Setting Foreign Keys...

I have a software application that displays all the software purchases by our agency. There is a license table that tells how many licenses there are for that piece of software and the person's name using that license. The relationship is 1 software: many licenses, therefore, the FK to the software table is in the license table. How do I update my FK in my license table, via the form? When a user pulls up the software record and then clicks on the license tab, I want the FK- :p6_software_id to equal :p2_software_id and update that FK is it's null. How do I do this via the form? Also, tell me where on the edit page does this code go?

Doesn't quite answer my question, but let me give more details. I have a software/hardware app that tracks both which is purchased by our office. There is an intersect table between the Sftware table and Hrdwre table called Licenses. A piece of software can be installed on 1 or more pieces of hardware and a piece of hrdwre, of course, can have 1 or more pieces of software loaded on it. The license table only has keys, a PK, that's a seq# and the foreign keys from the sftwre and hrdwre tables. I've tried to use a global variable for each, but that doesn't seem to work correctly. I need the form to insert these FKs. The scenario: Visio is the sftwre and has 3 licenses. deebee is assigned a piece of hrdwre that has Visio. I need the License table to show: PK-1, FK(sftwre)-1, FK(hrdwre)-1. Therefore, when the user enters a piece of sftwre, the form needs to grab that PK from the sftwre table and create the FK in license from :p2_sftwre_id. When I enter the hrdwre record, I need the PK from hrdwre to create the FK in license from :p6_hrdwre_id. And each time I have a piece of hrdwre that has Visio, I populate License with the PK from the seq#, the FK for Visio and the new hrdwre_id, because I've entered another record that Stacy has a piece of hrdwre with Visio on it, making 2 of the Visio licenses given.
Please help.

Setting foreign keys directly

I've discovered that Kodo (2.4.2) does not like it when I set foreign keys
directly in order to define a relationship. If I set the foreign key and
then call the relationship getter, even in a subsequent transaction, null
is returned. Is this something that is prohibited by the JDO spec, a bug
in Kodo, or something else?

Just use the execute SQL query VI (I believe it's in the advanced palette) and feed it the table creation SQL code you already have.

1:M Relationship - No Foreign Key is set

Hello,
I got a problem with 1:M relationships. The data I send is inserted without problems but the foreign key column is never set (null). Its very strange cause the reading works fine.
The Structur: got 2 tables ... Parent_tab and Child_tab.
I got 3 classes ... Parent_class (this one holds an ArrayOfChild_class), Child_class and ArrayOfChild_class (That holds a Collection of Child_classes). (I know its weird but i dont made this stuff, just have to work with it (and live with it)).
So i mapped the Parent_class to Parent_tab and Child_class to Class_tab (nothing unusale there) and made the ArrayOf Class to an aggregate and put it in the parent_class (where it belongs). In the ArrayOf Aggregate I mapped the Child_class 1:M. There I also set the Foreign Key (in this case 1:1 Child to Parent).
So, anyone still there or all lost :-)
Like I said... the reading works fine, but if i try to insert data it didnt set the foreign key. Tried alot but nothin worked.
Hope someone has an idea ...
btw. I am working with Toplink 9.0.3 Build 425.

Foreign key not working in a table control set on a pop-up window

Hi Experts,
I have created a table control using EEWB on BUPA object. I have moved this table control using BUCO transaction to address view. As the address is displayed in BP transaction as a pop-up window, when the error message from the foreign key verification should raise the pop-up window is closed and nothing happens. What I want is the error doesn,t let the window to be closed and show an error message. Any suggestion to achieve that?
Thanks in advance.

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!

