  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.

• 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!

• Need your help to identify the parent nodes

  Hello Experts,

  I came across a requirement for a company where I get it either parent or child.

  In detail:

  Each node in the hierarchy was built as branch nodes and I see not all leaf nodes and the target system referencing the Core.Leaf property to determine if it is a parent or child, now, I have to change the process so that

  If the node does not have children even though he is a member, then the property should give as the child of another parent.

  Please help me with this requirement.

  Please let me know if you need other details as well, as I am now learning DRM so there may be some gorgonians in my language

  There is a function called IsBottomNode(), you can take advantage of this feature to your needs.

• How to write a hierarchical query so that only the child nodes are displayed?

  Hi all

  I have a hierarchical query that I use in an area of tree demand APEX and there are nodes that have no children and I am trying to find a way to not display these nodes. Essentially if the user does not have to develop a lot of knots to know that nothing exists at the most detailed level.

  The data are based on the Oracle Fusion FND tables but for example purposes here is enough data to illustrate my question:

  
  

  create table APPL_TAXONOMY_HIERARCHY (SOURCE_MODULE_ID varchar2(30), TARGET_MODULE_ID varchar2(30));
  create table APPL_TAXONOMY_TL (module_id varchar2(30), description varchar2(100), user_module_name varchar2(30), language varchar2(5));
  create table APPL_TAXONOMY (MODULE_ID    varchar2(30),    MODULE_NAME    varchar2(30), MODULE_TYPE varchar2(10),    MODULE_KEY varchar2(30));
  create table TABLES (table_name varchar2(30), module_key varchar2(30));
  
  

  insert into APPL_TAXONOMY_TL values ('1', null, 'Oracle Fusion', 'US' );
  insert into APPL_TAXONOMY_TL values ('2', null, 'Financials', 'US' );
  insert into APPL_TAXONOMY_TL values ('3', null, 'Human Resources', 'US' );
  insert into APPL_TAXONOMY_TL values ('20', null, 'Accounts Payable', 'US' );
  insert into APPL_TAXONOMY_TL values ('10', null, 'General Ledger', 'US' );
  
  insert into APPL_TAXONOMY_HIERARCHY values ('1', 'DDDDDDDD');
  insert into APPL_TAXONOMY_HIERARCHY values ('2', '1');
  insert into APPL_TAXONOMY_HIERARCHY values ('3', '1');
  insert into APPL_TAXONOMY_HIERARCHY values ('4', '1');
  insert into APPL_TAXONOMY_HIERARCHY values ('10', '2');
  insert into APPL_TAXONOMY_HIERARCHY values ('20', '2');

  insert into APPL_TAXONOMY values ('20', 'AP', 'APP', 'AP');
  
  insert into tables values ('GL_JE_SOURCES_TL','GL');
  insert into tables values ('GL_JE_CATEGORIES','GL');
  

  My hierarchical query is as follows:

  with MODULES as
  (
  SELECT h.source_module_id, b.user_module_name, h.target_module_id
        FROM APPL_TAXONOMY_HIERARCHY H,
        APPL_TAXONOMY_TL B,
  APPL_TAXONOMY VL
  where H.source_module_id = b.module_id
  and b.module_id = vl.module_id
  and vl.module_type not in ('PAGE', 'LBA')
  UNION ALL
  select distinct table_name, table_name,  regexp_substr(table_name,'[^_]+',1,1) 
  from TABLES --needed as a link between TABLES and APPL_TAXONOMY
  union all
  select module_key as source_module_id, module_name as user_module_name, module_id as target_module_id  from appl_taxonomy VL where VL.module_type = 'APP')

        START WITH source_module_id = '1'
        CONNECT BY PRIOR source_module_id = target_module_id

  In Oracle APEX, this gives a tree with the appropriate data, you can see here:

  https://Apex.Oracle.com/pls/Apex/f?p=32581:29 (username: guest, pw: app_1000);

  The SQL of the query results are:

  STATUS

  TITLE LEVEL

  VALUE

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

  	1	1 oracle Fusion	Oracle Fusion
  	-1	2 financial tables	Financials
  	-1	3 accounts payable	Accounts payable
  	0	4 AP	AP
  	-1	General Accounting 3	General Accounting
  	-1	4 GL	GL
  	0	5 GL_JE_CATEGORIES	GL_JE_CATEGORIES
  	0	5 GL_JE_SOURCES_TL	GL_JE_SOURCES_TL
  	0	2 human resources	Human resources

  The lowest level is the name of the table to level 5. HR is not any level under level 2, in the same way, "AP" (level 4) has nothing below, i.e. no level 5 and that's why I don't want to show these nodes. Is this possible with the above query?

