  Specifically, the two simple solutions provided were:

  1 using the row_number, entitled Oracle ranking based on descending order of the inside telephone each empnum group. And finally selects the lines which has least rank (of least since that order is descending for phone).

  SQL > column alternatecontact format A20;

  SQL >

  SQL > SELECT empnum, alternatecontact, relationship, phtype, phone

  2 from (SELECT a.*, row_number() over r (PARTITION BY empnum ORDER BY phone / / DESC))

  3 FROM xxc_contact one)

  4. WHEN r = 1

  /

  EMPNUM ALTERNATECONTACT RELATIONSHIP PHTYPE PHONE

  Home 123458 Maggie Greene CH 6666666666

  2. with the help of MAX, Oracle automatically assigns the maximum phone for all the rows in each group of empnum. And finally selects the rows with the maximum phone. Order by clause is omitted here intentionally. You can find out why.

  SQL > SELECT empnum, alternatecontact, relationship, phtype, phone

  2 (SELECT a.*, MAX (phone) over (PARTITION BY empnum) rn FROM xxc_contact one)

  3 WHERE phone = rn

  4.

• ADF tree-table using the single object view

  Hi all

  I'm pretty new (in fact, quite new) to the development of the ADF so bear with me here.

  I use JDev version 11.1.1.7.0

  My question is this: -.

  I have a single table, with a single entity object and view read-only of the object, metaphorically, sitting on it. This table contains attributes such as Type of system, Application name, content of the Message, etc. It is used as a repository of audit trail for many applications in our field.

  Now what I want to do is create a style tree-table menu to allow the user to select a system Type (is there a lot of them) and cross the names of applications that are related to the type of system selected. Getting the granularity I'm not further than the name of the Application. When a user clicks on the Type system or a given Application name, the ADF array element that I have on my page .jspx should perform a partial page refresh to filter results accordingly.

  That's what I'm thinking the tree-table to look like:-l' user must be able to expand and collapse the nodes as needed.

  Type of <>

  < A system >

  < A.1 application name >

  < A.2 application name >

  < A.3 application name >

  < B > system

  < application B.1 name >

  < name B.2 of the application >

  < system C >

  < name C.1 of the application >

  etc...

  I did some research and I'm not sure I'm able to do what I ask with a single view object. Many articles and tutorials I've read up to now focus on the view of the objects that contain the link relationships with one or more display objects. This obviously creates a relationship master / detail that is easily available for the course I guess...?

  Any help would be greatly appreciated.

  Thank you

  JimBob

  No, you probably can't perform this operation with VO alone (because you do not have a recursive structure if I understood your sample).

  You'll need VO to 'Types of system' (as the root of the tree), VO for the 'systems' (logged on 'Types of system' VO with ViewLink) and VO for 'Requests' (connected on 'Systems' VO of ViewLink).

• Create a tree of a single object View table

  Hi all
  
  I use Jdeveloper 11 g PS2
  
  Can someone tell me how to create a table of tree of a single VO?
  
  Looks like Frank Nimphius has posted an article on this entitled 'how-to create a picture of the tree to a single object View and how to get access backstage for the data lines' but all links to it repoint towards http://www.oracle.com/technetwork/developer-tools/jdev/overview/index.html. I couldn't find it on Connotea, nor was it explained in the book the Oracle Fusion developer's Guide.
  
  I have no problem, creating a tree with two table, but it is redundant in my case, because the tree is based on a car that references the table. My association of entity is already created that binds the parent_id column column id. And I have a link to view based on the association of the entity. I also create a view for my VO that filters the parent (parent_id = null) records and criteria applied to the instance of VO in the data model. I also have a detail THAT VO from my view link.
  
  I drag the object instance view my page of the data control panel and select create table tree. In the Edit Connection dialog tree, I press the icon ' green more "to create the level rule tree to the child nodes, and then select the accessor to display the child records and he applies it my rule of high level (normally with two your I get a rule of the child based on the accessor). When I run the page it seems to work a certain number of records but I get duplicate at the end lines and page crashes.
  
  I'm sure it's something simple, I am on here. Any help will be appreciated.
  
  Thank you

• Dynamic processing of single quotes in SQL

  Version: 11.2.0.4

  I'm kinda a beginner when it comes to dynamic SQL.

  I had a condition in which I had to run the following command on all the data files in the DB.

  -Expected results

  change datafile resizing '< Filename >' database 10g;

  The name of file, which is generated dynamically must be in single quotes.

