Inserting into a base table of a materialized view takes lot of time.......

Dear All,
I have created a materialized view which refreshes on commit.materialized view is enabled query rewrite.I have created a materialized view log on the base table also While inserting into the base table it takes lot of time................Can u please tell me why?

Dear Rahul,
Here is my materialized view..........
create materialized view mv_test on prebuilt table refresh force on commit
enable query rewrite as
SELECT P.PID,
SUM(HH_REGD) AS HH_REGD,
SUM(INPRO_WORKS) AS INPRO_WORKS,
SUM(COMP_WORKS) AS COMP_WORKS,
SUM(SKILL_WAGE) AS SKILL_WAGE,
SUM(UN_SKILL_WAGE) AS UN_SKILL_WAGE,
SUM(WAGE_ADVANCE) AS WAGE_ADVANCE,
SUM(MAT_AMT) AS MAT_AMT,
SUM(DAYS) AS DAYS,
P.INYYYYMM,P.FIN_YEAR
FROM PROG_MONTHLY P
WHERE SUBSTR(PID,5,2)<>'PP'
GROUP BY PID,P.INYYYYMM,P.FIN_YEAR;
Please help me if query enable rewrite does any performance degradation......
Thanks & Regards

How to insert into two differents tables at the same time

Hi
I'm newer using JDev, (version 3.1.1.2 cause the OAS seems to support just the JSP 1.0)
and I want to insert into two differents tables at the same time using one view.
How can I do that ?
TIA
Edgar

Oracle 8i supports 'INSTEAD OF' triggers on object views so you could use a process similar to the following:
1. Create an object view that joins your two tables. 'CREATE OR REPLACE VIEW test AS SELECT d.deptno, d.deptname, e.empname FROM DEPT d, EMP E'.
2. Create an INSTEAD OF trigger on the view.
3. Put code in the trigger that looks at the :NEW values being processed and determines which columns should be used to INSERT or UPDATE for each table. Crude pseudo-code might be:
IF :NEW.deptno NOT IN (SELECT deptno FROM DEPT) THEN
INSERT INTO dept VALUES(:NEW.deptno, :NEW.deptname);
INSERT INTO emp VALUES (:NEW.deptno, :NEW.empname);
ELSE
IF :NEW.deptname IS NOT NULL THEN
UPDATE dept SET deptname = :NEW.deptname
WHERE deptno = :NEW.deptno;
END IF;
IF :NEW.empname IS NOT NULL THEN
UPDATE emp SET empname = :NEW.empname
WHERE deptno = :NEW.deptno;
Try something along those lines.

Multi-table mapping is not inserting into the primary table first.

I have an inheritance mapping where the children are mapped to the parent table oids with the "Multi-Table Info" tab.
One of children is not inserting properly. Its insert is attempting to insert into one of the tables from the "Additional Tables" of "Multi-Table Info" instead of the primary table that it is mapped to.
The other children insert correctly. This child is not much different from those.
I looked through the forums, but found nothing similiar.

I would expect the Children to be inserted into both the primary table and the Additional Table? Is the object in question inserted into the primary table at all? Is the problem that it is being inserted into the Additional Table first? If it is, are the primary key names different? Is it a foreign key relationship?
If the object in question has no fields in the additional table is it mapped to the additional table? (it should not be)
Perhaps providing the deployment XML will help determine the problem,

Nologging direct-path insert into an indexed table

Hello,
Does anyone have an idea how I can suppress generation of undo logs for direct-path insert into an indexed table on 11.2.0.1.0:
CREATE TABLE TBL(ID NUMBER) NOLOGGING;
CREATE INDEX IDX ON TBL(ID) NOLOGGING;
INSERT /*+ APPEND */ INTO TBL SELECT /*+ APPEND */ ROWNUM FROM ...; -- Source table has 400,000,000+ rows

XSQL Insert into Schema based Table

Hi,
I am struggling with this one:
My test XML is well formed:
<?xml version="1.0"?>
<SC_ESP>
<ResultSet>
<ApplicationID>App0001</ApplicationID>
<Reason>Sucess</Reason>
</ResultSet>
</SC_ESP>
Whan I try to POST this XML data via the XSQL Servlet
I get the following error:
"Character '$' is not allowed in a XML tag name."
Anyone (Mark ?) know what it means ?
Thanks
Martin

Hello Mark,
I don't know which time zone you are in but thanks for the very prompt replies.
All I am trying to with this test is provide an XML input test facility via HTTP. The users are supposed to paste the XML into a TextAre using their browser and have that data inserted into the corresponding Table(s) via the XSQL servlet.
The XML schema have already been registered but I note from your other reply that I have not added the annotation xdb:storeVarrayAsTable="true" to the schema tags.
It is worth noting that the whole thing works if I create a simple table that is NOT related to an XML Shema.
You say that you have not had to use the XSQl Servlet. Would you care to say what approach you would use for the above requirement. Shall I set about writing my own Servlet to do this.

