Hello,
You can create SQL connection and use Datareader to read from SQL.Firs create a connection string and put this string in web application web.config file of your sharepoint site.
Now use below code to call your connectionstring in your webpart.
SqlConnection con = new SqlConnection(System.Configuration.ConfigurationManager.AppSettings["ConnectionString"]);
Here is link to read the data from SQL:

Here is one MSDN link to read SP list data:
