Oracle HCM Cloud Icon Oracle HCM Cloud ODBC Driver

The Oracle HCM Cloud ODBC Driver is a powerful tool that allows you to connect with live data from Oracle HCM Cloud, directly from any applications that support ODBC connectivity.

Access Oracle HCM Cloud data like you would a database - read, write, and update Oracle HCM Cloud 0, etc. through a standard ODBC Driver interface.

Build a Simple VCL Application for Oracle HCM Cloud Data


How to build a simple VCL Application to view Oracle HCM Cloud data in RAD Studio using the CData ODBC Driver for Oracle HCM Cloud.

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

Create a Connection to Oracle HCM Cloud 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.

Using Basic Authentication

You must set the following to authenticate to Oracle HCM Cloud:

  • Url: The Url of your account.
  • User: The user of your account.
  • Password: The password of your account.

You can then follow the steps below to use the Data Explorer to create a FireDAC connection to Oracle HCM Cloud data.

  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 Oracle HCM Cloud.

Create VCL Applications with Connectivity to Oracle HCM Cloud Data

Follow the procedure below to start executing queries to Oracle HCM Cloud 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 Oracle HCM Cloud data.
    • 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 SiteId, SiteName FROM RecruitingCESites WHERE Language = 'English'
    • 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.

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