Dynamics NAV Icon Dynamics NAV ODBC Driver

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

Access Dynamics NAV like you would a database - read, write, and update Items, Sales Orders, Purchase Orders, etc. through a standard ODBC Driver interface.

Build a Simple VCL Application for Dynamics NAV Data


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

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

Create a Connection to Dynamics NAV 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.

Before you can connect, OData Services will need to be enabled on the server. Once OData Services are enabled, you will be able to query any Services that are published on the server.

The User and Password properties, under the Authentication section, must be set to valid Dynamics NAV user credentials. In addition, you will need to specify a URL to a valid Dynamics NAV server organization root and a ServerInstance. If there is not a Service Default Company for the server, you will need to set the Company as well.

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

Create VCL Applications with Connectivity to Dynamics NAV Data

Follow the procedure below to start executing queries to Dynamics NAV 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 Dynamics NAV 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, Prices_Including_VAT FROM Customer
    • 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.
