• Switch the setting to a page of the window parent child and store session values in the parent window

  Hello

  I have two pages of the apex. I open a page of the child using javascript in the parent page.

  Parent window has the following articles.  P1_Text1, P1_text2, P1_text3. The setting is 'Change only when the session state is null', static assignment.

  In the child window: I have two buttons 'Confirm' and 'close '.

  When I press "confirm", it sets the value of a page element parent in a process of PL/SQL.

  BEGIN

  / * some calculations

  followed by an assignment statement * /.

  : P1_Text1: = final_value;

  END;

  "Close" button in the child window. as a result of javascript that are associated with:

  JavaScript:

  Window.opener.Location.href = window.opener.location.href;

  Window.Close ();

  
  

  When I press the close button, the parent window gets updated and P1_Text1 is responsible for the requirements.  Everything is going well so far.

  
  

  But the problem is with other elements of the parent page. They become null.

  
  

  How to store the values of the elements of the page of the parent window?

  
  

  
  

  Kind regards

  How to store the values of the elements of the page of the parent window?

  Problem: You're not 'save' the other page elements.

  Solution: Before you open the child window, you need to "introduce" the values desired registered on the server.

  This is best done with a dynamic Action that uses a PL/SQL code block.  The key is to include all the items you want to store the property in the "Page" referred to submit

  PL/SQL code is a code simple no - ops

  begin
    null;
  end;
  

  For you, it seems that the 'child window open"should be action 2 of this dynamic Action.

• HOWTO estimate of progress during the use of parallelism of the iteration?

  If I have a loop with the parallelism of iteration activated, is there a good method for updating a progress bar without eliminating the potential speed boost?  The naïve approach to divide the final iteration by the total number of iterations is going crazy when I paralellisme iteration.

• Simulate the 1 - N N - N relationship using the Parent-child structure

  Hello
  
  I have a 1-N relation between SKILL tables and the USER, which means 1 skill can be applied to multiple users. A jurisdiction may have a parent jurisdiction, which means that a ParentSkill inherits all the privileges of his child.
  
  I would like to simulate a N - N relation between the users and the skills by building a vision that goes through the parent-child relationship. This is possible for the construction?
  
  
  Current structure:

  |USERID | USERNAME | SKILLID  |
  +-------+----------+----------+
  |   1   |  Jack    |      1   |
  |   2   |  Simon   |      1   |

  +-------+----------+----------+
  
  
  |SKILLID | DESCRIPTION   | PARENTSKILL  |
  +--------+---------------+--------------+
  |   1    |  Mechanic     |      2       |
  |   2    |  Inspector    |      3       |
  |   3    |  Supervisor   |      null    |
  +--------+---------------+--------------+

  Favorite exit (the skillid order is not important):

  |USERID | USERNAME | SKILLID  |

• Prevent the child class dependency when the conditional use disable to specify the class in the development environment

  Hello

  I develop an application that I want to run on the normal systems and in real time using LabVIEW Proffesional Development System 2012 SP1

  To control how the application interacts with the user, I created a class that defines the type of user interface behavior that should allow me to have nice dialog boxes when the system is running on a machine windows and no dialog box (or any other friendly code in non-real time) if they sail on a real-time target.

  The parent class is the code that suits the actual time and the class of the child is the one with dialog boxes.

  To control the class of which it is responsible, I have a structure conditional disable. It works fine when the application is built in an executable or executable file in real time, but the problem arises when I want to use the code during development on the target in real time.

  I think that with the application under a target in real time (RT PXI), the proper case of the conditional - disable is enabled for the parent class is used, but the child classes are also listed under dependencies - I pressume it's because they exist on the block diagram in the case of persons disabled conditional turn off the diagram.

  This means that I can't deploy the code on the target in real time as it is unhappy with the class of the child code - even if it will never run.

  To save the poster my real project, I created an example with a Parent and child class and a flag to disable conditional 'class' to illustrate the problem.

  If you run Test.vi, you will see that the child class always gets locked (i.e. is addictive) while running even if it is not called.

  So - basically my question is: is what I can do about it or will I enough to disable it with conditionals and simply put the constant to correct class on the block diagram in the tests?

  Thanks in advance

  John.

  I feel your pain.  I came across something similar some time back.

  Apparently official NOR position is that you have to put a conditional structure of Disable IN EVERY ONE OF YOUR CLASS live.  In the Windows screws, you simply have a case of empty disable conditional with the windows code in another case and vice versa on the RT.

  I also much prefer the method you describe...

  Massari,

  Task.Java seems good. The question is: how to create the new instance of task assignment in the UI?

  That's what you do: you must use the create operation standard of the palette of the title of the collection of nested task assignment data control. Thus, enrich the collection of task, the collection taskAssignment nested in the task, expand the node of the operations and drag and drop the operation of creation on your page. This should add the new instance to the collection of the current task task assignment. To make sure that this is the case, set a breakpoint in the addTaskAssignment method in Task.java. Then, when you save the parent task, load useful json must include a table nested with the new task assignment.

• Default filters that users can delete (in the parent/child Setup)?

  Is it possible in Latitude 2.2.2 to have filters (filters of the range, refinement filters etc.) applied by default (which means that users see these filters when they log-in), but they can also remove (using bread crumbs portlet) if they wanted to? We tried to use the source of data (JSON) filters (using 'baseFunctions' setting) where we have a parent/child Setup, but it seems these filters cannot be removed once applied. Note that filters can be removed if we do not have a parent/child relationship between the data sources, but as soon as we introduce a parent/child relationship between the data sources (which we need), the GET of sticky filters and cannot be deleted. Any reason why the parent/child relationship causes the filters becoming sticky? Any way (alternate) to reach what we want?

  I think that it is a known problem (LSTUDIO-5088) and there could be a fix for this. You can contact technical support to obtain the fix.

• 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!

   manager_id          NUMBER, 
   employee_id      NUMBER,
   CONSTRAINT join_table_pk PRIMARY KEY (manager_id, employee_id),

  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
   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)
    GROUP BY name
    CONNECT BY prev = PRIOR curr AND name = PRIOR name
    START WITH curr = 1
  )
  SELECT a.*
  FROM   manager_list m,
         all_list a
  WHERE  m.employees = a.employees

  For example, there are 3 ContractIdentification tags. Example 1:

  All values of contractident are concatnated and returns posted 19 go.
  
  Can someone help me to extract the last number of each tag value of ContractIdentification and create the 3 files

  Hello

  The result I got was:

  16RTE_20100331_1500_20NG_20100331_1500_6

  In the query have you tried, access you a single record if you can not expect to get three rows of "magic". The EXTRACT function works as planned, it retrieves the nodes required, but the result is always a fragment of XML (a scalar value).
  To achieve your goal, you must divide the sequence MolTimeSeries in relational lines.

  Two similar solutions are possible, XMLTable (10gr 2 and more) or Table/XMLSequence.
  In your other post, you mentioned db version 10.1, so I guess we go with XMLSequence:

  SELECT 'RTE'
         ,to_date(substr(extractvalue(x.xml_data,'/MolDocument/ValidTimeInterval/@v'),1,16),'yyyy-mm-dd"T"hh24:mi')
         ,decode(extractvalue(x2.column_value,'/MolTimeSeries/Direction/@v'),'A01','Up','Down')
         ,to_number(regexp_substr(extractvalue(x2.column_value,'/MolTimeSeries/ContractIdentification/@v'),'\d+$'))
         ,to_number(extractvalue(x2.column_value,'/MolTimeSeries/Period/Interval/EnergyPrice/@v'))
         ,sysdate
         ,null
         ,null
         ,extractvalue(x2.column_value,'/MolTimeSeries/ContractIdentification/@v')
         ,'SUBMITTED'
         ,'A96'
         ,null
         ,sysdate
  FROM xml_demo x,
       table(
         xmlsequence(
           extract(x.xml_data, '/MolDocument/MolTimeSeries')
         )
       ) x2
  WHERE existsnode(x.xml_data,'/MolDocument/DocumentIdentification[@v="MOL_20100331_1500_1600"]') = 1;
  

  Also note the use of instead of the ordinary SUBSTR REGEXP_SUBSTR because he has not worked for "NG_20100331_1500_6".

  Hope that helps.

• Update the data to uppercase in the parent/child tables

  Hi gurus!
  
  In production, we have a table product and that is in reference by many tables making parent child relationship. By mistake, we realized last month some products have been added to lowercase and now we have a request to update all these product codes uppercase so that existing code that use these tables have no impact. Appreciate if you can give an idea about how can I update the existing data in the table parent uppercase as well as child records?
  
  Concerning
  Sri

  Are the product code that you need to update what is stored in the tables of children? If Yes, then you must do it in several steps, something like:

  Identify the child tables

  SELECT table_name, constraint_name
  FROM user_constraints
  WHERE r_constraint_name = (SELECT constraint_name
                             FROM user_constraints
                             WHERE table_name = 'PRODUCT_TABLE' and
                                   constraint_type = 'P');
  

  Create new product of upper-case code in the product table:

  INSERT INTO product_table
  SELECT UPPER(product_code), other_columns
  FROM product_table
  WHERE product_code <> UPPER(product_code);
  

  Update the children tables for caps product codes

  UPDATE child1
  SET product_code = UPPER(product_code)
  WHERE product_code <> UPPER(product_code);
  

  Finally, remove the tiny product_table product codes

  DELETE FROM product_table
  WHERE product_code <> UPPER(product_code);

• ATER the MovieClip Parent child size resize?

