It's possible ON UPDATE CASCADE in table relationships?

Hi, how are you?
Sorry my weak English, I'm brazilian.
I like create an "ON UPDATE CASCADE" in my table relationship but find only "ON DELETE CASCADE" in Oracle 9i Database Online Documentation.
I would like your help.
Thank you.

Tom Kyte wrote a package for this:
UPDATE CASCADE PACKAGE
Generates needed package and triggers to support update cascade in Oracle without removing or infringing on DECLARITIVE RI.
This package supports:
- Tables with multi-part primary keys (primary key(a,c,b))
- Update cascade to many child tables from one parent
- Self-referencing integrity such as that found in the SCOTT.EMP table (mgr->empno)
- Is completely application transparent. The application does not know it is happening
- Versions 7.0 and above of the database.
- Tuned and optimized to fully avoid full table scans on all tables (complete with utility to show you un-indexed foreign keys in a schema, Cascading an update to un-indexed foreign keys can be bad).

Thanks
Prasanta De

Hi Steve,
Thanks for your reply but I could not find any example from the documentation for update-request or delete-request. I need your help in this regards.
1. I have emp table with many rows and the simple structure like this
DEPTNO NUMBER(2)
EMPNO NUMBER(2)
EMPNAME VARCHAR2(20)
EMPSAL NUMBER(8,2)
Key is defined on deptno and empno
2. I have a xml file like this
<?xml version = '1.0'?>
<ROWSET>
<ROW num="1">
<DEPTNO>1</DEPTNO>
<EMPNO>11</EMPNO>
<EMPSAL>1111.11</EMPSAL>
</ROW>
<ROW num="2">
<DEPTNO>1</DEPTNO>
<EMPNO>12</EMPNO>
<EMPSAL>2222.22</EMPSAL>
</ROW>

How to update the VBFA table without entries in VBRK and VBRP tables

Hello,
I have a requirement , where the sales order , delivery happens in one SAP system say X system and billing document wil happens in other sap system say Y.
Now in this particular case , if the user want to know the billing document number in X system. what would be the solution.
Is there any possibility to update the VBFA table with invoice number of Y system (without updating the VBRK and VBRP tables).
User want to see the billing doc number from sales order in the form of document flow in X system
Thanks in advance
Pradeep

Hii
Without updating VBRK/VBRP table and updating VBFA is not possible, So you have to play with work arround to create one Z TABLE, so whenever system Y will create billing document with the reference of System X data you have to update Ztable with Invoice number created in System Y, The primary key will be in Z TABLE is Delivery document number to track one to one with billing doc.
Thanks and Regards

Is it possible to update attributes in all tables in a multi entity view

Hi I have a view based on 4 entities, all of which are a 3 of which are 1 to many relationship with the 4th. The 3 additional entities have 2 or 3 attributes, Id, name, and one entity has a foreign key relating to a different table which I do not care about. The IDs are all updatable in the entity, and none of them are generated from a sequence but are inserted manually, except for the 4th (Master?) which is generated from a sequence.
I create the view and all the entities are updatable, but in the view when I go to attributes from the other tables, it says updatable never and is grayed out so I cannot change it, even though in the entities tab, it is updatable always.
So I was wondering if this was possible to do???

I do not understand really, if it is 2 different tables, it is 2 different primary keys. Why would this even happen? What does it matter if EmployeeID and DepartmentID is both 1??? It just seems that there has to be a simpler way to do this but ok.
So I go to the AppModule, Java tab and go generate Java class. The original code was
public ViewObjectImpl getObjektiCRUDView1()
return (ViewObjectImpl)findViewObject("ObjektiCRUDView1");
I then copy your code to the best of my limited knowledge and get this
public ViewObjectImpl getObjektiCRUDView1()
this.getObjektiCRUDView1().executeEmptyRowSet();
{Row yourRow = this.getObjektiCRUDView1().createRow();
this.getObjektiCRUDView1().insertRow(yourRow );
return (ViewObjectImpl)findViewObject("ObjektiCRUDView1");
On the first row the getObjektiCRUDView1() is underlined and it says missing method body or declare as abstract.
I know I did something wrong here but I have no idea what as I am not very good with Java
Also it is not a jsf page, I create a single jspx page and divided it using the panel splitter so on one side we have an adf table for updating the Objekti database table, and on the other side I have an adf form for updating the Positions table (and later on other tables, I hope to have many forms there)

Is it possible to update internal table from database table

Hello All:
I know how to update database table from internal table in one shot (batch) but is the reverse possible? Can I update some fields in an internal table from a database table in one shot (without looping) because my internal table is huge? Could you please provide me any ideas how to acheive something like this? Thanks in advance and answers will be rewarded.
thanks.
Mithun

Hello my friend,
You can do it MAYBE , i think you can reverse the update doing a ROLLBACK, but only after you update....not after the program finishes..
To update some fields at once use:
UPDATE DBTABLE FROM TABLE IT_TABLE
Hope this helps!!

Is progamatic update to Configuration table (T Table) possible ?

Hi All,
Is it possible to update the configuration (T Table) table (INSERT / DELETE) through program? Is there any restriction ? When I tried to use INSERT statement in my program to update TCJ04, it didn't work.Is it because the client is non-modifiable for config table ? We even can not try BDC as that client is non modifiable.
My requirement is to update TCJ04 table from HR table PA0002. Now I am thinking about feasibility. Any idea ?
Thanks,
Achirangshu

When it is configurable table why dont you update the table in which client you can configure then transport it up.
Configuration tables can be updated using proper key but not a good idea.
Well, you need to check your program - what is sy subrc value after insert?
What is the table maintainance ?
are you using commit work after sy subrc = 0?
Post your code if you are doing all above

Automatic payment program (F110) document are not update in PAYR table

Hi all,
I have make payment in F110 (automatic payment) to customer
But it is not update in PAYR table
Please guide me what I have to do for documents update in PAYR table
Thanks and Regards,
Prudhvi

Hi,
It is possible to enter multiple documents.
You can enter a list of single documents or in intervals.
Enter the document number in ascending order.
Ex:
Individual documents.
10001,10003,10011
If the documents are in a sequence you can enter the Interval like this
(10001,10011)
Hope it helps you

Updates to the table from the database level.

Hi Dear All,
If we do some updates to the table at the Database Level, like i deleted some records from the table at the Oracle level. But I'm still able to see the same deleted records from the Data Dictionary(SE11) at the application level.
Can you pl explain the mechanism, that how it is possible and why.
best regards
Mahesh

transparent tables store data directly....if you delete some data from transparent tables, the same is reflected in the database (oracle) but the reverse is not true...if you modify the database table contents directly...the dictionary table remains intact...
transparent tables have a one-to-one relationship with the database tables....
hope that clarifies a bit....
(somebody correct me if i am horribly wrong)

Equipment not updated in all tables properly

Hi Friends
Equipment was updated in EQUI table with limited data only and not updated in other tables EQKT, EQUZ. When I go through the IE03, there I am unable to find the equipment. Material and serial number provides the equipment, I know it, but if we check it in IQ02 for the serial number with the material, I was unable to see the equipment details those are sales and distribution tab and some tabs not updated and equipment not activated. When I tried to activate the equipment in IQ02, system allows saving the document. When I am coming back, system is giving the update termination error. I think at the time of creating user might have done some mistake, but I am unable to find it
Could you please let me know the reason and possible solution?
Thanks in advance
Ravi

hi
After creating the equipment in IE01 ,you are not able to change in IE02 or display the same in IE03, then kindly check with your basis team for your update termination error

Heeeeelp - on update cascade

hi all
I posted the same question inn this forum but did not get any answer i'll try again in this post
my problem is that i created my tables in the database without on delete cascade on the foreign constraint and now 'm trying to modify that
I dropped the old foreign constraint and created new one with "on delete cascade" this worked fine for one table but when i came to the other tables it gave me this error:
ORA-02443:cannot drop constraint - constraint unavailable
but I'm sure the constraint with the name i used is available !!!
what are your suggestions???
another problem:
how to implement on update cascade in Oracle?
I found a solution in http://asktom.oracle.com/tkyte/update_cascade/index.html#download
but I don't know how to use , if someone knows please help
Thanks in advance

1 .
select constraint_type,constraint_name from user_constraints where table_name='<TABLE_NAME>' and
see if the constraint name that you are trying to delete exists.

Hi I bought a macbook in 2007/2008 and am wondering if it is possible to update the operating system? Here are my system details: Hardware Overview:    Model Name:     MacBook   Model Identifier:     MacBook4,1   Processor Name:     Intel Core 2 Duo   Pro

Hi, I bought a Macbook in 2007/2008 and am wondering if it is possible to update my system so I can get the new version of iTunes?
Here are my current system details: Mac OsX Version 10.5.8
Hardware Overview:
Model Name:    MacBook
Model Identifier:    MacBook4,1
Processor Name:    Intel Core 2 Duo
Processor Speed:    2.4 GHz
Number Of Processors:    1
Total Number Of Cores:    2
L2 Cache:    3 MB
Memory:    2 GB
Bus Speed:    800 MHz
Boot ROM Version:    MB41.00C1.B00
SMC Version (system):    1.31f1

The model 4,1 can run a maximum of 10.7 Lion. The 10.6 Snow Leopard DVD is in the Apple online store. You can get it for $19.99. After you’ve installed that then download the 10.6.8 combo updater to finish it off. http://support.apple.com/kb/DL1399 You will need to be running 10.6.8 to access the App Store to order Lion. http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
System Requirements for 10.6:
Mac computer with an Intel processor
1GB of memory
5GB of available disk space
DVD drive for installation
Some features require a compatible internet service provider: fees may apply.
You can upgrade from 10.5 to 10.6 with no problems as long as you have at least 1gb of RAM. Any program that runs under 10.5 should run under10.6. See this list for third party programs compatibility with 10.6: http://snowleopard.wikidot.com/ You might have to upgrade some drivers for printers, etc.... And you will have to install Rosetta if you have any Power PC applications
http://www.macobserver.com/tmo/article/snow_leopard_installing_rosetta/
Once you are at 10.6.8 Lion is still available from Apple. You will have to call Apple Customer Care 1-800-692-7753 or 1-800-676-2775. to purchase it. Then within 3 days you will get an email with a code which you can use to download Lion from the App Store. Or go to http://store.apple.com/us/product/D6106Z/A/os-x-lion and purchase it there. The price is $19.99.
Lion will require at least 2gb of RAM but really needs 4gb to run smoothly.
As for third party programs see this list for compatibility with 10.7 http://roaringapps.com/apps:table
Also Lion doesn't run any Power PC programs. To see if you have any Power PC programs go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up select Applications under Software. Then look under Kind to see if any of your applications are listed as Power PC. Universal and Intel will run under Lion.
Before Mac switched to Intel processors in 2006 they used Power PC processors from 1994 to 2005. Power PC 601 through 604, G3, G4 and G5. Applications written for the Power PC processors need the application called Rosetta to run on Intel processors. This was part of the Operating System in 10.4 and 10.5 but was an optional install in 10.6. With 10.7 Lion Apple dropped all support for Power PC applications.

ON UPDATE CASCADE and Autoincrement primary key with Oracle SQL Developer

hello everybody,
I want to know if Oracle SQL Developer manage autoincrement on primary key and "ON UPDATE CASCADE" when i migrate (with data) SQL Server database in Oracle database.
Can you help me ?
Thanks for your suggestions.

