• the problem display of hierarchical data on table tree of ADF 11 g

  We try to display hierarchical data tree ADF tabletop.

  Thank you...

  I think that if you want to limit the list of records shown at the first level of the tree to those without a father - you'll need create a VO that this query - and then add a viewlink to the full list.
  For example by using the employees table in the HR schema, which would be something like a VO with 'where manager_id is null' for the first level, as well as a link from there to the VO used to get other levels.

• Filtered hierarchical data - previous available ancestor?

  I'm trying to find a solution to a problem with hierarchical data and the concept of the closest available ancestor – my platform is gr 10, 2 and 11 GR 2.  I give myself a few hierarchical data (in its simplest form it is in the form ID, NAME, PARENT_ID, where of the PARENT_ID since ID links).

  For example:

  with qryData like)

  Select 1 as ID, 'Bert' as NAME, to_number (null) as PARENT_ID from dual union

  Select 2 as ID, 'Brand', 1 double Union

  Select 3 as ID, 'Brenda', 1 double Union

  Select option 4 as ID, 'Mike', 3 double Union

  Select 5 as ID, 'Steve', 4 double Union

  Select 6 as ID, 'John', 2 double Union

  Select 7 as ID, 'Jo', 6 double Union

  Select ID, "Jim", 2 double Union 8

  Select 9 as ID, 'Jane', the double 7

  )

  Select q.*, sys_connect_by_path (ID, ' /') ID_PATH

  of qryData q

  Start by parent_id is null

  Connect ID PARENT_ID = prior

  /

  ID NAME PARENT_ID ID_PATH

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

  1 Bert 1

  2. Mark 1/1/2

  6 Jean 2/1/2/6

  7 Jo 6/1/2/6/7

  Jane 9 7/1/2/6/7/9

  8 Jim 2/1/2/8

  3 Brenda-1/1/3

  4 mike 3/1/3/4

  5 Steve 4/1/3/4/5

  In reality, this data set can be several thousand rows with dozens of levels of nesting, the several nodes to start without parent but especially often filtered, so some arbitrary lines are missing.  When this happens, I need to find the closest available ancestor that appears in the list. "The closest available ancestor" is closest relationship to ancestor in your family tree which still exists in the filtered list found from parent, then upward contuniing to grandparent, great-grandparent... nth grandparent grand until an ancestor is found.

  
  

  For example:

  ID NAME PARENT_ID ID_PATH AVAIL_ANCESTOR_ID

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

  1 Bert 1

  Jean 6 2 1 1/2/6

  Jim 8 2 1 1/2/8

  Jane 9 7 6 1/2/6/7/9

  Brenda 3 1 1 1/3

  Steve 5 4 3 1/3/4/5

  For example.  Who is Steve closest ancestor in the filtered list?

  Steve's family tree is: / Bert/Brenda/Mike/Steve

  Mike (ID = 4) is not in the filtered list, so we move on Brenda, what is.  Brenda, ID = 3, so ANCESTOR_ID = 3

  I have access to the original table, so that can join the list filtered to the full table, I can also ask other columns (such as ROWID, and ROWNUM, LEVEL SYS_CONNECT_ROOT) to be included in the filtered set.  I tried various methods to achieve this, but all seem to be quite poor in performance (the columns ID and PARENT_ID indexed as appropriate) or does not quite give the correct result, such as...

  1. the analysis of the ID_PATH and the treewalking on this basis and to join the list...

  Select distinct CUSTOMER_ID, regexp_substr (ID_PATH, "[^ /] +', 1, level") as ANCESTOR_ID

  of qryData

  connect regexp_substr (ID_PATH, "[^ /] +', 1, level") is not null

  2 anti-assemblage to return to the full list in order to identify the missing elements, then for those treewalking.

  3 write a function that return treewalks.

  It of a difficult problem, so someone can think a solution that works well?  Ideally, I try to find a SQL based solution?

