• Help the insertion of an unknown number of lines in a custom Data Type

  Hi all
  
  I need help in the insertion of an unknown number of lines in a custom Data Type
  
  In Oracle I was thinking something like...
  

  CREATE OR REPLACE TYPE &HKDB_Schema_Name..SOMEDATA AS OBJECT (ID int, Name varchar2);
  /
  CREATE OR REPLACE TYPE &HKDB_Schema_Name..TYP_TABLE AS TABLE OF &HKDB_Schema_Name..SOMEDATA;
  /
  
  CREATE OR REPLACE PROCEDURE &HKDB_Schema_Name..SProc1
  (
  )
  AS
  l_TempTable TYP_TABLE := TYP_TABLE();
  v_count NUMBER := 0;
  l_ID int;
  l_Name varchar2(200);
  BEGIN
   
    LOOP
    -- exit the loop if the select returns no results. (look if exists in l_TempTable)
    v_count := SELECT COUNT(*) FROM Person p WHERE p.ID NOT IN (SELECT ID FROM TABLE(CAST(l_kgListTable AS TEMP_KGID_TABLE)));
  
    -- select the top result
    SELECT p.ID, p.UserName INTO l_ID, l_Name FROM Person p WHERE p.ID NOT IN (SELECT ID FROM TABLE(CAST(l_kgListTable AS TEMP_KGID_TABLE)))  
    AND ROW_NUM = 1;
  
    insert data into custom data type
    l_TempTable.extend;
    l_TempTable(l_TempTable.last) := SOMEDATA(l_ID, l_Name);
  
    EXIT WHEN v_count < 1;
    END LOOP;
  END SProc1;

  While I don't know this will probably do the job, it feels not very effective, have to select where the argument no_lig = 1 and then insert a facility on time. Is there a better way to do it?
  
  Basically, it's a migration of a MSSQL stored procedure where the equivalent would be...
  

  DECLARE @TempTable TABLE (ID int, Name varchar)
  
  INSERT INTO @TempTable (ID, Name) (SELECT ID, UserName FROM Persons)

  Thanks in advance,
  Toby

  Oh sorry you posted that before but I missed it. In this case maybe you should simply remove the

  as "HasChildren"{pre} part. This is only valid for a column name, but you input that expression directly into a type. It is not a column at this point.

  Usually the easiest way to get data out of unifier is to create a UDR who has the specific data that you want and then you can use the web service getUDRData. Having a UDR allows to choose the fields specific (or just the top shape in your case), and to put in place filters you can (registration State,...).

• How to make your custom data type used in your QListDataModel to QML?

  I have QListDataModel filled with objects of a custom class carying data and defined with Q_DECLARE_METATYPE. So far, it works however I can't access the data in qml:

  e.g. text: ListItemData.Name
  

  I read that this can be solved by letting QML know your custom class/type, but how to do this?

  See

  example:

  qmlRegisterType("com.isec7.materials", 1, 0, "Account");
  

• How to delete several lines in the details Table with PRIMARY KEY = ("VID", "LINEITEM")?

  Mr President

  My worm Jdev is 12.2.1.

  I have master tables / details.

  I have 2 lines for each PRIMARY KEY = ("VID", "LINEITEM") as below in the Details table.

  

  Please help how to get a button on a jsf page to remove these two lines at a time.

  Concerning

  So, in your app (data model) module, you have a master relationship / typical retail:

  

  And the relationship between them is based on some ViewLink

  Now go to the ViewLink, relationship, accessor.

  Take a look at the Destination accessor.

  Generate accessor object to check and give a name Acessor

  

  Then go to the master VO, Java and Include accessor, the class generate a display line:

  

  Go to the class view Java generated line, you'll find a method with the name of the accessor of the previous step, in the form of:

  public RowIterator getYourDetails...or_whaterever_IsAccessorName..() {
  }
  

  Now, in the same Java class, write the following Java method:

  public void removeDetails(){
    RowIterator details = getYourDetails...or_whaterever_IsAccessorName..(); // it is RowIterator over all details
    Row r = details.first();
    while (r != null) {
        r.remove();
        r = details.next();
    }
  }
  

  This method on the Cilent export line Interface:

  

  Finally, pass the data controls and drop this operation on the form as a button...

