• FETCH ONE RECORD IN THE SECOND TABLE OF CORRELATED SUB QUERY

  Hi all

  I have provided the script below, I want to single fecth record in the second table in the join query,

  based on the example below, I want to go get one record of the table emp2 what matches with the emp_id of table emp1, please note emp2 may contain more record for the emp_id emp1 which respects

  all records can be selected in the table emp2.

  DROP TABLE emp1.

  CREATE TABLE emp1 (emp_id NUMBER);

  INSERT INTO emp1 VALUES (1);

  INSERT INTO emp1 VALUES (2);

  COMMIT;

  DROP TABLE emp2.

  CREATE TABLE emp2 (emp_id NUMBER, emp_name VARCHAR2 (100));

  INSERT INTO emp2 VALUES (1, 'Name1');

  INSERT INTO emp2 VALUES (2, 'Name2');

  My business logic will change to 'Fetch N second timeline table', that's the reason why I asked for a different approach, if I use max, min to achieve this does not allow me to evolve dynamically.

  Although logic has not been expressed at all in your original question, so good job I asked.

• no record in the main.active table?

  I just updated my Muse, made some changes to my site and saved. When recording, Muse crashed. Now when I try to open the site I get the message "cannot open this file in the Adobe Muse site. no record in the main.active table? I panic here a little... Please help. Thank you!

  The avalanche of reports of this error in November or in 2013 was due to a bug introduced in 7.0 Muse that has been fixed a week later under article 7.1. (The current Muse, 2015.0.1 equals Muse 12.1.)

  I am puzzled as to how this could happen while doing a backup, unless the file has been changed or renamed by someone else then only on the server? Or you were doing a save as (rather than a backup) over the original on the server?

  Could you send your file from MuseLog.txt to [email protected] as well as a link to this topic to the context? Can provide more information about what happened. Thank you.

• Help with the query to select only one record from the result set in double

  Hello

  Please help with the query. Version of Oracle database we use is 10g R2.

  I have a vision that is duplicated IDS, but they are used across the different functions. See below examples of data. Please help me with a query to select only one record (based on ID regardless of the area) from the bottom of the result set of duplicate records. For what is the point of view is there unique records, given the combination of the fields ID, Org, DF, dry, Sub-Sec

  ID	Org	DF	Sec	Sub-Sec

  Hello

  This sounds like a job for ROW_NUMBER:

  ORDER BY org

  ) AS r_num

  OF view_x

  He is a Top - N query example, where you choose the elements of N (N = 1 in this case) from the top of an ordered list.

  I hope that answers your question.
  If not, post a small example of data (CREATE TABLE and INSERT, only relevant columns instructions) to your sample data and the results desired from these data.  (I know that you said that you were a view selection.  Just for this thread, pretending it is a picture and post simple CREATE TABLE and INSERT statements to simulate your point of view).
  Point where the above query is to produce erroneous results, and explain, using specific examples, how you get the right results from data provided in these places.  (I didn't quite understand the explanation above.  I don't know why you want to

• Nested table of object type have only one record all the time

  Hi all
  
  I have a question regarding the storage of multiple records in a nested Table that is of type OBJECT.
  
  The program below that I wrote for the test and during the test, I was able to store only the last record in the nested Table.
  
  Please let me know what I did wrong here.
  
  Step 1:
  CREATE or REPLACE TYPE book_obj AS OBJECT (name varchar2 (25), author varchar2 (25), abstract varchar2 (4000));
  /
  
  Step 2:
  CREATE or REPLACE TYPE book_table IS TABLE OF THE book_obj;
  /
  
  Step 3: CREATE TABLE book (name, varchar2 (25), varchar2 (25) author, varchar2 (4000)) abstract;
  INSERT VALUES Accountants ('Harry Potter,' 'MK', 'It's magic');
  INSERT the book VALUES ("Ramayana', 'VK', 'It is mythiology'");
  COMMIT;
  
  Step 4:
  declare
  bookset book_table;
  ln_cnt pls_integer;
  Start
  bookset: = book_table (book_obj ('madhu', 'kongara', 'sudhan'));
  dbms_output.put_line (' the number is ' | bookset.) (Count); -> I see COUNT = 1
  bookset: = bookset_t(); -> Assignment to NULL.
  dbms_output.put_line (' the number is ' | bookset.) (Count); -> I see County 0
  for rec in (select * from book) loop-> now a loop twice.
  dbms_output.put_line (' name > ' |) Rec.Name);
  bookset: = bookset_t (book_t (rec.name, rec.author, rec.abstract));
  end loop;
  dbms_output.put_line (' the number is ' | bookset.) (Count); -> I can see COUNT = 1 (why?)
  END;
  
  I looped twice to fill two records in the TABLE IMBRIQUEE OF TYPE OBJECT. But when I see the Count I get only 1 and the data is also having the last record.
  
