• Can I use a reference WITH clause in a JOIN?

  Is the syntactically correct query?

  WITH abc AS

  (

  SELECT a.col1 d,

  e a.col2

  substr(a.Col1,2) f

  FROM table1 a JOIN

  Table 1 b ON a.col1 = b.col1

  WHERE a.col2! = b.col2

  )

  SELECT id, name, date of birth, ssn

  FROM table3 LEFT OUTER JOIN (SELECT DISTINCT abc.d of ABC WHERE abc.f = 'EF') / * Please note the addition of the WHERE clause in the veiw inline * /.

  ON table3.id = abc.d

  I try to use "abc" with a JOIN. Are there restrictions WITH clause?

  Thank you!

  I apologize I addded the WHERE clause too in mode inline "abcd" (in your query) to understand the purpose. The purpose of doing an OUTER JOIN of "abc" with table3 is to check the "EF" State = abc.f. Please note the Add where clause to update in my original question now.

  I see the changes, but everything in #5 response still applies.  There is no need to make a join in this case.  The output depends entirely on table3.  You will get the same results no matter what, if anything it either, is in table1, so any reference to table1 does that complicate the query and makes probably slower.

• How to use WITH Clause of Apex classic report

  Hello.

  I use Apex 4.2.1 on mod_plsq and Oracle 11 g 3.

  I need to create a report classic usiing a WITH clause in the SQL report.  Apex keeps throwing the error 'CAN finf SELECT statement.

  I then wrapped my report query in an envelope, SELECT * clause.  Apex then raises an error you need to use a variable LONG.

  How is - a uses a WITH clause in the report query.

  Huh?  How can you put a SELECT statement in a procedure?  you return a cursor reference?

  You create VIEWS.  You have three sections.  Give an opinion on each of them.  Test them with SQL Developer (or SQL * more)

  Build from there.

  In fact, it looks like you are trying to compare two tables"and return a DIFF

  THINKING IN SETS

  Use the WITH clause to build a 'virtual' table for EARLIER_NOTICE and a 'virtual' table for LATER_NOTICE.

  Use FULL OUTER JOIN to compare the two.

  THE FORMAT OF THE EXAMPLE:

  select * from (
  with w as ( .... )
  ,table_A as ( -- build the Virtual Table for EARLIER_NOTICE
  SELECT *
   FROM
   V_URMT_COMPARE_NUCLIDE_DATA A1
     join W on (A1.urmt_btrs_pk, W.urmt_btrs_pk  and A1.earlier_notcie_id=W.earlier_notice_id)
  
  --  old code
  -- WHERE
  -- 1 = 1-- why???
  -- AND A.URMT_BTRS_PK     = (SELECT URMT_BTRS_PK FROM W)    --TO_NUMBER(:P202_URMT_BTRS_PK)
  -- AND A.URMT_NOTICES_ID = (SELECT EARLIER_NOTICE_ID FROM W)   --TO_NUMBER(:P202_COMPARE_EARLER_NOTICE_ID)
  ,table_b as ( -- build the Virtual Table for the LATER_NOTICE
  
   select *
   from
  
   V_URMT_COMPARE_NUCLIDE_DATA B1
     join W on (b1.urmt_btrs_pk = W.urmt_btrs_pk  and b1.urmt_notice_id=W.later_notice_id)
  )
  
  --/*** NOW - WE COMPARE THE TWO ***/
  select CASE
      when A.urmt_btrs_pk is null then 'ADDED'

• Want to get an overview with the photo viewer and open with Photoshop

  Hello.  In all previous versions of Windows, I was able to do.  Right-click on an image and the 'Preview' option would open the image in the Windows Photo Viewer, and the option 'Open' it would open in Photoshop (or whatever the editor, I had chosen).  I just installed Windows 7 and I seem to be unable to get to do this.  If I select "Photo Viewer" as the default program for jpg files, I have TWO options 'Preview' in the right click menu.  Both will open it in Photo Viewer.  If I select Photoshop as the default program for jpg files, I get a 'Preview' and 'Open' option, but both open the image in Photoshop.

