The Office 365 ODBC Driver is a powerful tool that allows you to connect with live data from Office 365, directly from any applications that support ODBC connectivity.

Access Office 365 data like you would a database - read, write, and update Outlook Mail, Contact, Calendar, Files, etc. through a standard ODBC Driver interface.



How to build a simple VCL Application to view Office 365 data in RAD Studio using the CData ODBC Driver for Office 365.

Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for Office 365, you gain access to live Office 365 data within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to retrieve and update Office 365 data. This article will walk through connecting to Office 365 and creating a simple VCL application with the Form Designer.

Create a Connection to Office 365 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.

Office 365 uses the OAuth authentication standard. To authenticate requests, you will need to obtain the OAuthClientId, OAuthClientSecret, and OAuthCallbackURL by registering an app with Office 365. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

You can then follow the steps below to use the Data Explorer to create a FireDAC connection to Office 365 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 Office 365.

Create VCL Applications with Connectivity to Office 365 Data

Follow the procedure below to start executing queries to Office 365 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 Office 365 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 Name, Size FROM Files ORDER BY Size
    • 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.
