• Data model - dynamic query with parameters

  Hi friends, is it possible to dynamically call a query using the parameters of the data models?
  
  I try to have a BEEP report with data model something like that
  
  Data model
  Param1
  
  Q1 = Select * from table 1
  Q2 = Select * from table 2
  
  If Param1 = X then
  FinalQuery = Q1
  On the other
  FinalQuery = Q2
  End
  
  Any help is greately appreciated.
  
  Thank you
  SAI.

• How to pass parameters to Date on the data model

  Hi all
  I try to pass parameters of date on the data model and unable to pull all the data. When I tried hard-coded in the SQL query, it works. Here is the data model, can I pass parameters directly to the dataquery?
  I searched a lot but couldn't find it. Any help is greatly appreciated.

• Multiple datasets in single data model

  Dear experts,

  We have created a unique data model that has several sets of data sharing common to BI 11 g Publisher parameters.

  We are facing a problem of performance (data recovery is very slow) while to fetch data from database on execution.

  How to improve the performance in this case?

  Your help will be very appreciated.

  Thanks in advance!

  DB BLOB data recovery should not be a problem. But just to make sure that you remove your SQL BLOB type and see to it there improvements?

  Unfortunately I can't find any documents which mention the process of execution of the data sets.

  But you can do a proof for yourself:

  Add sysdate with timestamp on each set of SQL data and you can see the date with timestamp in the output xml (data view tab) which will show you what set of data is performed first and then what that and etc...

  It will be executed in the order of your data set creation. You can see the structure of the data set in the Structure tab.

  Have you considered the approach below?

  I recommend you to do.

  Is there is no adjustment to make in your SQL, then you can use triggers of events (before the data type).

  You can create a package that runs your sql DB and insert the data into a temporary table and then just ask the temporary table on the data set.

• Export file DDL in SQL Developer Data Modeler

  I export my last project of relational model of the DDL weeks in hopes of getting a quick and precise way to create my 17 tables. In the relational model, Cust_ID is the PK yet there is nothing indicating it in the script that is created from the export file DDL.  That's what he created.  Now, when I right click on the customer table in the view of the relational model and then choose Preview DDL, it adds the line of alter table. But when I do this for most of the opther whose phones table tables in the image below, it's just the fields, no PK or PK info. How can I get the PK and FK stand? Thank you, Peter

  CREATE THE customer TABLE

  (

  Cust_id INTEGER NOT NULL,

  Name VARCHAR2 (128).

  Address VARCHAR2 (128 CHAR)

  ) ;

  ALTER TABLE customer ADD CONSTRAINT Customer_PK PRIMARY KEY (Cust_ID);     <-this is displayed in the preview of the DOF, not export file DDL. The telephone table does not show the constraints or keys in each view. Even with almost all tables.

  That's what I have for phones

  CREATE TABLE phones

  (

  Phone_ID INTEGER NOT NULL,

  Phone_Type NVARCHAR2 (10),

  Phone_Number TANK (14),

  Customer_Cust_ID INTEGER NOT NULL

  ) ;

  

  Hi Peter,.

  A couple of points to check for definitions of key primary and missing foreign key:

  1. the relational model for the primary keys and foreign keys dialogs have both checkboxes 'Generate in DDL', which are normally set.  Make sure they are always defined.

  2. When you make a DDL generation, on the generation of DDL Options screen, select the PK tabs and UK and foreign key constraints and check the boxes 'Selected' for relevant pharmacokinetics and the FKs are defined.  (These settings are remembered from one generation of DDL to the other, and an overview of the DDL will normally use the same parameters as the most recent generation of DDL).

  What Data Modeler version do you use?

• Increased support of Type of object in Data Modeler

  Hello
  
  It is a matter primarily for the development team to shape data as well as the Group of tools. First of all, the production of Data Modeler 3.0 version is very nice and improvements in data types on which was in EA1 are large. Thanks for adding to the support of the domain to the definition, attributes and parameters for methods which makes life much simpler and opens the door to a range more wide object type modelling and ease of implementations because consistency can now be maintained much easier through areas. Support for the smoothing of lines is also impressive. It is the best app that I've seen, even better than what we had in the Design Editor in the Oracle Designer, Bravo still once the team which built the diagrammer interfaces.
  
  My question is, going forward will be Data Modeler has continued to be improved to fully support the Oracle objects and object relational (OR) model? I ask this question because as users of Oracle RDBMS, we do not have a tool that allows to fully model and implement the functionality provided by the server group in the field of object-relational features. Oracle Designer had a capacity of modeling of GOLD, but the end of the product life has stopped any further development. One of the common excuses is there is no request for the market for object - relational modeling. I would say, that the absence of the market demand for object - relational applications is because we have never had a tool that fully supports the relational Oracle - model object. Nor do we have a development tool that allows us to implement a fully developed relational Oracle - model object. The Tools group stopped the development of Oracle Forms support for nested objects and collections. The LOV REF columns feature is quite impressive, but we are unable to get nested collections, still less a nested collection of REFs.
  
