Child parent multi in an AppModuleDataControl

Hello

I am creating an application requiring several (5 +) level of relationship parent/child in an AppModuleDataControl...

(using the tutorial following as an example: http://docs.oracle.com/cd/E37547_01/tutorials/tut_rich_app/tut_rich_app_2.html)

Is this something that is possible?

Thanks in advance

User, please tell us your jdev version.

Yes, it is possible. Where do you see a problem? If your data mode has that kind of relationship you build (or if foreign keys are configured in the db you get automatically). a sample until lever 3: JDeveloper & amp; ADF: Several Tables cascading | JDev & amp; Goodies ADF

Perfected request based on child parents ask completion status FND_REQUEST. SUBMIT_REQUEST, sub_request TRUE

Hi gurus,
We have a requirement where we need to request id of parent filled at the request of the child and the ability to set the parent, status of the request based on the completion status request child.
I use FND_REQUEST. SUBMIT_REQUEST with sub_request as TRUE to submit an application for the child of the mother's request.
I followed the code in ' Sample Code for a simultaneous program that submits a request of the child (Doc ID 1616185.1) '
After using the code, request parent child is is perfectly filled. But am not able to set the status of the parent program based on the completion status of the children's program.
I tried to use wait_for_request, while loop and same goto to achieve. nothing works and if I use the program of these children goes inactive, Manager of no..
Any help is greatly appreciated.
Best regards

Hi all

I raised a Bug with the development team and they have confirmed that we can not get the request completion status child when using fnd_request.submit_request with sub_request as TRUE.

Thus, it is not possible to set the completion status of the request based on the State of completion request child parent.

Hope this helps others...

expdp/impdp: constraints in the child-Parent relationship

Hello

I have a table parent1 and child1, child2 and chld3 tables have foreign key created on this parent1.

Now, I want to do a delete on parent1. But as the number of records is very high on parent1, we go with expdp / impdp with option querry.

I took the expdp parent1 level query. Now I dropped parent1 with option of cascade constraints and all foreign keys created by child1, 2 and 3 that parent1 references are automatically deleted.

Now, if I have the impdp to the query of fire level dump file, are these foreign key constraints will be created automatically on child1, 2 and 3 or I need to manually recreate it?

Kind regards

ANU

Hello
The CF will not be in the dumpfile - see the code example below where I generate a sqlfile following pretty much the process that you would have done. This is because FK belongs to the DDL for the child table not the parent.

I also want to add/change/remove the data from the two tables.

Could you please guide me to some tutorial so that I can make the features mentioned above as I'm new to ADF.

Missing child Parent in a merge WebHelp TOC TOC (RoboHTML Version 9.0.2.271)

Years, I have used Mr Grainge excellent document for fusion Help RoboHTML 8 to produce a WebHelp TOC. Recently I discovered that a child was left out of the merged TOC. Following the instructions (merging the child in the parent TOC, by generating the parent and generating the child) the child does not appear in the parent TOC. I get all the other children, but not the new.
Any suggestions?

Have you tried to rebuild all to a new location?

Calculation of average in the child-parent relationship
Hello

Oracle database version: 11.2.0.1.0

Currently I'm having a problem of query to calculate the average value. Using the usual average query does not get the result I'm looking for. Because I'm not good with English, I will try to explain for example instead.

Data table
```
COD_A     COD_B     SALES     QTY     PRICE
0000302     00003               6.09
0000302     00003               11.7
0000304     00003               14.08
0000306     00003               8.87
0000306     00003     3105     510     4.63
0000306     00003               4.65
0000308     00003     18091     1456     12.43
```
If I try to calculate the average price of COD_A, I have the correct answer, as expected.
```
SELECT COD_A, SUM(SALES), SUM(QTY), AVG(PRICE) FROM VDATATABLE GROUP BY COD_A ORDER BY 1;
```
Average price per COD_A
```
COD_A     SUM(SALES)     SUM(QTY)     AVG(PRICE)
0000302                                8.895
0000304                           14.08
0000306     3105         510                6.05
0000308     18091        1456              12.43
```
--------------