  -Sample data

  create table x (file_name varchar2 (90));

  Insert into x values ('/ u04/oradata/ORCL/system.dbf');

  Insert into x values ('/ u04/oradata/ORCL/sysaux.dbf');

  Insert into x values ('/ u04/oradata/ORCL/users01.dbf');

  I managed to do it using a similair below code. But I had to do several things of trial and error to get this working in reason to get the correct number of single quotes for the string generated for v_sql below. So, I want to rethink the basics.

  declare

  v_sql varchar2 (350);

  Start

  for rec in (select x file_name)

  loop

  v_sql: = "alter database datafile"'| " Rec.file_name | " 'resize 10g;

  -RUN IMMEDIATELY v_sql;

  dbms_output.put_line (v_sql);

  end loop;

  end;

  /

  ALTER database datafile ' / u04/oradata/ORCL/system.dbf' size 10g

  ALTER database datafile ' / u04/oradata/ORCL/sysaux.dbf' size 10g

  ALTER database datafile ' / u04/oradata/ORCL/users01.dbf' size 10g

  PL/SQL procedure successfully completed.

  I would like to know the role played by each single quote. I used 8 apostrophes in the V_SQL variable above, and I numbered each single quotation mark as shown below.

  1                        234                 567           8

  |                        |||                 |||           |

  v_sql: = "alter database datafile"'| " Rec.file_name | " 'resize 10g;

  Example of output from the generation of dynamic channels:

  alter database datafile '/u04/oradata/ORCL/users01.dbf' 10g resizing

  1 and 4-> start and end of the string alter database datafile '

  3 > literal single quote of string in red in the example output

  2 > escape 3 (single literal quote of string)

  5 and 8-> start and end of the string ' resize 10 g

  6-> escape 7 (single literal quote of string)

  7 > literal single quote of string in green in the example output

  My asssumptions are correct?

  I would like to write like this.

  declare
     v_sql    varchar2(350);
  begin
    for rec in (select file_name from x)
        loop
          v_sql := q'[alter database datafile '#FILENAME#' resize 10g]';
          v_sql := replace(v_sql, '#FILENAME#', rec.file_name);
          --- EXECUTE IMMEDIATE v_sql;
          dbms_output.put_line ( v_sql);
      end loop;

• Poor performance during the iteration/update rows of a tree table

  Hello
  
  We have a tree table based on a VO and EO (with transitional attributes). One of the attributes is an indicator.
  The original Version is filled with a complex query with several thousand lines.
  
  Now, when the user clicks on a node, all children are updated (their flag is set to true) recursively.
  
  It's really really slow. It may take several minutes, while a similar update via PL/SQL on a real table would take a few seconds.
  
  Is it possible to improve the performance? We have already applied all the tunings on EO as VO mentioned in the Oracle Documentation, but they had almost no effect:
  -keep the viewlink iterators set line
  -indicators of query
  -Use the batch update
  
  The algorithm we use is the following:
  

      private void checkTreeNodes(JUCtrlHierNodeBinding node, Boolean check) {
          if (node == null) {
              return;
          }
  
         TreeVORowImpl nodeRow = (TreeVORowImpl)node.getRow();
          if (nodeRow != null) {
                  nodeRow.setFlag(check);
          }
  
          List<JUCtrlHierNodeBinding> children = null;
          if (!nodeRow.getLevel().equals("4"))  // no more than 4 levels
              children = node.getChildren();
  
          if (children != null) {
              for (JUCtrlHierNodeBinding _node : children) {
                  checkTreeNodes(_node, check);
              }
          }
      }

  Hello

  try to move the logic of the definition of the transitional indicator at the service of the company (method exposed on the client interface) and then refresh the tree instead of a record thousand on the client component analysis.

• How can I find levels of knot / depth of recursive tree table?

  Guys,
  
  With the help of Studio Edition Version 11.1.1.3.0.
  
  After 2-3 days of banging my head against the screen, I'm ready to ask for help. I confess: I'm a noob and can't find a way to get the node level / depth of a treeTable. I've not seen mentioned in the forums or in one of the examples of treeTable on different blogs. Google, the praise of God, I was missed as well.
  
  I tried in my Parent-> children-> tree table Recursive Child (the child of references view object):
  
  (1) EL expressions (my EL sucks) in a text output in the node. Hoping that something like #{node. HierTypeBinding.Parent.etc.}, would produce a kind of valuable info I could handle.
  (2) setting the value of a managed bean node, but do not know how to get the currently rendered node. I can only figure out how to get the node currently selected, which is only useful after the table has already been made.
  (3) level creating a transitional field called in the child view object and setting its equal to level sound + 1 ViewRowImpl, but if the child has many parents, I get incorrect calculations. I have the most away with this, but finally gave up. To access the feature through ViewLinks works great to browse children lines, but by train to get parent node is disconcerting if you have several parents.
  (4) the two saying "Please!" and various metaphors of four colorful letters. Not had much effect.
  
  Any kind of branch or help would be great.
  
  Thanks guys,.

