Problem of null values for the Variable

• null value for the parameter in quesry

  Please help on this problem:
  
  I have a query like
  
  Select colA, colB
  from tableA
  where cola =: parameter;
  
  If: parameter has a value, then the request is ok for my pupposes,
  but when: parameter is null, then I have to choose only 3 values of colA. (ColA has more than 3 distinct values)
  
  I can't use nvl because there are 3 arguments and no 1.
  
  I tried:
  
  Select colA, colB
  from tableA
  where (: parameter is not null and colA =: parameter) or (: parameter is null and colA (1,2,3))
  
  but this isn't the solution.
  
  Can someone help me on this simple query?

  Your version must have worked as long as you have no other filter criteria in the where condition.
  Need you some parentheses around the OR condition. So I don't know what was the problem with your solution.
  BTW: There is a ') ' missing at the end, but I guess that it's just a typo while copying the code on the forum.

  The following alternative works:

  select colA, colB
  from tableA
  where colA in (nvl(:parameter,1) ,
               nvl(:parameter,2) ,
               nvl(:parameter,3)
               ) ;
  

  Advantage: Can be faster in the case of null, because it can always use an index on the column of cola.

• I am defining a recordset and he asked me a test value for the variable in form, anyone can tell me what variables would look like?

  

  In your illustration, he indicates that there should be a form variable which passes the value to the query. For example, if there is an input field

  Then, when the form is submitted, it will pass the value to the query.

  When you test the query in Dreamweaver, this value is unknown, where the question. Simply a response with a value and everything's fine.

• LocationProvider.getInstance returns a null value for the positioning of the cell PHONE location

  Hi guys.

  I'm having a problem trying to get a network of cells (MS basis) path to be able to work on my BlackBerry Bold 9000.

  Both assisted and Standalone GPS work (outside of course), but I'll try to find a way to position themselves inside the building.

  Here's what I'm going to put criteria:

  Criteria criteria = new Criteria();
  
  criteria.setHorizontalAccuracy(Criteria.NO_REQUIREMENT);
  criteria.setVerticalAccuracy(Criteria.NO_REQUIREMENT);
  criteria.setCostAllowed(true);
  criteria.setPreferredPowerConsumption(Criteria.POWER_USAGE_LOW);
  
  LocationProvider.getInstance(criteria); //<-- Returns null on real device
  

  When I run on a real device it gives me always null, when I do the same thing on a simulator, so this works:

  

  What I am doing wrong? I really need to find a way to make it work inside.

  Thanks for any input.

  Hey, Dominator,.

  I'll be real simple with you and try to make you save a LOT of time.

  Basically, cell tower positioning doesn't work out of the box on the Blackberry platform (except in a few configurations of rare device / carrier). So you can essentially throw the code you have above. If you need a place inside detection, you will need access to a database of celltowerId. These databases contain information from the Tower (Rad_error_nocontent, mnc, mcc, Lake) and its approximate location (lat/lng coordinates). This will give your application a rough estimate (less than a mile or two) from the current location of the device.

  Open source and professional databases are available. This is an open source database that runs on GSM networks (of course, he didn't 100% coverage of all the pylons). The biggest downfall is that it does not support CDMA (Sprint/Verizon) networks.

  http://openCellId.org

  You will find that most of the people on this forum are not very useful when it comes to cellTower information, positioning so you will need to research, research, research.

  Good luck

• How to value for the variable user massively

  Hello world
  
  Is it possible to massively value variable user, for example the currentVersion value variable user as 'Work' for all users instead of setting a preference?
  
  Thank you very much
  Van Huy.

  It kind of defeats the object if you want to set a user variable in the world and perhaps a substitution variable can be a better option.
  In any case, one option is to export the LCM user preferences, update the output and then import them into.
  If you want to take the risk of piracy tables then look at HSP_USER_VARIABLE_VALUE, HSP_USER_VARIABLE and HSP_OBJECT

  See you soon

• resolveNode returns a null value when a variable is used.

  LiveCycle Designer ES2, latest version

  Hello

  The following Javascript code, in the click event of a button, returns a null value for the variable opaque. When I manually enter the expected value the script works perfectly.

  I tried various modifications of the resolveNode line such as var opaque = xfa.resolveNode (qPage); , but without success.

  Also studied all the documents reference Adobe that I could find on the scripts and resolveNode. Any suggestions?

  var qPage = (Cell12.rawValue + "AnchorField");
  App.Alert (qPage);
  Opaque var = xfa.resolveNode ("' $... qPage '");
  App.Alert (opaque);
  var nPage = xfa.layout.absPage (opaque);
  App.Alert (nPage);
  xfa.host.currentPage = nPage;

  Thank you

  Ron

  I tried your sample and it seems to work very well... but I'm not sure 100% that you are trying to do... .going to your initial question on the passage of a variable in the resolveNode resolveNode expects a string, so you must use the following syntax to create the string:

  xfa.resolveNode ("$.." + qPage)

  Note that the variable is outside the quotes as such the string $... is added to the content of qPage. This wil work if qPage is a string as well.

  In your example you have defined qPage as an XFA object so that the syntax above will not work. If you intend to use the same way, you would use qPage.name so that the name of the field will be returned (this is a string) and it will be added to your expression of $ to make the $... ProductAnchorField

  Thus, the expression would be:

  xfa.resolveNode ("$.." + qPage.name)

  Make sense?

