Materialized view, problem in selecting a particular field

Hi,
can anyone please help me with this issue.
I have table which contains data for 3 different years. It usually contains data for the current year, the next year and the previous year i.e the calender current year.
YEAR TL JN Q
2006 1 1 30
2007 1 1 6
2008 1 1 4
2006 1 2 5
2008 1 2 4
This is how my table looks like. For this table i have created a view which looks like this
TL JN Q1 Q2 Q3
1 1 30 6 4
1 2 5 50
The view is a summary for the table.
The problem now is that the Master table on which the view is based keeps getting updated. In some cases it may so happen that the table can contain data for a year other than the calender current year, previous year and next year.
In this case how do i identify the year to create the view.
For example the table can get populated with records for the year 1999, in this case how can i identify the year .
This is the code i have written to create the view
create view vw_summary(TL,JN,Q1,Q2,Q3)
AS SELECT TL.,JN,
MAX(DECODE(YEAR,TO_CHAR(SYSDATE,'YYYY'),Q,NULL)Q1,
MAX(DECODE(YEAR,TO_CHAR(SYSDATE,'YYYY')-1,Q,NULL))Q2,
MAX(DECODE(YEAR,TO_CHAR(SYSDATE,'YYYY')+1,Q,NULL))Q3
FROM TABLE GROUP BY TL,JY
CAN ANYONE PLEASE HELP ME.?
I am creating a materialized view for the table

one more opint to be added is that inside this procedure, i am checking for athe value of column "FLAG" in an other table param. if this flag is set to Y then i wil populate the table(on which the view is based) according to the parameter passed to the procedure. But if the flag value in the table params is set to N then i am suppose to check an other column called ACHYR in the table params. This column holds a year value say 1999.
In this case the procedure should populate the table with the records for the year 1999.
But how do I check this parameter in the view?

Problem encountered when join two remote tables in a materialized view

I'm using oracle 9.2.0.6
1> I have two tables:
CREATE TABLE TEST
A VARCHAR2(100 BYTE),
C DATE
CREATE TABLE TEST1
A VARCHAR2(100 BYTE),
B TIMESTAMP
2>. I defined a prebuild table:
CREATE TABLE MV_TEST1
ID1 ROWID,
A VARCHAR2(100 BYTE),
ID2 ROWID,
B TIMESTAMP(6),
C DATE
3> I created mview logs:
CREATE MATERIALIZED VIEW LOG ON PSI_TEST.TEST
WITH ROWID
INCLUDING NEW VALUES;
CREATE MATERIALIZED VIEW LOG ON PSI_TEST.TEST1
WITH ROWID
INCLUDING NEW VALUES;
4> when I create mview:
CREATE MATERIALIZED VIEW PSI_TEST.MV_TEST1
ON PREBUILT TABLE WITH REDUCED PRECISION
REFRESH FAST ON DEMAND
WITH PRIMARY KEY
AS
select
test.rowid id1,
test.a,
test1.rowid id2,
test1.b,
cast(null as date) c
from test , test1
where test.a = test1.a(+);
It is created successfully.
5> problem:
when I use remote tables to do the same thing, say test and test1 are in another instance and are connected by a dbLink, I couldn't create the mview successfully:
CREATE MATERIALIZED VIEW PSI_TEST.MV_TEST1
ON PREBUILT TABLE WITH REDUCED PRECISION
REFRESH FAST ON DEMAND
WITH PRIMARY KEY
AS
select
a.rowid id1,
a.a,
b.rowid id2,
b.b,
cast(null as date) c
from test@dbl a, test1@dbl b
where a.a = b.a(+);
when run above statement, I got:
ORA-12015: cannot create a fast refresh materialized view from a complex query
Any ideas? Or joining two table through a dblink for a mview is not allowed at all?
Thanks in advance.

No one has a clue?

