       Requests a specific 1-indexed row from the result set. Passing this

  &reftitle.returnvalues;
  <para>
   Returns an object representing a single row in the result set. The
   properties of the object map to the names of the columns in the result set.
  </para>
  <para>
   The IBM DB2, Cloudscape, and Apache Derby database servers typically fold
   column names to upper-case, so the object properties will reflect that case. 
  </para>
  <para>
   If your SELECT statement calls a scalar function to modify the value
   of a column, the database servers return the column number as the name of
   the column in the result set. If you prefer a more descriptive column name
   and object property, you can use the AS clause to assign a name to the
   column in the result set.
  </para>
  <para>
   Returns &false; if no row was retrieved.

    <para>
     The following example issues a SELECT statement with a scalar function,
     RTRIM, that removes whitespace from the end of the column. Rather than
     creating an object with the properties "BREED" and "2", we use the AS
     clause in the SELECT statement to assign the name "name" to the modified
     column. The database server folds the column names to upper-case,
     resulting in an object with the properties "BREED" and "NAME".
    </para>
