How to handle One to Many relation In BI Data Model

Hi,
I posted this same question earlier but bit in a different way ..
I have may be infact many come across this requirement ..
As you know R3 Multiple Partner functions would be assigned to a single Sales document but when we want to show the same sales report along with Sales document and respective partner functions in BI it is bit difficult because we can not really allow to split the keyfigure values based on Partner functions when they drilled down by Pfunctions ...
Only alternative is to have multiple partner function attributes (columns) like one for each pfunction in one of the Sales Doc Masterdata and define them as navigational attributes..so that all partner functions would be saved
SALES DOC -
PartnerFunction-----AMOUNT
100000----
   ZZ -
5000
100000--   AB--
100000--    BC--
to meet above requirement as per my above proposed alternative looks like as below
SALES DOC -
Partner Function 1--PArtner Function2-- PF3------ AMOUNT
100000--ZZABBC--
5000
So other than this do you see any other better Data Model ??
Could you please share your thoughts on it??
Thanks & Regards,
BRK

Create a view based on VBPA ( Sales partner functions) and VBAK,VBAPor VBEP ( anyone relevant to your case) and create a generic datasource based on that

How to create one to many relation database based on existing Tables?

Let say I have got 10 tables. Out of these 10 tables one table is used to navigate to other tables and at the some time providing some useful information. Therefore other 9 Tables have the identical structure.
The question is, how can I convert these 10 tables into 2 tables, ie each row of first table correspond to the different data of the other table (one to many relation)?

Hello,
>>The question is, how can I convert these 10 tables into 2 tables, ie each row of first table correspond to the different data of the other table (one to many relation)?
I do not quite understand what you ask and I doubt if Entity Framework supports this scenario, since you mentions these tables already exist, after importing them to the designed windows, we cannot modify them or it would throw an error shows the database
and model is mismatched.

How to get data from three tables (A,B,C) having one to many relation between A and B .and having one to many reation between b and c

i have three tables A,B,C. there is one to many relation between A and B. and one to many relation existed between table b and c . how will get data from these three tables

check if this helps:
select * --you can always frame your column set
from tableA a
left join tableB b on a.aid=b.aid
left join tableC c on c.bid=b.bid
This is just a general query. However, we can help you a lot more, if you can post the DDL + sample data and required output.

TopLink11 Tutorial problems with one-to-many relation

Hi,
I installed TopLink 11 and the related tutorial to work in a simple Eclipse project.
Everthing works fine except for the storing of the one-to-many relation in the database.
The tutorial works with employee, address and phone tables/classes. Plain Objects can be stored and one-to-one relations too. However when trying to store a one-to-many relation not the key of the related object (which is at that tome well known) but the object is tried to be entered
in the Logfile I find:

the highlighted section should be 1501 (the key of the employee record)
Any ideas how to fix this?
Thanks Erika

Erika,
You need to specify the other side of the relationship (on the PhoneNumber side), which is done by putting a @ManyToOne annotation on the "employee" attribute in PhoneNumber. That will cause TopLink to know that it is a relationship and not a basic mapping.