  Thanks in advance for your suggestions!

  Hello

  The following query will include only the nodes of level = 5 and their ancestors (or descendants):

  WITH modules LIKE

  (

  SELECT h.source_module_id

  b.user_module_name AS the title

  h.target_module_id

  To appl_taxonomy_hierarchy:

  appl_taxonomy_tl b

  appl_taxonomy vl

  WHERE h.source_module_id = b.module_id

  AND b.module_id = vl.module_id

  AND vl.module_type NOT IN ('PAGE', "LBA")

  UNION ALL

  SELECT DISTINCT

  table-name

  table_name

  , REGEXP_SUBSTR (table_name, ' [^ _] +')

  From the tables - required as a link between the TABLES and APPL_TAXONOMY

  UNION ALL

  SELECT module_key AS source_module_id

  AS user_module_name module_name

  module_id AS target_module_id

  Of appl_taxonomy vl

  WHERE vl.module_type = 'APP '.

  )

  connect_by_results AS

  (

  SELECT THE CHECK BOX

  WHEN CONNECT_BY_ISLEAF = 1 THEN 0

  WHEN LEVEL = 1 THEN 1

  OF ANOTHER-1

  The END as status

  LEVEL AS lvl

  title

  -, NULL AS icon

  , LTRIM (title, "") AS the value

  -, NULL as ToolTip

  -, Link AS NULL

  source_module_id

  SYS_CONNECT_BY_PATH (source_module_id - or something unique

  , ' ~' - or anything else that may occur in the unique key

  ) || ' ~' AS the path

  ROWNUM AS sort_key

  Modules

  START WITH source_module_id = '1'

  CONNECT BY PRIOR Source_module_id = target_module_id

  Brothers and SŒURS of ORDER BY title

  )

  SELECT the status, lvl, title, value

  -, icon, tooltip, link

  OF connect_by_results m

  WHEN THERE IS)

  SELECT 1

  OF connect_by_results

  WHERE the lvl = 5

  AND the path AS ' % ~' | m.source_module_id

  || '~%'

  )

  ORDER BY sort_key

  ;

  You may notice that subqueries modules and the connect_by_results are essentially what you've posted originally.  What was the main request is now called connect_by_results, and it has a couple of additional columns that are necessary in the new main request or the EXISTS subquery.

  However, I am suspicious of the 'magic number' 5.  Could you have a situation where the sheets you are interested in can be a different levels (for example, some level = 5 and then some, into another branch of the tree, at the LEVEL = 6, or 7 or 4)?  If so, post an example.  You have need of a Query of Yo-Yo, where you do a bottom-up CONNECT BY query to get the universe of interest, and then make a descendant CONNECT BY query on this set of results.

• Get the parent (paragraph) of the text

  Hi all

  I met a problem and can't seem to find the solution myself. It's like this:

  Let's say you have a story with two paragraphs. A paragraph has 'Hello' in it and the other a 'world' in as text.

  You can select e.g. 'Hello', then click on a button, and then after clicking on the button change for example "Hello".

  So you have a paragraph with "Greetings" and the other with the "world".

  Now, I have the following code I need to change:

  selectedContent var = app.selection [0] .silence; It's selection, "Hello".

  var contentToChange = app.selection [0] .parent; This is the story.

  I want to contentToChange be the paragraph in the text.

  .parent Gets the story, so everything disappears and becomes just "Hello".

  Tried a lot of things, but impossible to find the solution (what should I use instead of 'parent' to get the paragraph).

  Can anyone help please, thank you in advance

  Greetings

  contentToChange = app.selection [0] .paragraphs [0]

• Table tree - Select All child nodes at the same time when the Parent node is selected.

  Hi all

  I am relatively new to ADF and JDeveloper, and so I hit a problem I can't deny.

  I have a tree table that looks like the following...

  1 status | Name | Employee ID

  -> Status 2. Name | Employee ID | etc. | etc.

  -> 3 status. Name | Employee ID | etc. | etc. | etc.

  I want to do is when I select the node from top of the line/parent (line 1) page I would like child nodes (lines 2 and 3) to choose from in the same mouse clicks.

  In the end I will be citing a listener of the property on a button, once the selection was made, to change the value of the 'Status' column in all three levels that have been selected.

  NB. each level in the tree above is derived from 3 views distinct, who are joined on the employee ID.

  Thanks in advance for your help and your advice.

  Kind regards

  Jamie.