  Can you get it someone please let me know how to fill out the table nested with all records. Tell me where I am wrong.
  
  Very much appreciate your help here.
  
  Thank you and best regards,
  NKM

  Maldini says:
  dbms_output.put_line (' the number is ' | bookset.) (Count); -->, I can see COUNT = 1 (why?)

  Because instead of add to bookset collectionto set (ergo replacement) it a collection containing recovered book. Use:

  declare
      bookset book_table;
      ln_cnt pls_integer;
  begin
      bookset := book_table(book_obj('madhu','kongara','sudhan'));
      dbms_output.put_line('The count is '||bookset.count); --> I can see COUNT =1
      bookset := book_table(); --> Assigning back to NULL.
      dbms_output.put_line('The count is '||bookset.count); --> I can see count as 0
      for rec in (select * from book) loop --> Now Looping two times.
        dbms_output.put_line(' name > '||rec.name);
        bookset.extend;
        bookset(bookset.count) := book_obj(rec.name, rec.author, rec.abstract);
      end loop;
      dbms_output.put_line('The count is '||bookset.count); --> I can see COUNT =1 (why)
  end;
  /
  The count is 1
  The count is 0
  name > Harry Potter
  name > Ramayana
  The count is 2

  Or better use bulk collect:

  declare
      bookset book_table;
      ln_cnt pls_integer;
  begin
      bookset := book_table(book_obj('madhu','kongara','sudhan'));
      dbms_output.put_line('The count is '||bookset.count); --> I can see COUNT =1
      bookset := book_table(); --> Assigning back to NULL.
      dbms_output.put_line('The count is '||bookset.count); --> I can see count as 0
      select  book_obj(name,author,abstract)
        bulk collect
        into  bookset
        from  book;
      for i in 1..bookset.count loop --> Now Looping two times.
        dbms_output.put_line(' name > '||bookset(i).name);
      end loop;
      dbms_output.put_line('The count is '||bookset.count); --> I can see COUNT =1 (why)

• Retrieve all records in the selected master child multi tables

  Hello
  I use JDeveloper 11.1.1.4 version and using ADF - BC in my project.
  I have a one-to-one simple child master [several] in my project.
  In my view page, I display this master child [Ex: EmpVo1-> DeptVo2] in the form of tables.
  
  I have multi-selection enabled for the main table.
  My requirement is that, on the multi by selecting the lines in the main tables, I want to get all the child records in my grain of support.
  If a master has 3 child records line and another main line has 4 child records and on the selection of several of these two records in the primary table, I should get all the child records in my grain of support.
  I need it to implement the cascade delete feature.
  Here is the sample code coin
  --------------------------------------------
  
  (1) called on selecting rows in the master table
  
  {} public void onRSCGrpSelect (SelectionEvent selectionEvent)
  Add the code in the event here...
  ADFUtil.invokeEL ("#{bindings.") RscGroupVO1.collectionModel.makeCurrent} «»
  new class [] {SelectionEvent.class},
  (New Object() {selectionEvent});
  
  RowKeySet rowKeySet = (RowKeySet) tblRSCGrp.getSelectedRowKeys ();
  CollectionModel cm = (CollectionModel) tblRSCGrp.getValue ();
  
  for (object facesTreeRowKey: rowKeySet) {}
  cm.setRowKey (facesTreeRowKey);
  RowData = JUCtrlHierNodeBinding
  (JUCtrlHierNodeBinding) cm.getRowData ();
  Line = rowData.getRow ();
  System.out.println ("\n" +)
  row.getAttribute (0) + ":" + row.getAttribute (1) +.
  (":" + row.getAttribute (2));
  