JPA: Issue with loading One To Many relation

Hi All,
I have a One to Many relation mapped as below
@Entity
@Table(name="ACCOUNT_TABLE")
public class UserAccount {
     // Attributes
     @Id
     @GeneratedValue(strategy=GenerationType.SEQUENCE,generator="USER_SEQ")
     @SequenceGenerator(name="USER_SEQ", sequenceName="USERS_SEQ",allocationSize=1)
     @Column(name="CLIENT_ID")
     private Long clientId;
     @Column(name="USER_ID")
     private String userId;
     @OneToMany(fetch=FetchType.LAZY, mappedBy="userAccount")
     @JoinColumn(name="USER_ID", referencedColumnName="USER_ID", insertable=false, updatable=false)
     private List<UserRole> assignedRoles;
@Entity
@Table(name = "ROLE_TABLE")
public class UserRole extends BaseEntity implements Serializable {
     private static final long serialVersionUID = -1651953276532642312L;
     @Id
     @Column(name = "USER_ID", length = 30, nullable=false, insertable=false, updatable=false)
     private String userId;
     @Column(name = "BUSINESS_CODE", length = 10, nullable=false, insertable=false, updatable=false)
     private String businessCode;
     @Column(name = "ROLE_NAME", length = 30, nullable=false, insertable=false, updatable=false)
     private String roleName;
     @ManyToOne()
     @JoinColumn(name="USER_ID", referencedColumnName="USER_ID", insertable=false, updatable=false)
     private UserAccount userAccount;
As you may have noticed, the tables are not joined on the Primary key of parent. This is legacy schema and I have to work with it.
Account and Role are joined by the USER_ID column. This I specified by providing JoinColumn.
Then I have a DAO to retrieve the relation based on user id.
public class UserAccountDAOJPAImpl UserAccountDAO{
     private static final String USER_ACCOUNT_BY_USERID = "select distinct ua " +
     "from UserAccount ua " +
     "left outer join fetch ua.assignedRoles ar " +
     "where ua.userId = ?1 ";
     public UserAccount findByUserName(String userName){
          UserAccount userAccount=null;
          List<UserAccount> userAccounts =null;
     Query query = this.entityManager.createQuery(USER_ACCOUNT_BY_USERID);
     query.setParameter(1, userName.toUpperCase());
     userAccounts = query.getResultList();
     if(!userAccounts.isEmpty()) {
          userAccount=userAccounts.get(0);
          return userAccount;
When I test this code ( for the user Id I used in test there are 11 roles )
The SQL generated is correct, when I run the SQL in PL/SQL Developer, it returns the results as expected.
But the DAO method above returns one UserAccount object with List of 11 UserRole objects as expected. But all of these 11 UserRole objects are same, where as the query returns 11 different roles.
I couldn't figure out what I was doing wrong.
Any help is appreciated.
thanks,
Raghavan

@OneToMany(fetch=FetchType.LAZY, mappedBy="userAccount")
@JoinColumn(name="USER_ID", referencedColumnName="USER_ID", insertable=false, updatable=false)
private List<UserRole> assignedRoles;
}What do you get when you remove this @JoinColumn annotation? It shouldn't be necessary. (user_id seems a little suspect as the join column name by the way, I would have expected role_id here...)

Primary one-to-many relation

What is the best practice to identify the primary entity in a one-to-many relation?
Lets asume the following:
I have persons. (Table: PERSON, Primary Key: PERSON_ID)
I have contact points (Table: CONTACT_POINTS, Foreign Key to PERSON_ID)
In the E-Business Suite we have a field PRIMARY_FLAG on the CONTACT_POINTS table. This is either Y or N. Now it is upon the application, to verify that only one primary contact point is set. But there is no check in the database. You can have 2 lines, with primary_flag = 'Y'.
This would make it heavy to do a simple select as:
SELECT p.first_name, p.last_name, cp.phone_number FROM PERSON p, CONTACT_POINTS cp WHERE cp.PERSON_ID(+) = p.PERSON_ID AND cp.PRIMARY_FLAG(+) = 'Y'
Because if you have, by mistake, 2 lines with PRIMARY_FLAG = 'Y', you would get 2 result lines in the query above, which is not wanted.
A second way would be to have the PRIMARY_FLAG field is filled either with Y or NULL. In addition I can set a unique constrain over PERSON_ID and PRIMARY_FLAG and the database will block every try to add a second Y for one person. In that way I can be sure that I either have a primary contact point or I do not have one. So the query will result the same number of lines as there are in the PERSON table. BUT: whenever I go that way, I have to verify my application logic, that every change on the primary flag must set the old primary entry off and then insert or update the new primary entry.
Which one is the best way, in practice? Are there other solutions? What are advantages ?
Best Regards
Alexander

You can create unique function based index on your CONTACT_POINTS table as follows:
(person_id, case when primary_flag = 'Y' then primary_flag else null end)
So as soon as you'll insert another row with Y, you'll get error, but with other values like N, all will be OK.
And yes - I think it is worth to check data integrity in DB :)

Debug level Hibernate log excerpt:
Included in the above description.

That's not the right mapping for the 1:m relationship in Hibernate.
First of all, I believe the recommendation is to have a separate .hbm.xml file for each class, so you should have one for Parent and Child.
Second, you'll find the proper syntax for a one-to-many relationship here:
http://www.hibernate.org/hib_docs/v3/reference/en/html/tutorial.html#tutorial-associations
See if those help.
The tutorial docs for Hibernate are quite good. I'd recommend going through them carefully.

