Child table foregin key contrain violation

Hi ,
1-I have a form containing parant and child table component
child table component becomes visible changes base on drop down present on form
After typing Id , drop down is change ..on its listener createchildtable row is created progarmmatically.
the form gets saved.
2-but after competing all record if i change the first field ID on parent table component and save i get child contrain violation error
What i had observerd that after 2 step my child table view object get current row becomes null
please help

You are deleting "parent" rows.
I am wondering about the locking of "child" table Message. Especially if your query plan shows spools (as noticed by Kev). Theoretically, it is possible that the spool has collected all information, then releases the locks on Message and starts
deleting rows from MessageData. If a "first" "child" row is added to Message for an existing MessageData row, then the delete of the corresponding no-longer-orphaned "parent" will fail.
If this is the case, then you have a choice to make. Which way do you want to resolve the problem? Do you want the insert to be blocked and possibly fail, or are you content with failure of your batch delete?
If you want the insert to be blocked, you could add locking hints to the Message table in the delete query, such as WITH (UPDLOCK, HOLDLOCK).

Cascade update of primary key in child tables

Hi,
We have a typical scenario in which the primary key has to propage to the child table into 3 levels. We are getting the no parent key exception if we create new data into the three tables using 3 level master detail relationship and execute commit operation. The following is the structure of the tables.
Parent_table (sno number primary key, name varchar2(100));
Child_table (fk_sno number primary key, name varchar2(100), foreign key (fk_sno) references parent_table(sno));
GrandChild_table (sno number primary key, fk_sno number, name varchar2(100), foreign key (fk_sno) references Child_table(fk_sno));
The requirement is to update fk_sno in child_table and grandchild_table with the trigger generated primary key sno in the parent_table.
The application module is having the following structure
parenttable
|
----------childtable
|
-----------grandchild_table
If we create new records into parent_table and child_table it is working fine when we commit the data. If we create another record into grandchild_table and commit data we are getting the foreign key violation exception. We are using composition in the association to update the modified values to refresh the data.
Is there any problem in the data model to use fk_sno as primary key and foreign key in child_table.
Thanks and Regards,
S R Prasad

Hmm, another example is CSKS, this logic was probably designed already in the 1980s...maybe it was seen beneficial to be able to select the currently valid record by using the primary key only (the first record where DATBI is larger than system date, not possible when DATAB is the key instead).
Maybe there are better explanations. Why do you need to know this, just curious?

Update key in parent and child tables

Situation:
Parent table (p) has a PK, p.parent_id. Child table (c) has a FK c.parent_id which, of course, points back to PK, p.parent_id.
I need to UPDATE the key in both tables but I am concerned about throwing a FK constraint violation. How does one get around this? Does one update the child first then the parent or vice versa? Seems either way a FK violation will occur...
thank u.

1) If you ever anticipate wanting to update a key, that key should not be the primary key of a table. Primary keys should be immutable. If this is going to happen with any regularity, you need to re-examine the underlying data model.
2) If the constraints were declared to be deferrable, you would simply mark them as deferred, update both tables, and commit (at which point the constraint would be validated). If the constraints were not declared to be deferrable, you will probably need to end up dropping and re-creating one or the other (presumably as a deferrable constraint this time).

How to get the primary key names right for child tables?

I have a logical model with a parent table and two child tables. The engineering strategy is "table per child". The parent has an primary key attribute. This is a screen shot:
https://lh5.googleusercontent.com/-iKMtA3Say5c/UIkG1iktgEI/AAAAAAAAAtc/mrwFeHm4gi4/s800/child_pk_log.png
When I engineer the model I get two primary keys with the same name name, which is the name of the parent:
https://lh3.googleusercontent.com/-N88a9VwoPKw/UIkG1spbXpI/AAAAAAAAAtY/eonf8WdUZ6I/s800/child_pk_rel.png
The correct names would be CHILD1_PK and CHILD2_PK. I can change the relational model by applying the naming rules but the next engineering will trash the names again.
How can I fix this?

Hi,
the problem with PK name is fixed in Data Modeler 3.2.
You can change PK name in relational model it won't be changed on next engineering

Modify Primary Key Value while present in child tables

Hi,
I have one master table having primary key "ESTNO" and 10 child tables having ESTNO as the part of their primary key / composit key. I need to update the value of ESTNO in a master and associated child tables. what should i do to accomplish this...
Regards.

I think the trigger is the best solution to a bad problem. Having just tested it, I can confirm that putting the code in the AFTER UPDATE ... FOR EACH ROW trigger does not require us to make the foreign key deferred (at least in 9.2, I assume that also applies in earlier versions).

