• Help of query output: display self-referential table

  Hello
  
  I'm trying to display a table referring to itself in a cfoutput. I'll start by showing some of the data in the table.
  
  There are only 3 columns, pl_id (auto increment id pri - keys), pl_name and pl_parent_id (0 if it is a parent, otherwise it is the value of pl_id for the parent).
  
  pl_id pl_name pl_parent_id
  1 country 0
  Food 2 0
  3. WE 1
  4 Japan 1
  5 Burger 2
  6 Idaho 3
  Florida 7 3
  8 cheese 2
  
  What I am trying to output is something like this:
  Country - United States - Idaho (3 levels here) or
  Country - United States - Florida (or if there are only 2 levels as the following line)
  Food - cheese
  
  I tried using a cfoutput with a cfloop as well as grouping but does not have a chance. Could someone clear my head on this one?
  
  Thank you very much
  
  Joe
  
  PS. Adobe should really use a police fixed-width for these forums, it is impossible to align the table info!

  Well Yes, who do. After you have changed a little this puppy will be completed. Thanks to the people who reduced to chips in this thread.

• Firefox fails to submit form self-referential unless I wait 20-30 seconds.

  EDIT: (the solution ended up being, against all odds, that everything was actually perfectly fine. He has been the host - which was ruin it. Note to everyone who comes through this: GoDaddy is terrible for hosting. The same files, downloaded to real Web host like SourceForge, work perfectly well. What GoDaddy can possibly fail, I can't even imagine.)

  I have created a self-referential form (POST method) in PHP for lead a user through the complicated branching calculation process. I load the PHP in Firefox 3.6 and it is indeed and I do the first communication and which works very well. But if I do another presentation quickly (within seconds), instead of working, he submits to itself with no field, so I will be the first return page once again, and no matter what I do, he keeps submitting with no field. If I can not recharge the original PHP file by POST and redo the first presentation, the first communication works again and the second fails again.

  However, if I do the first presentation and then sit there doing absolutely nothing for maybe 20-30 seconds and then do the second presentation, this works perfectly well. If I wait one more time, the third presentation works; otherwise, he says as the first, with no field and messes.

  I tried with and without the HTTP headers to prevent caching, without effect.

  Any ideas what's happening?

  Edit: (And, to be clear, if I change my POST GET method method, it works perfectly every time. But given the data appear in the URL is confusing and problematic for users, but also seriously complicate the process of bookmarking if the user decides to the computing environment to make a bookmark. The bookmark must be at the beginning of the calculation, not in the Middle, because the calculation is sensitive to time, so the old data are useless and should not be replicated.)

• Select the data in a table and update in another table

  Dear experts,

  create the table TB_ENCRYPT

  (

  Identification number,

  Varchar2 (200) KEY

  );

  INSERT INTO TB_ENCRYPT VALUES(1,'HJUVHDUIFBSDGVU');

  SELECT * FROM TB_ENCRYPT;

  1 HJUVHDUIFBSDGVU

  create TABLE users)

  username, NUMBER of

  password VARCHAR2 (200)

  );

  Insert users

  values (1, 123 # "")

  Insert users

  values (2, 456 #')

  Select * from users;

  1 123 #.

  # 2 456

  I want to select the data KEY for table TB_ENCRYPT column and update in the column of tables for the respective key user password

  TB_ENCRYPT table contains only a single key value. Comparing this key, I want to update the old value of the key to the new value.

  For encryption and decryption I followed the java class method.no is worried about that.

  create or replace

  PACKAGE PCK_ENC AUTHID CURRENT_USER AS

  FUNCTION DECRYPT (VARCHAR arg0, arg1 VARCHAR) AS VARCHAR BACK LANGUAGE JAVA NAME 'Encrclass.decrypt (java.lang.String, java.lang.String) return java.lang.String ';

  FUNCTION ENCRYPT (VARCHAR arg0, arg1 VARCHAR) AS VARCHAR BACK LANGUAGE JAVA NAME 'Encrclass.encrypt (java.lang.String, java.lang.String) return java.lang.String ';

  END;

  SELECT PCK_ENC. ENCRYPT('1234','HJUVHDUIFBSDGVU') FROM DUAL;

  HERE,

  1234 - is the password of the users table column data

  HJUVHDUIFBSDGVU - represents the key of table TB_ENCRYPT column data.

  Comparing this key, I want to update the old value of the key to the new value.

  I tried with this method

  declare

  cursor c1 is

  Select the key

  of TB_ENCRYPT

  where id = 1

  update the id;

  Start

  for c1_rec looping c1

  update users

  password is PCK_ENC. Encrypt (Password, Key)

  the location being c1;

  commit;

  end loop;

  end;

  /

  Help, please

  You can use the MERGE statement.

  merge into users
  using tb_encrypt
     on (id = userid)
    when matched then
        update set password = PCK_ENC.ENCRYPT(password,key);
  

  And why you encrypt your password. This isn't a good idea. Just password hash.

• How to select all text in a table with a single click cell?

  How to select all text in a table with a single click cell? I use TextField.selectAll () when you implement a table cell factory. But when I select a line with a single click, then a click on a table cell again: see the result image

  The text in the table cell is not all selected. What I simply selects all the text in a table cell when there is a click on it. How to realize that? Thank you

• self-referential attribute: how to set the value if it is /inconnu

  Hello
  
  I get the following error while checking the logic loop:
  
  self-referential attribute: b5@Rules_test_doc
  number of rules in this loop: 3
  number of attributes in the string in loop: 3
  number of links in the chain loop: 0
  
  The rules engine will begin with information from a database.
  
  My requirement is to define a value for the attribute (X) = 'ABC' if (X) is null and (Y) 0
  (10.4 null is represented by unknown)

  You will need to have an intermediate field here to achieve. It's certainly a logic in terms of the OPA loop, as you try to use X to prove the X.
  You need to do to resolve the issue:

  attribute (X) = 'ABC' if (X_input) is null and (Y) 0

  Or for an example of "true":

  Office of the person:
  ------------------------------------
  "london" | Office provided the person is currently unknown
  the person is provided to the office. in the opposite case

  So if no office treatment was provided by the database (i.e. ' null') it is by default effectively in London.
  You can then use "Office of transformation of the person" as normal during menstruation, confident that he should never be unknown.

  See you soon,.

• cannot select data in a nested table?

  why we cannot select data in a nested table?

  /
  

  It also isn't a such thing as a ' + nested table + "-despite what the documentation calls them. The CORRECT term is the table. Since the dawn of programming. And called 'paintings' in many languages of programming and data structure theory ever since.

  In Oracle, the term "table" has a very precise meaning. A table in PL/SQL language nothing BUT a table at all. A completely different data structure that does not have the characteristics of an Oracle table.

  The code you wrote is also dangerous. If there are 100,000 rows in this table, you will copy all 100,000 rows in a PL/SQL table - that resides in the memory of the very expensive server called the PGA (process private memory). You can cause a serious impact on the memory of the server with this approach of poor quality - I saw such a code crashing the production servers.

  So let's not terminology. Is the wrong approach. Code is wrong.

  So why not rather tell us what you're doing, or trying to understand, instead?

• Several feature selection to row in the table

  Hello
  
  I have a group with the style of layout table and I want to set the the "multiple" generated table rowSelection property but it seems there is no way to do unless you are using the group as LOV, which is not desirable for me to JHs. The following code shows how to set this property in tableGroup.vm:
  
  #if (! ($JHS.current.group.useAsLov & & $JHS.current.group.multiSelect))
  selectionListener = "#{#BINDINGS_TABLE (). collectionModel.makeCurrent}.
  rowSelection = 'single '.
  #if (! $JHS.current.group.useAsLov)
  selectedRowKeys = ' #{#TABLE_BEAN () .selectedRow} ".
  #end
  #else
  rowSelection = "multiple".
  selectedRowKeys = ' #{#LOV_PAGE_BEAN () .selectedRowKeySet} ".
  selectionListener = "#{#LOV_PAGE_BEAN () .selectionListener}".
  #end
  
  Is there a reason for not allowing to have several feature selection of line in the table when it is not in mode LOV?
  
  Thank you
  Will do

  Will do,

  No, but if you want to have multiple selection, there is typically a custom action that you want to apply to selected lines, which cannot be defined in the Jheadstart Application definition editor.
  However, it is perfectly well use a custom template tableGroup.vm and allow multiple selection.

  Hello

  This seems an expected behavior of the skin of the merger.
  The selected line inactive thoroughly clear yellow that is hard to recognize on some screens.

  solution:
  create a custom look (extend the skin of 'fusion') and create css, like this:
  AF | : the table-row data: selected: inactive af | : given the column cell.
  AF | : the table-row data: selected: inactive af | column: banded-data-cell
  {
  background-color: blue;
  }

• [JS] select multiple rows in a table

  Hi guys,.

  Is it possible to select several lines in a table? If I pass a reference table of the lines to the app.select () method, it fails.

  For that which is ok, but not for two or more. The lines are next to that them not chnge a thing.

  var t = ....tables[0] //a given reference to a table
  app.select([t.rows[1], t.rows[2], t.rows[3]])
  //Error > Expected array of objects but received (Row,Row,Row)
  

  App.Select(t.Rows[1]) works very well. But when I want to select multiple lines, that is not.

  Any advice?

  TIA Loïc

  Hey!

  Try selecting each line separately:

  var myT = app.selection[0].tables[0];
  myT.rows[0].select();
  myT.rows[1].select(SelectionOptions.ADD_TO);

• Select * from relational (&lt; schema &gt;. &lt; table &gt;)

• SQL SELECT to hierarchical tables: START WITH... CONNECT BY...

  This seems to be a simple problem, but I think that I have enough intelligence SQL to solve.
  
  I have a table called DE_DOMAIN. The columns of interest are:
  DOMAIN_ID - PK
  NAME
  PARENT_ID - FK (can be NULL), poining to CF of the parent
  
  What I want is: Returns a hierarchical list, containing: column 3 above as well as the NAME of the parent.
  
  Regardless of the name of the parent, it works fine:
  SELECT DOMAIN_ID, PARENT_ID, level
  OF DE_DOMAIN
  WHERE SUPERDOMAINE = 2673
  Start by PARENT_ID IS NULL
  Connect DOMAIN_ID PARENT_ID = prior
  BROTHERS AND SŒURS ORDER BY NAME ASC
  
  and I get:
  11 rec_11 1 Null
  15 rec_15 1 Null
  16 1 Null rec_16
  17 1 Null rec_17
  22 17 2 rec_22
  1 2 17 rec_1
  rec_25 25 17 2
  2 2 17 rec_2
  
  i.e. records with PK = 1, 22, 25, 2 have all like parent record with PK = 17, then the new column name, they must bear the name of the parent (i.e. rec_17).
  
  A simple idea?
  Thank you very much.

  Hello

  You can use the FIRST operator in the SELECT clause.
  I don't have a version of your table, so I'll use scott.emp to illustrate:

  SELECT     empno
  ,     ename
  ,     mgr
  ,     PRIOR ename    AS mgr_name
  FROM     scott.emp
  START WITH     mgr     IS NULL
  CONNECT BY     mgr     = PRIOR empno
  ORDER SIBLINGS BY     ename
  ;
  

  Output:

  .    EMPNO ENAME             MGR MGR_NAME