One to many relation doesn't work

I tried without success to get a simple one to many relationship to work.
The select works fine but
I still have problems with insert.
I have two tables on a existing schema:
1     ANAG (ID_ANAG primary key,...)
2     INDI (ID_INDI primary key, ID_ENTITA,...), where INDI.ID_ENTITA points
to ANAG.ID_ANAG
the two classes are:
1     public class Anagrafica
     private int idAnag; //ID_ANAG
     private String ragSoc;
     private String ragSocFonet;
     private String codFisc;
     private String sesso;
     private Integer codTit;
     private Date dtNasc;
     private HashSet indis;
2     public class Indirizzo
     private int idIndi; //ID_INDI
     private long idEntita; //ID_ENTITA
     private long tpEntita;
     private String indirizzo;
     private String localita;
     private String prov;
     private String cap;
     private Anagrafica anagrafica;
the two metadata:

The problem is:
I create a new Anagrafica object and then I try to save it in the
database. These are the SQL
statements that are generated:
INSERT INTO ANAG(DT_NASC, COD_FISC, RAG_SOC_FONET, SESSO, ID_ANAG,
RAG_SOC, COD_TIT)
VALUES (NULL, NULL, 'NATALE', NULL, 971963921, 'Natale', NULL)
INSERT INTO INDI(TP_ENTITA, PROV, LOCALITA, ID_ENTITA, ID_INDI, INDIRIZZO,
CAP)
VALUES (0, NULL, NULL, 0, 971963921, 'via 25 dicembre', NULL)
Why is the value of ID_ANAG (971963921) assigned to ID_INDI and not to
ID_ENTITA?

Get rid of all extensions except the inverse:

<extension vendor-name="kodo" key="inverse" value="anagrafica"/>
</field>
As in the examples in our documentation, all 1-many relations should only
list their inverse 1-1 relation.
Also, make sure your object model is consistent; i.e. make sure you'resetting
both sides of the relation:
indi.setAnagrafica (anag);
anag.getIndis ().add (indi);
Let us know if you continue to have problems.Hi Abe,
I got rid of the unnecessary extensions and I set both sides of the
relation as you suggest but I still have the same problem:
INSERT INTO ANAG(ID_ANAG) VALUES (2088176453)
INSERT INTO INDI(ID_INDI, ID_ENTITA) VALUES (2088176453, NULL)
while I expect
INSERT INTO ANAG(ID_ANAG) VALUES (2088176453)
INSERT INTO INDI(ID_INDI, ID_ENTITA) VALUES (<some ID>, 2088176453)
any ideas?

One-to-many relation sometimes INSERTs child before parent

Hi,
I have a one-to-many relationship, say Company-Employee, that I want to be
managed by the parent entity (Company), so that when I make persistent the
Company, its Employees are also made persistent, and when I delete the
Company, its Employees are deleted. In my Java code, Company has an
ArrayList of Employees, and Employee has a Company member variable.
My metadata looks like this:
<class name="Company" identity-type="application">...
     <field name="employees">
          <collection element-type="Employee"/>
          <extension vendor-name="kodo" key="inverse-owner" value="company"/>
          
          <extension vendor-name="kodo" key="element-dependent" value="true"/>
     </field>
</class>
<class name="Employee" identity-type="application">...
     <field name="company"/>
</class>
I have a test that is creating a Company with an Employee and persisting
it. It then deletes the Company. The test is passing some of the time and
failing some of the time. It seems to not be consistent with the ordering
of the INSERTs - sometimes it inserts Company then Employee, but sometimes
it first tries to insert into Employee, which fails with a foreign key
constraint to the parent table.
How can I force it to insert into the parent table first?
I notice that the documentation says you need the field of the child
entity to be the inverse-owner. Is it not possible for the parent entity
to own the relationship?
Many thanks,
Alex

Alex,
If you have non-deferred foreign keys between the tables, and you turn
on Kodo's foreign key reordering algorithm, Kodo will ensure that all
your foreign key constraints are met, regardless of the ordering of the
operations in your Java code.
See http://docs.solarmetric.com/ref_guide_dbsetup_fks.html for details
about this.
Regarding inverse-owner specification -- is there any reason why you
want to specify this on the other side? inverse-owner basically defines
which side of a shared relationship defines the mappings and should be
monitored for changes; it does not have any impact on the mappings
themselves.

How to implement one to many relationship between two Document Line Table

Hi,
I want to implement the following relationship into user defined tables:
Example Situation:
There are tables A, B and C.
For one record of Table A, there could be multiple records in table B.
For one record of Table B, there could be multiple records in table C.
i.e. A(1) -> B(n) [One to many relationship]
B(1) -> C(n) [One to many relationship]
finally: A(1) -> B(n) -> C(n)
How can I achieve this? If I make Table A as Document and table B & C as Document Line and then make them UDO, will it work? Kindly suggest me a solution.
Regards,
Sudeshna.