  So as a member of the end user community, we are stuck in this Catch 22. The server group continues to support and improve the object - model relationship, but the tools and modelling groups have not kept with the tools to model or to implement the features and the features supported by the database. As a result, we have a partially constructed set of tools that allows you to scratch the surface of the object - model relationship, but is not able to take full advantage of the powerful features of legacy, legacy and extensive collections, the ability to inherit and extend methods, etc...
  
  The object - relational model introduced with Oracle8, 10g solved the problem of evolution of type which has made the implementation of the production of realistic objects. My question is; Data Modeler is finally going to fully support the relational Oracle - model object? If until the end user community, we finally get a tool that totally supported the model of GOLD, finally, we will be able to model, generate and deploy applications that will in turn create this market demand which is lacking for the relational model object.
  
  Thanks in advance,
  ACE

  Hi Ace,

  Thanks for the good words.

  will be the Data Modeler has continued to be improved to fully support the Oracle objects and object relational (OR) model?

  Short time - Yes. What do you want Besides lack of support now nested columns (and related to these constraints, including the PK constraint) and the generation of the 'Alter Instructions?

  Please suggest how do...
  Made a package with the PARAM_THRESHOLD_VALUE parameter and the function value entry assigns the done variable to work?
  
  Thank you
  Shiva

  Hey Shiva,

  If you want to use the value of the counter in the other queries in the data model, you can have an alias for the extraction of County and use it as a bind variable in other queries as

  
  SELECT count (*) PARAM_THRESHOLD_VALUE
  FROM TABLE_NAME
  ]]>
  

  and can use it in another query as

  
  SELECT XYZ
  FROM TABLE_NAME2
  WHERE XXX = *: PARAM_THRESHOLD_VALUE *.
  ]]>
  

  Hope this is what you want.
  Thank you.

• Is it possible to make the condition depending on the sql statements in the data models

  Hi all
  
  Is it possible to include the condition based on sql statements in the data models.
  
  For example

  if (some parameter is not null)
  <sqlstatement name="STATEMENT_1">
  ...
  </sqlstatement>
  else
  <sqlstatement name="STATEMENT_2">
  ...
  </sqlstatement>

  Is something like this? Also, the good doc is available for ' how to take full advantage of the "data models" in BI Publisher?
  
  Thank you
  -Sookie

  Hello Sookie,
  I couldn't find the time to get a data model of demonstration of work for you, but I'll try to explain.

  First, write a PL/SQL package. Make sure that you set all the parameters of model of data such as a global variable in the default PL/SQL package.

  CREATE OR REPLACE
  package as employee
  function BeforeReportTrigger return Boolean;
  query_text varchar (2000);
  number of p_DEPTNO;
  END;
  /

  CREATE OR REPLACE
  package as body employee
  function BeforeReportTrigger return Boolean IS
  Start

  IF (p_DEPTNO = 10) THEN
  query_text: = select col1, col2, col3 from HR.
  elsif (p_DEPTNO = 20) THEN
  query_text: = select col1, col2, col3 hr_history.
  on the other
  query_text: = select col1, col2, col3 hr_history1.
  end if;
  Returns true;
  end;
  /

  Use this package in the default package in your data model. Check the "defaultPackage ="employee"in the following data model header.

  Sample data model
  ------------------------------

  Before running the query SQL, data engine reads the "before the release of the report" and all the texte_requete argument based on the p_DeptNo value. When executing the Q1, engine sqlQuery analyze the query ' & quert_text and replace it with the actual value. For example if the p_deptno = 10, the query will be "select col1, col2, col3 from HR.

  Now I am faced with two questions.
  (1) when I select "All" from the LOV and try to view the report there is no counter code be passed as a parameter. When I select "All" in LOV the XML that is generated, that's how.
  
  <? XML version = "1.0" encoding = "UTF-8"? >
  < Enonce1 >
  < > 000 BRANCHCODE < / BRANCHCODE >
  < / STATEMENT1 >
  As you can see he is just passing the value defined as defaultValue in the data model.
  
  (2) when I select several entries of LOV they demonstrate them as parameter in XML, but no data is returned. Resulted in the XML is like that.
  <? XML version = "1.0" encoding = "UTF-8"? >
  < Enonce1 >
  < BRANCHCODE '000 ', '001','002 ' > < / BRANCHCODE > (these are the parameter values)

  Hello

  you need a lexical parameter in your query:

  SELECT DEPTNO, DNAME, LOC FROM DEPT * & deptwhereclause *.