Problem when try to get the next refresh date of a materialized view

I have a materialized view set to auto refresh(e.g hourly), I need to query this date and display in the report. I create a procedure which return the NEXT_DATE from the ALL_REFRESH_CHILDREN table, the procedure and the view all in schema HK3XDDB.
If I login as sys, dba in the sql plus and query the procedure, it return the next date, but if I login as normal user which has permission to execute all procedures, it didn't return anything, so I change ALL_REFRESH_CHILDREN to USER_REFRESH_CHILDREN, still no luck. But the details from the USER_MVIEWS can be returned, just won't return anything in the REFRESH one. How to query the next date out?
Another strange thing is, if I login as sys dba, it return the next date, but if I use a select next_date into statement in the procedure it will throw a data not found error.
I stuck here for several hours just can't figure it out, any suggestions are welcome,
Cheers

Thank you for the reply. It's same with USER_REFRESH_CHILDREN, I can get the result when I run the procedure in SQL PLUS login as sys dba, but if I run the procedure using normal user which has permission to run any procedure, then nothing return. It might be a permission problem but I just can't figure out why.
Let me explain in detailed:
Schema HKXDDB, this schema has procedure TestProcedure, in the procedure, I have two ref cursor return, one is for select * from USER_JOBs (or from USER_REFRESH_CHILDREN, I have tried both), one is for select * From USER_MVIEWS, this schema has the materialized view. User HKDWUser has permission to run any procedures, so when this user run the TestProcedure which is own by HKXDDB, the cursor that select from USER_MVIEWS can return results which are materialized views owned by HKXDDB, but the cursor that select form USER_JOBS or USER_REFRESH_CHILDREN always return no rows.
Any permission I need to assign to HKDWUSER to get the jobs or fresh group that owned by HKXDDB?
Cheers

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
Madhup

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

A problem with a Materialized View

Hi,
I have a ordinary table with a three column compound primary key (COL_Id, COL_ValidFrom, COL_CaseId)
I also have a MV that selects from that table. This one compiles just fine. It looks like this:
CREATE MATERIALIZED VIEW "MV_02"
REFRESH FORCE ON COMMIT
AS SELECT COL_Id, COL_ValidFrom, MAX(COL_CaseId) CaseId FROM TBL_MediaText GROUP BY COL_Id, COL_ValidFrom;
Works fine. Now I'm trying to create a second MV that selects from the first MV. It looks like this:
CREATE MATERIALIZED VIEW "MV_03"
REFRESH FORCE ON COMMIT
AS
SELECT a.COL_Id, a.CaseId, a.COL_ValidFrom, NVL(MIN(b.COL_ValidFrom)-1, TO_DATE('2099-12-31','yyyy-mm-dd')) ValidTo
FROM MV_02 a, MV_02 b
WHERE a.COL_Id=b.COL_Id(+) AND a.COL_ValidFrom < b.COL_ValidFrom(+)
GROUP BY a.COL_Id, a.CaseId, a.COL_ValidFrom;
This one does not parse. (ORA-12054) There seem to be a probelem with the ON COMMIT command. I have searched the web and found some info on the subject. It tells me to create a MV log, wich I have. I've also tried to put count(*) and count(b.COL_validfrom). But it just wont work.
I see a possibilty of yhe problem laying in te fact that I join using two parts of my PK. Also there might be a problem with the fact that i can't create a log for MV_02 WITH PRIMARY KEY. Or maybe you can't have a MV selecting from another MV?
Do anyone know how i should specify my Logs and/or querys in order for this to parse?
I'm using 10.1, and I do have the ON REFRESH COMMIT-privilege.
Thanks!

Problem in materialized view

Hello everybody!!!
I used the following script in order to see the automatic refresh of data contained in a materialized view.
I used the following script in SCOTT schema:
create materialized view log on emp
with rowid (job,sal)
including new values
create materialized view emp_mv
build immediate
refresh fast on commit
as
select job , sum(sal) sum_sal
from emp
group by job
The problem is that after i update the sal column (and commit it) of an employee and selecting from the emp_nv , I DO NOT see any difference , although the materialized view log has been updated successfully!!!
Under which circumstances the materialized view would be updated as well?
Simon.

What is job_queue_processes set to on your system? Materialized view refreshes are generally done as background jobs, so that initializiation parameter needs to be set to a non-zero value.

Synonym problem with external table in materialized view

I have a materialized view that includes selects on two external tables.
However, no matter how I try to access the external tables, the creation fails with a "Synonym Translation Is No Longer Valid" (ORA-00980) error.
This happens even when I replace the tablename with the full table name, including the link.
I can create a view just fine, but if I then try something like CREATE MATERIALIZED VIEW mvw_my_view AS SELECT * FROM vw_my_view (where vw_my_view is the view in question), it still throws the Synonym Translation exception.