Hi,
I think that the database representation is exactly what you ask for. 3 tables, A, B, C. A should have a UDF that is linked to B table, and B should have a UDF that is linked to C table.
You should manage the database transactions, and the UI to support all this stuff.

IBai Peñ

How to handle html:multibox in jsp with ADF Data Binding

Hi,
I like to use html:multibox feature in my jsp with ADF Data Binding. I am able to retrieve checked values in the DataForwardAction form. However, when the page is refreshed, the checkboxes are not persistent and yet an error showing
"JBO-25009: unable to create object type ....oracle.jbo.domain.Array" appears.
Here is my jsp code:
<c:forEach var="type" items="${bindings.SystemTypeView1.rangeSet}">
<c:if test="${Row['SystemGroup'] == type['SystemGroup']}">
<br>
<html:multibox property="selectedSystemType">
<c:out value="${type.SystemType}"/>
</html:multibox>
<c:out value="${type.TypeDesc}"/>
</c:if>
</c:forEach>
Can anyone tell me how to handle html:multibox with ADF Data Binding and make the checkboxes persistent.

Generally this can be done.
I see a problem with your use case, which has nothing to do with jdev or java:
How do you identify the user when he comes back to finish the form?
For this you can't use information like session cookie or IP address because they change.
So you have to save some information about the user which lets you identify him when he comes back. All other requirements can be implemented by ADF.

Many pages and complex data model in JHS app

I am using JHS to create an application containing data that is structured something like:
- Country
- Company
- Department
- Employee
- Payments Details
I have created entity and view objects corresponding to each of these and the appropriate accessors/view links. We need the user to be able to search, work on data and 'drill down' from any level (not always starting with company). In order to make this possible my JHS application has 5 'top level' tabs corresponding to each of the above entities. From each of these top level pages users can drill down to the children.
This works but we end up with many pages and a large data model with lots of replication and nesting.
Country - 5 pages
Company - 4 pages
Department - 3 pages
Employee - 2 pages
Payments - 1 page
total 15
You can picture how the data model is structured. Obviously this is a very simple example but I hope it illustrates my concerns. We have so many pages that post-generation changes are going to be difficult to manage. I'm also worried about the size and complexity of the data model. In this case views are almost all entity based so I guess the data is only cached once but supposing they were not?
Are we using JHS in the best way ? perhaps I'm overcompilcating it ?
I have started to rewrite the JHS generated application so that it (almost) always reuses the same top level generated pages (with some modifications). When the user wants to navigate to a child I modify the whereClause of the target ViewOjbect appropriately, reexecute it and forward to the corresponding 'top level' page. This approach seems to work well, cuts down the number of pages enormously and simplifies the data model (and has enabled me to put breadCrumbs in).
In doing this though, am I creating work for myself that JSH could have done if we had used it differently in the fist place?

This sounds like a valid approach in your situation. We have been playing with the idea of having something like 'Group Links' where you can generate navigation items from one group to the other. Then, you would need to have one, 5 level deep nested group, and 4 other top level groups to provide the search&select on each of the nested groups, but they themselves would not need to have nested groups, but a navigation link to the nested groups in the 5-level deep group.
Although nice and simple in theory, the details are a bit tricky to work out with all the possible layout- and samePage settings, so we have not implemented this yet. So your approach seems a valid one. If you have any suggestions on a way to generate what you are now doing manually, we'll be interested.
Kind regards,

Questions related SQL Developer Data Modeling

1) Is it possible to import ERwin 3.5.2 version(called as Platinum Erwin) erx file to SQl developer data
modeling tool?
2) When this tool going to be released as a standalone Product?
3) One of our requirements is calculating Table and Database size from Data model tool(as a volumetric
report). Is it possible in this tool?. Also i couldn't able to define storage properties(like Tablespace).

I have also replied to you in the feedback application where you logged your query. I have added my response here for others who may be interested.
1)We currently only support import from ERwin 4.x
2) It is company policy not to disclose release dates. We plant to release in 2009.
3) You can define Tablespace using the Physical model. Expand the Relational node and then the physical model. The two nodes you can use for your tablespaces are the Tablespaces and Segment Templates nodes.
