Updating parent record owner to top 1 child record owner?

I am trying to understand how to update a parent record's owner field to the value of a child record's owner field, but while there is only ever one parent record, there are multiple children, and I want to update the parent owner value to the owner
of the first child record ever created for said parent.
So for example, if the first child record created was owned by Joe Smith and the second child record created was owned by Betty Boop, I want to update the parent record to being owned by Joe Smith since he was the owner of the original child record.
Key fields are Parent.ID, Child.ID, Parent.Owner, Child.Owner, Child.DateCreated. Hope that makes sense! It seems like using top 1 would be needed but I'm not entirely sure how to use it correctly with an update statement. I am generally pulling data not
updating it, so I'm a bit out of my element.
Thanks,
Shaunna

UPDATE t2
SET Owner = t1.Owner
FROM Parent t2
INNER JOIN Child t1
ON t2.ID = t1.ParentID
WHERE NOT EXISTS
SELECT 1
FROM Child
WHERE ParentID = t1.ParentID
AND DateCreated < t1.DateCreated

How to update child record when item from parent record changes

Hi, I have a master and detail form with two regions on the same page.
Region one references parent record, one of column in the parent record is also in the child record. And is one to many relation
between parent record and child record. How can I have the column on the child record updated when the column of the parent record is being modified?
For exemple; Parent record has two columns : ID and Program.
Child record has Program, goal# and status. I have two pages established, page 27 and page 28.
Page 27 list out all programs from parent record, by clicking on edit to a program, it braches to page 28 with program listed as editable field in region one, and mulitple records list in region two from the child record with the same program.
The problem that I am having is once the program in region one got modified using ApplyMRU, the program in child record did not get updated with the new value and therefore those record become orphan records. I need a way to update all current child records with the new program value.
Thanks in advance for anyone who can hlep out on this problem.

One Idea is
If possible create a after update database trigger on the parent table to update the relevant child record.
Next one
Create a PL/SQL process on the parent page with process sequence next to ApplyMRU, so when the ApplyMRU is seccessfull it goes not to your process where you can have your update statement

UPDATING child table based on the mods to parent record

I have a one to many relationship between Table A and Table B.
I have a field in both of my tables that tracks the status of the record in each table. ie: submitted, inprogress, done.
When records are created in Table A and B, status is set to SUBMITTED. When the application is being reviewed, the status in parent table is changed to INPROGRESS. As soon as the status in Table A changes to INPROGRESS for the parent record, i also want the status in Table B to change to INPROGRESS for the corresponding child records.
How can I do this? Triggers is one of the solns, but is there something that i can do with the PROCESS option available on the parent form?
Any help is very much appreciated.

Hi,
Firstly, as Oracle is a relational database, you shouldn't need to have the setting on a child record where it will always be the same as the parent record.
Secondly, a trigger is probably a better place to make the update, if you need to do this, as this would also handle updates outside of Apex.
Finally, yes you can create a process to do this if you want. You can create an unconditional process (that is, it runs whenever the page is submitted) and does something like:
UPDATE TABLEB
SET STATUS = :P1_STATUS
WHERE FK_ID = :P1_PK_ID
AND STATUS <> :P1_STATUSAndy

How to update parent and child tables while updating parent table

I have a parent table EMPLOYEE which includes columns (sysid, serviceno,employeename...) sysid is Primary key, serviceno is Unique key and I have child table DEPENDENT includes columns (sysid,employee_sysid,name,dob...) here again SYSID is primary key for DEPENDENTS table, employee_sysid is Foreign key of EMPLOYEE table.
Now I want to change SYSID (using sequence) in EMPLOYEE table which need to be update in DEPENDENTS table as well
Note: I have 10000 records in EMPLOYEE table as well as I have 5 more child tables which need to update new SYSID.
please help me

first disable the FOREIGN KEY Constraints.
you can update Parent as well as Child record also with help of trigger.
here i am giving you one examlpe..it may help u.
create table parent(id number primary key,name varchar2(100))
create table child_1(id number primary key,p_id number,dob date,
CONSTRAINT FK_id FOREIGN KEY (p_id) REFERENCES parent (ID))
create table child_2(id number primary key,p_id2 number,addr varchar2(1000),
CONSTRAINT FK_id2 FOREIGN KEY (p_id2) REFERENCES parent (ID))
insert some test data to parent and child tables.
alter table child_2 disable constraint FK_id2
alter table child_1 disable constraint FK_id2
CREATE OR REPLACE TRIGGER delete_child
BEFORE UPDATE ON parent
FOR EACH ROW
BEGIN
UPDATE CHILD_1
SET P_ID=:NEW.ID
WHERE P_ID=:OLD.ID;
UPDATE CHILD_2
SET P_ID2 =:NEW.ID
WHERE P_ID2=:OLD.ID;
END;
then Upadte parent table primary key col and check the child tables.
then enable the constraints...