How to execute a Java method when row inserted into a database table?

I have the need to fire off a java method when a row is inserted into a database table. I am unfortunately working with MySQL which just recently supported triggers but these new triggers can not execute a Java application on any event.
What I am looking for is an event driven approach such that when a row is inserted into a specific table I can fire off a java method (sitting in a tomcat container) that will take the contents and send it to a web service.
It has been mentioned that JMS may have the ability to poll and monitor a database table. Just wondering if anyone could point me in the right direction.
thanks
JavaTek

A service handler might be the right way to run some code at the end of a service call (another way would be to make use of filters).
First, make sure your static table is merged with ServiceHandlers.
Secondary, change your custom method name into one that is not already in the service definition of COLLECTION_COPY_LOT (preferably a unique method name like collectionCopyLotLastAction that describes its purpose) and remove the following line from your code:
m_service.doCodeEx("",this);Now create a service definition for COLLECTION_COPY_LOT in your custom component based on the original COLLECTION_COPY_LOT (copy paste from the original service definition) and add you own method collectionCopyLotLastAction as the last step in the service. Play with the load order to make sure CS is using your service definition of COLLECTION_COPY_LOT instead of the original.

Fabian

Inserts into Global Temporary Table

I'm working on using a global temporary table in one of my apps. I have a small test run here to isolate the problem. It simply creates the global temporary table, inserts a row, commits and then does a select to see if the insert worked. No data shows in the table when running this. I don't know much about global temp tables, so any help would be appreciated.
CREATE GLOBAL TEMPORARY TABLE AGENT_SILO.AS_TEMP_VALIDATE (
SBI_EMPLOYEE_ID NUMBER,
CURRENT_FLAG char(1),
EFFECTIVE_START date,
EFFECTIVE_END date
) ON COMMIT DELETE ROWS;
INSERT INTO AGENT_SILO.AS_TEMP_VALIDATE(SBI_EMPLOYEE_ID, CURRENT_FLAG, EFFECTIVE_START, EFFECTIVE_END)
VALUES(0, '', SYSDATE, SYSDATE);
commit;
SELECT * FROM AGENT_SILO.AS_TEMP_VALIDATE;

So I wonder what else I'm doing wrong that's really obvious. Here's what i'm trying to accomplish and maybe there's a better way of going about it.
I have a trigger that is supposed to do some validation before the insert is allowed to go through. So here's my approach. I have a trigger fired when there's an insert into the AS_Employee_history table. This passes some of the fields from this insert into a proc (the id, a flag and a couple of dates). Within the proc, i create a global temp table, insert these passed values into the temp table. Then I have a cursor to basically copy the rows from the as_employee_history table that have the same id. Then I can do some selects on the temp table to see if it passes the validation.
I have outputs throughout for debugging and it gets to right after the inserts into the temp table, then the rest of the code doesn't appear to be executed. So it looks like it's failing at the execution of select statements on the temp table. Anything else obvious that I"m missing here?
Here's my proc.
PROCEDURE "PAS_VALIDATE" (STATUS OUT VARCHAR2, v_status OUT BOOLEAN, NEW_SBI_EMPLOYEE_ID IN NUMBER,
NEW_CURRENT_FLAG IN CHAR, NEW_EFFECTIVE_START IN DATE,

ORA-01776: cannot modify more than one base table through a join view

I have created EO based on a database view than consists of two tables, and only one is updateable.
When I try to update a row using EO, I got a following message: "ORA-01776-cannot modify more than one base table through a join view"
In Forms, this issue is resolved by setting "Query Only" property of non-updateable items to "True".
Is it possible to do something like that in ADF BC?
Thanks

Thanks for answer.
When I set "updateable" property to "Never", that attribute is protected from any change.
I'm sorry for incomplete usecase.
I have set up a list of value on that attribute, because it is a lookup field for another table and I need to get an ID from that table.
Basically, I need that attribute to be updateble for BC, but not for database.

Cannot modify more than one base table through a join view

hi guys, my current problem is that i have a datablock based on a view, now all the fields bar 1 are updateable, but this one field that is obtained through a join is displayed, the user can enter data in this field which then pupulates other fields which are required, but this specific field should not be updated. Is there an option to state this as i keep getting the error:
cannot modify more than one base table through a join view
Any help would be greatly appreciated, thanks.

the user can enter data in this field which then pupulates other fields So, using the value of "this field" you then query the rest of the fields? Can you show us the code you use to populate the rest of the fields?
but this specific field should not be updatedHave you tried setting the "Query Only" property of the field to "Yes" and the other DML properties (Ins, Upd, Del) to No?
Also, what is your Forms version?
Thanks,
Craig B-)

Table Operator Vs Materialized View Operator

Hi All,
Could you please give the differences between Table Operator and Materialized view Operator in Oracle Warehouse Builder 11g.
Regards,
Subbu

Below an extract of my notes of the Materialized view. The complete notes are here :
http://gerardnico.com/wiki/dw/aggregate_table
=====Notes=====
Materialized views are the equivalent of a summary table. (Materialized views can be also use as replica).
In a olap approach, each of the elements of a dimension could be summarized using a hierarchy.
The end user queries the tables and views in the database. The query rewrite mechanism in a database automatically rewrites the SQL query to use this summary tables.
This mechanism reduces response time for returning results from the query. Materialized views within the data warehouse are transparent to the end user or to the database application.
This is relatively straightforward and is answered in a single word - performance. By calculating the answers to the really hard questions up front (and once only), we will greatly reduce the load on the machine, We will experience:
* Less physical reads - There is less data to scan through.
* Less writes - We will not be sorting/aggregating as frequently.
* Decreased CPU consumption - We will not be calculating aggregates and functions on the data, as we will have already done that.
* Markedly faster response times - Our queries will return incredibly quickly when a summary is used, as opposed to the details. This will be a function of the amount of work we can avoid by using the materialized view, but many orders of magnitude is not out of the question.
Materialized views will increase your need for one resource - more permanently allocated disk. We need extra storage space to accommodate the materialized views, of course, but for the price of a little extra disk space, we can reap a lot of benefit.
Also notice that we may have created a materialized view, but when we ANALYZE, we are analyzing a table. A materialized view creates a real table, and this table may be indexed, analyzed, and so on.

Query from source table takes lots of time

I have to load data from an Oracle table which has millions of records. The loading knowledge module I am using is 'lkm sql to oracle'.
I see that the query from the source database takes lot of time and doing a full table scan where as it supposed to be using an index.
I dont have any lkm with 'lkm oracle to oracle'. Some how I need to add a hint to this source query. How I can do this?

This LKM is not indicated to large volume of data, try to use LKM Oracle to Oracle (DBLINK), see ODI KMs documentation for more information.
Related to HINTS you can add this with KM options, see that some Oracle ODI11g new KMs already have some options to do it, so you can put the hint on interface options of KM or define the temp index on the interface

Insert records into non base table

Hi
I would like to insert records into a table when a button is clicked. The table is a non base table. I am trying to save records displayed in a form into a history table which is not part of the form. I am using the following code stored in a program unit then called when the button is pressed. It doesn't generate any error but the records are not inserted. Can anyone please help.
hist_id := 1;
cust_name := :CUSTOMER.cust_name;
loan_date := :LOAN.loan_date;
return_date := LOAN.return_date;
FORMS_DDL('INSERT INTO LOAN_HISTORY VALUES'||hist_id||','||cust_name||','||loan_date||','||return_date);

Why do you need forms_ddl built in for a DML statement to be used in form?
U can directly use insert.
hist_id := 1;
cust_name := :CUSTOMER.cust_name;
loan_date := :LOAN.loan_date;
return_date := LOAN.return_date;
INSERT INTO LOAN_HISTORY VALUES (hist_id,cust_name,loan_date,return_date);
It should work perfectly.

Error insert data over db link in table covered by materialized view

What do I need to do to make the insert working properly without deleting my mviews?
Can anyone help me?
Thanks, Matthias

Helllo,
Can you change this on your Materialized View DDL:
REFRESH FAST ON COMMITTo:
REFRESH FAST ON DEMANDThen, if your INSERT and COMMIT works OK then, can you try:
exec DBMS_MVIEW.REFRESH('MVIEW_LOCATIONS')

Adding 2 more rows to a select without inserting rows to base table

hello all,
i have a below simple select statement which is querying a table.
select * from STUDY_SCHED_INTERVAL_TEMP
where STUDY_KEY = 1063;
but here is the situations. As you can see its returning 7 rows. But i need to add
2 more rows..with everything else default value or what exist... except adding 2 more rows.
i cannot insert into base table. I want my end results to increment by 2 days in
measurement_date_Taken to 01-apr-09....so basically measurement_date_taken should
end at study_end_Date...
IS THAT EVEN POSSIBLE WITHOUT INSERTING ROWS INTO THE TABLE AND JUST PLAYIHY AROUND WITH
THE SELECT STATEMENT??
sorry if this is confusing...i am on 10.2.0.3

Well, I'm not sure if this query looks as good as my lawn, but seems to work anyway ;)
I've used the 'simplified version', but the principle should work for your table to, S2K.
As Frank already pointed out (and I stumbled upon it while clunging): you just select your already existing rows and union them with the 'missing records', you calculate the number of days you're 'missing' based on the study_end_date:
