Dear angelll , thanks for you answer , it seems you answer is correct , but I couldn't undrestand the reason of "where b.b1 is null" . I guess it shouldn't work somewhere , am I right ?

just try to run the query without that part, and add b.b1 in the select list, and see the values of b.b1 in regards t the rows you want to have returned...