  Based on the Employees table in the HR schema, a link is defined between the employee-id and the id manager.
  When an instance of the view that above is used as table (recursive) tree, I am able to find the depth of the node.

  Example code:
  JSPX code fragment:

  
  selectionListener = "#{bindings." Employees.treeModel.makeCurrent}.
  rowSelection = "single" id = "tt1".
  styleClass = "AFStretchWidth" >
  
  
  
  *
  ID = "ot3" / >
  
  
  
  
  
  

  PageDef:
  
  
  
  
  
  
  
  
  
  
  
  

  Can you have the same card in your scenario and see if you can get the depth of a node?

• Creating tables in a nested for loop

  Hi all.

  I was stuck in this problem for quite a while now and I still don't know how to continue. Some outside the entrance would be greatly appreciated!

  I'm doing the following:

  -Take an array of numbers, to check if they are within a certain range (e.g. between 2 and 4)

  -Build two new arrays: one with all the numbers that are inside the beach and the other with the rest.

  An additional condition is that the amount and value of the range conditions will change (for example, it could be between 2 and 4 only / 2, 4 AND 6 and 7 according to the entry)

  To treat this, I created two nested for loops - one that goes on a table that contains conditions of the beach and inside that actually go and check if the values are in the range. I think I did that part successfully, but the next part is confusing to me - how to actually create the tables separated within two loops for?

  My apologies if I did not explain it well. Another method to support this problem is I want to translate following LabVIEW:

  Ranges of table / / [1 5 7 10] exodus-> This means we want to divide numbers based on those who are in (1,2) and (4.5) against those who are not

  Table of values / / [2 3 6 11 3]

  EndOperationDelegate table / / array of values within the range
  Table outValues / / Array of values out of range

  for m = 1:size (ranges)

  for n = 1:size (values)
  If (THE NUMBER IS on the INSIDE of EACH RANGE)
  EndOperationDelegate = [EndOperationDelegate NEWNUMBER]
  on the other
  outValues = [outValues NEWNUMBER]
  end

  end
  end

  Sounds easy enough, but it gets so chaotic with Labview that I don't know what to do. I have attached a reference image - insertion in the array function is not in fact add to the table, it creates a new table. How can I save that for when the nested for the ends of the loop?

  I have seen a few examples with shift registers which lie in a loop and I couldn't successfully that transfers in my block diagram.

  Any help/direction would be greatly appreciated.

  Hello!

  See the following example to understand how you can create a table in the loop For

  

  In your case, you also can uce conditional terminal to create a table only when then located nearby. It makes the code much cleaner that the structures of the case

  Hope this helps, if not, let me know if I can help you!

• Retrieve child line selected a tree table

  Hi all

  I have a tree table which includes two levels and one of the data in the column of the child node has a command link. Clicking on it calls a support bean method that tries to get the line that contains the command link that was clicked. The problem is, trying to get the line clicked (selected), it always returns the row parent of the node. I searched and followed by some examples of code, but it does not work for me.

  For example, if the table tree looks like, where X expands to show the children X 1 and X 2 lines:

  X

  L X 1

  L X 2

  Then clicking on the link to X 1 or X 2 will call code that returns the line for X.

  Here is the code in my grain of support:

     public void viewInspectionRecord(ActionEvent actionEvent) {
  
        RowKeySet rks = treeTable.getSelectedRowKeys(); 
        
        Iterator rksIterator = rks.iterator(); 
        
        if (rksIterator.hasNext()){ 
           List key = (List) rksIterator.next(); 
      
           JUCtrlHierBinding treeTableBinding = (JUCtrlHierBinding) ((CollectionModel) treeTable.getValue()).getWrappedData();     
           JUCtrlHierNodeBinding nodeBinding =  treeTableBinding.findNodeByKeyPath(key);     
           
           Row rowData = nodeBinding.getRow();
          
           if (rowData == null) {
               FacesMessage facesMessage = new FacesMessage("Please select an Inspection Record record to view details");
               FacesContext.getCurrentInstance().addMessage(null, facesMessage);
               
               return;
           }   
           
           Object irId = rowData.getAttribute("QarsInspectionRecordId");
           
           ...
    }
  

  rowData.getAttribute("QarsInspectionRecordId") eventually throw a NullPointerException because it is an attribute defined with the parent node and any children.

  Any ideas what's happening?

  Thank you

  I am following up to the memory of the server and I still have available memory...

  Apart from the problem of memory I know that this type of load should be possible because the step of data load on LKM SQL to Oracle is able to load the work table $ CAN. Ideally, I want to emulate this behavior by using SQL for SQL IKM.

  1 - What is the right path to follow here? (change the parameters of memory or modify the IKM?)

  
  

  2 - ideas on how to solve the OutOfMemoryError: GC overhead limit exceeded error? (GC means Garbage Collector)
