Child records limit

Hi all,
Is there any requiered -or recomended- limit on the number of child records a form should have?
I'm specially concerned about reconciliation performance with the posibility of thousands of child records...
Thanks,

Is there any control on the number of child records returned

Hi,
I am using web services 1.0 to return child records for an account. Is there any control over the number of child records that are returned. From what I can see it is above the default for 10 for parent record query and i would guess it returns up to 100 records?

In DSP 2.5, the 'streaming' api (which can be used only from a client in the ALDSP server instance) does not have a limit to the size of the results. The standard DSP 2.5 api causes the results to be materialized in memory - so you are limited to what memory you have available. (also, WLS server has a default limit of 10M for a request/response - can be increased in the WLS console - I think it's under 'Protocols').
The JDBC api has no limit on the result size - you might be better off using this for a reporting tool.
In DSP 3.2, there is no limit on the result size.

Open dialog box window with checkboxes for each child record - Please Help

Hello Everybody
I have a 10g form with master record and 20 child records. In the child record form, currently there is a “Notes” Editor, which pops up when user click the “Edit” button. In the “Notes” editor, user enters remarks if anything is missing. For example, typical remarks will be: Statement is missing, LOC paper is missing etc.
Now, I would like to replace “Notes” editor with a dialog box. In the dialog box , I would like to add checkboxes with values “Statement is missing” and “LOC paper is missing” etc. along with “Notes” field. The user can select checkboxes. The value of the checkboxes should go in the “Notes” field with the ability to edit it. This way, user doesn’t need to type the most common notes every time.
I have created a “NewNotes” dialog box with checkboxes and multiline text Item. It is pops up when I click on the button. I have also created to WHEN_CHECKBOC_CHANGED trigger for each checkboxes so that the its value will go in a multiline text item.
But, I am not sure how I can link “NewNotes” dialog box to the each record in child record block. I would really appreciate it if anybody could give me some idea.
Thanks,

if i understand correctly you have a note item (based on table) on every child record? when you open the dialog box: how do you put data from notes to dialog box? in the same way as you can write it back ...

How to delete the child record from the database

how to delete a parent and child record from the database can we do it in the servlet and my database is oracle

I'm not sure I understand the question but you could certainly use the JDBC API from within your servlet to access and modify a DB. You could also use an EJB layer to access your DB and accomplish the same tasks.

How to create Child record at the time of master record creation.

Hi,
I have MasterVO and ChildVO. And association between both are 1 to *. I have a requirement like, I need to create row in ChildVO at the time of MasterVO row creation.
I have used entity based association to create view link. This view link created ChildVO accessor in MasterRowImpl as type RowIterator.
Actually my idea is to override create method in MasterVORowImpl and call ChildVO ViewObject and call .createRow() method on it. But I don't have access to ViewObject, instead it gave access to RowIterator.
Could you please provide any pointer to achieve above functionality?
Many thanks in advance.

Hi Tim,
Now it is creating child record at the time of master row creation. But it is working only through BC tester. But when I drag the child VO instance in the jsff page, only master is get created as editable only, child is displayed as read only without populating any default values like child VO surrogate key and other default attributes. But through BC tester it is working fine.
Am I missing anything here while implementing in UI?
Thanks,

Facing problem while deleting a child record in hibernate.

I am trying to update a child records i have following scenario
master record (having one to many assciation with child table cascade=all in .hbm.xml configuration file) ===> customerInfo
detail record set (having many to one assciation with master table cascade=all in .hbm.xml configuration file) ===> customerAccountsSet
i do following steps to update a record
1) get the customerInfo objetc from session successfully
2) get the customerAccountsSet = customerInfo.getCustomerAccounts();
3) traying to add a new customerAccount say customerAccount1 to be saved for the first time without primery key in it
4) traying to update a customerAccount say customerAccount2 to be updated with primery key in it
5) traying to add a delete customerAccount say customerAccount3 with primery key in it
only step 5 is not executed properly as i can still see the deleted record in db , although save and update steps have been successfully completed in db.
can anybody tell me whats going wrong here.code for steps 2,3,4,5 is as follows in the same order
2)Set customerAccountSet = (Set) customerInfo.getCustomerAccounts();
3)customerAccountSet.add(customerAccount);
4)customerAccountSet.add(customerAccount);
5)customerAccountSet.remove(customerAccount);

Hi Nitesh,
1) Java stack should be up while trying to connect to R/3 backend.
2) You can check the JCOs by doing the following:
                       Type the following url   http://<server name>:<port number>
                       Click on Webdynpro Console
                       Enter the user name and password.(You need the system admin right on the EP to do the same)
                       You can find the JCOs.
3) Better you contact the basis guy who had created the JCOs earlier and get the JCOs tested.
Hope it helps.
Regards.

