How to connect to MySQL with NBi?

I often receive questions such as “Does NBi work with MySQL/PostgreSQL?” or “Is it possible to use another database than SQL Server?”. The answer is definitively: YES! NBi is working with all databases supporting OleDB or ODBC connections.

Today, I’ll specifically answer¬†the question about MySQL, tomorrow I’ll edit another blog post about PostgreSQL. For MySQL, I’ll connect from NBi by using an ODBC connector. Indeed, MySQL has no support for an OleDB connector. To be 100% transparent, some old versions of OleDB connectors exist but it doesn’t sound to have any active development on these projects.

Start by downloading the latest version of the¬†ODBC driver for MySQL from the MySQL website. Then install it. You can check that the ODBC driver has been correctly installed in the “Program and Features” panel:


Another great way to check that the ODBC drivers are installed is to user PowerShell and the cmdlet


This method returns the following list where you should find something related to MySQL.


Do you need the 32-bits(x86) or 64-bits(x64) drivers? It depends of the application using the ODBC driver … both need to match. When using the nunit-console or the GUI of NUnit, you’ll need the 64-bits version. But if you’re running your tests from Visual Studio then you’ll need the 32-bits version. You can install both on the same computer but it’s apparently recommended to install first the 64-bits version and then the 32-bits. Haven’t checked this personally.

When the connector is successfully installed, edit your test-suite and define the connection string to your MySQL server as:

      "Driver={MySQL ODBC 5.3 UNICODE Driver};
     select count(*) from adventureworks.address

We could also use this connection string in our settings (defaults or references) or in our config file.

Now, you can use your MySQL instance exactly the same way you’d use a SQL Server instance.