  Hello

  It is a clever solution!  The only problem I have is that I wouldn't be able to generate "good_id_path" as part of the filtered list, filtering is not done by me and is done once the id_path is generated.  I have to join the most complete list list filtered back to generate, unless there is a tweak to do?

  I see it; You are given connect_by_results (with id_path), and that's what you have to work with, in addition to the original table.

  Here's one way:

  SELECT d.id d.name, d.parent_id, d.id_path

  MIN (a.id) DUNGEON (DENSE_RANK LAST ORDER BY a.id_path) AS avail_ancestor_id

  OF connect_by_results d

  LEFT OUTER JOIN connect_by_results has the d.id_path AS a.id_path. '/%'

  GROUP BY d.id d.name, d.parent_id, d.id_path

  ORDER BY d.id_path

  ;

  The fastest way depends on a lot of things, some may not be known until the moment of execution.  The query above could be better if the number of rows in the result set is small, but you don't know anything else about them (for example, if all have a common ancestor).

• Hierarchical data, how to aggregate over levels in hierarchical query?

  Hello
  
  I hope someone can help me.
  
  I held in a data table ("" what part was built in what other part of when when? "')
  ID parent_id build_in build_out
  1 NULL NULL NULL
  2/1 2010 2012
  3 2 2011 2013
  4 2 2013 NULL
  
  What are the parts is stored in a separate table.
  
  Now I want to know when when which part was built in the first level, in the example, I want to know that
  1 was simply a part of 1
  2 was part of 1 between 2010 and 2012
  3 was part of 1 between 2011 and 2012
  4 has never been a part of 1
  
  I tried several approaches - if there is a fixed number of levels between the types, I am interested I can do using joins and more/less (similarly as some nvl). Unfortunately this is not always the case (some parts appear on several levels).
  If I'm only interested in the parts that are never deleted, I can get by using a style of connect request and get the current configuration. But I can't seem to understand the time connecting part to the high level in such a query, or even filtering absurd combinations (like "4 in 1" in the example above). I could deal with the data recovered outside the database, but I prefer not.
  
  Is there a way to obtain the hierarchical data with an aggregate (min, max) for all levels?

  What version of Oracle you are on?

  In 11.2.x, you can use the recursive subquery factoring. Something like

  with t (id, parent_id, build_in, build_out) as (
  select 1, null, null, null from dual union all
  select 2, 1, 2010, 2012 from dual union all
  select 3, 2, 2011, 2013 from dual union all
  select 4, 2, 2013, null from dual
  )
  , c1 (root_id, id, parent_id, build_in, build_out) as (
  select id, id, parent_id, 0, 9999
  from t
  where parent_id is null
  union all
  select root_id, t.id, t.parent_id
  , greatest(nvl(t.build_in,0), nvl(b.build_in,0))
  , least(nvl(t.build_out,9999), nvl(b.build_out,9999))
  from c1 b, t
  where b.id = t.parent_id
  )
  select * from c1
  where build_in < build_out
  ;
  ROOT_ID ID    PARENT_ID  BUILD_IN  BUILD_OUT
  ------- ----- ---------- --------- ----------
  1       1                0         9999
  1       2     1          2010      2012
  1       3     2          2011      2012      
  

  With a hierarchical query by using the syntax connection, you could do something like

  select * from (
  select connect_by_root id as root, id
  , greatest(nvl(build_in,0), nvl(prior build_in,0)) as max_in, least(nvl(build_out,9999), nvl(prior build_out,9999)) as min_out
  from t
  start with parent_id is null
  connect by parent_id = prior id
  )
  where max_in < min_out
  ;
  

  but it is not powerful enough. This version compares the dates between a current and previous levels, but the recursive subquery is to compare the dates in the current level for the winners of the comparisons to the previous level. Not sure if it's an important distinction for your needs, however.

  If you are on 11.2 I advise to use the recursive subquery factoring. If this isn't the case, you can try the link by version.

• Hierarchical data model

  Hello!
  