Subquery in IF statement in trigger, without using foreign keys

Hello,
I'm investigating ways of writing a subquery in an IF statement, which is placed inside a trigger.
I wanna write smth like IF (:new.jazz not in (select goldies from T where ... )) etc. I don't know whether the fact that the IF is in a trigger adds some additional restrictions. (Does it?)
So far I found the solution described here: SubQuery Comparison in If Statement which I find a bit tacky, I could have the 'cooleststarinthegalaxy' instead of 1 and seems you need to do extra light, but still extra lifting.
I also read about the possibility of using MERGE, which I'm currently researching.
Is there any other way?
Thanks

Say I have tables A(namea varchar(10)), B(nameb varchar(10)), and B contains tuples ('1stname','2ndname').
I wrote a trigger before insertion, for each row, on table A. For a tuple t to be inserted, it should check whether t.namea is in the set of values nameb from B.
E.g., INSERT INTO A VALUES('1stname') should work. But INSERT INTO A VALUES ('3rdname') should fail. You can use a foreign key constraint for that.
If the tables already exist, and b.nameb is declared as UNIQUE (or PRIMARY KEY), then you can say:
ALTER TABLE a
    ADD CONSTRAINT     a_namea_fk
    FOREIGN KEY (namea)
    REFERENCES b (nameb)
;If you had a situation where you really needed to query a table in PL/SQL, and you weren't sure if the query would find anything, you could put the query in its own BEGIN ... EXCEPTION block, and test for NO_DATA_FOUND.
If you're just checking to see if a row exists or not, you can always write a query that is guaranteed to return exactly 1 row, like this:
BEGIN
    SELECT COUNT (*)
    INTO    x
    FROM    b
    WHERE   nameb = :NEW.namea
    AND         ROWNUM = 1;
    IF x = 0
    THEN
        ...        -- print msgs, raise exceptions etc
    END IF;

Foreign key fields not getting populated in datacontrol palette for EJB app

Hi,
I am quite new to ADF and EJB.I developed a jdeveloper application with JSF and EJB tiers.(I am using jdeveloper 10.1.3.5)
For database the default HR database is used.I created the entities for the EMPLOYEES and DEPARTMENTS table.
I also created a session bean and a data control for the session bean.
I am having a JSF page that receives all the details of a new Employee and insert into database (i.e persistEntity)
But the Employees constructor from the Data control palette is not populating the MANAGERID and DEPARTMENTID fields which are
the foreign key constraints for the EMPLOYEES table and hence while trying to persist the entity
with the auto populated fields an error message is thrown.
If I used ADF BC instead of EJB then i could populate all the fields including MANAGERID and DEPARTMENTID.
Is it possible to have two text fields for Manager and Department in the jsf to insert the Employee details with EJB as the Model?.
If possible how do I bind the values of these fields to the Employees entity object in EJB.
Kindly need your insights on this.
Thanks,
Guna.

Hi,
How are you using MANAGER_ID and DEPARTMENT_ID fields, are they exposed as Long (or some other numeric type), or did you map them on the entity, something like this
@ManyToOne
private Employee manager; // this by default uses the column named MANAGER_ID
@ManyToOne
private Department department; // this by default uses the column named DEPARTMENT_ID
.... If you mapped them (which is the right way), when you create an employee you should set these attributes before persisting the entity, by using employee.setManager(manager) and employee.setDepartment(department). Then, the foreign keys get populated automatically by your persistence provider (Toplink).
If you are using data controls, it is a little different process to set the department and manager, but you should take a look at this tutorial http://www.oracle.com/technology/obe/obe11jdev/ps1/ejb/ejb.html , it will hopefully answer a lot of your questions.

Foreign Key Relationships to external associations - Is it really this dodgy or is there a better way?

