title: Biztalk Database Lookup functoid and Value Extractor no match
body: <p>I have an element in the source schema of a map that contains a code. I am using this as an input to a database lookup functoid. The output of the database lookup functoid is being passed as an input parameter to a value extractor functoid, which is outputting a column value. So far so good all as expected.</p>
  
  <p>My question is how do I handle no match? Would I get null out of the value extractor functoid and how could I default this to the original input code going into the database lookup functoid if no match was found?</p>