  I need to create data model that describes hierarchical data in table t (something like this in sql: select * t log in prior t.id_parent = t.id).
  
  How to describe with JDeveloper?
  
  (Then it will be used in the table of the tree)
  JDeveloper 11.1.1.1
  
  Thank you!

  Simply create an association 1-* t.id to t.parent_id, then create viewLink based on this association.

  Hello

  CONNECTION BY ordering the release, so that the children come immediately after their parents.

  If you SEPARATE the outcomes, so we know not what order the results are in.  You can get the resutls you purely by chance, especially in a small set of data, but it is still just a coincidence.

  I think you need something like this:

  WITH distinct_data AS

  (

  SELECT DISTINCT entity

  next_entity

  FROM the data

  )

  tree AS

  (

  SELECT entity

  next_entity

  ROWNUM AS r_num

  OF distinct_data

  START WITH entity = "A".

  Entity = next_entity PRIOR CONNECTION

  )

  SELECT t.entity

  t.next_entity

  d.datum

  TREE t

  JOINING data d = d.next_entity t.next_entity

  ORDER BY r_num

  ;

  Here, the SEPARATE operation is done before CONNECT you, so you don't have to worry about destroying the order of the CONNECT BY query.

• How to remove hierarchical data?

  Hello

  I have a table with hierarchical data. I want to remove the data based on a condition, but maybe that this condition is present only in the upper hierarchy.

  In my example, I have identified by id lines and a changed_by containing the id of the row that has replaced (invalidated) this line. Of these, I want to delete data where descr in end-nodes is 'A '.

  Oracle Database 11 g Enterprise Edition Release 11.2.0.2.0 - 64 bit Production

  DROP TABLE test_del; CREATE TABLE test_del) CONSTRAINT pk_del PRIMARY KEY (id) id NUMBER changed_by NUMBER CONSTRAINT fk_del REFERENCES test_del (id) , descr VARCHAR2 (10) ) / INSERT INTO test_del (id, changed_by, descr) VALUES (3, NULL, 'A'); INSERT INTO test_del (id, changed_by, descr) VALUES (2,3, 'A'); INSERT INTO test_del (ID, changed_by, descr) VALUES (1, 2, NULL); INSERT INTO test_del (id, changed_by, descr) VALUES (6, NULL, 'A'); INSERT INTO test_del (id, changed_by, descr) VALUES (5.6, 'A'); INSERT INTO test_del (id, changed_by, descr) VALUES (10, 'B', NULL); INSERT INTO test_del (id, changed_by, descr) VALUES (9, 10, 'B'); INSERT INTO test_del (id, changed_by, descr) VALUES (8,9, 'B'); COMMIT; SELECT *. OF test_del CONNECT BY PRIOR ID = changed_by START WITH descr = 'A' changed_by AND IS NULL; ID CHANGED_BY DESCR ---------- ---------- ---------- 3            A 2 3 1          2 6            A 3 p DELETE FROM test_del WHERE the descr = "A"; ORA-02292: integrity constraint (FE. FK_DEL) violated - book of the foundling

  Of course, I get ORA-02292 in this case, but how can I write a correct statement that deletes the data displayed by the select?

  Concerning

  Marcus

  You must follow the hierarchy:

  DELETE FROM test_del

  WHERE ROWID IN)

  SELECT THE ROWID

  OF test_del

  CONNECT BY PRIOR ID = changed_by

  START WITH descr = "A".

  AND changed_by IS NULL);

• Problem (hierarchical data) resolved by using SQL

  Hi I have hierarchical data stored in a table with 3 columns
  Item1, item2, relationship
  
  relationship column defines if the element1 is parent of item2 or item1 item2 Chile
  
  I have a fourth column in the same table indicating the entire hierarchy of the family separated by colons;
  
  example: a1, a2, child then output will be a1:a2.
  