Foreign-key autocreation in child table giving issue in the application

Hi,
I am facing an issue with partitioning a table that foreign key relationship is created on the original table with interim table. This gives exception in the application because of its existence. Please suggest me how to get rid of this issue.
Let's say my table T_TABLENAME has to be partitioned. It has a child table T_CHILD_TABLENAME which references (FK_T1) ID column of T_TABLENAME.
While partitioning, COPY_TABLE_DEPENDENTS function copies/creates the key/index/trigger objects for the interim table. [I need copy_constraints => TRUE in COPY_TABLE_DEP call], Fine.
But, after partitioning is done, the foreign key (TMP$$_FK_T1) object exists with the child table which should absolutely not happen as this forms dependency with interim table as well along with parent table.
Here my script goes:
i) Creating interim table
CREATE TABLE T_TABLENAME_PT

Thanks for your information. I am using Oracle Database 10g Enterprise Edition Release 10.1.0.2.0 - 64bit.
1) I am logging the exceptions in a logger table.
2) If CAN_REDEF_TABLE gives exception, flow goes to the final EXCEPTION block and program terminates. So if no exceptions, the other steps comes into the flow of execution.

Update column data to Upper Case in parent and child table

Hi ,
I am facing issue while updating column value to upper case in parent table and child table. How can i do that ?
when updating parent row:
ORA-02292: integrity constraint (XXXXXXXXXXXXXX_FK) violated - child record found
When updatng corresponding child row:
ORA-02291: integrity constraint (XXXXXXXXXXXXXXXX_FK) violated - parent key not found
how can i update on both the places ?
Regards,
AA

I am facing issue while updating column value to upper case in parent table and child table. How can i do that ?
Why do you need to do that?
That is just ONE of several questions you should answer before you start modifying your data.
1. What is your 4 digit Oracle version? (result of SELECT * FROM V$VERSION)
2. If both values are the same case what difference does it make what that case is?hen you don't need to alter your original data.
3. What is the source of the column values you are using now? If you change your data to upper case it will no longer be identical to the source data.
4. What is your plan for enforcing future values to be stored in UPPER case? Are you going to use a trigger? Have you written and tested such a trigger to see if it will even work the way you expect?
5. Why aren't you using a surrogate key instead of a 'business' data item? You have just demonstrated one reason why surrogate keys can be useful: their actual value is NOT important.
You should reexamine your problem and architecture and consider other alternatives.
One alternative is to add a new 'surrogate key' column to use as the primary key. Just create a new sequence and use a trigger to populate the new column. Your current plans will require a trigger to perform the case conversion so instead of the just use the trigger to provide the value.
If the change is being done to facilitate searching you could just add a VIRTUAL column UPPER_MY_COLUMN and index that instead. Then you could search on that new virtual column and the data values would still be identical to the original data source.

Parent table of a child table

I am using a child table 'CHILD_T' and in this table the column 'CHILD_FK' is the foreign key and it is pointing to some parent table. In my oracle editor I can see only synonyms but not actual tables. Is there any way to find out the parent table for this child table. Why I am asking this is because , I am getting below error while trying to execute the below script.
Here I think my question is pretty simple but I would like to know how to find a parent table of a child table as I can see only synonyms instead actual tables.
Script :
INSERT INTO CHILD_T ( EM_ID, DFLT_COST_CNTR_TXT, ACCT_TYP_ID, DFLT_ORD_TYP_ID ) VALUES ('abcd', 'NA', '1', '1' );
Error:
SQL Error: ORA-02291: integrity constraint (AFM.USR_PROF_EM_ID) violated - parent key not found.
Any one have any idea your help is well appreciated.

select table_name from user_constraints where constraint_name in
(select r_constraint_name from user_constraints where constraint_name='YOUR_CONSTARINT_NAME');

Tbale Data Not picked from Child Table while configuring Database Adapter

Hi,
we are experiencing problem while picking multiple records from child table while polling from the database.
details are, lets say we have one Parent table "Student (Id ,College) and one Child Table (Id,Book,Author)
Id is Primary key in Student Table and Foregin in Child Table.Lets say data in tables are
Student Table :196263,"Y.M.C.A"
Child Table :196263,"English","Gill"
196263 ,"Maths","Nagpal"
Now what should be done while polling 1 record should be picked from student table and 2 diferent records from Child Table ..for the above given scenario...
(I have used 1:M Relationship).
But What is happening that from Child Table only first record got picked up 2 times..and record from Student Tablle was being picked correctly.....but in the ideal
Cab anybody help me how to resolve this issues....