• NULL values for some elements of the XML reading tree

  I am confirming that I interpret correctly all the elements of a custom data XML structure defined by my application (the schema is completely under my control).  Some of the elements in my XML tree are read as NULL values, even if similar items are readind as expected.  I have checked some obvious things like misspelling the names of keys, but have not yet find the problem.  Anyone who has debugged similar questions - what else could cause this?

  Example XML:

  
      1.0.0.0
      1000
      MyAppsName
      
          
              1000
              userDefined
              StructName
          
      
  
  

  And extracted C++ w/comments at the end of each line about what I see (DataManager is my class of CRUD operations):

  In DataManager.hpp:

  QVariant mCustomDataStructsTopLevel;
  QVariantMap mCustomDataStructsTopLevelMap;
  

  In DataManager.cpp:

  mCustomDataStructsTopLevel = mXda.load(Utils::dataFilePath(customDataStructsFileName));  // XmlDataAccess; verified loading w/no errors
  mCustomDataStructsTopLevelMap = mCustomDataStructsTopLevel.toMap();
  
  qDebug() << "appName element value: " << mCustomDataStructsTopLevelMap["appName"]; // Outputs "MyAppsName" as expected
  qDebug() << "lastId element value: " << mCustomDataStructsTopLevelMap["lastId"]; // Outputs null (specifically: QVariant(, ) ) - this is NOT expected
  qDebug() << "appVersion element value: " << mCustomDataStructsTopLevelMap["appVersion"]; // Outputs null (specifically: QVariant(QString, "") )  - this is NOT expected
  

  OK, I got the feeling (and actually hoped) it was a silly mistake of face-palm on my part (compared to a problem of BB10 who had little chance of getting fixed).

  The problem is that I copy the structure of custom data from Starter to my Active dir to my data directory to first install but do not crush him on subsequent launches, as the copy in the data directory is what the user changes and relies on.  I was not a delete and reinstall on each of my iterations, so I wasn't really loading the modified versions of my XML I wanted--just, I was getting a day old stale version which was actually for the items I didn't expect NULL values for nulls.  DOH!

• Null values for DB2 are causing problems

• Save the value of the variable on rising

  Hello

  My setup is quite complicated (and does not work properly yet)... anyway, I give all of the code.

  What interests me now is to learn how to save for later use the value of the variable 'Bias' on a rising "min. . found.

  The 1st idea coming is to create another case of event for changes "min. Found" , where to save in a registry change, but the problem is "min. Found" changes fires on the edges and falling .

  Thanks in advance

  Pavel

  

  Pavel_47 wrote: but the problem is "min. Found" changes fires on the edges and falling .

  It's actually worse than that.  Change value Min found fires with all writing, regardless if the value has changed or not.  It's one of the dangers of the use of the Value property (signs).

  Do a Boolean search PtByPt crossing.  It's a useful for this situation VI.  It will display a TRUE with the edge that you tell him.  After that, just use a case structure and make any desired calculations in it.

• [ADF, JDev12.1.3] (How to set values for the attributes 1) to create a file and 2) committing to the database?

  Hallo,

  in my tables and forms (created from VO istances) there are some areas for which, insert and update, I calculate and set the value programmatically when a record is created or updated.

  In some cases, I put the necessary values using the 'CreateWithParams' in the workflow diagram...

  

  In some other ones, I associate an action, a bean, a created button drag-and - drop operation 'CreateWithParams' of the istance VO...

    public String cwpButton_action() {
      BindingContainer bindings = getBindings();
      OperationBinding operationBinding = bindings.getOperationBinding("CreateWithParams");
      // here I calculate and set the needed params
      // ...
      Object result = operationBinding.execute();
      if (!operationBinding.getErrors().isEmpty()) {
        return null;
      }
      return null;
    }
  

  And is ok if I can calculate the values for the attributes before a new record is created.

  But the approach that I have used to define the attributes (for new and updated records) whose value should be caluclated after the user has filled in the fields, before committing to the database?

  Thank you

  Federico

  Federico,

  Let me first tell you that our code is activity masking errors (the cache instead of working on them).

  1. If (! operationBinding.getErrors () .isEmpty ()) {}
  2. Returns a null value.
  3. }
  4. Returns a null value.

  This means that you do not check the errors at all. You must at least print a log with the error message, you receive, if you get one!

  To solve your problem, you override the method prepareForDML() of the entity or entities in question. You can calculate and set the necessary attributes until they get engaged in the doDML(). Do not use doDML() because it is too late in the life cycle.

• Need to null values with the values of filling the date before weekend/holidays

  I have a table with a Date column, column Type and rate column.

  What could I do?

  Hello

  You can use the analytic LAST_VALUE function to get the last day of work before each date into your table. It will be the same as the current day for every day of work.
  Do it a self-join to combine each current line (c) with the last day of work (l):

  WITH     got_last_work_day     AS
  (
       SELECT     dt, type, rate
       ,     LAST_VALUE ( CASE
                      WHEN  type  IS NOT NULL
                      THEN  dt
                     END
                     IGNORE NULLS
                    ) OVER (ORDER BY dt)     AS last_work_day
       FROM     table_x
  )
  SELECT       c.dt, l.type, l.rate
  FROM       got_last_work_day     c
  JOIN       got_last_work_day     l  ON       (    c.dt          = l.dt
                           AND  c.type          = l.type
                           )
                         OR     (    c.last_work_day     = l.dt
                           AND  c.type          IS NULL
                           )
  ORDER BY  c.dt
  ,       l.type
  ;
  

  Among other things, I guess that the type is NULL if (and only if) the line represents a holiday or weekend, and that the combination (dt, type) is uniuqe.
