  Hello

  That's what you asked for in Oracle 10:

  SELECT       a.*
  ,       CASE
             WHEN  action = 'break'
             THEN  LAST_VALUE ( CASE
                                  WHEN  action = 'fix'
                                  THEN  author
                                 END
                                 IGNORE NULLS
                             ) OVER ( PARTITION BY  id
                                             ORDER BY      tmstmp
                                  )
         END        AS lastfixby
  FROM       actionhistory         a
  ORDER BY  id
  ,            tmstmp
  ;
  

  Like all of the built-in functions, LAST_VALUE is documented in the manual of the SQL language:

  Much more, it would help if you posted the request.
  It looks like you were using the old outer join notation (+). You can get the desired results by using an outer join with ANSI rating, but I think it would be more complicated and slower than with a LAST_VALUE.

  Concerning
  SAP

  Hello

  Your example of XML code is not correct, there is no LIST_G_ASSET element closing tag.
  But I guess that's not the real problem.

  the query always returns NULL for collumn1.

  The important thing to understand is that the paths that you declare in the COLUMNS clause are relative to the context item is past the main XQuery expression. He knows more about the rest of the document, in particular of his ancestors.
  In this case, you try to process a node whose absolute path would be

  /SA321/LIST_G_FAMILY/G_FAMILY/PARENT_FAMILY
  

  in a document which the node root is G_ASSET.

  The solution is to divide the query into two parts, the first one finds PARENT_FAMILY and the collection of G_ASSET and the second more shreds the collection G_ASSET is passed the first XMLTable in relational lines:

  SQL> SELECT x1.column1
    2       , x2.*
    3  FROM XMLTable(
    4         '/SA321/LIST_G_FAMILY/G_FAMILY'
    5         passing xmltype(bfilename('TEST_DIR','o5875854.xml'), nls_charset_id('AL32UTF8'))
    6         columns
    7           column1     VARCHAR2(50)  path 'PARENT_FAMILY'
    8         , assets      XMLType       path 'LIST_G_ASSET'
    9       ) x1
   10     , XMLTable(
   11         '/LIST_G_ASSET/G_ASSET'
   12         passing x1.assets
   13         columns
   14           column2 VARCHAR2(100) path 'ASSET_DESCR'
   15         , column3 VARCHAR2(50)  path 'EFFECTIVE_MONTH'
   16         , column4 NUMBER        path 'EFFECTIVE_YEAR'
   17         , column5 NUMBER        path 'ASSET_AMOUNT'

• ListField - how to get the selected items

  Hi @all,

  I am running OS5 on a BB bold 9700 and development via eclipse.

  I tried to do a listfield and put it in a display of network manager, which works very well.

  As peter_strange did in a reply to a thread listfield, I tried to catch the click button on navigation through "makemenu.

  It works fine, but after processing the code according to the listfield (getindex), it shows a standard menu, which I don't want. I want just to get the index or the name of the current or selected fields and continue with the transformation by showing a new screen for example.

  In some other threads that I found excerpts concerning 'navigationclick', but I don't understand, what I have to do here and why. Th KB, I searched but I did find something to go further.

  Someone there who can help me with a small example?

  Thank you much in advance.

  CUA

  You can create your own class or override her anonymously.

  I told you that replace the navigationclick() method where initialize you your listfield

  as I think that changing your code and then answer me

  _list = new ListField()
  {
  protected boolean navigationClick(int status, int time)
  {
    Dialog.inform("hi");
    return true;
  }
  
  public void paint(Graphics graphics)
  {
  graphics.setColor((int) mycolor);
  super.paint(graphics);
  }
  };
  

• How to get local values using the API of Java OLAP?

  http://download.Oracle.com/docs/CD/E14072_01/OLAP.112/e10794/overview-summary.html#Vals
  
  The third part of a unique value is the local value. In the previous example, the local value is CY2001, which is the identifier for the year 2001 in the overall scheme. Java Oracle OLAP API has the classes and methods that you can use to get the local values of dimension members. See the descriptions of the classes MdmPrimaryDimension and MdmDimensionMemberInfo for more information on the unique values and the.
  
  How to get local values for a dimension or hierarchy or a level using Java OLAP API?
  
  I can not find how...
  
  For example, I would like to get the list of members for each level (in my application: countries, States, cities)
  
  Thanks in advance,
  JP

  The following code assumes that you have an object MdmPrimaryDimension, dimension and a sense of routine, dumpCursor(), that takes an oracle.olapi.data.Source object.