  This glossary can be defined in one before the report according to your setting of multiple selection

  If p_deptno is not null then
  deptwhereclause: = ' WHERE DEPTNO IN ('| p_deptno |') ' ;
  end if;

  This complete example is here: http://www.oracle.com/global/de/community/bip/tipps/dynamische_queries/index.html

  It's in German, but the screenshots and code may help anyway.

  What is the right way to make a lexical reference? But if I use a single table as example only emp. I get the data correctly without error... when I joined in the clause where I found myself with an error message saying not properly completed sql statement...
  
  Where could I go wrong... Pointers...
  
  Thanks in advance...

  Hello

  your query in the data model is
  SELECT EmpNo, deptno FROM emp, dept where emp.deptno = dept.deptno & whereclause

  Now you define whereclause in the package as follows:
  WhereClause: = ' where empno in ('| p_emp_id |') ' ;

  which translates
  SELECT EmpNo, deptno FROM emp, dept where emp.deptno = dept.deptno where empno...

  that is a request not valid.

  Try in your package with
  WhereClause: = ' and empno in ('| p_emp_id |') ' ;

  In another part of my application, I use an activity indicator to load a webView but I couldn't reshape it for the list view.

  The following code works when my webView loads:

  WebView {
                      id: detailsView
                      settings.zoomToFitEnabled: true
                      settings.activeTextEnabled: true
                      settings.background: Color.Transparent
                      onLoadingChanged: {
                          if (loadRequest.status == WebLoadStatus.Started) {
  
                          } else if (loadRequest.status == WebLoadStatus.Succeeded) {
                              webLoading.stop()
                          } else if (loadRequest.status == WebLoadStatus.Failed) {
  
                          }
                      }
                      settings.defaultFontSize: 16
                  }
  

  Container {
              id: loadMask
              background: Color.Black
              layout: DockLayout {
  
              }
              verticalAlignment: VerticalAlignment.Fill
              horizontalAlignment: HorizontalAlignment.Fill
              Container {
                  leftPadding: 10.0
                  rightPadding: 10.0
                  topPadding: 10.0
                  bottomPadding: 10.0
                  horizontalAlignment: HorizontalAlignment.Center
                  verticalAlignment: VerticalAlignment.Center
                  ActivityIndicator {
                      id: webLoading
                      preferredHeight: 200.0
                      preferredWidth: 200.0
                      horizontalAlignment: HorizontalAlignment.Center
                      onStarted: {
                          loadMask.setVisible(true)
                      }
                      onStopping: {
                          loadMask.setVisible(false)
                      }
                  }
                  Label {
                      text: "Loading Content..."
                      horizontalAlignment: HorizontalAlignment.Center
                      textStyle.fontSize: FontSize.Large
                      textStyle.fontWeight: FontWeight.W100
                      textStyle.color: Color.White
                  }
              }
          }
  

  onCreationCompleted: {
          webLoading.start()
      }
  

  Therefore, what I am trying to make is: get the activity indicator to show when the list view is charging and when it's over, for the activity indicator be invisible. Also, if the user doesn't have an internet connection or loses the signal while the data is filling: would it be possible to recover data from a file stored locally instead ("asset:///JSON/Fixtures.json")?

  Thanks in advance

  With the help of a few other developers I maneged to make everything work properly.

  Jeremy Duke pointed out that I would need to use the onItemAdded in my data model of the Group:

  onItemAdded: {
                          myActivityIndicator.stop();
                          myActivityIndicator.visible = false;
                          loadMask.visible = false;
                          searchingLabel.visible = false;
                      }
  

  Adding that, the loading stops when an element has completed the list.

  Thanks for your help

• Group data model does not

  Hello

  I am developing a revision update for my app BB10 stunts and I use a data model to pull in the elements of the application do not forget; the only problem I encounter is that I can't get the data model of the group work so that I can arrange the items by the first character instead the data are currently presented as Z - A, even if I could get it to display in A - Z would be enough, but what I am looking to achieve is to get the model to display in A - Z and then sort by the first character, while a header for each letter is displayed.

  If something you can help me with then this would be very useful - if you need to see more of code then let me know too!

  Thanks in advance

  Try to add in constructor (after a call to setGrouping):

  QStringList keys;
  key<>
  m_model-> setSortingKeys (keys);

  May require alterations, I have not tried this compilation.

• Get the first item in the data model

  I'm trying to get the first item in a data model. I expect the following to work, but it returns-1

  var firstItem = myDataModel.indexOf(0)
  

  Row is a table, and data() must return a specified row element:

  if (myDataModel.size() > 0) {
    var firstItem = myDataModel.data([0])
  }
  

  indexOf search a value and returns it is row.

  UPD:

  In ArrayDataModel, there is also. value() function which takes a simple index.

  Data() is more generic function inherited from DataModel.

  So, it can be simplified to:

  var firstItem = myDataModel.value(0)
