• SQL, find the MAX value and placing it as a QVariant

  I have a database that is loaded and defines the customerID as 0 which is ideal when the database is not be saved and restored, etc.  The question I have is that I added the possibility to users to restore a backup in the app, and now I have to do a query to select MAX (customerID) so that there is no duplicate CustomerID when you add or save items.  Here is the following code, I knew that I must settle, specifically the 0 highlighted in red.  I need zero to be the new customerID max value:

  int SettingsStorage::load(int& lastID, GroupDataModel *model)
  {
      // number of locations loaded.
      QSettings settings(m_author, m_appName);
      int loadedCount = 0;
  
      QVariant items;
      // Get the last customer id first.
      // ID's will be generated by incrementing this number
      // Note values coming from settings should be cast to the
      // required type.
       lastID = settings.value(m_lastCustomerIDKey, 0).toInt();
      items = m_sda->execute("SELECT * from items ORDER BY datefield");
      qDebug()<< "the ID" << items;
      // Load all the locations from the database.
      foreach( const QVariant& temp, items.value() ) {
          Location *p;
          if (loadLocation(temp.value(), p)) {
              model->insert(p);
              loadedCount++;
          }
      }
      return loadedCount;
  }
  

  Ive tried the following, but it doesn't seem to do anything:

  int SettingsStorage::load(int& lastID, GroupDataModel *model)
  {
      // number of locations loaded.
      QSettings settings(m_author, m_appName);
      int loadedCount = 0;
  
      QVariant items;
      // Get the last customer id first.
      // ID's will be generated by incrementing this number
      // Note values coming from settings should be cast to the
      // required type.
       QVariant endID = m_sda->execute("Select MAX(customerID) from items")
       lastID = settings.value(m_lastCustomerIDKey, endID).toInt();
      items = m_sda->execute("SELECT * from items ORDER BY datefield");
      qDebug()<< "the ID" << items;
      // Load all the locations from the database.
      foreach( const QVariant& temp, items.value() ) {
          Location *p;
          if (loadLocation(temp.value(), p)) {
              model->insert(p);
              loadedCount++;
          }
      }
      return loadedCount;
  }
  

  Any help will be loved and marked solutions.

  -Thanks in advance

  I was wrong about executeAndWait(). Somehow, I decided that you use the SqlConnection object, but seems his SqlDataAccess. So disregard my previous post. Keep your execute method, but you must change your code to something like this:

  QVariant endID = m_sda->execute("select max(customerID) as m from items");
  
  QVariantList vlist = endID.value();
  QVariantMap vmap = vlist.first().toMap();
  
  lastID = vmap["m"].toInt(&ok);
  

  So I changed your SQL query slightly and added "that m" so I will have something to refer later.

  Then I cast QVariantList because it is where are the results.

  Then because we know its going to be the only record, I took the 1st element in the list and converted to QVariantMap.

  Last step is to get the maximum.

• How to get the physical channel for USB card as ENET

  Hello

  For my application (VB .NET, using NIDAQmx 8.8), I need to access the 2 cards:

  a USB-6008 and an ENET9163.

  I would like to read the physical channels automatically with this feature NI-DAQmx

  Physicalchannel1ComboBox.items.AddRange (DaqSystem.Local.GetPhysicalChannels (PhysicalChannelTypes.AI, PhysicalChannelAccess.External))

  Unfortunately, he didn't get a single card at once.

  When the USB card is connected, he read the physical channels of the USB card

  When the USB adapter is not plugged in, it read the physical channels of the ENET card.

  I hope someone can help me with this problem!

  Thank you

  RB

  Hello RB.

  To read from multiple channels, you can enter in the drop-down list box "Physical channel", the comma separated channels, custom channels or if you read physics, the string "DevX/Benjamin: Z", where X is the number of device, and X and are the first and the last channel you want to analyze (for example to read to ai0 to ai4 from your device 1 enter "Dev1 / ai0:4"). Among the names of your channels, I guess they are global channels created in MAX? You can always read channels multiple and different advice by separating the comma.

  I hope this helps!