To find all the child records are processed before parent records

Hi,
When i am trying to process consignment pulls and my client is using third party tool to insert the data into interface tables. My logic is written in such a way that it should pick parent record associated with child but there is some delay in child records and not all the child records are being pulled with parent.
In a brief, i need to write a condition in such a way that my parent cursor should pick all the child records with max(last_updated_date) and then it should be processed.
eg: I have a family and need to catch bus with all my family members. I need to check now for the last family member who get into and should wait for atleast 2mins so as to ensure all my family members are in. I am unable to achieve this with count. Please do revert back soon.
Details are below:
CURSOR c_pull (p_pull_id NUMBER) IS----------------------------------parent cursor
SELECT ecp.ROWID ROW_ID
,ecp.*
FROM consignment_pulls ecp
WHERE ecp.process_flag IN ( 2, 3 )
AND ecp.pull_id > NVL(p_pull_id,0)
ORDER BY ecp.pull_id
FOR UPDATE OF ECP.PROCESS_FLAG NOWAIT;
CURSOR c_line (p_pull_id NUMBER) IS----------------------------------child cursor
SELECT ecpi.ROWID ROW_ID
,ecpi.*
FROM consignment_pull_items ecpi
WHERE ecpi.process_flag IN ( 2, 3 )
AND ecpi.pull_id = p_pull_id
FOR UPDATE OF ecpi.process_flag;

Hi Helios,
Thanks for the info. But its not a concurrent request something like we can filter with start date and completion date. Its all about selection of records from headers and lines table and not able to make those selection of header records with a delay of say some 2minutes until all the child records are inserted.
Thanks,
Prathyusha.

Sum child list items and update parent total using javascript

I have a SharePoint 2010 Parent/Child list setup using a lookup field to join both the lists, this is working well.
The Parent list contains requisition requests and the child list contains related item details. Each of the related child list items has a 'Line Item Total' field. I need to aggregate the Line Item Totals in the child list and place the result in a 'Requisition
Total' in the parent. So for any given parent record the sum of it's related child 'Line Item Totals' is reflected in the 'Requisition' total in the parent row.
I am struggling with the JavaScript code below. I am trying to aggregate Line Item Totals for a given Requisition#? Could someone please review and advise?

$("input[title='Old Amount']").attr("readonly","true").css('background-color','#F6F6F6');
   // Retrieve the name of the selected parent item.
   var strParent=$("select[title$='Requisition#'] :selected").text();
splist li = web.lists["ReqDetails"]; // This is the child list

    splistitemcollection items = li.getitems(q);
    foreach(SPListItem item in items)
    sum += parseInt(item["LineItemTotal"], 10);

I do something similar for a PO Header/PO Detail set of lists. I use SPServices to pull the data.
I put this code in the child edit page - so any time any child is edited, the parent is updated. I get all children records and total them up (except for the item I'm displaying at the current time. I add that value in directly from the form itself.

Deletion of child records linked to parent records to be deleted etc..

'Combined with WHEN OTHERS, SQLCODE provides a way for you to handle different, specific exceptions without having to use EXCEPTION_INIT pragma. In the next example, I trap two parent child exceptions, -2292 and -2291, and, then take an action appropriate to each situation:
PROCEDURE delete_company (company_id_in IN NUMBER)
IS
BEGIN
DELETE FROM company where company_id = company_id_in;
EXCEPTION
WHEN OTHERS THEN
DECLARE
error_code NUMBER := SQLCODE;
error_msg VARCHAR2(512) := SQLERM;
BEGIN
IF error_code = -2292 THEN
/*Child records found. Delete these too */
DELETE FROM employee WHERE company_id = company_id_in;
/* Now delete parent again */
DELETE FROM company WHERE company_id = company_id_in;
ELSIF error_code = -2291 THEN
/* Parent key not found */
DBMS_OUTPUT_PUT_LINE('Invalid company id' || TO_CHAR(company_id_in));
ELSE
/* This is like a WHEN OTHERS inside a WHEN OTHERS */
DBMS_OUTPUT_PUT_LINE('Error deleting company, error: ' || error_msg
END IF;
END;
END delete_company;
Sourced from Oracle PL/SQL Programming (3rd edition) P.143
1. Are error_code and error_msg assigned automatically or do I have to include assignments? If yes, how?
2. Where do I get a list of commonly caught Oracle error codes and similar code snippets used for business logic?
3. How would you deal with the situation where you detect a parent while you are deleting a child record? Just warn the user and log it hoping the DBA will review the logs?
4. I work within a project where I could not query any parent-child relationships, using, amongst other queries the following query, and, this means that the programming team might not be creating these relationships within the database (Oracle 11g).
What are the technical risks?
Could I be omitting something, because it seems quite incredible to me that parent-child relationships are not in place?
SELECT a.table_name,
a.column_name,
a.constraint_name,
c.owner
FROM ALL_CONS_COLUMNS A, ALL_CONSTRAINTS C
where A.CONSTRAINT_NAME = C.CONSTRAINT_NAME
and a.table_name=:TableName
and C.CONSTRAINT_TYPE = 'R'

