Foreign key in many to one relationship causes redunency

Hi
suppose I have two tables
A and B
Table A has a primary key A_PK number
Table B has a primary key B_PK number
The relation between two tables is M to One
if B_PK is foreign key on table A
then it causes redunency
A_PK B_PK
1 1
2 1
so what the best way to solve like this problem?
thanks

thanksIt's not sure from your description exactly how/where/what columns are involved in the FK relationship. You either have no problem, or your problem is that you have two tables with the same PK, meaning you haven't normalized your design.
As suggested, post actual table defs, not just a vague description.

Many-to-one relationships

I'm trying to implement a many-to-one relationship similar to the one, for example, between an OrderLineItem and a Product.
I managed to create the beans and define the relationship using deploytool.
What I'm trying to understand is how can I prevent a Product instance from being deleted when it is involved in the relationship described above?
Currently, under Sun's reference implementation server, I am allowed to delete a Product even if there are OrderLineItems that reference it.
There is one line printed out in the window running j2ee -verbose:
com.sun.ejb.containers.EntityContainer$EJBTxKey
The record in the Product table is deleted nonetheless.
Another weird thing is that the server does not allow me to deploy two beans involved in a many-to-one relationships with the Product bean if they are using the same CMR field name. What I get is a compilation error at the deployment time.
I'd appreciate any input.

They way I handle this is to hide the creation/manipulation/deletion of the bean behind a manager - for example a singleton session bean. I NEVER allow the direct creation/deletion of entity beans except through manager classes. This is quite a common J2EE pattern, whose name escapes me at the moment.
Your manager would have a method like delete(int productId), which would delete the matching Product entity bean, and would then search the OrderLineItem beans for the matching Product primary key.

Many to one relationships strange behavior

I have a problem with two many to one relationships.
The problem appears from the dirty mechanism of cmr/cmp fields.
When I have two “many-to-one” relationships ex:
A n..1 B
A n..1 C
Navigability: B -> A
A <-> C
When I put in ejb-jar.xml the B to A relation first, the bugs appear. The dirty mechanism work chaotic. The problem is in the generated code for the PersistenceManager and Wrapper of the A bean.
In the Wrapper the only fields with dirty mecansim are the real fields from bean which are navigable. In the PersistenceManager class are the same fields like in the BeanWrapper plus the fake fields for relationship. But the fake fields are intercalated with real fields and the dirty flag values are not the same with the dirty flags from BeanWrapper. Result: chaotic updates.
Solution(workaround – not elegant): put first the relation which has navigability from A to C and second A to B.

Many-to-One relationship with composed key

Hi all,
I have problems inserting an entity with a 1:n-relationship.
The relationship is defined over two columns. In detail:
There are two database-tables:
VERDECK
ID_PROJECT NUMBER (key)
ID_INTERN   VARCHAR2(10 BYTE) (key)
UZSB
ID_PROJECT          NUMBER (key)
ID_UZSB             VARCHAR2(10 BYTE) (key)
ID_PROJECT_VERDECK NUMBER
ID_INTERN_VERDECK   VARCHAR2(10 BYTE)
On UZSB there is a referential integrity defined between these tables:
FOREIGN KEY (ID_PROJECT_VERDECK, ID_INTERN_VERDECK)
REFERENCES R57SCHRAUB.VERDECK (ID_PROJECT,ID_INTERN))
This is mapped into JPA as follows:
@Entity
public class Verdeck implements Serializable {
     @EmbeddedId
     private VerdeckPK pk;
     @OneToMany(cascade={CascadeType.ALL},mappedBy="verdeck")
     private Collection<Uzsb> uzsbCollection;
@Embeddable
public class VerdeckPK implements Serializable {
     @Column(name="ID_PROJECT")
     private BigDecimal idProject;
     @Column(name="ID_INTERN")
     private String idIntern;
@Entity
public class Uzsb implements Serializable {
     @EmbeddedId
     private UzsbPK pk;
     @ManyToOne
          @JoinColumns({@JoinColumn(name="ID_PROJECT_VERDECK", referencedColumnName="ID_PROJECT"),@JoinColumn(name="ID_INTERN_VERDECK", referencedColumnName="ID_INTERN")})
     private Verdeck verdeck;
@Embeddable
public class UzsbPK implements Serializable {
     @Column(name="ID_UZSB")
     private String idUzsb;
     @Column(name="ID_PROJECT")
     private BigDecimal idProject;
I try inserting a new entity VERDECK with some associated UZSBs as follows:
Verdeck einVerdeck = new Verdeck();
VerdeckPK myKey = new VerdeckPK();
myKey.setIdProject(idProject);
myKey.setIdIntern(lsId);
einVerdeck.setPk(myKey);
Uzsb lsUzsb = new Uzsb();
UzsbPK lsUzsbKey = new UzsbPK();
lsUzsbKey.setIdProject(idProject);
lsUzsbKey.setIdUzsb(lsId);
lsUzsb.setPk(lsUzsbKey);
lsUzsb.setVerdeck(einVerdeck);
Vector<Uzsb> uzsbColl = new Vector<Uzsb>();
uzsbColl.add(lsUzsb);
einVerdeck.setUzsbCollection(uzsbColl);
em.persist(einVerdeck);
As result I get the error
"ORA-02291: integrity constraint (R57SCHRAUB.SYS_C0022330) violated - parent key not found"
Does anybody have an idea? I think the problem could be the embedded key in Verdeck.
Perhaps I should take this into account in my JPA-definition of the relationship?
But how can I do this?
Regards,
Christoph

