------------------------------------
Hi Chang,
I won't close this jira if you disagree. :-) We can definitely add an example
to the SPLIT doc, and you're welcome to submit a patch for that if you like to.
I will be happy to review/commit it.

> 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;