This is bad code, very very bad code. Throw it away and start with a clear idea of what you want to do.
Why is this code very very bad? Because it uses WHEN OTHERS not followed by a RAISE.
Why is this code bad code? Because it uses one WHEN clause instead of several.
Here is an example for handling multiple exceptions:
http://docs.oracle.com/cd/E11882_01/appdev.112/e25519/errors.htm#BABFBHGA
If your error code does not have a predefined name, define the name yourself:
http://docs.oracle.com/cd/E11882_01/appdev.112/e25519/errors.htm#BABIIEFC
If you keep the WHEN OTHERS at the end, be sure to add RAISE so the exception still exists. If you don't, Oracle will not do the automatic rollback it should be doing.
To answer your question about parent-child relationships, it is very important to have them. They stop you deleting a parent that has children, but they do not stop you from deleting children.

Delete the parent records and child table records at a time

hi all;
I am facing the pbm like to delete the all records in child table and corresponding records in parent table at a time. so I want to delete the all the records in child table and corresponding parent records in parent table by using single SQL query. plz help me
Thanks in advance

You want to use one single SQL statement to delete the child records in a table and the corresponding master records in the master table??
That's not quite possible with a single SQL, of course unless you are talking about Oracle Forms, where you have a relation and set the delete behavior to Cascading, like said in the above posts.

How to obtain parent record from child record in relationship using API

Hi,
I have a record in the main table that is the child in a parent/child relationship to another main table record. Using the Java API, how would I obtain the parent record in the relationship where I am starting with the child record? In the API there seems to just be calls for getChildren, but not a getParent type call.
Appreciate any immediate help that can be provided.
Thanks,
Eddie

Hi Eddie,
Please follow the below steps to retrieve only parents of a child Record.
1. Create RetrieveRelationshipsCommand.
2. Set the parameter RelationshipId.
3. Set the parameter Anchor Record and Anchor Record Id. In this case the child record for which parents records to be retrieved.
4. Set the parameter setGetChildren as false . This retrieves only the parent records for the specified child reocrd.
5. Execute the RetrieveRelationshipsCommand.
6. Retrieve member records from above step.
Hope it helps

I'm inserting values in three tables , making a form having add , delete and edit buttons.
Issue when i want to delete a record from PAR table , it gives child table record exists . i have did manual coding to delete the child records with related to the selected parent table PAR.
Is there any process in ADF to delete the child records with respective selected parent record with out manual coding.

How to find child records is exists before to delete parent records.

Dear Everyone,
I would like to ask you, is there any simple way to find child records is exists before to delete parent records.
I have a master table defined primary key and I have referenced that as foreign key in many tables.
I have used Delete_Record to delete but it isn't display the message 'child record exist' but it cleared the record from the form. So I need to know how to find child records is exists or not before to do delete_record so that I can display message in-case it exists.
I do know we can able to check in every table matching the column manually, but what if we use 100 of tables then it is not possible to check manually.
I am sure there must be simple way to find as how the oracle identifies when we execute delete query.
Please help me on this.
Thanks in advance.

