Create Company Table Page

On the client node, go to 'Desktop' | 'Outlines' | 'StandardOutline' | 'Child Pages'. Right click on the node to create a new TablePage [1]. As page layout, choose AbstractPageWithTable [2] to create a page representing tabular data. On the next step, enter Company as name for that page and choose to add this page to the StandardOutline [3]. By clicking Finish, the page is created and attached to the StandardOutline.

Create columns

On the CompanyTablePage node, go to 'Table' | 'Columns'. Right click on the node to create a new Column [4]. Please add the following three columns to that table:

CompanyNrColumn
Type: Long Column [5]
Name: Do not fill because column represents primary key and therefore is hidden
Class name: CompanyNrColumn [6]
NameColumn
Type: String Column
Name: Name
Class name: NameColumn
SymbolColumn
Type: String Column
Name: Symbol
Class name: SymbolColumn

To not display the CompanyNr column because of holding the primary key, go to that column in Scout SDK and uncheck Displayable in Scout Property View [7].

To have the columns equally distributed over the available space of the table page, go to the Table node and check Auto Resize Columns in Scout Property View [8].

Create service to load company data from database

Now we have to populate the table with company data. For that purpose, double click on the StandardOutlineService under 'Server' | 'Outline Services' to open the corresponding Java class. In there, create the operation getCompanyTableData to load company data from database. Also add the operation signature to the service interface IStandardOutlineService to be accessible from client side. To find the interface IStandardOutlineService, press Ctrl+Shift+T, type IStandardOutlineService and click 'Open'.

public class StandardOutlineService extends AbstractService implements IStandardOutlineService {
 
  @Override
  public Object[][] getCompanyTableData() throws ProcessingException {
    return SQL.select("" +
        "SELECT   COMPANY_NR, " +
        "         NAME, " +
        "         SYMBOL " +
        "FROM     COMPANY ");
  }
}

Load company data into CompanyTablePage

Now as the StandardOutlineService is ready to load company data from the database, go back to the CompanyTablePage to consume the service's data. On the Scout Property View, click on the operation Exec Load Table Data to populate the company table [9]. Implement the method as follows:

@Override
protected Object[][] execLoadTableData(SearchFilter filter) throws ProcessingException {
  return SERVICES.getService(IStandardOutlineService.class).getCompanyTableData();
}

Finally, if you launch the application, you should see something like this:
