title: Quick ways to test OLE DB Connection String
body: <p>For debugging purpose I'd like to know ways to test OLE DB connection string quickly.</p>
  
  <p>I've found <a href="http://www.digitalcoding.com/free-software/database/Database-Connection-String-Tester.html" rel="noreferrer">this free software</a>, it works on my machine, tested successfully.</p>
  
  <p>Is there a even quicker way to do so, maybe from command line on Windows? Because most of the time, it is the client rather than me that would do this task, so I prefer a "zero-installation" approach that would impact their system the least.</p>