Obtain the value of the auto increment key with the getGeneratedKeys() method.
Statement stmt = null;
ResultSet rs = null;
stmt = conn.createStatement(java.sql.ResultSet.TYPE_FORWARD_ONLY,
                                java.sql.ResultSet.CONCUR_UPDATABLE);

stmt.executeUpdate(
            "INSERT INTO autoIncTable (dataField) "
            + "values ('data field value')",

Updating a Base Table through a View having UNPIVOT function.

Hi,
I have a requirement of updating a Base Table through a View.
This View has the query using a UNPIVOT function for displaying the columns of the Base tables in rows.
I need to update/insert into/delete the Base Table by accessing the View (The user doesn't have an access to the Base Table, hence the DML's on the View).
Following is the table I've created:-
CREATE TABLE PERSON_DETAILS
PID            VARCHAR2(10 BYTE),
FIRSTNAME      VARCHAR2(1000 BYTE),
LASTNAME       VARCHAR2(1000 BYTE),
PHONENUMBER    VARCHAR2(1000 BYTE),
ADDRESS1       VARCHAR2(1000 BYTE),
ADDRESS2       VARCHAR2(1000 BYTE),
COUNTRY_CODE   VARCHAR2(1000 BYTE),
LANGUAGE_CODE VARCHAR2(1000 BYTE),
EMAIL          VARCHAR2(1000 BYTE)
)The sample values are inserted in this table through the below script:-
insert into person_details values ('1','XYZ','ABC','1234567890','India','Asia','IN','EN','[email protected]');
insert into person_details values ('2','XYZ2','ABC2','1234567890','India','Asia','IN','EN','[email protected]');The code for the view is as below:-
CREATE OR REPLACE FORCE VIEW PERSON_DETAILS_VIEW
   PID,
   CD_NAME,
   CD_VALUE
AS
   SELECT "PID", "CD_NAME", "CD_VALUE"
     FROM person_details UNPIVOT INCLUDE NULLS (cd_value
                         FOR cd_name
                         IN (firstname AS 'First Name',
                             lastname AS 'Last Name',
                             phonenumber AS 'Phonenumber',
                             address1 AS 'address1',
                             address2 AS 'address2',
                             country_code AS 'Country Code',
                             language_code AS 'Language Code',
                             email AS 'Email') );Below are the values from the view:-
PID CD_NAME         CD_VALUE
1    First Name       XYZ
1    Last Name       ABC
1    Phonenumber 1234567890
1    address1         India
1    address2         Asia
1    Country Code   IN
1    Language Code EN
1    Email               [email protected]
2    First Name       XYZ2
2    Last Name       ABC2
2    Phonenumber 1234567890
2    address1         India
2    address2         Asia
2    Country Code   IN
2    Language Code EN
2    Email               [email protected] user would fire some statement like below:-
update person_details_view
set cd_value = 'US' where CD_NAME = 'IN'The above statement should update the base table PERSON_DETAILS.
I understand I can write an INSTEAD OF trigger but I do not know what logic to write in the trigger so that the requirement gets fulfilled.

it is definitively possible with an instead of trigger.
for Example:
create or replace

update person_details_view
set cd_value = 'X|X' where cd_name = 'First Name' and pid=1The logic is: you must convert back the view through pivoting

APEX DB: Not accepting the constraint ON UPDATE CASCADE

Hi
My schema tables is not accepting the ON UPDATE CASCADE constraint as it was accepting the ON DELETE CASCADE constraint. My use case is to update the records in the child tables, when a PK of parent table is modified/updated. Please help.
Thanks
Bhavesh

Bavesh,
Boy this question could spark a huge debate about relational theory and the merits of allowing the update of a primary key... But instead of stirring the pot, I'll answer your question. :-)
Unfortunately Oracle does not support the ON UPDATE CASCADE constraint that PostgreSQL and other databases do.
You might look at [this discussion|http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:5773459616034] on ASK TOM where he talks about the merits and references a couple ways you can achieve similar things in Oracle.
Hope That Helps,