Hi Christoph,
our JPA implementation does not sort sqlstatements in the right order to work with foreign keys. This feature will come with the next release. The problem here is that databases check the constraint for every statement executed instead of checking at commit time (when our state is ok again).
As workaround you can set the settings for the foreign key constraints to deferred (pls. see oracle docu: alter table defferrable / alter session deffered) and the database will check at commit time. Second approach would be to delete the foreign key constraints.

Foreign Key To More Than One Column

Hi Guys,
I have a requirement like below
I have 3 tables (Prospect,customer,user) and I have a contact_dtls table .
In prospect table Prospect_id is the primary like this customer_id in customer table and user_id in the user table
in the contact_dtls table I have a column contact_id and other cols.The contact_id can be from prospect_id,customer_id and user_id in other words we can tell the prospect can be a contact or the customer can be a contact and the user also can be a contact also.Now the question is "is it possible to maintain primary key and foreign key relationship with this design that means the prospect_id,customer_id and user_id would be the foreign keys to the contact_dtls table
I am using oracle11g Version

Hello,
as it has been said in the previous reply, you cannot have a foreign key on multiple tables. Maybe you can create a new table contacts containing at least an id column. This table will be parent to prospect, customer and user. Now contact_dtls.customer_id can reference the contacts.id column.
This will also make sure, that the ids from prospect, customer and user are unique. It even will be possible that a contact is user and customer at the same time.
Regards

SD Billing document many to one relationship with sales order

Hi experts,
We have a scenario where we have done collective billing for some time. So, obviously we have from sales order to billing one to many relationship. Meaning, one sales order has many billing docs.
Now, we want to merge the sales order (VBAP) data with billing data (VBRP). But, we want to take only one billing document which is appropriate.
For example, we have a sales order, corresponding that we have a billing debit memo followed by a cancellation, followed by another debit memo. In this case we have to take the third debit memo as it is the latest and the first one has a cancellation.
We will know alll this through VA02 Tcode. However, we want to derive this logic off of the above tables. We are actaully clue less as to how to pick up the right billing doc from VBRP for a sales order out of many.
Please post ur replies.
Thanks.

Hi Jain,
Thanks for the reply. The sort out mechanism may not be the one we are looking for. There may be several DIFFERENT billing docs for a single sales doc. More over, these billing docs may have been created on the same date. So, what we are looking for is a fied or information like XBLNR in VBAP with which we can for sure eliminate all other billing docs and cancellations against them, for exmaple, and pickup the right billing doc alone.
I relly appreciate your efforts.
Thanks.

Many to one relationship !

Hi All,
i have one query having Rental Unit and Measurements.
in reality one Rental unit has many measurements but when i run the query it shows me only one measurements per Rental Until!
any clue ? how can i get all the measurements for each rental unit ?
please help.

in the cube do you have both of these values
PT02 211886
PT02 211887
or its always either one of them. I dont think changing your cube design would prove any helpful in this scenario. I believe its more of a data issue than the design issue. You would need to change the way the data is entered into the cube with the different measurement assigned to the unit.
on a second thought(I understand that you dont have a luxury to change the cube design), when you say you can see diff measurement type assigned to one unit in the masterdata, you can make the unit attribute as a navigational attribute in both the IO and cube. And just map measurent type in the update rules and derive the units from the masterdata table in the report.... does it make sense?

How to update the foreign key in a 1-to-many relation ?

I have Product mapped to Channel as 1-1, and Channel mapped to Product as 1-M. Product has a nullable channel_id_fk as a foreign key to Channel, (so one can optionally specify or change the channel of a specific product).
Starting with a specific product with a null channel_id_fk, I
1) add this product to a channel (with a vector of products via ValueHolderInterface);
2) set the channel of this product; and
3) update the channel in a unit-of-work.
The product.channel_id_fk doesn't get updated in db.
I tried setting each side of the relation as read-only, but still it doesn't work.
What am I missing ?
(I am using toplink 9.0.4)

More info:
1) There is only a single uow involved, so there is no nested transaction.
2) I tried checking the "target foriegn key" in the 1-1 mapping from Product to Channel, but this resulted in a exception thrown during runtime when the channel is accessed from the product:
Local Exception Stack:

Binding for table produces list for other tables using foreign key and crea

Using
software Jdev 11G, WLS 11G, Oracle DB 11G, Windows Vista platform
technology EJB 3.0, jspx, backing beans, session bean
I cannot create a namedquery on my secondary table. The method for the column uses the entity object rather than the name and value of the column.
For instance,
(Coketruck) table has inventory records(Products) table
Coketruck has one to many to the Products table
Products has a many to one to the Coketruck
I need to return the products from the product table based on the CokeTruck but I cannot create a namedQuery because the method in the Product table is an entity object type instead of a long that I can use to look up all the products based off the column truck_id.
This is what I was expecting…
Private Long truckId;
public Long getTruckId() {
return truckId;
public void setTruckId (Long truckId) {
this. truckId = truckId;
Instead this is what I have…
@ManyToOne
@JoinColumn(name = "TRUCK_ID")
private Coketruck coketruck;
this. coketruck = coketruck
public Coketruck getCoketruck() {
return coketruck;
public void set Coketruck (Coketruck coketruck) {
this. coketruck = coketruck;
How do I do a query on the Product table to return all the products that are in the coketruck?
If I do the following it expects for me to pass the Entity Object which I cannot use as search criteria for my find method.
@NamedQuery(name = "Products.findById", query = "select o from Products o where o.truckId = :truckId")
On a different note but the same song…
I noticed that when I look at my Session Bean Data Contols that the coketruck already has a list of the products. I have created a jsp page with a backing bean and have been able to use the namedquery on the coketruck entity to retrieve the productList. Unfortunately I need to sort the products by type and was also not able to find where to perform the work to be able to iterate through the productList to get my desired display. Therefore I started looking at doing another namedquery that would only retrieve the product_type ordering by the truckId.
Seems I have come full circle… I don’t care what method I have to use to get the info back.
Any help is greatly appreciated!

Hi!
I work on an application wich uses a shopping cart stored in a database. The shopping cart uses two tables:
CART: Holds information common for one shopping cart: the user it is connected to etc.
- Primary key: CART_ID
CART_ROW: One row in the cart, e.g. one new product to buy.
- Primary key: ROW_ID
- Foreign key: CART_ROW.CART_ID references CART.CART_ID
From the code the rows in the cart are collected per cart, as is modelled by the foreign key. There exists one more relationship, which we use in the code, but which is not modelled by a foreign key in the database. One row can be dependent on another row, which makes the other row a parent.
CART_ROW has a column PARENT_ID which references CART_ROW.ROW_ID.
Should we add a foreign key for PARENT_ID? Or are there any questions to consider when it is a foreign key to the same table?
I suggest to add foreign key it wont harm the performance (except while on insert when there would be validation for the foreign key). But it would prevent users to insert wrong/corrupt data either through code or directly by loggin in the database.
A while ago we added indexes, both on ROW_ID and on PARENT_ID. Could the index on PARENT_ID have been harmful, since there is no foreign key?
Index on parent_id would only be harmful if you do not make use of index after creating it (i.e. there is no query which make use of this index).
And if you decide to have a foreign key on parent_id then I suggest to have index too on parent_id as it would be helpful atleast when you delete any record in this table.
Best regards!

All my classes are inherited from StateOwner.class and only the RTerritory class has "one-to-many" and "many-to-one" relationships. When I add rterritory.xml to persistence.xml I have the following error (before all works fine):
log4j:WARN No appenders could be found for logger (org.springframework.context.support.ClassPathXmlApplicationContext).
log4j:WARN Please initialize the log4j system properly.

If I make "parentTerritory" and "children" transient - all works well. Above workes also (comment out and without transient) on OpenJpa.
What do I do wrong if I use TopLink?
This is part of my applicationContext.xml
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceXmlLocation"
value="/META-INF/persistence.xml"/>
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.TopLinkJpaVendorAdapter"/>
</property>
<property name="loadTimeWeaver">
<bean class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"/>
</property>
</bean
Thanks a lot.

Hello.
Thanks a lot for answer.
When I comment out and remove transient I obtain the following exception:

I can't understand What do I do wrong when I include "one-to-many" and "many-to-one" mapping? I want to note it (above mapping) works rightly if I use OpenJpa and one works rightly with TopLink if I remove one-to-many and many-to-one and do them transient.
Thanks a lot.

Many-to-one synchronization

I'm using DataServices to manage hiberate objects. I have a simple many-to-one relationship between Account and Transaction (an account has many transactions). I have two DataGrids in my application, one display accounts and their balances(which are derived from the trasactions, there is no balance field) the other displays transactions. When I edit the accounts, the changes are propogated to the child transactions. However, when I edit the transactions, the changes are not propagated to the accounts automatically. If I edit the account or resort the columns it will update the balance. My data-management-config.xml is below. My question is, is there a way to make this work or is this not working by design? I want my Account objects to automatically get the new Transactions associated with them so the balance will update correctly.

Ed: Thanks for your response, I think I have a better idea of what is going
on now.
Regarding the first question: In this case I am just modifying an attribute,
the relationship between them remains the same.
I verified that adding a transaction does not update the size of the
transaction collection the account has if I add the new transaction to the
transactions collection. However, if I add the transaction to the
appropriate accounts list of transactions it does update the collection
(i.e. there is one more element) but it does not update the balance. I have
since changed my balance to a property that is calculated by a query server
side. I noticed that even if I change a property on the account, it will
not update the balance unless I call fill again.
So I have two questions: 1) is there a way to make the account realize it
has transactions added to it without adding them directly to the account's
transaction collection? 2) Is there a way to force the account object to
refresh the balance (i.e. re-run the query to generate it?). I realize I
can call fill() again client side and easily fix this, but I would like to
do this in a way that causes all clients to have their account balances
refreshed when the should i.e. I want the server to automatically push the
new balance property. If it matters I'm using HibernateAssembler. Could I
extend that to achieve this?

A question about foreign key to multiple tables

Hello everybody,
I have a question about creating foreign key and I would appreciate if you could kindly give me a hand. Here are my tables:
CREATE TABLE TEAM1(team_id VARCHAR2(20), project_id VARCHAR2(20));
ALTER TABLE TEAM1 ADD CONSTRAINT PK_TEAM1 PRIMARY KEY(team_id);
CREATE TABLE TEAM2(team_id VARCHAR2(20), project_id VARCHAR2(20));
ALTER TABLE TEAM2 ADD CONSTRAINT PK_TEAM2 PRIMARY KEY(team_id);although the structure of both the tables is exactly the same, the values (in particular team_id) in both tables are different.
Also I have another table named AGENT
CREATE TABLE AGENT(agent_id VARCHAR2(20), team_id VARCHAR2(20));
ALTER TABLE AGENT ADD CONSTRAINT PK_AGENT PRIMARY KEY(agent_id)Now the problem is that the column team_id in AGENT table is actually a foreign key, but the value can be in either TEAM1 or TEAM2. As far as I know a foreign key points only to one table.
How can I deal with this problem? Whenever there is an INSERT or UPDATE I have to make sure that the value of the column "team_id" in the table "AGENT" is a valid value either in "TEAM1" or "TEAM2"
Thanks in advance,
Kind Regards,
Dariyoosh

Do you have the ability to change the data model? If so a more appropriate structure may be something like this:
CREATE TABLE TEAM(team_id VARCHAR2(20), team_name VARCHAR2(20));
ALTER TABLE TEAM ADD CONSTRAINT PK_TEAM PRIMARY KEY(team_id);
ALTER TABLE TEAM ADD CONSTRAINT UK_TEAM UNIQUE (team_name);
CREATE TABLE TEAM_PROJECT(team_id VARCHAR2(20), project_id VARCHAR2(20));
ALTER TABLE TEAM ADD CONSTRAINT PK_TEAM_PROJECT PRIMARY KEY(team_id, project_id);
ALTER TABLE AGENT ADD CONSTRAINT FK_TEAM_PROJECT1 FOREIGN KEY (team_id) REFERENCES TEAM(team_id);
CREATE TABLE AGENT(agent_id VARCHAR2(20), team_id VARCHAR2(20));
ALTER TABLE AGENT ADD CONSTRAINT PK_AGENT PRIMARY KEY(agent_id);
ALTER TABLE AGENT ADD CONSTRAINT FK_TEAM FOREIGN KEY (team_id) REFERENCES TEAM(team_id);Edited by: Centinul on Jun 25, 2010 10:50 AM

Many-to-One user mapping to backend systems - possible?

My apologies if this simple question has been asked many times earlier - I couldn't find it if it is so.
I understand I can use user-mapping in single signon to map user X in portal to user A in backend system (say SAP BI).
Can I map users X, Y, Z..... to one backend user A?
What alternative I have (to let a number of portal users run some BW reports on the backend system - for which we want to use only one BI user-id)?

An easier more manageble way of doing this is to create a group and assign the group to a backend user. That will establish your many to one relationship.
We perform this for our vendors currently as they would like to see a single shopping cart in SRM.
Just be cautious on the manner in which you leverage your single user as you can experience several locked objects depending on how things are accessed. Another thing to consider is making the backend user a service user as this will also allow you to change the password mapping policies on the users as in many cases you will need to remap the users every N days depending on your systems security parameters.
Hope this helps.

Select with One-to-Many and Many-to-One without repeating

Hi
I have a customer who needs a report two sides left and right, but allowing for One-to-Many and Many-to-One relationships in the one report.
A little background:-
This has do do with listings on land and buildings.
One building can be built on a few pieces of land.
Similarly, there can be several buildings on one piece of land.
What is required is a listing of buildings on the left, land on the right, but without repeating the "single line entries" either left or right.
For example Building1 is on Land1 and Land2, and Building2 and Building3 are built on Land3.
We need:-
Building1 Land1
________Land2
Building2 Land3
Building3______
The ___ just used for spacing so you get the idea ;)
Essentially - a "break by" on columns on the left and right.
The Buildings and Land are in different tables, with a link table - one row for each link.
Any ideas?
Thanks
Mike

To jitu.jk - first, this is not in SQL*Plus - its a report in APEX - second, I see no way to break on the left and the right in the same select.
Maybe there is a way.
To Etbin
This is a very inovative solution - I've tried it out and the result is:-
BUILDING LAND
_____Land 4
_____Land 3
_____Land 5
Building 2 Land 4
Building 3 Land 1
_____Land 4
Building 4 Land 4
Building 5 Land 3
_____Land 4
(The underscores I put in for spacing - not perfect but you get the idea - hard whe you write the reply in a fixed space font and it's displayed in the forum in variable space font!! ;)
9 rows selected.
This is not quite the desired result - in your list of associations, we have Building1 associated with Land 3,4, and 5.
So for Building 1 we should have:-
Building 1 Land 3
________Land 4
________Land 5..........
But your result doesn't include Building 1 at all.
The other requirement is that no building or land is ever repeated - so I came up with the concept of "groups".
Starting with one building - I find all pieces of land that are associated - listing them on the right (without repeating the building.
I then find any other buildings asociated with any of the land records that the first building was associated with.
These are listed on the left - without repeating the land records on the right.
This group is given a unique identifier of the minimum association ID (my associations have ID's).
This all done, I use the unique ID as a break column ans summarise additional columns (area, value etc) below each group.
Because of the summaries - adding area and value etc, I can't have any building or land duplicated as I would then "double count" the area, value etc.
Maybe you method can be made to work with some tweaking.
Very clever indeed - forums need great answers like this - it keeps us going.
Thanks again
Mike