Inserting parent /child records from a xml file ...

XML file pasted below:
I have loaded the xml file into a table called xml_demo which has a column xml_data of type xmltype.
The select for parent record is as follows and it works:
INSERT INTO balit_submissions (balitdoc, documentversion, datetime_from,job_id, status,creation_datetime)
(SELECT 'MOL'
,to_number(extract(x.xml_data,'/MolDocument/DocumentVersion/@v'))
,to_date(substr(extract(x.xml_data,'/MolDocument/ValidTimeInterval/@v'),1,16),
'yyyy-mm-dd"T"hh24:mi')
,123456
,'CREATED',
NULL
FROM xml_DEMO x WHERE
existsnode(x.xml_data,'/MolDocument/DocumentIdentification[@v="MOL_20100331_1500_1600"]') = 1)
Having problem creating child records. From this file I expect to create 3 records.
insert into balit_energy_blocks
SO_ID,
DATETIME_FROM,
DIRECTION,
BLOCK_NUMBER,
ENERGY,
LAST_SUBMIT_DATETIME,
PRICE_POUNDS,
PRICE_EUROS,
BALIT_REF,
STATUS,
LAST_EDIT_DATETIME,
MOL_REASON,
ACQUIRING_SO_AREA)
(SELECT 'RTE'
,to_date(substr(extract(x.xml_data,'/MolDocument/ValidTimeInterval/@v'),1,16),
'yyyy-mm-dd"T"hh24:mi')
,DECODE(extract(x.xml_data,'/MolDocument/MolTimeSeries/Direction/@v'),'AO1','Up','Down')
,to_number(substr(extract(x.xml_data,'/MolDocument/MolTimeSeries/ContractIdentification/@v'),19))
,to_number(extract(x.xml_data,'/MolDocument/MolTimeSeries/Period/Interval/EnergyPrice/@v'))
,sysdate
,null -- price pounds
,null -- price euro
,extract(x.xml_data,'/MolDocument/MolTimeSeries/ContractIdentification/@v')
,'SUBMITTED'
,'A96'
,NULL -- acquiring area
,sysdate
FROM xml_DEMO x WHERE
existsnode(x.xml_data,'/MolDocument/DocumentIdentification[@v="MOL_20100331_1500_1600"]') = 1)
For example, there are 3 ContractIdentification tags. Example of 1:
<ContractIdentification v="RTE_20100331_1500_16"/>
I was expecting this select to pluck the last number from this string. In this case 16.
The select was:
to_number(substr(extract(x.xml_data,'/MolDocument/MolTimeSeries/ContractIdentification/@v'),19))
The result I got was:
16RTE_20100331_1500_20NG_20100331_1500_6
All contractident values are concatnated and returns from position 19 onwards.
Can anyone help me to extract the last number from each ContractIdentification tag value and to create the 3 records
Thanks

Hi,
The result I got was:
16RTE_20100331_1500_20NG_20100331_1500_6In the query you tried, you access a single record so you can't expect to get three rows "magically". The EXTRACT function just works as expected, it extracts the requested nodes, but the result is still an XML fragment (a scalar value).
In order to achieve your goal, you have to break the MolTimeSeries sequence into relational rows.
Two similar solutions are possible, XMLTable (10gR2 and up) or Table/XMLSequence.
In your other post you mentioned db version 10.1, so I guess we'll go with XMLSequence :
SELECT 'RTE'
       ,to_date(substr(extractvalue(x.xml_data,'/MolDocument/ValidTimeInterval/@v'),1,16),'yyyy-mm-dd"T"hh24:mi')
       ,decode(extractvalue(x2.column_value,'/MolTimeSeries/Direction/@v'),'A01','Up','Down')
       ,to_number(regexp_substr(extractvalue(x2.column_value,'/MolTimeSeries/ContractIdentification/@v'),'\d+$'))
       ,to_number(extractvalue(x2.column_value,'/MolTimeSeries/Period/Interval/EnergyPrice/@v'))
       ,sysdate
       ,null
       ,null
       ,extractvalue(x2.column_value,'/MolTimeSeries/ContractIdentification/@v')
       ,'SUBMITTED'
       ,'A96'
       ,null
       ,sysdate
FROM xml_demo x,
     table(
       xmlsequence(
         extract(x.xml_data, '/MolDocument/MolTimeSeries')
     ) x2
WHERE existsnode(x.xml_data,'/MolDocument/DocumentIdentification[@v="MOL_20100331_1500_1600"]') = 1;Please also note the use of REGEXP_SUBSTR instead of the regular SUBSTR because it didn't work for "NG_20100331_1500_6".
Hope that helps.

