Microsoft DP-600 Exam - Topic 1 Question 9 Discussion

Actual exam question for Microsoft's DP-600 exam
Question #: 9
Topic #: 1
[All DP-600 Questions]

You have a Fabric tenant that contains a lakehouse. You plan to use a visual query to merge two tables.

You need to ensure that the query returns all the rows that are present in both tables. Which type of join should you use?

Show Suggested Answer Hide Answer
Suggested Answer: C

When you need to return all rows that are present in both tables, you use a full outer join. This type of join combines the results of both left and right outer joins and returns all rows from both tables, with matching rows from both sides where available. If there is no match, the result is NULL on the side of the join where there is no match.

I thought left outer could be used for this scenario.

I keep mixing up the types of joins. I thought left outer joins included all rows from one table, but I can't recall if that's what we need here.

I practiced a similar question where we had to merge tables, and I think the inner join was the right choice for that one too.

I'm leaning towards a full outer join as well. That seems like the safest way to ensure we get all the rows from both tables.

Based on the question, I think a left outer join would be the best option. That way, we'd get all the rows from the first table and any matching rows from the second table.

Okay, I think I've got this. If node protection can't be provided, the PLR should attempt to provide link protection instead. Option A looks like the right answer here.

I'll focus on the formula: remaining years × (annual income - annual expenses) ÷ interest rate. Don't panic, just methodical calculation.

Accident Report sounds like the most obvious choice here. That's the transaction that would contain the details about an accident, right? I'll go with that one.

That's true, but in this case, we want all rows from both tables, so a full outer join is more appropriate.

Haha, you guys are really overthinking this. Why not just use an inner join? It will only return the rows that are present in both tables, which is what the question is asking for.

Good point, Clarinda. A left outer join will return all the rows from the left table and the matching rows from the right table. This could be useful if we want to prioritize one table over the other.

This is a tricky question. We need to make sure we understand the requirements properly. The question states that we need to return all the rows that are present in both tables, so a full outer join seems like the best option.
