE demo 3 STORAGE (INITIAL 8M) AS 4 SELECT s.prod_id, SUM(amount_sold) AS dollar_sales, 5 SUM(quantity_sold) AS unit_sales 6 FROM sales s GROUP BY s.prod_id; Table created. SQL> CREATE MATERIALIZED VIEW sum_sales_tab_mv 2 ON PREBUILT TABLE WITHOUT REDUCED PRECISION 3 ENABLE QUERY REWRITE AS 4 SELECT s.prod_id, SUM(amount_sold) AS dollar_sales, 5 SUM(quantity_sold) AS unit_sales 6 FROM sales s GROUP BY s.prod_id; CREATE MATERIALIZED VIEW sum_sales_tab_mv * ERROR at line 1: ORA-12059: prebuilt table "EDW"."SUM_SALES_TAB_MV" does not exist SQL> CREATE MATERIALIZED VIEW sum_sales_tab 2 ON PREBUILT TABLE WITHOUT REDUCED PRECISION 3 ENABLE QUERY REWRITE AS 4 SELECT s.prod_id, SUM(amount_sold) AS dollar_sales, 5 SUM(quantity_sold) AS unit_sales 6 FROM sales s GROUP BY s.prod_id; Materialized view created. -
