Recursive SQL - Parent child

Hello

In a table, I had hierarchical data (parent, child), when the mother is a child of another parent.
It is upto level4. (I mean child = > Parent1 = > Parent2 = > Grand Parent)

Child = > Parent
= A1 > B1
A2 = > B1
A3 = > B1
B1 = > B2
B2 = > B3
B3 = > B4

I need result like - each child has his parents and future parents

As:
Parent1 Parent2 Grand mother
=========================

= A1 > B1 - A1 first Parent
A1 = > b2--deuxieme Parent of A1
A1 = > b3--troisieme Parent of A1
A1 = > B4 - grandparent

Help, please. Is this possible with you connect function? I am tired of using it but I get only parents for each.

Thank you
Bobin

Hi, Blanchette,

To repeat a certain value in the first row on all connected on lines, use CONNECT_BY_ROOT

SELECT     CONNECT_BY_ROOT child   AS starting_point
,     parent
FROM     table_x
START WITH     child     = 'A1'     -- or whatever
CONNECT BY     chilD     = PRIOR parent;

Stuck on a sql query to search for records that have the same parent child records

Oracle 10 g 2 Enterprise Edition.

Hello

I'm writing a logic to find records in a parent table, who have the same values in a child table.
This is part of a larger application, but I am stuck on that part for now, so I have mocked some of the below simplified tables to capture the heart of the
the problem is that I'm stuck.
Let's say I have a responsible parent, child employee table table and there are a number of many relationships between them.
The aptly named Join_Table manages the relationship between them. If a manager can manage several employees, an employee can be managed by
many managers.

I have a feeling it's stupidly easy, but it seems to me having a bad episode of brain freeze today!

-- parent table
CREATE TABLE manager (
 id      number primary key,
 name      varchar2(100));

-- child table 
CREATE TABLE employee (
 id          number primary key,
 name      varchar2(100));

-- link table
CREATE TABLE join_table (
 manager_id          NUMBER, 
 employee_id      NUMBER,
 CONSTRAINT join_table_pk PRIMARY KEY (manager_id, employee_id),
 CONSTRAINT manager_fk FOREIGN KEY (manager_id) REFERENCES manager(id),
 CONSTRAINT employee_fk FOREIGN KEY (employee_id) REFERENCES employee(id) 
 );

-- Insert some managers
INSERT INTO manager (id, name) VALUES (1, 'John');
INSERT INTO manager (id, name) VALUES (2, 'Bob');
INSERT INTO manager (id, name) VALUES (3, 'Mary');
INSERT INTO manager (id, name) VALUES (4, 'Sue');
INSERT INTO manager (id, name) VALUES (5, 'Alan');
INSERT INTO manager (id, name) VALUES (6, 'Mike');

-- Insert some employees 
INSERT INTO employee (id, name) VALUES (101, 'Paul');
INSERT INTO employee (id, name) VALUES (102, 'Simon');
INSERT INTO employee (id, name) VALUES (103, 'Ken');
INSERT INTO employee (id, name) VALUES (104, 'Kevin');
INSERT INTO employee (id, name) VALUES (105, 'Jack');
INSERT INTO employee (id, name) VALUES (106, 'Jennifer');
INSERT INTO employee (id, name) VALUES (107, 'Tim');

-- Insert the links

INSERT INTO join_table (manager_id, employee_id) VALUES (2, 102);
INSERT INTO join_table (manager_id, employee_id) VALUES (2, 104);
INSERT INTO join_table (manager_id, employee_id) VALUES (2, 105);
-- Mary manages Jennifer, Tim
INSERT INTO join_table (manager_id, employee_id) VALUES (3, 106);
INSERT INTO join_table (manager_id, employee_id) VALUES (3, 107);
-- Sue manages Jennifer, Tim
INSERT INTO join_table (manager_id, employee_id) VALUES (4, 106);
INSERT INTO join_table (manager_id, employee_id) VALUES (4, 107);

INSERT INTO join_table (manager_id, employee_id) VALUES (5, 101);
INSERT INTO join_table (manager_id, employee_id) VALUES (5, 102);

INSERT INTO join_table (manager_id, employee_id) VALUES (5, 106);
INSERT INTO join_table (manager_id, employee_id) VALUES (5, 107);
-- Mike manages Paul, Simon, Ken
INSERT INTO join_table (manager_id, employee_id) VALUES (6, 101);
INSERT INTO join_table (manager_id, employee_id) VALUES (6, 102);
INSERT INTO join_table (manager_id, employee_id) VALUES (6, 103);

-- For sanity
CREATE UNIQUE INDEX employee_name_uidx ON employee(name);

If I ask for Manager John, so I want to find other managers who manage the exact list and even employees.
Answer should be Mike.
If I ask for Manager of Mary, the answer should be Sue.

