      public static IOQLTextGetRequest createOQLTextGetRequest()
      Create a new IOQLTextGetRequest. This class can be used to define a textual OQL retrieval query.
      Returns:
      an IOQLTextGetRequest

    • createOQLTextGetRequestFromDataSet

      public static IOQLTextGetRequest createOQLTextGetRequestFromDataSet(String dataSetQualifiedName)
      Instantiate IOQLTextGetRequest from given qualified DataSet name.

      Code examples

      Example OQL query without parameters 

       
  private String getOqlQueryFromDataSet(String dataSetName) {
      final IOQLTextGetRequest oqlTextGetRequest = Core.createOQLTextGetRequestFromDataSet(dataSetName);

      return oqlTextGetRequest.getQuery();
  }

  public Report generateReport() {
      String oqlQuery = getOqlQueryFromDataSet();
      final IDataTable dataTable = Core.retrieveOQLDataTable(context, oqlQuery);
      final List<? extends IDataRow> rows = dataTable.getRows();
      Report report = new Report();
      report.addRow(rows.get(0));

      return report;
  }
      The above example first defines a getOqlQueryFromDataSet method at the top, which returns a OQL query in string format. It takes a qualified dataSetName which means DataSet name along with its module name separated by '.' character. For example, if the name of the DataSet is ReportGeneratorDataSet and it belongs to a module named Reporting then the qualified DataSet name will be Reporting.ReportGeneratorDataSet.
      This method is then used in generateReport method which retrieves a database data table from the OQL query.

      Example OQL query along with its parameters 
       
 public Report generateReport(String dataSetName) {
     final IOQLTextGetRequest oqlTextGetRequest = Core.createOQLTextGetRequestFromDataSet(dataSetName);
     final IParameterMap newParameterMap = oqlTextGetRequest.createParameterMap();
     newParameterMap.put("ParGroupNumber", 4); // Set value of ParGroupNumber parameter to 4
     oqlTextGetRequest.setParameters(newParameterMap);
     final IDataTable dataTable = Core.retrieveOQLDataTable(context, oqlTextGetRequest);
     final List<? extends IDataRow> rows = dataTable.getRows();
     Report report = new Report();
     report.addRow(rows.get(0));

     return report;
 }
      The above example defines a similar generateReport method as shown in the previous example, however in this case the given DataSet has a OQL query which takes parameters. Let us consider that the given DataSet contains following OQL query with a parameter named ParGroupNumber - 
       
   FROM CRM.Customers As CustomerObj
   INNER JOIN CustomerObj/CRM.Orders_Customer/CRM.Orders As OrderObj
   WHERE CustomerObj/CRM.Customer_Group/CRM.Group/GroupNumber = $ParGroupNumber
   GROUP BY CustomerObj/Name
   SELECT CustomerObj/Name As Name, SUM(OrderObj/TotalAmount) As TotalAmount
      Using the DataSet name generateReport method first creates a oqlTextGetRequest. Next, in order to set the ParGroupNumber parameter a new IParameterMap is instantiated and the value of ParGroupNumber parameter is specified, which in the above example would be 4. Finally we provide this newParameterMap to the setParameters method of IOQLTextGetRequest. This modified request is then used to retrieve a data table from the database, which in turn is used to generate a report.
      Parameters:
      dataSetQualifiedName - the qualified name of the DataSet containing OQL
      Returns:
      an instance of IOQLTextGetRequest if DataSet with OQL is found by given name
      Throws:
      IllegalArgumentException - if given qualified name is null, has invalid format, found DataSet contains Java Action or DataSet is not found

    • createXPathQuery

      public static XPathQuery createXPathQuery(String xpathQuery)
      Creates an XPath query representation that can be built up in a fluent manner

      Can be used to create and execute XPath queries in a fluent manner. For example: 

       
 public getObjectsWithValue(IContext context, ICore core, int value) {
     List<IMendixObject> results = core.createXPathQuery("//Entity[attribute=$value]")
         .setVariable("value", 1)
         .setAmount(500)
         .setOffset(50)
         .setDepth(1)
         .execute(context);
     return results;
 }

      After the XPath query is built up, XPathQueryBase.execute(IContext) can be called to retrieve the results.

      Parameters:
      xpathQuery - the XPath query to execute. Variable can be denoted with '$', e.g. a valid query syntax could be '//Entity.Ref[field >= $limit)'.
      Returns:
      instance of XPathQuery that can be used to construct an XPath query