Hi Gurus,
I am facing similar kind of issue i.e. after polling on header table (Logical Delete), the header records are updated correctly.
But the problem starts in child table. From Child Table only first record is getting picked up 2 times (if 2 rows are there for that particular header id).
Kindly help.
Thanks,
Abhishek

Why is the child table inserting first in a composite association?

Guys and Gals,
Studio Edition Version 11.1.1.3.0.
This one has gotten me all day. I have a child table which is inserting before its master table, even though the relationship is defined as a composite relationship.
Process:
1) User adds a part with a purchase price into the Part table.
2) Via Part-PartHistories View Link, part is inserted into PartHistories.
3) Via BPL-BPLRows View Link, part is inserted into BPLRows along with its purchase price. The part number is part of a composite primary key (BPL,PartNumber) and is a foreign key to the Part table.
4) Via BPL-PL View Link, and then Via PL-PLRows View Link, part is inserted into PLRows along with its purchase price. The part number is part of a composite primary key (PL,PartNumber) and is a foreign key to the Part table.
It is #4 which gives me an integrity constraint (PCS.PRICE_BUCKETS_PARTS_FK1) violated - parent key not found error. JDev is trying to insert in the order 4,1,2,3 when it should be 1,2,3,4. The kicker is that there is a composite association between #1 and #4 which should guarantee that 1 is inserted first. If I remove #4's process, steps 1-3 run fine. If I remove the composite association, JDev inserts correctly steps 1,2,3,4.
Why is JDev trying to insert #4 first? I do a CreateInsert on the Parts table first so the creation order is correct. Furthermore, there is a composite association defined between Parts - PLRows.
Something is indeed fishy in Denmark.

LovettWB,
You talk about VOs, but composite relationships need to be defined at the EO level. If you have indeed defined the proper composite associations, this sounds like a perfect test case to submit to Oracle Support to evaluate.
If you do have the proper associations set up and things don't work, you could try [url http://download.oracle.com/docs/cd/E17904_01/web.1111/b31974/bcadveo.htm#CEGECADE]this technique as a workaround.

Please help... Foregin key problem

How come foregin key can't work? Someone please help me
This doesn't work. (Item not found)
==========================================================
cursor my_cursor is
Select USER_ID
FROM NETWORK_ACCOUNT
where v_gobal2= ID_NUMBER;
begin
v_gobal2 := :CHECK_ID;
open my_cursor;
fetch my_cursor into v_gobal1;
==========================================================
But how come if i change this line 'where v_gobal2= N_PASS;' or any not foregin key attribute, it work?
By the way 'ID_NUMBER' is a foregin key on NETWORK_ACCOUNT table
while 'N_PASS' is an attribute of the same table
I dont understand??
Below is my NETWORK_ACCOUNT create table
CREATE TABLE "NETWORK_ACCOUNT"
(     "USER_ID" VARCHAR2(20),
     "N_PASS" VARCHAR2(20) NOT NULL ENABLE,
     "ID_NUMBER" CHAR(10),
     "STAFF_NUMBER" CHAR(10),
     CONSTRAINT "NA_USER_ID_PK" PRIMARY KEY ("USER_ID") ENABLE,
     CONSTRAINT "IDNUMBER_FK" FOREIGN KEY ("ID_NUMBER")
     REFERENCES "IDCODE" ("ID_NUMBER") ON DELETE SET NULL ENABLE,
     CONSTRAINT "NA_STAFF_NUMBER_FK" FOREIGN KEY ("STAFF_NUMBER")
     REFERENCES "STAFF" ("STAFF_NUMBER") ON DELETE SET NULL ENABLE
All i wan to is to get the user_id when user input ID_NUMBER

your problem has nothing to do with Foreign-keys!!!
Both the columns that you are using as FKs, you have defined them as "CHAR(10)" (well, because they are CHAR(10) in the parent/referenced tables). Had you defined them as VARCHAR2(10) both in child table (network_account) and the parent tables (idcode and staff), you'd have faced no problem. I m not sure why you are using CHAR(10) but if you change your code like this, it should work:
original: where v_gobal2= ID_NUMBER;
changed: where RPAD(v_gobal2,10) = ID_NUMBER;
When column data type is defined as VARCHAR2, oracle does not store white spaces but in case of CHAR, Oracle will add white spaces if the input value is not of exat length.
I'd strongly recommend you use VARCHAR2.
Hope this helps!