  My main movie clip has a child clip inside. When I resize the main clip the child clip dimensions seem to stay the same. I perform a trace on the width and height of the element of the child, and no matter what I resize the main clip to the dimensions are the same as before. It is possbile to know the size of what the child is after a parent resize? Thank you

  You're scaling of the parent and if the child clip will appear larger.
  its width and height will remain the same. This is because it is of dimensions
  have not really changed, her parents have. To get the clip of the child
  * screen * use of width:

  nActualWidth = mcParent.mcChild._width/100*mcParent._xscale;

• Parent-child queries to the Web Service 2.0

  Hello
  
  Our team has begun working on the integration of ws ws 1.0 2.0. A question of Tuff which meet us and we are looking for assistance is:
  
  As inside 2.0 all objects are exposed to the same level and the attachments of the child objects are not exposed (compared to the 1.0 ws that attach childs along ListOfXXX, parents), we wonder how to interrogate these child objects now? More explicitly, namely the parent object, how to retrieve its child objects? Or it is impossible since ws 2.0?
  
  This question is really confusing us now, and we have not found the answer in the new "Oracle Web Service on request Guild v4.0.
  
  Any help/answer/comment/suggestion on this issue would be grateful!
  
  Fang

  At that time, WS v2.0 does not support child objects. It supports only the top-level parent objects. So if you need for the child o bjects query, you will need to use the interface of WS v1.0.

• Cannot open the component of the battery of the 3rd generation Apple TV remote.  The "cover" stripped is by using a coin to turn the cover counterclockwise. Any suggestions?

  On the component of the battery of the 3^rd generation Apple TV remote, the "lid" is getting stripped by using a coin to turn the cover counterclockwise. I even used a screwdriver flat head with a cloth & it will not always be open.

  It is partially open, but I think there was some debris. I disabled the debris, but the "lid" is badly stripped. I stopped as I would not completely destroy the compartment cover. Any suggestions?

  I had a similar problem with another camera, but a very similar configuration, a round lid on a stack of pancakes about two years ago. I got to have adhesive PuTTY handy of Museum at the time.  I took enough Putty to cover the circular cover, let it sit for just a moment, or so that he could 'stick' (it's not like glue, it will come off easily). I have enough of the dough (about a 3/4 inch ball) used to create a handle and everything pushing down pretty firmly on the sealant to keep it on the cover, I did one-quarter turn and cover came out. I just took my money AppleTV 3 remote out of storage and tried this technique on her, and she seemed to cling to the coverage and helped me with the tour. My remote money is not received tap stuck like yours and the housing is in good condition. But it might be interesting to try. If you live in Irvine, California you should probably have some of this PuTTY on hand. It is usually used to prevent the fall during an earthquake of trinkets and other fragile objects of light weight. If all else fails, a new remote money is always available on the Apple Store for $19. Good luck.

• The unnecessary use of synchronize in code example in the Dev Guide

  I ask this question with some trepidation, I'm sure someone out there will be able to explain it and then I'll feel really stupid asking.  But that's...

  Using a HTTP connection code sample in the developer's Guide (I checked 4.3 and 4.5, and it's the same in these two levels), use synchronized in two places that I don't understand.

  (1) getUrl() - Code follows

  /**
  * Retrieve the URL. The synchronized keyword ensures that one
  * thread at a time can call this method on a ConnectionThread object.
  */
  public synchronized String getUrl() {}
  Return _theUrl;
  }

  I understand the comment, and it is sometimes useful force methods you want to synchronize.  But not this method in vessel closed.  If anything, there are more cases of use of this mechanism for the recovery method in this code.

  (2) around of the fetch block - following Code:

  / * Make sure that pull requests are not missed
  * While the received data is processed.
  */
  {Synchronized (this)}
  Open the connection

  When I see a synchronization block like that, I guess it's a little shared code that can be executed by multiple threads, which this clearly isn't.  So why is it synchronized?

  In fact, I think that 'design' is a testament to this example may be imperfect.  I think it would be better to have a new Thread for each connection, or have a queue (synchronized) URL addressing.

  As evidenced by another thread on this forum, the developers make these samples as Gospel and try to use them.  So if this is wrong, perhaps we could fix.  But maybe it just me being a lumberjack full.  Wouldn't be the first time...  And won't be the last!

  It seems that this example has been designed with a base defense to the following (if no synchronization) scenario:

  Event thread request _start = true.

  Threaded starts the connection.

  Event thread again pray _start = true.

  Threaded end connection, defines _start = false.

  Net result: the second event thread request is not met.

  That being said, the guys are right: this design is mediocre at best.  In the scenario above, the second request of event thread is blocked while the thread of the connection ends... and as everyone knows at this point, blocking the event thread usually leads to a world of pain.  There are certainly better approaches that can be used here, and probably the easiest way to this problem is just to have the best control flow, such as not allowing not a new connection request while one is already underway.  Certainly the synchronization adds excessive complexity to this problem and distracts from what the sample is trying to demonstrate: a simple HTTP connection.

  For this example, and the extraction, I will recommend to the authors that both be reviewed and be a structure such that these samples are as simple as possible.  Thanks to Peter marchywka for their suggestions.  Comments like yours, it's how we identify areas for improvement.