  How can I configure "Preview" with Photo Viewer, and 'open' with Photoshop?

  Thanks for the tips of registry.  I managed to find and fix the problem.  I tried to fix paint.net as the program open by default, and it has open in paint.net and presented in preview in Photo Viewer.  So I thought it was something to go astray with Photoshop.  Under HKEY_Classes_Root\Photoshop.JPEGFile.9\shell, there is a key-file for 'Preview '.  I deleted who, and now it opens in photoshop and previews in Photo Viewer.

  Thank you

  Yes, if the emp is an alias and emp is also a real table, and both have a scope, then Oracle assumes you mean the alias.  To avoid confusion and errors, do not use the actual table as alias names.

  It goes same for columns and column aliases.

  In PL/SQL, the same type of confusion can arise between the variables and the column names.  When there is a choice, Oracle assumes you are talking about the variable.

  The error has actually nothing to do with the WITH clause.

  Join conditions (i.e. the conditions following the keyword WE) must be expressions that are evaluated to TRUE or FALSE.  The join condition, you have validated, however

  (R.ITERATION + 1) + B.NUM

  corresponding to a NUMBER.  The following would be a valid join condition:

  (R.ITERATION + 1) = B.NUM

  but I don't know if it of what you wanted or not.

• What version of VMware View is compatible with vSphere 5.1?

  Greetings,

  I checked the compatibility tables and I watched that indicated that no version of VMware View was compatible with vSphere 5.1.

  Tom

  You will have to wait until VMware releases a hotfix or an update that is compatible with vSphere 5.1. Usually short gap between the release of vSphere and a compatible version of the view.

  The following query illustrates the structure:

  [code]

  WITH tree(dpt_id, dpt_name, parent_dpt_id, lvl) AS
  (
    SELECT d.dpt_id, d.dpt_name, d.parent_dpt_id, 1
      FROM departments d
     WHERE parent_dpt_id IS NULL
     UNION ALL
    SELECT d.dpt_id, LPAD(' ',t.lvl + 1) || d.dpt_name AS dpt_name, d.parent_dpt_id, t.lvl + 1
      FROM departments d
     INNER JOIN tree t
             ON d.parent_dpt_id = t.dpt_id
  ) SEARCH DEPTH FIRST BY dpt_id SET A
  SELECT * FROM tree;
  

  [/ code]

  However, I need an additional indicator on all records. I need to know if a given "Ministry" has "descendant nodes.  But I don't know how I can do it. Is this possible with recursive clause with or I have to use a CONNECT BY?

  For example, in this scenario, the node 102 (AFRICA) has two childeren, but two invalids. So, it should return 0 for this node. Any idea?

  Thank you

  Ask yourself if you can include information about the child lines that you evaluate the WITH recursive clause?  Of course, but where you get this information?  You can join another copy of departments and call it c.  But since there is a one-to-many relationship between parents and children, you probably want to join an aggregate of departments, who has only 1 line by id.
  However, according to what results you want (you still have not shown or explained) there may be simpler and more effective to use a subquery (a scalar subquery, an EXISTS subquery or an IN subquery), either during or after the construction of the tree.

  Assuming you want to get these comes from the sample data you posted:

  Here's a way to do it:

  WITH got_valid_children AS

  (

  SELECT parent_dpt_id

  COUNT (*) AS valid_children

  Ministries

  WHERE is_valid! = 0

  GROUP BY parent_dpt_id

  )

  , tree (dpt_id, dpt_name, parent_dpt_id, lvl, valid_children) AS

  (

  SELECT d1.dpt_id

  d1.dpt_name

  d1.parent_dpt_id

  ,   1

  , NVL (c1.valid_children, 0)