If I try to calculate the average price of COD_B, I don't have my expected result.
```
SELECT COD_B, SUM(SALES), SUM(QTY), AVG(PRICE) FROM VDATATABLE GROUP BY COD_B ORDER BY 1;
```
Average price per COD_B (1)
```
COD_B     SUM(SALES)     SUM(QTY)     AVG(PRICE)
00003     21196             1966              8.92142857142857
```
The result I'm looking for is
```
WITH W1 AS
(SELECT COD_B, SUM(SALES) SALES, SUM(QTY) QTY, AVG(PRICE) PRICE FROM VDATATABLE GROUP BY COD_A,COD_B)
SELECT COD_B, SUM(SALES), SUM(QTY), AVG(PRICE) FROM W1 GROUP BY COD_B;
```
Average price of COD_B (2)
```
COD_B     SUM(SALES)     SUM(QTY)     AVG(PRICE)
00003     21196              1966         10.36375
```
---------

So, the way I want to calculate the average price is the average of the lower child attribute and continue the average to its parent attribute. Currently I can get the result by using the clause, but the hierarchy available not only stops at COD_B, there is more (e.g. COD_C, COD_D, so on), so the foregoing WITH the query "seems" to be inflexible. If I want to ask the COD_C aggregation, I might have to put another COMPONENT in the query.

So I was wondering is there any other better method to get the result I want? Something more dynamic as a recursive function or integrated maybe?

Thank you

Hello

Whenever you have questions, please post CREATE TABLE and INSERT statements for your sample data.
Always tell what version of Oracle you are using. Don't say something vague, like "11g" in a label where it is easy to miss. Tell exactly what version you have in the body of the message. For example "I'm using Oracle 11.1.0.7.0.

If you have N levels in the hierarchy, then using subqueries N-1, as you already do, might be the best way.

If you use Oracle 11.2, you may be able to obtain these results by using a WITH recursive clause.

Here's another approach to obtain the results desired with a hierarchy of level 2:
```
WITH     got_cnt          AS
(
     SELECT     cod_a, cod_b, sales, qty, price
     ,     COUNT (*) OVER (PARTITION BY cod_a, cod_b)     AS cnt
     FROM     data
)
SELECT       cod_b
,       SUM (sales)               AS sum_sales
,       SUM (qty)                  AS sum_qty
,       SUM (price / cnt)
       / COUNT (DISTINCT cod_a)     AS avg_price
FROM       got_cnt
GROUP BY  cod_b
;
```
I think you can do this job for any number of levels without adding another subquery for all levels. You may need to add expressions to COUNT more for all levels, and the query only works for a fixed number of levels.

How to find records given a child parent key
I have a main table that is parent for several children tables. I want to display a button to delete a record in the primary table. I would have preferred to see the this key conditionally so when a master record's child records, I don't show button Delete and no error is raised.
Of course I could scan each child table to find the child records, but I think that must be a generic method

How can I tell if a given parent key has child records?

Thanks in advance
Oscar
PS: I use 10 gr 2

There is no magic/generic way to verify that a main line has no associated detail line. As says Pavan, you must decide which detail the tables to check and them using SQL as usual. (In fact, there is a quick way - you remove the line if there is no child rows with foreign keys which is not cascade, the delete will fail; but of course you can't use this in case the deletion succeeds and the user never wants to push the button).

An addition to the Pavan response: DO NOT under any circumstances to count all records in the table of every detail. Everything you want to know is, is it at least 1 record retail at least 1 tables. No need to count the lines 100 or 1000...

You can do it 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 made sure that (1) you stop once you find any child, and (2) you get all NO_DATA_FOUND and TOO_MANY_ROWS exceptions thrown.

Synchronizing with the database for the relationship child parent - several associations is auto created

JDeveloper version - 11.1.1.7.0

I created a table say 'table ' have a primary key. Created a new ADF application and using business components of Table added table at my request.

I then created another table in the database say 'TableChild' have a foreign key reference to a field in thetable '. In my application, I added the TableChild using business components of Table option.

Associations and/or display of the links between the 2 tables will be created. Also tried to synchronized the OS using the option "Synchronize with the database", but it still reflects. Is it possible to automatically generate associations and post links and/or when a child table is added to the model.