Simple solution is to run the query I have given for all child tables or to try a single query for all child tables withj something like:
select <parent_key>
from <parent_table>
where <parent_key> in
          (select <foreign_key_1> from <child_table_1> union
           select <foreign_key_2> from <child_table_2> union
           ... );More complicate solution could be to change the foreign key constraints to cascade DELETE on parent table to child tables:
SQL>
SQL> create table p(x int primary key);
Table created.
SQL> create table c1(x1 int);
Table created.
SQL> create table c2(x2 int);
Table created.
SQL>
SQL> alter table c1 add constraint fk1 foreign key(x1) references p;
Table altered.
SQL> alter table c2 add constraint fk2 foreign key (x2) references p;
Table altered.
SQL>
SQL>
SQL> insert into p values(1);
1 row created.
SQL> insert into c1 values(1);
1 row created.
SQL> insert into c2 values(1);
1 row created.
SQL> commit;
Commit complete.
SQL>
SQL> alter table c1 drop constraint fk1;
Table altered.
SQL> alter table c2 drop constraint fk2;
Table altered.
SQL>
SQL> alter table c1 add constraint fk1 foreign key(x1) references p on delete cascade;
Table altered.
SQL> alter table c2 add constraint fk2 foreign key (x2) references p on delete cascade;
Table altered.
SQL>
SQL> delete p where x=1;
1 row deleted.
SQL> commit;
Commit complete.
SQL> select * from p;
no rows selected
SQL> select * from c1;
no rows selected
SQL> select * from c2;
no rows selected

Updating multiple records from single form (ASP)

I have a nested repeat region.
I have created in the parent, a form with 3 fields and an update button.
the child records all have multiple columns, 3 of which correspond to the parent.
Athe parent is bound to the child records by the shipmentID
I need to be able to update all child records from the form in the parent.
The case is this.
The child records are orders with shipdates and frequencies
The parent contains a form with fields for shipdate and frequency
The administrator needs to change the shipdate and/or frequency for all child records.
(The child records are forms as well--but that's another issue that works fine)
Shipment ID
Date Field
Freq Field
UPDATE Button
ShipmentID
Record 1
Data case1
Date
ShipmentID
Record 2
Data case 2
Date
I am doing this in classic asp with an SQL database.
So how do I get the form to update all record
[Subject title edited by moderator to make clear ASP involved]

Hi,
This is one of those questions that would require far more explanation that is reasonable to expect in a forum. You should do a little poking around in the nearest Barnes & Nobles. About a half hour in a chare with a good ASP book and vanilla latte should have you on the right track.

Cursor to Update Multiple Records

Hi all
Oracle forms V6
I am trying to use a cursor to update multiple rows associated with the change of a single value, the tables are related but not directly through the values I am trying to change. The form is multi-tab with a block per tab. On the first tab a value entered into a specific field is subsequerntly used in another multi-record tab when the time comes to fill this in, the value is automatically inserted, and this works fine.
If there is multiple records in the second tab then the value from the parent record will be displayed in all records in the 2nd tab because it is automatically taken from the parent record.
I am trying to use a for-loop cursor to update more than one row when the parent value is updated, at present it only updates one row, yet a message I put in cursor shows the different values being stepped through in the cursor. I don't have much experience in this area yet but it looks like the actual form cursor needs to be moved to the next record to update that as well, as you change to this tab you can see the first record being updated but not the second.
Cursor is in the when validate item on the first tab/block.
DECLARE
v_cvs_val VARCHAR2(100) := :b1.new_value;
CURSOR c_cvs IS
     SELECT b2.pk, b2.oldValue
     FROM T1
     WHERE T1.pk = :b2.pk;
     --result set of cursor is all records relating to current parent record
     mcec_rec c_cvs%ROWTYPE; --declares record of cursor type
BEGIN
     IF :system.record_status = 'CHANGED' AND :b2.pk IS NOT NULL THEN
     OPEN c_cvs;
     LOOP
     FETCH c_cvs INTO mcec_rec;
     :b2.oldValue := v_cvs_val;
     EXIT WHEN c_cvs%NOTFOUND;
     END LOOP;
     CLOSE c_cvs;
     END IF;
END;
Any suggestions as to where i'm going wrong would be very much appreciated.

Do I understand correctly? It looks like you have a parent-child relationship where one of the fields on the child table has to be updated when the parent record is changed, but ONLY if the record exists in the child datablock. You don't want to update the child records which exist on the database but not in the block.
go_block(child);
first_record;
loop
:child.item := :parent.item;
exit when :system.last_record = 'TRUE';
next_record;
end loop;
go_block(parent);The code has a go_block so cannot be called from a when-validate-item trigger. You could start a timer in that trigger and run the code when the timer expires. However, the when-validate-record trigger might be better as you will not be able to navigate to the child block if there is an invalid field in the parent (eg if a not-null field is blank).

Update parent status based on all children status and sum of children amount.

