I practiced a question like this last week, and I think the answer was option A, but I might be mixing it up with another example.

I think the query should return all matching records, but I’m a bit confused about how NULL values are handled in the join.

This question feels similar to one we did in class about combining tables. I think it might be option C, but I can't recall the exact details.

I remember practicing joins, but I'm not sure if it's an inner join or outer join in this case.

This seems straightforward, but I want to double-check my work. I'll walk through the join logic and compare the potential output options to make sure I have the right understanding.

I've got a strategy for this. I'll start by sketching out the expected result set based on the table contents and the join condition. That should help me identify the right answer.

Ugh, I'm not too familiar with the Create Change Request Type customizing in SAP. I'll have to think this through carefully.