He is a well-known but in 11.1.1.7.0

Check what to do with duplicate association which has all the information

Get the parent-child hierarchy of column delimited

I've been on this forum once before, and someone helped me, so I hope I can get help again!
4-15-5987');
Thus, the hierarchy is divided on the hyphen. first parent being 4245, then the next value is-4 (including the hyphen) and what follows is - 1, for example
```
CREATE TABLE REGEXTEST
  ( ITEM VARCHAR(20)); 

  INSERT INTO REGEXTEST (ITEM) VALUES ('4245-4');
  INSERT INTO REGEXTEST (ITEM) VALUES ('4245-4-1');
  INSERT INTO REGEXTEST (ITEM) VALUES ('4245-4-10');
  INSERT INTO REGEXTEST (ITEM) VALUES ('4245-4-11');
  INSERT INTO REGEXTEST (ITEM) VALUES ('4245-4-12');
  INSERT INTO REGEXTEST (ITEM) VALUES ('4245-4-13');
  INSERT INTO REGEXTEST (ITEM) VALUES ('4245-4-14');
  INSERT INTO REGEXTEST (ITEM) VALUES ('4245-4-15');
  INSERT INTO REGEXTEST (ITEM) VALUES ('4245-4-15-59A7');
  INSERT INTO REGEXTEST (ITEM) VALUES ('4245-4-15-59D7');
  INSERT INTO REGEXTEST (ITEM) VALUES ('4245-4-15-59F7');
  INSERT INTO REGEXTEST (ITEM) VALUES ('4245-
```
I have to be able to bind-1, -4, 4245. Perhaps the simplest is to build a new table with a primary key where it is assigned the id of the parent to the child.
I just can't understand how to divide the individual elements and maintain the hierarchy. As previously mentioned, someone helped me with another part of the problem before where I needed to maintain the entire path of each child with the following query:
```
select  nvl(prior item,item) parent,
        nvl2(prior item,item,null) child
  from  REGEXTEST
  connect by substr(item,1,instr(item,'-',-1) - 1) = prior item
  order by child,parent
```
Now, if I could extrapolate that into a new table:
```
CREATE TABLE FileHierarchy
(ItemID INT NOT NULL PRIMARY KEY,
ItemName varchar(50) NOT NULL,
ParentID INT NULL);
```
ItemName is the 4245 or - 4 or - 1 (only) - Yes, including the hyphen.
The ID of the parent-1 would be the ID-4, etc...
Thank you very much in advance!

I have a table that contains the parent and child information. I need to make a request to get the parents of each book of the child table. I tried to write the query but does not get the expected results. Please help me.
Table: relationship
Parent of the child
102 101
103 102
104 103
106 105
107 106
109 108
110 109
Output:
Expected child
102 101
103 102; 101
104 103, 102, 101
106 105
107 106; 105
109 108
110 109
Thank you very much

Why do you want to

Expected child

----- ---------------

110 109

Instead of

Expected child

----- ---------------

110 109; 108

?

You may want something like this:

CONNECT_BY_ROOT SELECT AS children

SYS_CONNECT_BY_PATH (parent, ';') AS expected_output

FROM table_x

WHERE CONNECT_BY_ISLEAF = 1

CONNECT BY child = parent PRIOR

;

If you would care to post CREATE TABLE and INSERT statements for your sample data, and then I could test this.

Hierarchy parent child scenario
Hi friends,

Im just working on the parent-child hierarchy by using the link below with the sample data.

http://www.Oracle.com/WebFolder/technetwork/tutorials/OBE/FMW/bi/bi11115/biadmin11g_02/biadmin11g.htm_

I tried to implement the same hierarchy using my local data instead of referring to the sample data.

I have a query that returns the Manager as well as the position of the employee at the employee below
```
select distinct papf.person_id,  papf.full_name "Employee Name", supf.person_id "Manager Id", supf.full_name "Manager Name", pj.name "Position Name"
from per_all_people_f papf, per_all_assignments_f paaf, per_all_people_f supf, per_jobs pj
where papf.person_id = paaf.person_id and supf.person_id = paaf.supervisor_id and paaf.job_id = pj.job_id
and trunc(sysdate) between paaf.effective_start_date and paaf.effective_end_date and 
trunc(sysdate) between papf.effective_start_date and papf.effective_end_date
```
Im looking forward to implement the same result in my BI with a parent-child hierarchy.

