title: Convert SQL dateTime return 0 or emptyString
body: <p>I've tried some of the stackOverflow solution but still I get '1/1/1900' </p>
  
  <p>in my actual database the postDate has a:</p>
  
  <pre><code>------------
  |postedDate|
  ------------
    &lt;NULL&gt;
  </code></pre>
  
  <p>I've to create a query that looks like this, thinking that this would return a '0' but it doesn't, still I would return a '1/1/1900' value to me.</p>
  
  <pre><code>ISNULL(postedDate, CASE WHEN postedDate = '1/1/1900' THEN 0 ELSE postedDate END)
  
  ------------
  |postedDate|
  ------------
   1/1/19000
  </code></pre>
  
  <p>I need a result that somehow looks like this:</p>
  
  <pre><code>------------
  |postedDate|
  ------------
       0
  </code></pre>
  
  <p>or something like this:</p>
  
  <pre><code>------------
  |postedDate|
  ------------
      N/A
  </code></pre>
