Build a Simple VCL Application for Oracle Eloqua Data

How to build a simple VCL Application to view Oracle Eloqua data in RAD Studio using the CData FireDAC Components for Oracle Eloqua.

Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData FireDAC Components for Oracle Eloqua, you gain access to live Oracle Eloqua data within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to both retrieve and update Oracle Eloqua data. This article will walk through connecting to Oracle Eloqua and creating a simple VCL application with the Form Designer.

Creating a VCL Application for Oracle Eloqua Data

The following instructions show how to use the Form Designer to create a simple VCL Forms application that shows the basic FireDAC objects needed to connect to Oracle Eloqua from any application.

The following example populates a TDBGrid control.

  1. Create a new VCL Forms Application.
  2. Drop a TFDPhysEloquaDriverLink and TFDConnection object onto the form.
  3. Double-click the TFDConnection object. The FireDAC Connection Editor is displayed. Select "CData.Eloqua" in the DriverId menu and configure the connection properties.

    There are two authentication methods available for connecting to Eloqua: Login and OAuth. The Login method requires you to have the Company, User, and Password of the user.

    If you do not have access to the username and password or do not wish to require them, you can use OAuth authentication. OAuth is better suited for allowing other users to access their own data. Using login credentials is better suited for accessing your own data.

  4. Drop a TFDQuery object onto the form and set the properties below:

    • Connection - Set this property to the TFDConnection object, if this object is not already specified.
    • SQL - Click the button in the SQL property and enter a query.
    • Active - Set this property to true.
  5. Drop a TDataSource object onto the form and set the following property:

    • DataSet - In the menu for this property, select the name of the TFDQuery object.
  6. Drop a TDBGrid control onto the form and set the following property:

    • DataSource - Select the name of the TDataSource.
  7. Drop a TFDGUIxWaitCursor onto the form. This is required to avoid a run-time error.

You now have an executable application that displays the results of the SQL Query set in the TFDQuery object.
