Sorry to trouble you again. Why do you think if I replace 0 (in your code above) with space(len()), my SQL selects NULLs?

Here is how my code looks like:

SELECT ISNULL(x, space(len(x)) FROM table_x GROUP BY ISNULL(x, space(len(x));

Do you see what I am missing?

UPDATE. I replaced SPACE(...) with '' (empty string) and all works fine.
