title: Return a Single Map in IBATIS
body: <p>I have a SqlMap query that returns 2 columns, an ID and a string.  I know how to return a list of maps where the ID is the key and the string is the value.  There is one list item for each row returned.  </p>
  
  <p>How can I return 1 map with the IDs as keys and strings as values?</p>
