title: ASP Classic check for database NULL value in Recordset
body: <p>I'm getting an ADODB Recordset and I need to check the value of a nullable column in ASP Classic.  How can I tell whether it's null?  AFAIK IsDBNull doesn't exist in ASP Classic, and all the Null testers ask whether the object is null, not its value.</p>
  
  <p>E.g., I have Recordset <code>RS</code> that contains a column <code>RS("myCol")</code>.  In the database, myCol is a nullable bit, so values can be <code>{0, 1, NULL}</code>.</p>
  
  <p>How can I test <code>RS("myCol") = NULL</code>?  It appears that if I literally run that comparison it will only tell me whether the object RS("myCol") is Null, not whether the value of the field requested is "database" null.</p>