Hi All,
Let's picture that I have a GW service called Search Helps and within that service I have a PersonalAreas Entity Set which acts as a search help for drop down fields effectively that need to select a Personal Area. I have 3 properties, with Personal Area Id and Company Code being the keys, and the text for Personal Area being the 3rd and last property. You really need to filter PersonalAreas by Company Code otherwise it's a fairly useless result set.
Now within a different GW service, I have an entity called Position which has a single key of PositionId. There is also a a property of company code on this Position.
Now rather than asking the UI developer to get the Company code value and filter PersonalAreas with it directly, I thought it would be nicer for the UI developer just to use the navigation from a specific Position to PossiblePersonalAreas. e.g. Positions('123')/PossiblePersonalAreas returns the entity set of PersonalAreas filtered by the Position's Company Code.
So with that in mind, I add the external model reference pointing at the search helps service; then create an external association via the sneaky External Associations Editor button (that doesn't appear on the Wizard just to confuse you), and set up my Dependent entity to point at the Search Helps PersonalAreas entity.
At this point I really want to tie the Position's Company Code to the PersonalAreas Company Code, but all I can do is set up a referential constraint of PositionId to CompanyCode or have no referential constraint at all (note - in my example I added the referential constraint as there is an issue with navigation keys being provided to external associations from what I can tell - more about this below).
So, without any other option, I go into my GetEntitySet method of PersonalAreas and write something like the following:
CASE iv_source_name.
    WHEN 'Position'.
      READ TABLE it_filter_select_options ASSIGNING <filter> INDEX 1.
      CHECK sy-subrc = 0.
      READ TABLE <filter>-select_options assigning <select_option> INDEX 1.
      CHECK sy-subrc = 0.
      position_id = <select_option>-low.
*     Get company code for position
      TRY.
          CREATE OBJECT o_position
            EXPORTING
              i_position_id = position_id.
          o_position->get_cost_centre_information(
            IMPORTING
              e_company_code = company_code
        CATCH zcx_hr_object.
      ENDTRY.
endcase.
* Continue with retrieving PersonalAreas for given Company Code
<Remaining code not shown>
e.g. I have to assume CompanyCode is actually "Position Id" when the source of this call is from Position (I could also look at the navigation to find this has come from Position but if you're wondering, unfortunately for external associations, the key is not included in this for some reason but the same followup logic of reloading the object would be required).
So the question I'm hoping the answer to is Yes is: Am I missing something in my understanding here?
Thanks,
Matt
Edit since posting and playing around a bit more: Thinking about this further - it's unfortunate, but the navigation property in odata really implies the dependent entity has knowledge of the principal entity and realistically must know how to instantiate it if it needs to get data based on one of the properties.
Now while I'm fine with that (sort of) I think it's wrong that the dependent entity needs to have the required key properties to hold the principal entities as it makes something like a generic search help impossible to do with navigation - Maybe I just need to be done with that and expect filters to be used by UI programmers to find foreign key'ed entities....

Hi Matt,
I'm not surprised that you have an issue with this. One bugbear I have with Gateway is that for some reason the designers don't think any context beyond the immediate preceding navigation node is important. They don't support this within the same service,so it's hardly likley to work in a service reference.
I may be wrong but I don't think GW is OData compliant in this respect. If I have the navigation path /blindservice/FromHereSet(1)/ToAPoints(22)/ToBPoints, it's rather restrictive to say I cannot see the initial key of '1' in the path when I am trying to resolve 'ToBPoints'. If that value - where I started - is key to the context, I have to know it.
Currently the only way to access this context is to embed the 'key history' in the intermediate entities, i.e. /blindservice/FromHereSet(1)/ToAPoints(1,22)/ToBPoints. In my view that is corrupting the URl to suit the limitations of the SAP OData implementation. What's even more confusing/frustrating is that the technical request context appears to be able to store the stacked navigation keys but doesn't make use of this design.
I feel your pain
Ron.

How can I create a new entry without using LOV for foreign keys.

Referring to TUHRA sample application based on HR database schema. JDeveloper 10.1.3.0.4
How can I create a new employee without using LOV for the foreign key "job_id".
On the first page I would like to choose the job_title from adf read-only table.
After clicking on the "create new employee button" a creation form appears in which the job_id field is set with previous selection.

Edited by: user3541283 on 06.10.2008 03:50

Hi,
usually the foreign key is only set if the VO you select is dependent from a master. If e.g. you have DepartmentsVO1 that has an EmployeeVO3 as its nested VO, then creating a new instance of employees automatically add the foreign key. If you add EmployeesVO1, which is not dependent to DepartmensVO1, then the foreign key is not set. So if this is the case in THURA (keep in mind that this is not an Oracle demo but a sample used in a book about ADF) then all you need is to take the independent VO when building the new employee form.