This query will give me the list of managers who manage some of the same employees as John, but not the same employees accurate...

SELECT DISTINCT m.name AS manager
FROM manager m, join_table jt, employee e
WHERE m.id = jt.manager_id
AND jt.employee_id = e.id
AND e.id IN (
     SELECT e.id
     FROM manager m, join_table jt, employee e
     WHERE m.id = jt.manager_id
     AND jt.employee_id = e.id
     AND m.name = 'John')
ORDER BY 1;

I thought about using set operations to find managers with a list of employees less than my employees is null and where my employees under their list of employees is null. But there must be an easier way more elegant.
Any ideas?
BTW, I need to run as a batch on tables with > 20 million rows so the efficiency of queries is key.

What about...

WITH manager_list AS
(
 SELECT name,
        LTRIM(MAX(SYS_CONNECT_BY_PATH(id,','))
        KEEP (DENSE_RANK LAST ORDER BY curr),',') AS employees
 FROM   (SELECT m.name,
                e.id,
                ROW_NUMBER() OVER (PARTITION BY m.name ORDER BY e.id) AS curr,
                ROW_NUMBER() OVER (PARTITION BY m.name ORDER BY e.id) -1 AS prev
         FROM   manager m,
                join_table jt,
                employee e
  WHERE m.id           = jt.manager_id
  AND   jt.employee_id = e.id
  AND   m.name = :P_MANAGER)
  GROUP BY name
  CONNECT BY prev = PRIOR curr AND name = PRIOR name
  START WITH curr = 1
), all_list AS
(
 SELECT name,
        LTRIM(MAX(SYS_CONNECT_BY_PATH(id,','))
        KEEP (DENSE_RANK LAST ORDER BY curr),',') AS employees

                e.id,

                ROW_NUMBER() OVER (PARTITION BY m.name ORDER BY e.id) -1 AS prev
         FROM   manager m,
                join_table jt,
                employee e

  AND   jt.employee_id = e.id)

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!

parent/child relationship hirarchy

Hi everyone, consider the sample data
SELECT LFROM '1TR1Y6', NULL LTO, MID '11ZFDD', '21XHK7' double UNION ALL TID-
SELECT '1TR1YF' LFROM, LTO NULL, '11ZFDD' MI '21XHK5' TID FROM dual UNION ALL-
SELECT '1TR1X1' LFROM, LTO NULL, '11ZFDD' MI '21XHK8' TID FROM dual UNION ALL-
SELECT '1LSZX1' LFROM, LTO NULL, '11ZFDD' MI '1TR1YD' TID FROM dual UNION ALL-
SELECT LFROM "1LSZWQ", "21XHK7" LTO, MID '11ZFDD', '1TR1Y6' TID FROM dual UNION ALL-
SELECT LFROM "1LSZX2", "21XHK5" LTO, MID '11ZFDD', '1TR1YF' TID FROM dual UNION ALL-
SELECT LFROM "1LSZVG", "21XHK8" LTO, MID '11ZFDD', '1TR1X1' TID FROM dual UNION ALL-
SELECT LFROM "4LSSVG", "21XHK9" LTO "11AAA' MI '1TR1X1' TID double UNION ALL
SELECT "AAAAA" LFROM, LTO NULL, '11ABB' e, 'CCCCCC' double UNION ALL TID
SELECT "BATH" LFROM, 'CCCCCC' LTO, MID '11ABB', 'AAAAA' double UNION ALL TID
some of them have a parent/child releationship. for example, let take rank with LFROM = 1TR1Y6
1TR1Y6 (lfrom) corresponds to the fifth line with TID 1TR1Y6. TID 1TR1Y6 LTO COLUMN value corresponds to the first line TID (21XHK7)
It before these two LINES are IN a parent/child relationship.
lets take another example. LINE two WITH LFROM = 1TR1YF matches sixth RANK WITH TID 1TR1YF. the sixth LINE LTO COLUMN (21XHK5) corresponds to the SECOND TID of LINE.
Once again the parent child relationship. There are two lines that do not have the relationship of parent/child (ex. line 8)
Im trying to write a query that can partition the data in the middle column and find the parent/child relationship. the output of the above data should be
LTO LFROM MIDDLE TID FLAG
1TR1Y6 NULL 11ZFDD 21XHK7 1
1LSZWQ 21XHK7 11ZFDD 1TR1Y6 1
1TR1YF NULL 11ZFDD 21XHK5 1
1LSZX2 21XHK5 11ZFDD 1TR1YF 1
1TR1X1 NULL 11ZFDD 21XHK8 1
1LSZVG 21XHK8 11ZFDD 1TR1X1 1
1LSZX1 NULL 11ZFDD 1TR1YD 0
4LSSVG 21XHK9 11AAA 1TR1X1 0
ABDELKÉBIR 11ABB CCCCCC NULL 1
CCCCCC 11ABB AAAAA BATH 1
For simplicity, I posted the release with parent/child, side by side in the sequence. the order does not matter as long as the flag column (pull the column) is set to an appropriate value (1 if parent/child, 0 no parent/child)
the flag column value is derived from column to indicate the parent/child relationship was found.
I try using lead, the lag function but I have problem of sorting data from parent and child line could come at random order (they are not side by side).
It is therefore difficult to use lead because you don't know how many lines to carry forward.
can someone help me write a query that displays the output above

SELECT T1. LFROM,

T1. LTO,

T1. ENVIRONMENT,

T1. TID,

Hi Leo,

You have configured table of closing? http://www.rittmanmead.com/2010/11/Oracle-BI-EE-11g-parent-child-hierarchies-multiple-modeling-methods/

Also, be sure to make the changes to hierarchy in offline mode.

Fusion of data/result defines what are parent/child?
Hello:

I have seen a few examples to make a data model so that a BI report can have master-detail data. They are a set of Q1 data and a set of T2 data with a variable binding to connect the two in a parent/child relationship.

But what I need, it is actually a UNION. I have the same table on multiple instances of database and I want to show the results grouped in a single report, as if it all happened to a table. Examples of master-detail have a section defining the grouping but they group Q1 (see here)

http://blogs.Oracle.com/BIDeveloper/data_template/

and I need to regroup in a column in Q1 and Q2 to "merge" the two sets of data.

Does anyone do this?

Thank you.
If you define multiple SQL-queries/data models data sets, you can combine them into a single set of data by selecting the concatenated SQL Data Source.

Choose concatenate them box, concatenation will result in the union.

RTF again, you can use the two dataset and display as a single table.

Add an object 3d without parent/child relationship.

Hello

I have a scene of 3d picture control, I have two objects in there, but when I created the scene I had to use the add object invoke node objects in the scene, so there is a parent/child relationship between the objects, which means that if I move the parent, I also move the child object. Is there a way to create a scene with several objects without the parent/child relationship.

Thank you.

Hello, I solved it by first moving the objects and then adding them to the scene. -Luis

Imagine you remove account, Oracle must verify there is no record of the child in ACCOUNT_PARTITION, this is because as your FK is restrict the deletions (do not allow the removal if there are child records). As ACCOUNT_PARTITION. Account_id is indexed so it will be an exclusive table lock to find this, locks the table.

Another way of thinking is, imagine that you have performed the following query without and ACCOUNT_ID index:

Select *.

of ACCOUNT_PARTITION

where ACCOUNT_ID =

He SHOULD do a full table scan right? Well well, even on a deletion of the parent. It attempts to identify lines for the purpose of blocking,

As a general rule, it is always a good idea to index FKs.

Parent - child relationship constraint Unique 5.0 apex oracle

Oky so I will try to avoid duplicate values get inserted in the parent-child node.
So basically when there's a node parent (Mobile) I can't create same node with the same name.
Even for the child node, if there is a child node name there may be another named A.
Structure:
Mobile (parent) /Android (Child) /KitKat (subchild) (allowed)
Mobile/apple/ios(Now allowed Same Parent name)
Win7/Windows/win7(not allowed same child)
So a big child and the parent must be unique at any time.