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.
Julie
Edited by: JulieHP on May 24, 2012 4:57 PM

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

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

How to delete parent table data even though it has child records

hi all,
How to delete parent table data even though it has child records.
ex: delete from pa_request cascade constraints;
But this command is not working .

P Prakash

ex: delete from pa_request cascade constraints;cascade constraints is DROP table option. It can't be used with DELETE. You need to delete child rows first or drop foreign keys and recreate them with ON DELETE CASCADE. Then:
delete from pa_request will automatically delete child rows. However, personally I don't like ON DELETE CASCADE. You can, by mistake, delete half of your database without even realizing it.

How to delete parent and child records?

Hi friends,
I have a Master table and a child table.
The Child table got reference key with the master table without on delete cascade.
Now, I want to delete the Master records and also it's corresponding child records.
How to do?
Thanks in adv,

Vijay

Delete the records from the child, then delete the records from the parent in two separate delete statements. I'd prefer that you create a stored procedure that does both steps.

How to delete parent and child records together ?

Hi,
I'm using Jdeveloper 11.1.2.2
I want to delete a row from a table but it is showing: Caused by: java.sql.SQLIntegrityConstraintViolationException: ORA-02292: integrity constraint (TABLE1_TL_FK1) violated - child record found.So how can I delete a Child row and table row in one method ?
I cannot access the child's VO because it is not added to the AM.
Thanks,
Nigel.

John, as usually, is right with the pointer to the documentation he pasted. Just to make sure you read it carefully, let me hoghlight an important point here:
"If the option is selected, then the composed entities do not perform the DELETE statement *on the assumption that the database ON DELETE CASCADE constraint will handle the deletion of the corresponding rows*."
So make sure the database is setup for cascade delete as otherwise you still will not succeed

How to find child records given a parent key

I have a master table which is parent for several child tables. I want to display a button to delete a record in master table. I would prefer show this button conditionally so when a master record has child records, I don't show delete button and no error is raised.
Of course I could scan every child table to find out child records, but I think must exist a generic method
How can I find out if a given parent key has child records?
Thanks in advance
Oscar
P.S: I'm using 10gR2
Edited by: user10712087 on 13/01/2009 02:31 PM

There's no magic/generic way to check that a master row has no associated detail rows. As Pavan says, you have to decide which detail tables to check, and check them using SQL as usual. (Actually, there is a quick way - you delete the row and if there are any child rows with foreign keys that don't cascade, the delete will fail; but of course you can't use this in case the delete succeeds but the user never wants to press the button).
One addition to Pavan's answer: DO NOT under any circumstances count all the records in every detail table. All you want to know is, is there at least 1 detail record in at least 1 of the tables. No need to count 100 or 1000 rows...
You can do this like this in your PL/SQL
FUNCTION check_children(p_master_id IN INTEGER) RETURN BOOLEAN
IS
CURSOR c_child1 IS
select 1 from child_table_1 where master_id = check_children.p_master_id;
CURSOR c_child2 IS
select 1 from child_table_2 where master_id = check_children.p_master_id;
-- etc for all child tables
l_rec_present integer := null;
BEGIN
    OPEN c_child_1;
    FETCH c_child_1 INTO l_rec_present;
    CLOSE c_child_1;
    IF l_rec_present i= 1 THEN
        -- there is a child in child_table_1
        RETURN TRUE;
    END IF;
    OPEN c_child_2;
    FETCH c_child_2 INTO l_rec_present;
    CLOSE c_child_2;
    IF l_rec_present i= 1 THEN
        RETURN TRUE;
    END IF;
-- etc for each child; finally, if no child found:
   RETURN FALSE;
END;This makes sure that (1) you stop as soon as you find any child, and (2) you don't get any NO_DATA_FOUND or TOO_MANY_ROWS exceptions raised.
HTH