Exception in thread "main"

First off, use the '-primaryKeyOnJoin true' flag when running the reverse
mapping tool so that you can get rid of that useless Xref class and have
a direct relation between Person and Project. See the documentation on
reverse mapping tool options here:
http://www.solarmetric.com/Software/Documentation/latest/docs/ref_guide_pc_reverse.html
But your real problem is that you are creating new objects, assigning
primary key values, and expecting them to represent existing objects.
That's not the way JDO works. If you want to set relations to existing
objects in JDO, you use the PM to look up those objects. If you try to
create new objects, JDO will assume you want to insert new records into
the DB, and you'll get PK conflicts like you see here.
There are several good books out on JDO; if you're just starting out with
it, they might save you a lot of time and help you master JDO quickly.

FOREIGN KEY IS PRIMARY KEY

Hi,
Has anyone come across the following problem?
I have two tables
customer individual
customer_id (PK) customer_id (PK)
customer_id in individual is the primary key for that table. It is also a foreign key ( related back to customer).
If I use JDeveloper to drag in the two tables ( into a class diagraqm), I have a problem.
JDeveloper "sees" the Individual bean foreign key mapping and generates a getCustomer() method (which returns a handle to the appropriate customer bean).
However as it "removes" the getCustomer_id() method(which returns the actual customer_id), the primary_key reference is dropped.
When I try and compile, JDeveloper quite rightly complains with "where is the primary key".
Can anyone help? Do I need to make it a rule that the foreign key is not also the primary key?
thanks in advance,
Kevin

Hello,
I am having the same problem attempting to use a foreign key as a primary key in an EJB 2.0 CMR running on WLS 6.1. If I do not set the foreign key portion of my composite key in the ejbCreate() method I get an error stating that the field cannot be null (and must be set), when I set the field in the ejbCreate I then get an Error in the ejbPostCreate stating that CMR fields cannot be set using the setXXX methods. The entity relations are as follows:
SalesOrder <--------------------------------------->SalesOrderProduct
SalesOrder = (orderid(PK)+orderstatus+salesrepid+contractdate+processdate)
SalesOrderProduct = (orderid(PK/FK)+productid(PK)+qty+unitcost)
The CMR relationship is bi-directional. The SalesOrder entity bean's ejbPostCreate() method
invokes a helper method that attempts to create the salesOrder product entity as part of the salesorder create transaction and that's when I get the errors stated above.
Have or anyone found out how to handle this kind of cmr using the Weblogic server (6.1) and ejb 2.0??
Thanks,
Darryl

Database adapter - table related by foreign key - not picking

Hi All,
we have a Invoke which picks data from database by using the query feature(not polling) of db adapter.
we are picking data from multiple tables.
there is foreign key relation between tables,which we have defined at the db adapter.
Parent - > child 1
> child 2 > child 3
> child 4 > child 5
So we have a case where parent has 3 rows but children tabls have 3000+.
This error is happening in such cases.
Please let me know.

Also for above issue , we increased the timeout in transaction manager
transaction-timeout and syncMaxWaitTime properties as follows:
Property     File Location     This Value Must Be...     Example
transaction-timeout     SOA_Oracle_Home\j2ee\home\config\transaction-manager.xml     Larger than the transaction-timeout value in orion-ejb-jar.xml and the syncMaxWaitTime value.     7200
transaction-timeout     SOA_Oracle_Home\j2ee\home\application-deployments\orabpel\ejb_ob_engine\orion-ejb-jar.xml     Less than the transaction-timeout value in transaction-manager.xml.
Note: You must set all transaction-timeout properties that display in this file.     3600
syncMaxWaitTime     SOA_Oracle_Home\bpel\domains\domain_name\config\domain.xml
where domain_name is the name of the domain to which you are deploying.     Less than the transaction-timeout value in orion-ejb-jar.xml.     240

The above refernece was useful in resolcing our issue.

Delete a user from a table whose name is a foreign key in other tables

Dear All;
I am trying to figure out an easy way to do this. I just recently took someone application who utilized 500 tables. I am trying to delete a user from a table called member_table. However, I am having problems doing so because the user name is a foreign key in other tables which has a relationship with this member_table. I really can't naviagte through all 500 different tables and start deleting the user from each table . hence, I would like to figure out a way to delete the user from the member_table without getting the error message
ORA - 02292 "Integrity Constraint (....) violated child record found

Unless you want to find and re-create all of the FK's that point to that field so you can make them ON DELETE CASCADE (note it is the FK not the PK that has that attribute), you will need to either delete that member id from each of the child tables individually or update each one individually to either null or some valid value in member_table before you can delete the id from member_table.
You can find all of the tables, and the corresponding column_name that have an FK relationship to memeber_table with the following:
SELECT c.table_name, col.column_name
FROM user_constraints c, user_cons_columns col
WHERE c.constraint_name = col.constraint_name and
      c.r_constraint_name = (SELECT constraint_name
                             FROM user_constraints
                             WHERE table_name = 'MEMBER_TABLE' and
                                   constraint_type = 'P') and
     c.constraint_type = 'R';If there are a lot of these, you could use something similar to generate the set of delete/update statements that would be needed.

Problem with foreign key in entity bean in WSED..Plzzzzz help!!!!!

hi all,
m very new to ejb...m crerating container managed entity bean in wsed..The steps I have followed r as follows,
i) created 2 tables in database,one is PARENT with fields ID(Primary Key) and NAME and another is CHILD with fields ID1(Foreign Key) and NAME.
ii)created 2 entity beans... 1st is parent with fields id(key field) and name(promote getter & setter methods to local interface)...2nd is child
(choosed parent as bean super type) with fields id1 (promote getter & setter methods to local interface) and name (promote getter & setter methods to local interface)...
iii)Generated EJB to RDB mapping(choosed crreate new backend folder->meet in the middle->use existing connection->choosed the tables parent & child in the database->match by name->finish)
now m getting an error in Map.mapxmi--->"The table PARENT does not have a discriminator column"...and a warning--->"A primary key does not exist for table: CHILD in file: platform:/resource/NewFK/ejbModule/META-INF/backends/DB2UDBNT_V8_1/Map.mapxmi. Map.mapxmi NewFK/ejbModule/META-INF/backends/DB2UDBNT_V8_1 L/NewFK/ejbModule/META-INF/backends/DB2UDBNT_V8_1/Map.mapxmi"

Hi Sandra,
Many thanks for your response and providing time of yours.
Now, I have done exactly the same thing, but still it is the same.
I have created two new tables as below:
ZAAVREF (Check table)
MANDT (PK)
COUNTRY (PK) Domain:ZAACOUNT (CHAR 10)
ZAAV1 (Foreign key table)
MANDT (PK)
COUNTRY (PK) Domain:ZAACOUNT (CHAR 10)
Then I have created FK on country of foreign key table ZAAV1 and then SE16 (for table ZAAVREF)->Create Entries-> Entered values for Country only->Save....Records entered with valid Country values.
After that SE16 (for table ZAAV1)->Create Entries-->Entered an Invalid country->Save->Still the record entered to the Database successfully....
Could you please let me know where I am going wrong.
I am using SAP R/3 4.7 and creating tables using Tools->ABAP Workbench->Development->ABAP dictionary

Corrupt dump file, foreign keys not generated on import

Hi,
In our refresh job, we get the dump file from production and use it to refresh the schema in UAT.
The dump file thus we got from production seems to be corrupt - as its giving error - "IMP-00008: unrecognized statement in the export file: "
But the error we are getting is for few users, while other users are being imported fine. For the users which got imported fine, the foreign keys are missing !!!
There is no "error" in the import log regarding the foreign keys.
We tried to get the indexfile and it has all "Create Table" statements, along with indexes, primary key, check constraints etc .... only the FOREIGN KEYS are missing.
How can this be explained ?
With Regards,
Shalini.

Some suggestions:
1. Check Note:111384.1 if you are trying to import from the tape directly.
2. You can set a bigger buffer size and check whether the error reappears.
3. If you are trying to perform a full import and the error always seemed to be happening when it tried to import the 56th user, you set init.ora parameter license_max_users (which is set to 55) to a bigger value.
These are apart from the main reason for this error, i.e., corrupted export file or Import internal bug.