• You press on delete all selected items by browsing the data store and accidentally deleted a vmdk file which has the OS on it

  I accidentally deleted the vmdk file that has my OS on it by pressing the "Delete selected items" button in the window of browser data store. Is there anyway to recover? I have a snapshot that doesn't seem to work. There is still the VMDK file in there, but it has now 'delta' be added at the end. Now I get an error message when I try to turn on my VM saying that he doesn't get the vmdk file, of course.

  

  

  From the screen shots looks you have deleted only the descriptor hard files that can be recreated. To ensure this is the case, please provide a complete list of the files in the folder of the virtual machine and attach the last file.log of vmware(from the virtual work computer) to a post response to view required details.

• deleting several lines in a report?

  db11gxe, apex 4.0, firefox 24,

  How to delete several lines in a report at the same time?

  Thank you

  Hi newbi_egy,

  Here's a demo with a few steps that can be used in your scenario-

  (1) this is the query for a report on the emp table that has column empno with values single-

  SELECT APEX_ITEM.CHECKBOX(1,empno) " ", ename, job FROM   emp ORDER  by 1
  

  (2) a button Delete is created that submits the page.

  (3) a sur-soumettre the process is created with point process on submit - after calculations and Validations to determine that the sub process is running when you click the button remove.

  BEGIN
  FOR i in 1..APEX_APPLICATION.G_F01.count
  LOOP
  delete from emp where empno=APEX_APPLICATION.G_F01(i);
  END LOOP;
  END;
  

  I hope this could help you.

  Kind regards

• How will I know where the time goes when you delete a line?

  Dear experts,
  
  Removal of certain rows in a table (approx. 4.9 GB / 2.9 Millon lines) takes an average of.5 seconds each line (on average).
  
  This table contains 3 clues, just I just rebuild. Statistics from a couple of the day before.
  
  I have imported/exported the table to a new schema and destruction prend.002 seconds each line (on average).
  
  How will I know where the time goes when you delete a line?

  Yes, is there some sort or an easy way to do it?
  
  Is anyway to do this in a single sql statement? I guess not. Correct me if I'm wrong :-)
  
  Thanks in advance!

  Yes. You can use the same approach in Oracle parallel query processing.

  Simplistically - a table has a data block and a block of data end start. You can calculate the physical address of the lines for a row of this table in the starting block. Similarly, you can calculate the last address of a row of this table in the end data block.

  You divide the range of data block start and end in several beaches - where each line has an equal number of data blocks. Assume that the table includes a 1000 data blocks. We create 5 ranges, each with 200 data blocks. Now, for each of these lines, we can determine what would be the rowid (physical address lines) for the first and last lines to this range of data block.

  We take our original SQL that will hit most of the lines in this table:

  delete from fooTable where col_n = :filter1
  

  We add a rowid range predicate to it:

  delete from fooTable where col_n = :filter1 and rowid between :1 and :2
  

  We can now start 5 process (in series or parallel) and to provide each of these with the physical ROWID calculated for 5 lines. Thus, each SQL get 200 blocks of data to deal with. As opposed to a single SQL that would have made all the data blocks of 1000.

  This approach only works if the SQL is similar to a full table scan - this means that your SQL will probably hit most of the lines in this table.

  Basic code for this approach was published in [this thread | http://forums.oracle.com/forums/thread.jspa?messageID=1534900#1534900]. (ignore the smiley in the code, which is assumed to be zero bindvariable, but is now rendered differently by the new version of Jive)

  put the parameters in a map before the table target, connect them with the target table, configure the type of loading of the table to delete, game by constraint: constraint, select the table col1, don't configure it: match when removing = Yes, same for Col. 2. Deploy and run the mapping.