  I have tried a lot of things to do with a sql but failed and finally did using the recursive function
  
  Hoping someone can solve the problem in sql
  
  You will find examples of data to work with as well as the desired result:
  

  select 'p1' as element1, 'p2' as element2, 'parent' as relationship, 'p1' as output  from dual
  union all
  select 'p2', 'p1', 'child', 'p1:p2' from dual

• Hierarchical data in the component of the tree should not be visible

  JDeveloper version - 11.1.1.7.0

  Default in the ADF, the performance of a page with a tree component, existing hierarchies are displayed as trees.

  
  

  For my requirement the TRIE hierarchies will not be displayed and component of the tree must be empty when the page runs.

  Why not just use the executeEmptyRowSet(), as described here:

  http://www.jobinesh.com/2010/05/displaying-empty-table.html

• How to query these data as a tree structure

  Hi, how to write a query to manipulate data like tree structure report? The rules for the structure of the tree are: CORE is always a node root (level 1), level 2 is a location any is not have "/" exclude those beginning of slot with PWR. This tree structure can continue to level 3 and so on

  POSITION OF SLOT
  CORE
  F1
  FAN
  PWR/1
  1
  2
  1/0
  1/1
  1/2
  1/0/0
  1/0/1
  G1
  G4
  G4/0
  G4/1

  Output, * the order of level 2 is not necessary must begin with the F1, it can be any value of level 2

  CORE

  F1

  FAN

  PWR/1

  1

  1/0

  1/0/0

  1/0/1

  1/1

  1/2

  2

  G1

  G4

  G4/0

  G4/1

  Hello

  If you want to CONNECT BY queries, you need to know the parent of each element.  Here's a way to do it:

  WITH got_parent AS

  (

  SELECT slot_position

  CASE

  WHEN slot_position = 'CORE '.

  THEN NULL

  WHEN slot_position NOT LIKE "% / %".

  OR slot_position LIKE '% PWR '.

  THEN THE "HARD CORE".

  Of OTHER SUBSTR (slot_position

  1

  , INSTR (slot_position, ' / ', - 1)-1

  )

  END AS parent

  FROM table_x

  )

  SELECT LPAD (' ', 4 * (LEVEL - 1))

  || slot_position AS padded_slot_position

  OF got_parent

  START WITH parent IS NULL

  Parent = slot_position PRIOR CONNECTION

  ;

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

  An alternative to CONNECT BY would generate a string similar to slot_position, but including all ancestors, such as:

  CORE

  CORE/1

  CORE/1/0

  CORE, 1, 0, 0

• Loading XML file where data structure may vary

  Hi guys,.

  I'm trying to load a XML data file in an Oracle table, with some success, but it will fail to load certain lines when an element is missing. Here is an example of two rows of data:

  It is the PL/SQL that I use to try to load it:

  ) x 4;

  COMMIT;

  END;

  The first row of the loads fine, but the second row is not at all responsible. I expected he would charge what information there but with NULL values for the missing "CaseDetails" element but it charge nothing at all. If I change the data and manually add it in an element 'CaseDetails', line load. Can someone explain to me how I can get all the lines to load even if some parts are missing?

  Wrong approach altogether.

  There is no need to join via a positional predicate in this case, just use a single query:

• Merging XML but my date is so broken!

  I have data to an XML file.  It merges with my PDF template read-only.  The date from XML is formatted as follows:

  YYYY-MM-DD-06:00

  The 'extra' at the end is a zone code.  It is stored in the database like this.

  In my form, I have a read-only which displays the date above - the problem, it's that way, too!

  Anyway for me to format?  I set the type field to date and the entry value and formats - nothing works.  I use 8.0.  I tried to 'script' something, but I guess I'm pretty smart to know where these scripts would reside, nor what they should say, because I spent the day and none of my attempts gave me everything except the output above.

  Thank you!

  Hi ronini,

  You should be able to use the following database on your date field;

  date {YYYY-MM-DD?}

  Input data should match the part of YYYY-MM-DD, but the characters corresponding to questions marks will be ignored.

  On the output, you would end up with spaces where question marks.