Hi,
I need to write sql query for the following scenarios.
We have 3 financial systems (sys1, sys2, sys3) where a same transaction gets entered independently into each system OR entered into one and exported to the other system. Transaction need not be in all 3 systems.
We need to create reconcile report to see the status of transaction and display if it is reconciled or not. For this, in our stored procedure we are pulling data from 3 systems into temp tables and using CTE and other logic marking each transaction status
in each system temp table. One of the systems (eg sys1), we made it as source.
Sys1 temp table has both parent and child records and are distinguished using type. Sys2 and sys3 has only children records. When report is created, we are showing parent from sys1 temp table and
children from new temp table where children status is updated based on availability of it in all 3 systems.

After going thru lot of other logic, final temp table will have only children with status assigned. The above temp table data is only for 1 scenario.
The following are status of children.
This is how status of children is determined:
Not Settled – All child records start as Not settled in temp tables.
Settled – when record exists in sys3 and other criteria is met.
Partially settled – record exists in sys3 and either in sys1 or sys2 or other criteria is not met.
Reconciled – child record should exist in all 3 systems and all criteria is match
Mismatched – record has wrong amount when compared in any of 2 systems.

My part is to update the status of parent based on children status and parent amount must match sum of child amounts. If amounts don’t match, then leave the status of parent as null.
Determining the status of parent:
Not Settled – None of children has yet settled.
Settled – All children are settled.
Partially settled – some of children are as settled OR 1+ children are partially settled.
Reconciled – All children are reconciled.
Partially Reconciled – some children are partially reconciled.
Null – 1 or more childen has a status of mismatched.
AND sum of children amount should match parent amount
How can I update the status of parent based on all children and sum of amount of children equal to parent amount.
Thanks,
Spunny

Your design is fundamentally wrong. In RDBMS, we want to have one fact, one way, in one place in the schema. The goal of all databases is to remove redundancy, not increase it. This not just SQL; this was true for hierarchical and network databases before them!
>> We need to create reconcile report to see the status of transaction and display if it is reconciled or not. For this, in our stored procedure we are pulling data from 3 systems into temp tables and using CTE and other logic marking each transaction
status in each system temp table. One of the systems (eg sys1), we made it as source. <<
You have re-invent the worst of 1970's file processing, but you want to use a temp table instead of scratch tape. This is not RDBMS or good SQL.
>> Sys1 temp table has both parent [sic] and child [sic] records [sic] and are distinguished using type. Sys2 and sys3 has only children [sic] records [sic]. When report is created, we are showing parent from sys1 temp table and children from new temp
table where children [sic] status is updated based on availability of it in all 3 systems. <,
The terms “child” and “parent” are not part of RDBMS. They come from network databases. You are building fake pointer chains we do have referenced and referencing tables. Or do you mean to model weak and strong entities? Where is the DRI actions?
These things are not tables! They have no keys, so they are called (garbage) piles. But even the garbage is wrong. There is no generic “id” in RDBMS; it has to be “<something in particular>_id” to be valid. Since you do not do math on it, it should not
be a numeric.
A “rec_type” is a nominal scale, so it cannot be a numeric either! Likewise, we have no generic “status”, but a status is state of being so it has to have a temporal dimension. And did you know that “reference” is a reserved word in SQL as well as another ISO-11179
violation.
The MONEY data type does not do correct math. Google it! It is another Sybase left-over that nobody should ever use.
Finally, you used the old Sybase INSERT INTO ..SELECT..), .. disaster instead of the ANSI/ISO Standard VALUES table constructor.
>> This is how status of children [sic] is determined: ..
My part is to update the status of parent [sic] based on children [sic] status and parent [sic] amount must match sum of child [sic] amounts.<<
Your narrative describes what Tom Johnston called a Non-Normal Form Redundancy. We do not put summary data in the strong entity; another basic data modeling principle. We build a VIEW that gives us the current summary. Your mindset is still in punch cards and
magnetic tape files.

Can't Delete Parent Record - On Delete Cascade is set

Greetings all,
I have a parent and child table and when I attempt to delete the parent record, I get the following error:
ORA-02292: integrity constraint (WFSTEADMAN.INCIDENT_NOTES_TBL_FK) violated - child record found
     Error      Unable to process row of table MYTEST_INCIDENTS.
I have the the FK set to ON DELETE CASCADE so I am not sure what the issue might be.
Below are the structures of my parent and child tables:
I am using apex.oracle.com so the version is: Application Express 4.0.2.00.06
Any assistance would be appreciated.
Wally

Yeah there was a rampant child table still left out there. Noticed the issue and deleted the child and all is well now. :). Should have looked for a couple more minutes before posting.
Thanks

Updating parent record owner to top 1 child record owner?