  System.out.println ("display the child records");
  displayChildRecords (row.getAttribute (0));
  
  }
  
  }
  
  2 private void displayChildRecords (Object rscGrp) {}
  ViewObject rscMapVo = getRscMapViewObj();
  RowSetIterator rsI = rscMapVo.createRowSetIterator (null);
  While (rsI.hasNext ()) {}
  Line = rsI.next ();
  System.out.println ("\n" +)
  row.getAttribute (0) + ":" + row.getAttribute (1) +.
  (":" + row.getAttribute (2));
  }
  rsI.closeRowSetIterator ();
  }
  
  But the problem is that he is always giving me the last selected lines child details.
  
  Please suggest the error that I do.
  
  Thank you
  Praveen

  Your problem is to use makecurrent, which should not be used on a multi selection table. Then, if you have a relationship master detail you should have a view link between them. In this case, you can expose a method as you master to get the related child line. Not need to get the VO itself you can use the accessors of child iterator to obtain registration of the child.

  public void onRSCGrpSelect(SelectionEvent selectionEvent) {
  // Add event code here...
  RowKeySet rowKeySet = (RowKeySet)tblRSCGrp.getSelectedRowKeys();
  CollectionModel cm = (CollectionModel)tblRSCGrp.getValue();
  
  for (Object facesTreeRowKey : rowKeySet) {
  cm.setRowKey(facesTreeRowKey);
  JUCtrlHierNodeBinding rowData =
  (JUCtrlHierNodeBinding)cm.getRowData();
  Row row = rowData.getRow();
  //cast to the right row class
  EmpEmpVoRow empRow = (EmpEmpVoRow) row;
  // now you cann access the child row iterator
  RowSetIterator it = empRow.getDepVO();
  //now you cna iterate over the child rows
  System.out.println("\n" +
  row.getAttribute(0) + " :: " + row.getAttribute(1) +
  " :: " + row.getAttribute(2));
  
  System.out.println("Displaying Child Records");
  //use hte child rows here
  
  }
  
  }
  

  Don't know if the code compiles out of the box (do this on the train :-)

• Cannot open this file in the Adobe Muse site.  No record in the main.active table

  The title says it all.  Well well the error at least. I pulled some search terms in the error message and seem to have no luck through several search engines and of this forum.  HALP!
  Evelyn

  How the file last record? Where it has been stored? Was it ' Save As'ed ' on removable media that was then removed shortly after recording finished, perhaps without first be ejected from the operating system?

  This error indicates that the file is empty (all contents are gone). You will need to return on any backup copy you have. If the file is stored in a synced folder (e.g., Dropbox, Creative Cloud Files, GoogleDrive, Apple iDrive, MS a disk, etc.) these services generally provide access to all the old versions synchronized for a number of days.

• Why Skype keep going back to the status "available"?

  I'm running a Droid 2 Turbo with OS 5.1.1 on Verizon.
  My version of Skype is 6.15.0.1162
  I am also running Skype on my LG3 tablet, with the same questions.
  As a lurker, I always want to be among the invisible ones, but if someone sends me a message, or I restart one of my devices, I'm 'outstanding' status available so that the rest of the goobers on my contact list can see me, not to.mention family members I've been dodging for years.
  I saw where this was a problem for the desktop version and has been resolved with the last update. Y at - it's going to be a resolution for the mobile version as well, or do I have to find another application that allows me to hide the families feared?

  The statutes on Skype for Android are a mess of rush. An important thing to understand, is the status of the notification icon is completely meaningless. If she says 'Active', it means in fact 'Active', it means «the last time we checked, could be Twitter.com Active»
  
  Anytime the Skype window is not active or the screen is off, it goes 'inactive', but is not updated the icon and it stops, check his status, so he repeats to me 'Active' even if it is not. The only way to know what your status is, really, is to open the app window - which, after a few seconds, automatically turns the status "Active". This is absurd.
  
  Only the desktop version offers all control or reliability at all. I recommend to uninstall on Android and use it on desktop. Use other apps reliable messaging to the people you want to communicate with Android. Ask contacts for to add you other applications is a nuisance, but it's worth in the long term. Each version of Skype for Android is less reliable and more opaque than the previous.
