Result set not returning what is expected - sql

Question

I am working on a query and am getting results I don't expect. Here is the query:

Here is part of the result set:
For the results of the first user two of the OrganizationTeams column cells return NULL. I don't understand why this is, this user is assigned the org team of 3:
Why isn't it returning 3 for all cells of this user and how can I ensure it does?

Answer 1

Your OrganizationalTeam Column is joined in via DailyTaskHours > Task > ProductTeamUser > User. Each join can result in a NULL value so check each of these joins. Try running that Query with SELECT * and using a WHERE to return only one of those two rows.
