Don't get the Point nor I see a question. Do you mean "where x2.roba is not null " with last line?

Solution 2

If you are using TSQL you could use IsNull

SQL

where isnull(x2.roba, 0) = 0

Solution 1

Not sure if I understand the question correctly but do you mean hat the comparison should use 0 if x2.roba is null? In that case consider

SQL

where coalesce(x2.roba, 0) = 0
