title: How do I insert a NULL long value?
body: <p>I have a database made up a single table with several fields, one of which is a phone number that is stored as a NUMERIC. Because the phone number is 10 digits, in my code I have captured the variable as a LONG.</p>
  
  <p>My question is, in the insert statement, how do I pass a NULL value? Is this possible at all? I can't assign a null value to the LONG variable, so I'm wondering how to go about doing this...</p>
