    Description

      Suppose a(x, y)

      split a into b if x==y, c otherwise;

      One will expect the union of b and c will be a. However, if x or y is null, the record won't appear in either b or c.

      To workaround this, I have to change to the following:
      split a into b if x is not null and y is not null and x==y, c otherwise;
