Help needed in query for Materialized View

Hi,
I want to create a materialized view which has some precalcultaed values.
I have four dimension tables out of which one is a Time Dimension table with levels as Year->Quarter->Month.
The precalculations are the moving averages and cummulative values of Sales Amt on the dimension values over a period of 4 Months.
The dimension tables are Clients, Products, Channel, Time.
Fact Table is Sales_Fact which will have the sales amount for different members of the dimension.
Since my fact table is very huge, i want to create a materialized view where i could store the required calculated measures, here Moving Average of Sales Amt for each Client, Product, Channel dimensions over a period of 4 Months.
Can anybody help with writing the query for this..Any help in this regard will be appreciated..
Please give me suggestions for this..

Need help with SQL Query with Inline View + Group by

Hello Gurus,
I would really appreciate your time and effort regarding this query. I have the following data set.
Reference_No---Check_Number---Check_Date--------Description-------------------------------Invoice_Number----------Invoice_Type---Paid_Amount-----Vendor_Number
1234567----------11223-------------- 7/5/2008----------paid for cleaning----------------------44345563------------------I-----------------*20.00*-------------19

4653456----------11223--------------7/5/2008-----------paid for cleaning------------------------35654765--------------------I---------------------30.00-------------19
Please Ignore '----', added it for clarity
I am trying to write a query to aggregate paid_amount based on Reference_No, Check_Number, Payment_Date, Invoice_Number, Invoice_Type, Vendor_Number and display description with Invoice_type 'I' when there are multiple records with the same Reference_No, Check_Number, Payment_Date, Invoice_Number, Invoice_Type, Vendor_Number. When there are no multiple records I want to display the respective Description.
The query should return the following data set
Reference_No---Check_Number---Check_Date--------Description-------------------------------Invoice_Number----------Invoice_Type---Paid_Amount-----Vendor_Number
1234567----------11223-------------- 7/5/2008----------paid for cleaning----------------------44345563------------------I-----------------*10.00*------------19

4653456----------11223--------------7/5/2008-----------paid for cleaning------------------------35654765-------------------I---------------------30.00--------------19
The following is my query. I am kind of lost.
select B.Description, A.sequence_id,A.check_date, A.check_number, A.invoice_number, A.amount, A.vendor_number
from (
select sequence_id,check_date, check_number, invoice_number, sum(paid_amount) amount, vendor_number
from INVOICE
group by sequence_id,check_date, check_number, invoice_number, vendor_number
) A, INVOICE B
where A.sequence_id = B.sequence_id

Need help writing a query for following scenario

Hi all, I need some help writing a query for the following case:
One Table : My_Table
Row Count: App 5000
Columns of Interest: AA and BB
Scenario: AA contains some names of which BB contains the corresponding ID. Some
names are appearing more than once with different IDs. For example,
AA BB
Dummy 10
Me 20
Me 30
Me 40
You 70
Me 50
Output needed: I need to write a query that will display only all the repeating names with their corresponding IDs excluding all other records.
I would appreciate any input. Thanks

Is it possible to have a records with the same values for AA and BB? Are you interested in these rows or do you only care about rows with the same value of AA and different BB?
With a slight modification of a previous posting you can only select those rows that have distinct values of BB for the same value of AA
WITH t AS (
SELECT 'me' aa, 10 bb FROM dual
UNION ALL
SELECT 'me' aa, 20 bb FROM dual
UNION ALL
SELECT 'you' aa, 30 bb FROM dual
UNION ALL
SELECT 'you' aa, 30 bb FROM dual
SELECT DISTINCT aa, bb
FROM (SELECT aa, bb, COUNT(DISTINCT bb) OVER(PARTITION BY aa) cnt FROM t)
WHERE cnt > 1;

What rights do I need for materialized views scheduling

Hello,
Can anyone tell me what rights do I need to schedule a materialized views at 1:00 am every night?
To create material views I've use the folowing script:
CREATE MATERIALIZED VIEW MV_view
REFRESH COMPLETE
START WITH sysdate NEXT round(SYSDATE + 1) + 1/24
AS SELECT ... join tabeles... ;.
The problem is that on my test server the MV_view run every night, but on production server my materialized views run only once (when I've run the script above).
I have take a look into the user_refresh and in field NEXT_DATE it's the time of my MV_view creation.
It is possible tha my DBA put some restrictions on my schema? Or do I need some rights to use START WITH and NEXT in my script on production server?
Thanks,
XaM

Setting DBMS_METADATA.GET_DDL Output for Materialized Views

Hi all.
My Oracle version is 10g.
I'm extracting the DDL of all the objects from database using the DBMS_METADATA package. I'm using SET_TRANSFORM_PARAM to configure the output because I need a simple sql code, without information about tablespaces, storage and segment attributes. Everything works fine except when I'm working with mviews object types. I can't remove the information about tablespace, storage or segment attributes for materialized views.
I would like to know if there's a related issue about it. Or there's something missing in my code?
I tried to specify the object type as another parameter on DBMS_METADATA.SET_TRANSFORM_PARAM but don't work too.
The only transform parameter that works fine with Materialized Views is the SQLTERMINATOR.
See how I have done:
declare
vDDL clob;
begin
dbms_metadata.set_transform_param (DBMS_METADATA.SESSION_TRANSFORM, 'STORAGE', FALSE);
dbms_metadata.set_transform_param (DBMS_METADATA.SESSION_TRANSFORM, 'TABLESPACE', FALSE);
dbms_metadata.set_transform_param (DBMS_METADATA.SESSION_TRANSFORM, 'SEGMENT_ATTRIBUTES', FALSE);
dbms_metadata.set_transform_param (DBMS_METADATA.SESSION_TRANSFORM, 'SQLTERMINATOR',TRUE);
select dbms_metadata.get_ddl ('MATERIALIZED_VIEW', 'MV_STO020', 'HIS117_CHECK') into vDDL FROM DUAL;
dbms_output.put_line (vDDL);