create an index of single "TEST_UK" on tablename (parent_id, upper (child_name));

see this too for a case-insensitive unique constraint

Case-insensitive unique constraint

ADF Parent-child tables of rules

Hello
I use JDeveloper and ADF 12.1.3. Now, I have a set of related tables, and each of them have only a child table.
I have a jsf page master / detail for each child table. Inside it, I can insert a row in the parent table and several rows in the child table. Commit the button is clicked validate monkey for the booth tables. Link between the master (parent table) and retail (child table) is done via the partnership link and view for the user interface.
Now, here's the rule I would apply: I can't commit newly created at the table parent without at least a new inserted row in child table.
Because I have several parent-child tables in this case of use, I wanted to replace the EntityImpl class and add newly created to each parent table class, so I bussines logic in one place for this tables.
We will look and taste to the table of one of the parents (not overloaded class EntityImpl):
The Interior has generated parent EO class
@Override
{} public void beforeCommit (TransactionEvent transactionEvent)
TODO implement this method
If (! validateParentChildNumber()) {}
throw new local ("not allowed.");
}
super.beforeCommit (transactionEvent);
}
public boolean validateParentChildNumber() {}
If (getParentChild (). GetRowCount() > 0)
Returns true;
on the other
Returns false;
}
This works well. If I inserts a row in the parent table and one or more rows in the child table passes validation. But if I get a line inside the parent table and no line of children tables I'm not allowed message in my browser.
So here's where problem read. Once I'm getting now authorized message, no matter if I insert the new line of Herald, I cannot commit until what I restar my app. Why? Because now, I constantly have this message:
ORA-02291: integrity constraint (RE. FK_PAR_PAR_ID) violated - key parent not found
It's like I can't hire the existing parent row I inserted before the child missing line. Why is this happening? I should replace postChanges method and what to put in it?
Thx a lot

Yes, you should do it in all cases, but point of my post is - put this code in the method of beforeCommit() of the primary entity. Only you need to do in beforeCommit(), is to count the child related entities.

In your java master entity impl class, you will have the method which returns a RowIterator with associated children, entities, something like that

public getChildsEO() {} RowIterator

return (RowIterator)...;

}

then, just call this method in beforeCommit() and see if there is at least a child entity...

You have a point?

in the query and parent/child relationship

WITH the data AS

)
some lines have parent/child relationship and some does not. for example, the first two query (data) are link together. online, the value of lto (215ZV9) corresponds to the id value
in line 1. the value of lfrom in row1 (213NY1) corresponds to the value of online id.
the same scenario occurs in rows 3 and 4. 5th doesn't have any line which is a child. tier 5 is a single parent
I want to WRITE a query that gives the following result.
Mid id initial_date final_date
=======================================
215ZVD 215ZV9 1 January 2014 "January 5, 2014"
"215ZVD 213NY1 7 January 2014" January 6, 2014 "

"213JW7 216TVZ 24 January 2014 ' 23 January 2014"
"234YU 3IUED 26 January 2014 ' 27 January 2014"
ONLY WHEN there is a parent/child relationship, initial DATE AND follow the final data WHAT such as
FIRST date of deadline DATE
< Mdate > < EDate > - for child
< SDate > < MEDate > - for parent
WHEN there is no relationship of parent/child (e.g. ONLY a parent ROW) THEN
FIRST date of deadline DATE
< SDate > < EDate-> parent
can someone help me write a query for the above output

with tt AS

(SELECT a.*,

ROW_NUMBER () ON LV (MIDDLE ORDER BY SDATE PARTITION),

CASE

WHEN ID = NVL (ADVANCE (lto, 1) OVER (PARTITION BY Middle ORDER BY sdate), LAG (lfrom) OVER (ORDER BY sdate Middle PARTITION))

THEN 1

END flg

DATA one

)

SELECT THE MIDDLE,

ID,

CASE

WHEN flg IS NOT NULL

THEN

CASE

WHAT LV = 1

THEN SDATE

WHAT LV = 2

THEN mDATE

Of ANOTHER sdate

END INITIALDATE

CASE

THEN

CASE

WHAT LV = 1

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.

Navigation in Parent child Hiearachy is a bug in OBIEE 11.1.1.6?
Hi all

Look in one of my previous posts

OBIEE 11g - Navigation in the Parent child hierarchy does not

One of my friends Ram told me that it is a Bug of Oracle in 11.1.1.6. It's that I just wanted to know if someone has faced the same problem and this was reported as a bug in Oracle. Unfortunately, I do not have the privileges to log a bug or review the information in bug, can someone please provide any information on that?

Thank you
Ronny
Hello

This problem is fixed in Version 11.1.1.7.0 Obiee (here next year released Q1: currently his patch not published)

Thank you
