Foreign keys

I have a summary table that was created off a fact table. The summary table has similar fields as the fact table, including keys that link back to dimension tables. My question is, should there be foreign key constraints defined on the summary table, since the data is coming from a fact table that already validated the data with the foreign keys defined on it (fact)?
create table fact1
(factkey number,
,amount number(21,6)
,state_id number,
foreign key to state_dim table on fact1
Create table summ1
(total number
,state_id number
populate summ1 from fact1
foreign key to state_dim table on summ1 ---- is this redundant?

select table_name from user_indexes where index_name = (select
r_constraint_name from user_contraints where constraint_type
= 'R' and table_name = <child_table>)
I think that should do it.

Problem with Foreign Key relationships in SAP R/3 4.7

Hi Experts,
I am trying to create a foreign key relationship between 2 transparent tables in SAP R/3 4.7
Table 1:ZAAVNDR (MANDT (pk), VENDORNO (pk), NAME, REGION, COUNTRY (fk)) Foreign Key Table
Table 2: ZAAVNDRREF(MANDT(pk), COUNTRY (pk)) ---Check table
I have added few valid countries in check table but when I am adding some records in foreign key table with invalid countries these records are not being restricted and are still successfully going into the table.
Could any one please help in this.
Thanks in anticipation.
-Amit

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

Can not insert null into foreign key issue

Hi ,
I am having parent-child relationship table.
In the child table when I am adding a new record , data is getting inserted with foreign key.
After insert if I immediately update the same record. Its giving error that can not insert null into foreign key.
If i click on rollback button I am able to update that record properly.

Thats obvious from the xml file contents you have given here. In this xml file You have four complex type. Two of them are employee and address. However the employee doesnot have any relation with address as you have not added the relationship. Thats why its failing. Its not the fault of ODI.
Also I would suggest not to use auto generated dtd by ODI as you might face problem in future. For example the address type of XML has 8 attributes and 4 of them are not mandatory. That means each of your xml file may have attributes between 4 to 8. This is where ODI auto generated DTD fails.

How to get multiple row data in single row for one value of foreign key

i want to get data from a table in a way that all the emp_id corresponding to one manager_id
in employee table come in one row. (emp_id is the primary key and manager_id is the foreign key) Since there are different emp_id whose manager_id is same
so how can i get all the emp_id in one row .

One way with 10g:
select mgr,
       rtrim(xmlagg(xmlelement(empno,empno||',').extract('//text()')),',') emps
from emp
where mgr is not null
group by mgr;10g:
-- define this function:
create or replace
function concatenate(c Sys_refcursor, sep varchar2 default null) return varchar2
as
val varchar2(100);
return_value varchar2(4000);
begin
-- open c;
loop
fetch c into val;
exit when c%notfound;
if return_value is null then
    return_value:=val;
else
    return_value:=return_value||sep||val;
end if;
end loop;
return return_value;
end;
select mgr,
       concatenate(cursor(select empno from emp e where e.mgr=emp.mgr order by empno),',')
from emp
where mgr is not null
group by mgr;With 11g:
select mgr,
       listagg(empno,',') within group (order by empno) emps
from emp
where mgr is not null
group by mgr;

Foreign key

How can I insert a row into a table with the foreign key of column ID?
The foreign key link to other unique key of other table.
My code:
Long id = 43850943l;
PreparedStatement persInfUpdate = con.prepareStatement("INSERT INTO PersonalInfo (ID, FirstName, SecondName, Age, GenderMale, Married) VALUES (?, ?, ?, ?, ?, ?)");
persInfUpdate.setLong(1, id);
persInfUpdate.setString(2, personalInfo.getFirstName());
persInfUpdate.setString(3, personalInfo.getLastName());
persInfUpdate.setInt(4, personalInfo.getAge());
persInfUpdate.setBoolean(5, personalInfo.isGenderMale());
persInfUpdate.setBoolean(6, personalInfo.isMarried());
persInfUpdate.executeUpdate();
Error:
INSERT on table 'PERSONALINFO' caused a violation of foreign key constraint 'F1_KEY' for key (0). The statement has been rolled back.

The foreign key must already exist before you can do update.

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!

Can we associate index with foreign key?

hello
i have searched and could not find the answer to the above;
i have a foreign key constraint on the tables; i added an index on that column as well;
however when i query the all_constraints, under index_name for this foreign constraint there is nothing; only when i have PK/UK i case see indexes associated with them;
will then oracle still associate my index with the FK constrained column? or i need to excplicity associate it with the foreign key column? if so, how to do that?
thx

Hi,
UserMB wrote:

"I have a foreign key constraint, where emp.deptno references dept.deptno. (Deptno is the primary key of dept.) I created an index called emp_deptno_idx on emp.deptno as well."
however when i query the all_constraints, under index_name for this foreign constraint there is nothing; only when i have PK/UK i case see indexes associated with them;Not all indexes are associated with a constraint. In the example above, you wouldn't expect to see anything about the index emp_demptno_idx in all_constraints or in all_cons_columns.
will then oracle still associate my index with the FK constrained column? or i need to excplicity associate it with the foreign key column? if so, how to do that?In the situation above, Oracle will still use the index when the optimizer thinks it will help. You don't have to do anything else.

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

Hi,

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;

How to create a foreign key for the table from two different tables?