00980, 00000, "synonym translation is no longer valid"
// *Cause: A synonym did not translate to a legal target object. This
//         could happen for one of the following reasons:
//         1. The target schema does not exist.
//         2. The target object does not exist.
//         3. The synonym specifies an incorrect database link.
//         4. The synonym is not versioned but specifies a versioned
//            target object.
// *Action: Change the synonym definition so that the synonym points at
//          a legal target object.It is really, Really, REALLY difficult to fix a problem that can not be seen.
use COPY & PASTE so we can see what you do & how Oracle responds.

Problem with Materialized Views in 10g

Hi All,
I am creating a Materialized View like
CREATE MATERIALIZED VIEW mvname TABLESPACE SYSTEM BUILD IMMEDIATE REFRESH WITH ROWID FOR UPDATE AS ( SELECT a,b,c FROM table_a,table_b,table_c WHERE cond );
I am getting an error
SQL Error: ORA-12013: updatable materialized views must be simple enough to do fast refresh.
Can anyone tell what is the problem?
I have included rowid of all three tables in select clause.

Hi,
From Oracle Docs:
ORA-12013: updatable materialized views must be simple enough to do fast refresh
Cause: The updatable materialized view query contained a join, subquery, union, connect by, order by, or group by caluse.
Action: Make the materialized view simpler. If a join is really needed, make multiple simple materialized views then put a view on top of them.

the refresh failed without error. only 'NEEDS_COMPILE' value in COMPILE_STATE !!
If i try an 'alter compile' it's OK
If i try an execute DBMS_snapshot.refresh('MV_00087_BRANCARD', '?') it's ok
...but the refresh is not automatic ;((
any idea about this strange behavior ?
thanks for your help.

Any DDL or DML operation on base table can invalidate a materialized view
State of materialized views can be checked in dictionary view USER_MVIEWS or ALL_MVIEWS. and column- STALENESS
You can use
ALTER MATERIALIZED VIEW MV_Name COMPILE statement to validate the materialized view and get the correct state.
Thanks

Materialized view refresh problem

Hi,
I have a materialized view which refreshes every 12 hour. Very often (not always) the refresh fails with the following error in the alert log.
What could be the reason behind this and how to rectify this?

Important error descriptions are as follows. Follow actions here.
ORA-12008 error in materialized view refresh path
Cause: Table SNAP$_mview_name reads rows from the view MVIEW$_mview_name, which is a view on the master table (the master may be at a remote site). Any error in this path will cause this error at refresh time. For fast refreshes, the table master_owner.MLOG$_master is also referenced.
Action: Examine the other messages on the stack to find the problem. See if the objects SNAP$_mview_name, MVIEW$_mview_name, mowner.master@dblink, mowner.MLOG$_master@dblink still exist.
ORA-08103 object no longer exists
Cause: The object has been deleted by another user since the operation began.
Action: Remove references to the object.

Problem with replication based on materialized view

Problem with replication based on materialized view...
Given:
1. Source: S-1
2. Targets: T-1, T-2
3. DB links: from T-1 to S-1, from T-2 to S-1
Required replicate table TBL on S-1 to T-1, T-2 via db links.
On S-1 was created materialized view log with PK on TBL. On T-1, T-2 were created mat.views as "on prebuilt table refresh fast on demand". In case of get "ORA-12034: materialized view log younger than last refresh" or initial load - perform complete refresh. Initial load on T-1 takes about 1 hour, on T-2 - about 12 hours. Refresh is executed via job with minutely interval. If refresh is running then it is not performed.
Problem: after initial load on T-1 performs fast refresh, but on T-2 raised ORA-12034 and complete performs again.
What's wrong?

34MCA2K2, Google lover?
I confess perhaps I gave a little info.
View log was created before MV.
It was the first initial load.
No refresh failed.
No DDL.
No purge log.
Not warehouse.
There is no such behavior for MVs on another sites.
P.S. I ask help someone who knows what's wrong or who faced with it or can me follow by usefull link.
P.P.S. It's a pity that there is no button "Useless answer"
