DataBind Controls to SAP SuccessFactors Data in C++Builder


DataBind to SAP SuccessFactors data in C++Builder with standard components and controls.

The CData ODBC driver for SAP SuccessFactors makes it easy to integrate connectivity to live SAP SuccessFactors data with standard data access components in C++Builder. This article shows how to create a simple visual component library (VCL) application in C++Builder that connects to SAP SuccessFactors data, executes queries, and displays the results in a grid. An additional section shows how to use FireDAC components to execute commands from code.

Create a Connection to SAP SuccessFactors Data

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

You can authenticate to SAP Success Factors using Basic authentication or OAuth with SAML assertion.

Basic Authentication

You must provide values for the following properties to successfully authenticate to SAP Success Factors. Note that the provider will reuse the session opened by SAP Success Factors using cookies. Which means that your credentials will be used only on the first request to open the session. After that, cookies returned from SAP Success Factors will be used for authentication.

  • Url: set this to the URL of the server hosting Success Factors. Some of the servers are listed in the SAP support documentation (external link).
  • User: set this to the username of your account.
  • Password: set this to the password of your account.
  • CompanyId: set this to the unique identifier of your company.

OAuth Authentication

You must provide values for the following properties, which will be used to get the access token.

  • Url: set this to the URL of the server hosting Success Factors. Some of the servers are listed in the SAP support documentation (external link).
  • User: set this to the username of your account.
  • CompanyId: set this to the unique identifier of your company.
  • OAuthClientId: set this to the API Key that was generated in API Center.
  • OAuthClientSecret: the X.509 private key used to sign SAML assertion. The private key can be found in the certificate you downloaded in Registering your OAuth Client Application.
  • InitiateOAuth: set this to GETANDREFRESH.

You can then follow the steps below to use the Data Explorer to create a FireDAC connection to SAP SuccessFactors.

  1. In a new VCL Forms application, expand the FireDAC node in the Data Explorer.
  2. Right-click the ODBC Data Source node in the Data Explorer.
  3. Click Add New Connection.
  4. Enter a name for the connection.
  5. In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for SAP SuccessFactors.

Create VCL Applications with Connectivity to SAP SuccessFactors Data

Follow the procedure below to start querying SAP SuccessFactors data from a simple VCL application that displays the results of a query in a grid.

  1. Drop a TFDConnection component onto the form and set the following properties:

    • ConnectionDefName: Select the FireDAC connection to SAP SuccessFactors.
    • Connected: Select True from the menu and, in the dialog that appears, enter your credentials.

  2. Drop a TFDQuery component onto the form and set the properties below:

    • Connection: Set this property to the TFDConnection component, if this component is not already specified.

    • SQL: Click the button in the SQL property and enter a query. For example:

      SELECT address1, zipCode FROM ExtAddressInfo WHERE city = 'Springfield'
    • Active: Set this property to true.

  3. Drop a TDataSource component onto the form and set the following property:

    • DataSet: In the menu for this property, select the name of the TFDQuery component.

  4. Drop a TDBGrid control onto the form and set the following property:

    • DataSource: Select the name of the TDataSource.
  5. Drop a TFDGUIxWaitCursor onto the form — this is required to avoid a run-time error.

Execute Commands to SAP SuccessFactors with FireDAC Components

You can use the TFDConnection and TFQuery components to execute queries to SAP SuccessFactors data. This section provides SAP SuccessFactors-specific examples of executing queries with the TFQuery component.

Connect to SAP SuccessFactors Data

To connect to the data source, set the Connected property of the TFDConnection component to true. You can set the same properties from code:

FDConnection1->ConnectionDefName = "CData SAP SuccessFactors ODBC Source"; FDConnection1->Connected = true;

To connect the TFDQuery component to SAP SuccessFactors data, set the Connection property of the component. When a TFDQuery component is added at design time, its Connection property is automatically set to point to a TFDConnection on the form, as in the application above.

Create Parameterized Queries

To create a parameterized query, use the following syntax below:

FDQuery1->SQL->Text = "select * from ExtAddressInfo where city = :city"; FDQuery1->ParamByName("city")->AsString = "Springfield"; FDQuery1->Open();

The example above binds a string-type input parameter by name and then opens the dataset that results.

Prepare the Statement

Preparing statements is costly in system resources and time. The connection must be active and open while a statement is prepared. By default, FireDAC prepares the query to avoid recompiling the same query over and over. To disable statement preparation, set ResourceOptions.DirectExecute to True; for example, when you need to execute a query only once.

Execute a Query

To execute a query that returns a result set, such as a select query, use the Open method. The Open method executes the query, returns the result set, and opens it. The Open method will return an error if the query does not produce a result set.

FDQuery1->SQL->Text = "select * from ExtAddressInfo where city = :city"; FDQuery1->ParamByName("city")->AsString = "Springfield"; FDQuery1->Open();

To execute a query that does not return a result set, use the ExecSQL method. The ExecSQL method will return an error if the query returns a result set. To retrieve the count of affected rows use the TFD.RowsAffected property.

FDQuery1->SQL->Text = "delete from ExtAddressInfo where Id = :Id"; FDQuery1->Params->Items[0]->AsString = "x12345"; FDQuery1->ExecSQL(); AnsiString i = FDQuery1->RowsAffected; ShowMessage("Rows affected: " + i);