  Kind regards

• MAX values and null

  Hi all, I have the following query
  

   SELECT prod,id,max(payment_date) payment_date        
          FROM balance
            WHERE run          = 25
              AND pdate   = '07-sep-2012'
              AND cd='CFACILITY'
              AND prod IS NOT NULL
              AND id IS NOT NULL
              AND payment_date IS NOT NULL
            GROUP BY prod,id

  I am rewriting the query so that I do not have the IS NOT NULL in the where clause. Depending on the size of the table, it causes the performance issue.
  is it possible to rewrite the query so that I don't have a filter to help do IS DO NOT NULL, but at the same time producing a correct result in leaving aside the null lines.
  for example, I am trying to eliminate:
  AND prod IS NOT NULL
  AND id IS NOT NULL
  AND payment_date IS NOT NULL
  at the same time I would like to use an analytic function or other technique to filter the data and get the lines which are not null in the select. don't know if I can filter for not null by using the analytic function
  
  Maybe the analytical function will do. any idea?

  You can put all these conditions in a HAVING clause:

  WITH
  SELECT prod,id,max(payment_date) payment_date
          FROM balance
             WHERE run     = 25
               AND pdate   = '07-sep-2012'
               AND cd      = 'CFACILITY'
             GROUP BY prod,id
             HAVING   prod          IS NOT NULL
               AND    id                 IS NOT NULL
               AND    MAX (payment_date)  IS NOT NULL
  

  Normally, when there is a choice between the filter in the WHERE clause or the HAVING clause, the WHERE clause is faster, but maybe it's an exception.

  If a group contains a few payment_dates NULL, which is not serious. MAX gets back the last payment_date not NULL and ignore all nulls. The only time where worry is if all the lines in the Group had payment_dates NULL, and the latter in the HAVING clause takes care of this.

  What is the data type of p_date?
  If it is a DATE, then don't compare it to a VACHAR2, such as "- 7-sep-2012". Use rather a literal DATE or TO_DATE.
  For example:

  AND pdate   = TO_DATE ( '07-sep-2012'
                            , 'DD-mon-YYYY'
                  )
  

  Depending on your data and your needs, which may not work. If p_date isn't always midnight, then you should probably do something like this:

  AND TRUNC (pdate)   = TO_DATE ( '07-sep-2012'
                                   , 'DD-mon-YYYY'
                       )
  

  However, it is inefficient. It would not be faster to call TRUNC and do this way:

  AND pdate   >= TO_DATE ( '07-sep-2012'
                        , 'DD-mon-YYYY'
                   )
  AND pdate   <  TO_DATE ( '07-sep-2012'
                        , 'DD-mon-YYYY'
                   ) + 1
  

  Maybe the analytical function will do. any idea?

  I don't think, but maybe I'm missing something. What was your thinking? Why suggest analytical fucntions?

  Depends on how you feel on one of the links of:

  SELECT name, value
  FROM (SELECT name, SUM(value)
        FROM table
        GROUP BY name
        ORDER BY 2 DESC)
  WHERE rownum = 1
  
  SELECT name, SUM(value)
  FROM table
  GROUP BY name
  HAVING SUM(value) >= ALL (SELECT SUM(value)
                            FROM table
                            GROUP BY name)
  

  among many other methods. The first takes a single arbitrary registration in the case of a tie, and the second shows all the related records.

• How to get the value of prompt financial reports and use it as a header

  Hi gurus of the Oracle,.
  
  I have Hyperion Financial Reporting 11.1.1.3. I've created a report.
  
  I have the Products dimension on rows. And I also fast for the products.
  
  Let's say there are 3 products, product A, B and C, each has its own point of level 0 (for example, A1, A2, B1, C1)
  
  Currently in my situation, user will be prompted to select a list of products, and then the report will only show the level 0 of the product selected by the user. For example, the user select product has, then the report (or grid) displays A1 and A2 on the ranks. The user select product B, B1 will be displayed.
  
  My question is, I want to create a dynamic header report, so how can I get this prompt value and use it as a report header? For example: sale of product when the user choose the product, or sales of product B when the user choose produced B.
  
  
  Thanks a lot for your answer.

  Hello

  Here's the way to do this:
  1 insert a line (can be in line 1) in the report that produced as 'ask the user.
  2 always mark this as hidden line
  3. the user other lines like Level0 of product online 1
  4 use MEMBERALIAS in the header to use the product as dimension & row as row1

  It could be useful!

  }
  

  Now, I'll put the element as follows:

  SaiPersistentStore.getInstance (.setElement("Registration","on"));

  But when I try to get the item in a way theis, gettting null value:

  SaiPersistentStore.getInstance () .getElement ("Register")

  Where I am doing wrong here?

  The fixed. Key hash table was different. Change it and it works...
