title: SQL statement to check for connectivity?
body: <p>I'm looking for a dummy SQL statement that will work from a C# SQL connection to check for connectivity.</p>
  
  <p>Basically I need to send a request to the database, I don't care what it returns I just want it to be successful if the database is still there and throw an exception if the database isn't.</p>
  
  <p>The scenario I'm testing for is a loss of connectivity to the database, where the SQLConnections State property seems to still be "Open" but there is no connectivity.</p>