  DEPARTMENT d1

  LEFT OUTER JOIN got_valid_children c1

  ON d1.dpt_id = c1.parent_dpt_id

  WHERE d1.parent_dpt_id IS NULL

  UNION ALL

  SELECT d.dpt_id

  , LPAD (' ', t.lvl + 1) | d.dpt_name AS dpt_name

  d.parent_dpt_id

  t.lvl + 1

  , NVL (c.valid_children, 0) AS valid_children

  DEPARTMENTS d

  INNER JOIN tree t

  ON d.parent_dpt_id = t.dpt_id

  LEFT OUTER JOIN got_valid_children c

  ON d.dpt_id = c.parent_dpt_id

  ) SEARCH FIRST BY dpt_id SET A DEPTH

  SELECT *.

  Tree

  ;

  However, in this case the ITI will be simpler and more effective to get the valid_children column after you have trained tree, like this:

  WITH the tree (dpt_id, dpt_name, parent_dpt_id, lvl, is_valid) AS

  (

  SELECT dpt_id

  dpt_name

  parent_dpt_id

  ,      1

  is_valid

  Ministries

  WHERE parent_dpt_id IS NULL

  UNION ALL

  SELECT d.dpt_id

  , LPAD (' ', t.lvl + 1) | d.dpt_name AS dpt_name

  d.parent_dpt_id

  t.lvl + 1

  d.is_valid

  DEPARTMENTS d

  INNER JOIN tree t

  ON d.parent_dpt_id = t.dpt_id

  ) SEARCH FIRST BY dpt_id SET A DEPTH

  SELECT m.*

  ,         (

  SELECT COUNT (*)

  Tree

  WHERE is_valid = 1

  AND parent_dpt_id = m.dpt_id

  ) AS valid_children

  M tree - m is for the home

• disadvantages of subquery factoring (with clause)

  Hi all
  
  What are disadvantages of subquery factoring (with clause) (if any)?

  Features have no disadvantages, disadvantages depends on how use you them...

• We can create a view or table with a form button?

  We can create a view or table with a form button using forms 6i?
  If Yes, what will be the command?

  Gul says:

  If Yes, what will be the command?

  Yes. You can. Use the FORMS_DDL built-in. For example

  BEGIN
    Forms_DDL('create table temp(n NUMBER)');
    IF NOT FORM_SUCCESS THEN
      Message ('Table Creation Failed');
    ELSE
      Message ('Table Created');
    END IF;
  END; 
  

  Hope this helps

• Blog post notes - automation View 4.5 with Powershell

  As I did, I posted on my blog site, a summary of the notes of the recent view video Bootcamp. I don't know why this one discusses View 4.5 instead of 4.6, but there was still some good information overview. I liked the fact that the speaker has shown a lot of living examples.

  This is false.
  
  Since recursive with clause Oracle11gR2 is supported.
  Correct this misrepresentation of the document.

• Create VO with CLAUSE

  I have need make a VO with CLAUSE as:
  

  SELECT Evento.CEDULA, 
         Evento.IDEVENTO, 
         Evento.IDPROYECTO, 
         Evento.DETALLE, 
         Evento.TOTALHORASNORMAL, 
         Evento.TOTALHORASEXTRA, 
         Evento.TOTALHORASESPECIAL
  FROM EVENTO Evento
  WHERE Evento.CEDULA IN (:p_persona_cedula)
  ORDER BY Evento.FECHAEVENTO,Evento.HORAINICIAL,Evento.HORAFINAL,Evento.CEDULA

  See the line: WHERE Evento.CEDULA IN (: p_persona_cedula)
  
  
  What type of use bind variable? P_persona_cedula is a String, I put only one value and I can't put multiple values in 'IN' clause
  
  Can I use any array, list or Collection as a Bind Variable Type? How can I do this?

  You cannot use a variable binding in an IN clause in a VO.
  Here are some workarounds: http://jobinesh.blogspot.com/2010/09/using-bind-variable-for-sql-statements.html