  Find the objects of metadata
  Hierarchy of MdmLevelHierarchy = dimension.getDefaultHierarchy ((MdmLevelHierarchy));
  MdmAttribute localValue = dimension.getLocalValueAttribute ();
  The list of levels of = hierarchy.getLevels ();

  Print the members of each level
  for (MdmHierarchyLevel level: levels)
  {
  System.out.println ("Level" + level.getName ());
  System.out.println ();
  Source querySource = localValue.getSource () .joinHidden (level.getSource ());
  dumpCursor (querySource);
  }

  In general, it is more common to want to print descriptions of members. For this, you can replace

  MdmAttribute localValue = dimension.getLocalValueAttribute ();

  with

  MdmAttribute valueDesc = dimension.getValueDescriptionAttribute ();

  How would you say

  Source querySource = valueDesc.getSource () .joinHidden (level.getSource ());

  For the "description" and "local value".

  Source querySource = localValue.getSource () .join (valueDesc.getSource ()) .joinHidden (level.getSource ());

• How to get the peak value

  Can I know how to get the 2 peak values v1 and v2 and 2 duration times t1 t2.

  Since there is a small amplitude noise, difficult to use the Max simplely.

  May need to use a filter such as wavelets or TREE to Denoise it first. Can I know how to use, any Toolbox in labview. How do the curve smooth first.

  Thank you.

  I can't watch your vi now (I'm at work), but if your signals are long enough, you might consider a median filter.  You can set the number of points before and after use.  I found that it is useful for some smoothing problems (not all).

• How to get the value of a variant as a string

  I have an existing codebase, which transmits the values of the user interface to business logic as variants. I was prompted to connect all values passed in this way in a text file. I'm trying to figure out how to get the data as a string to a Variant value without having to deal on the type for the data descriptor. The flag variant the fact, so I think I can, too.

  

  Anyone know how?

  Thank you, all! I decided to use the XML approach:

  

• using PostDelayedCall how to get the value passed through void * callbackData?

  Can someone tell me how to get the data passed through void * callbackData?

  The following code, panel_ptr has the right address but still contains zero.

  void CVICALLBACK value_changed (void * callbackData)
  {
  int * panel_ptr;
   
  panel_ptr = callbackData;
  calculate_new_value (* panel_ptr);
  }

  int sign;

  Panel = 2;

  PostDelayedCall (value_changed & Panel, 0.2);

  The problem is using the callbackData parameter if it is a pointer, it must be a pointer to something which is still topical at the moment that the callback executes. That is to say, you cannot pass the pointer to a local variable in callbackData as when the callback executes the pointer is no longer valid. You can switch from its value, instead, in this way:

  ... SomeFunction)

  {

  int sign;

  ...

  Panel = 2;

  PostDelayedCall (value_changed, (void *) Panel, 0.2);

  ...

  }

  void CVICALLBACK value_changed (void * callbackData)
  {
  int panel_ptr;
   
  panel_ptr = (int) callbackData;

  calculate_new_value (panel_ptr);

  return;
  }

  There are many discussions on the forums on callbackData parameter that you might want to read.

• How to get the parameter values of a step type custom when I create file and adding a type of step seq

  I use lv 8.5 and teststand 4.0.

  I did a step type custom and recorded at the MyTypes.ini in pallets of type.

  I specified a default module by opening the properties of the custom step of *.ini type window, then I put some values of the parameters.

  T1) when I open teststand and I add the custom step type manaully in seq file, the labview module parameter values are represented.

  But, if to use file (create and add support prototype stage), the labview module parameter values has the default value.

  Using joint file, how to get the setting custom step type values I put in *.ini?

  Q2) each type of step are automatically by name through the use of LoadTypePaletteFilesEx. When I open teststand and I add the custom step type manaully in seq file, the module is loaded automatically. Inside the attachment, I use a prototype of charge and a fixed path where the module labview is to load the labview module.

  Can I load module automatically without using a prototype of charge or how can I get a dynamic path of type step?

  I solved Q1 for myself by using the mapping tab of the parameter within the configuration to the default module window.

  Everyone knows Q2?

  Thank you.

  How to get the product key I purchased previously?

  Depends entirely on how you bought it in the 1st place.

  A boxed product should have the key on the DVD case, which is the only trace.

  An update Anytime, you should have the key in an e-mail message from Microsoft. If you log in the website to store, you should be able to find the email conversation.

  If another provider such as a key, then you will need to go back to them.

  If your Windows starts now while you can use a keyfinder utility to read the registry key.
