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

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

Creating a VCL Application for Oracle Sales 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 Sales from any application.

The following example populates a TDBGrid control.

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

    Oracle Sales uses Basic authentication over SSL; after setting the following connection properties, you are ready to connect:

    • Username: Set this to the user name that you use to log into your Oracle Cloud service.
    • Password: Set this to your password.
    • HostURL: Set this to the Web address (URL) of your Oracle Cloud service.

  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.
