Using the CData ODBC Driver for Dynamics NAV in PyCharm

Connect to Dynamics NAV as an ODBC data source in PyCharm using the CData ODBC Driver for Dynamics NAV.

The CData ODBC Drivers can be used in any environment that supports loading an ODBC Driver. In this tutorial we will explore using the CData ODBC Driver for Dynamics NAV from within PyCharm. Included are steps for adding the CData ODBC Driver as a data source, as well as basic PyCharm code to query the data source and display results.

To begin, this tutorial will assume that you have already installed the CData ODBC Driver for Dynamics NAV as well as PyCharm.

Add Pyodbc to the Project

Follow the steps below to add the pyodbc module to your project.

  1. Click File -> Settings to open the project settings window.
  2. Click Project Interpreter from the Project: YourProjectName menu.
  3. To add pyodbc, click the + button and enter pyodbc.
  4. Click Install Package to install pyodbc.

Connect to Dynamics NAV

You can now connect with an ODBC connection string or a DSN. See the Getting Started section in the CData driver documentation for a guide to creating a DSN on your OS.

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.

Below is the syntax for a DSN:

[CData DynamicsNAV Source] Driver = CData ODBC Driver for Dynamics NAV Description = My Description http://myserver:7048 User = myserver\Administrator Password = admin ServerInstance = DYNAMICSNAV71

Execute SQL to Dynamics NAV

Instantiate a Cursor and use the execute method of the Cursor class to execute any SQL statement.

import pyodbc cnxn = pyodbc.connect('DRIVER={CData ODBC Driver for DynamicsNAV};http://myserver:7048;User = myserver\Administrator;Password = admin;ServerInstance = DYNAMICSNAV71;') cursor = cnxn.cursor() cursor.execute("SELECT Name, Prices_Including_VAT FROM Customer WHERE Name = 'Bob'") rows = cursor.fetchall() for row in rows: print(row.Name, row.Prices_Including_VAT)

After connecting to Dynamics NAV in PyCharm using the CData ODBC Driver, you will be able to build Python apps with access to Dynamics NAV data as if it were a standard database. If you have any questions, comments, or feedback regarding this tutorial, please contact us at support@cdata.com.