Hi All,
I have a three table like below. In the below table SAMPLE_CONS_CHECK and SAMPLE_CONS2_CHECK will be having the primary key for NAME column. The same SAMPLE_CONS3_CHECK table also having the primary key for NAME column and forieign key for SAMPLE_CONS_CHECK and SAMPLE_CONS2_CHECK tables. See the below code 2
code 1:
CREATE TABLE SAMPLE_CONS_CHECK
        (NAME VARCHAR2(10),
        SERIES VARCHAR2(5)
CREATE TABLE SAMPLE_CONS2_CHECK
        (NAME VARCHAR2(5),
         MODEL NUMBER
CREATE TABLE SAMPLE_CONS3_CHECK
        (NAME VARCHAR2(5),
         MODEL_NO NUMBER
        )code 2
alter table SAMPLE_CONS_CHECK
add constraint SAMPLE_CONS_CHECK_pk primary key (NAME)
alter table SAMPLE_CONS2_CHECK
add constraint SAMPLE_CONS2_CHECK_pk primary key (NAME)
alter table SAMPLE_CONS3_CHECK
add constraint SAMPLE_CONS3_CHECK_pk primary key (NAME)
ALTER TABLE SAMPLE_CONS3_CHECK ADD
CONSTRAINT SAMPLE_CONS3_CHECK_FK1 FOREIGN KEY
     NAME
) REFERENCES SAMPLE_CONS_CHECK
    NAME
) ON DELETE CASCADE;
ALTER TABLE SAMPLE_CONS3_CHECK ADD
CONSTRAINT SAMPLE_CONS3_CHECK_FK2 FOREIGN KEY
     NAME
) REFERENCES SAMPLE_CONS2_CHECK
    NAME
) ON DELETE CASCADE;From the above schenario i am able to insert the data to SAMPLE_CONS3_CHECK table. But the parent data is already available in the parent table. The problem is here two different constarints from two different tables. While inserting, it is checking from both the tables whether the parent is exist or not.
How can i solve this problem? Can anyone halp me about this?
Thanks

Actually the design is completely incorrect.
What you say is
I have
'foo', 'foo series'
'foo','foo model'
'foo',666
By virtue of table3 referring to both table1 and table2.
This means you actually need to have 1 (one) table:
'foo','foo series','foo model', 666
And the 'problem' disappears.

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.

Transfer data from one database to another without identities but keep the relation b/w PK and Foreign key

Hi,
I need to transfer data from one database to another database (both are identical databases).
1. Not transferring identity columns (primary keys). the destination table might have the same key.
2. keep the PK's and FK's relation b/w parent and child table
3. I have 4 levels
Example: tableA (col1 int identity(1,1) , col2, col3)
tableB (col1 int identity(1,1) ,
col2 , col3) -- col2 has the foreign key relation with tableA.col1
tableC (col1 int identity(1,1) ,
col2, col3) -- col2 has the foreign key relation with tableB.col1
tableD (col1 int identity(1,1) , col2, col3) -- col2 has the foreign key relation with tableC.col1
please advise me.

Performance degradation when using foreign keys

Hi,
I face drastic performance degradation when I add foreign keys to a table and perform insert / update on that table.
I have a row store table to which I need to insert around 1,50,000 records.
If the table has no foreign key reference it takes maximum of 5 seconds but if the same table has references to other tables (in my case there are 3 references), the processing speed reduces drastically to 2 minutes.
Is there any solution / best practice that can help me in gaining performance (processing speed) in this situation?
Thanks
S.Srivatsan

Hi Sri,
When you perform one insert in any database table which is having foreign key relationships, it will check the corresponding parent tables to check whether the master data is available or not. If your table is having 2 foreign key relationship, it happen twice per insert. Hence the performance will degrade. This is one of the reasons why ECC doesn't establish foreign key relationship in the back end database. The case is not just for INSERT, for UPDATE & DELETE the same is applicable.

Editable ALV & Foreign Key Check

I am working on an Editable ALV. Here if I try to enter some value into a field which doesnt exist in the corresponding Check table of the field, ALV throws me an error. This scenario is working fine.
But in some scenarios I populate the ALV table from a Z table (Z table has the same strucutre as the ALV table) and then show this to the user as an editable ALV but in this scenarios if some erroneous values exist in my Z table for a particular fieId I am not getting the Foreign Key check I mentioned earlier. Here I was hoping to get error message after SET_TABLE_FOR_FIRST_DISPLAY !
I am using CL_GUI_ALV_GRID, has anyone found a workaround for this
Antony

Hi Antony,
you can INHERIT a class from CL_GUI_ALV_GRID and then redefine SET_TABLE_FOR_FIRST_DISPLAY adding the raising EVENT data_changed for all cells.

In ADF how can i insert data in multiple table if they have foreign key

I have started working on ADF and can anybody inform me in ADF how can i insert data in multiple table if they have foreign key,please?
Thnak you very much.

Hello,
Still no luck.I am surely doing silly mistakes.Anyway,Here are my workings-
1> student_mst (id(pk),studentname) and student_guard_mst(id(fk),guardianname)
2> created EO from both of the tables,made id in both EO as DBSequence and an association was also generated.
3> i made that association composite by clicking the checkbox
4> i created 2 VO from 2 EO.
5> put those VO in Application Module.
6> dragged and dropped 2 VO on my jspx page and dropped them as ADF Form.
Now what to do please?

Using one user account table across multiple databases but account used as a foreign key

I want to use one user account table from one database and use it across a couple other databases. The problem is that I want some tables to use the primary key from the user account table as a foreign key to access the data when the user logs in. Is this
the right way of going about it? Do I have to create a user account table in all my databases? What is the best practice to handle this problem? Thanks in advance.

You can use Triggers or using replication.