Right. I found this way but I consider this just a quick fix, because I think there should be a better way to do this.
create table t_clob (c_long);
declare
p clob;
begin
delete from t_clob;
execute immediate 'insert into t_clob (select to_lob(query) from dba_mviews where owner = :1 and mview_name = :2)'
USING 'HIS117', 'MV_STO020';
select 'CREATE MATERIALIZED VIEW MV_STO020' || chr(10) ||
'REFRESH ON DEMAND' || chr(10) || 'AS' || CHR(10) || mv.c_long
into p
from t_clob mv;
dbms_output.put_line(p);
end;
Thanks all.

Select query in materialized view with two dblinks

Hi All,
We have oracle 10g On windows.
We are trying to create materialized view. Scenario is we have base table on other database and we are creating mview on different database.
Basa database have two schema's and i am selecting records from that two schema's using two private db links.
But when i am tryin gto create mview its not getting created. After 15 hrs. its still showing creation command and not finished.
Query is :-
Is it good practice to have two db links in select query of materialized view.

If the former, you ideally want the local Oracle db to send the join to the remote database, and for the remote database to drive the join between those 2 tables. There is a hint (<i>driving_site</i>) that can be used - or the join query can be defined on the remote database as a view, and the local materialised view can then use that remote view.
If you have 2 different db links and joining across these - usually a bad idea to perform distributed database joins. There are lots of limitations as to how the tables can be joined. Worse case, full table scans of both remote tables, pulling all the rows from the 2 remote database tables to the local database, and joining these on the local database.
I have seen some severe performance issues in the past as a result of distributed joins. I'll rather use 2 materialised views for pulling both distributed tables's data locally, and then do the join on local data (using indexes, partition pruning, etc)Hi Billy,
My scenario is i have two database database A and database B. Database A is having two schema's SCOTT AND HR. SCOTT schema have select privileges on HR schema.
DB LINK is between Database B to Database A. name is db.link.B.A.oracle.com.
What if i priovide while creating materialized view, the schema name before the table name in database B for this particuler table so it will pick up the table from that schema using same DB LINK(db.link.B.A.oracle.com.) that i am using to fetch records from SCOTT schema.
Above schnario is like two base schema's and one db link using two schema.

Refresh time for Materialized View

Hi,
I have created a materialized view and set it to refresh everyday at 4 am . When I check the status of the job , it shows the refresh timing between 20 mins to 4 hours . That means , some times it takes 20 mins to refresh , some times 40 , some time 2 hours and some times up to 4 hours. Any reason for the wide range ? Here is the query for the view.

This appears to be a duplicate of Refreshing Materilized view. I replied on the other thread.

SAP query for Material pricing group changes in material.

Dear all,
I'm trying to generate a query for Material Pricing group changes in material. For that I've to retrieve data from follwing three tables MVKE, CDHDR & CDPOS.
Firstly while generating infoset -
I tried it by joining tables MVKE & CDHDR, but system is not allowing it, also table CDPOS can't bejoined.
Then I tried by reading dirctly from table MVKE and then adding additional fields in it. query created using this infoset is giving the output, however it's giving only 1 entry per material entered in input.
for multiple entries in output for MPG changes in same material I tried creating addtional structure for table CDHDR & CDPOS but again I'm getting only 1 entry per material.
please suggest how I can get MPG changes done in specified time period for a material.
Thanks.

Hi
Check the report RSSCD100 and run it for object MAT_FULL for table MVKE. Use this report as a template for your own development.
I hope this helps you
Regards
Eduardo
PD: sorry, the table is DMVKE

Query on Materialized view and materialized view log

I am creating a materialized view something like this.but getting following error:
ERROR at line 1:
ORA-12032: cannot use rowid column from materialized view log on "SCOTT"."EMP"
SQL> create snapshot log on scott.emp;
Materialized view log created.
SQL> create materialized view scott_emp refresh fast on demand as select deptno,sum(sal) sum_sal from scott.emp group by deptno;
ERROR at line 1:
ORA-12032: cannot use rowid column from materialized view log on "SCOTT"."EMP"
Note when i have my query in materialized view as "select * from emp;" in place of
"select deptno,sum(sal) sum_sal from scott.emp group by deptno;" This code works fine.
How do i have a materialized with with a group by clause.
Thanks in Advance

Got the answer myself.
I wasnt adding all the required columns.
CREATE MATERIALIZED VIEW LOG ON scott.emp
WITH SEQUENCE, ROWID (<all the required columns>)
INCLUDING NEW VALUES;
Anyways,
Thanks guys...

Hi Jameer,
This is a hard one, my friend. I understand what you are trying to do.. Try BAPI_DELIVERYPROCESSING_EXEC. It is tricky though.
Moreover you might want to use a FM to fill the IDOC data. something like IDOC_INPUT_**. this might be a better option.
cheers,
Hema.