Since then, I imported three tables to my physical layer
```
per_all_people_f------------Dimension
per_all_assignments_f-----Fact
per_jobs---------------------Dimension
```
For the creation of parent-child in BI, we need to have a table of separate Parent child which consist of four columns like ancestorkey, memberkey, distance, sheet.

In the column above, I can understand the meaning as
```
For Ancestorkey-->Managerid
Memberkey------->Employeeid
```
But I could not the meaning of the column distance as the meaning suggest, as a distance b/w the two column of the worksheet in the sense suggest as one sheet What leaf member it refers.

I also have the link below then too could not get the feel for it

http://www.rittmanmead.com/2010/08/Oracle-BI-EE-11g-Parent-Child-Hierarchies-Differing-Aggregations/+.

How do I train the child parent table for the BI of my three tables above in the HRMS.

Thank you

Kind regards

Hi friends,

I think I found a link to

http://prasadmadhasi.com/2011/11/15/hierarchies-parent-child-hierarchy-in-OBIEE-11g/

Let me try this and will update accordingly.

Thanks for your point of view.

Kind regards

composite unique constraint on the values of parent and child?

Is it possible to have a composite unique constraint that contains the values of the child elements? The example below has the "child" elements are offline, but it's preferred, but optional, I know that you can have a unique constraint in the set of tables without using a reference table that contains the constraint and the two columns. How xdb manages this requirement?

permit:

<parent ID="1">
   <child><name>test1</name></child>
   <child><name>test2</name></child>
</parent>
<parent ID="2">
   <child><name>test1</name></child>
   <child><name>test2</name></child>
</parent>

not allowed:

<parent ID="1">
   <child><name>test1</name></child>
   <child><name>test1</name></child>
</parent>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" 
           xmlns:xdb="http://xmlns.oracle.com/xdb"
           xdb:storeVarrayAsTable="true"
           elementFormDefault="qualified">
    
    <xs:element name="parent" type="Parent_T"
        xdb:columnProps="CONSTRAINT parent_pkey PRIMARY KEY (XMLDATA.ID)"
        xdb:defaultTable="PARENT"/>

    <xs:complexType name="Parent_T" xdb:SQLType="PARENT_T" xdb:maintainDOM="false">
        <xs:sequence>
            <xs:element name="child" type="Child_T" minOccurs="1" maxOccurs="unbounded" xdb:SQLName="CHILD"
                      xdb:SQLInline="false" xdb:defaultTable="CHILD" "/>
        </xs:sequence>
        <xs:attribute name="ID" xdb:SQLName="ID" use="required" />
    </xs:complexType>
    
    <xs:complexType name="Child_T" xdb:SQLType="CHILD_T">
       <xs:sequence>
         <xs:element name="name" type="xs:string" xdb:SQLName="NAME"/>
       </xs:sequence>
     </xs:complexType>     
</xs:schema>

xdb:columnProps = "CONSTRAINT parent_pkey PRIMARY KEY (XMLDATA.ID), * UNIQUE (XMLDATA.» "Child.Name) *" triggers the non-existent attribute

A possible solution would be to copy the value of the primary key parent of the child element, then I could create a composite unique constraint using only the values of the child. However, I have this same requirement elsewhere in my lowest nested schema, and it can become messy / bad design with cascading of all primary keys on the schema. For example, I have a recursive element in which two attributes must be unique only within the parent company:

<parent id="1">
   <child a="1" b="1">
      <child a="1" b="2">
         <child a="1" b="1" /> *not allowed
      </child>
   </child>
   <child a="1" b="2" /> *not allowed
</parent>

Possible solution:

<child a="1" b="2" parent_id="1" />
<xs:complexType name="Child_T>
   <xs:sequence>
      <xs:element name="child" xsd:SQLInline="false" xsd:columnProps="UNIQUE(XMLDATA.a,XMLDATA.b,XMLDATA.parent_id)" minOccurs="0" maxOccurs="unbounded" type="Child_T">
   </xs:sequence>
   </xs:element
</xs:complexType>

Is there a better design?
