C is definitely not right, it orders by Order_No instead of Amount.

Wait, can you really use %02 for dates? Seems off.

Totally agree with D, it’s the best choice!

I think A is wrong because of the LIKE syntax.

Option D looks correct, using %02 for the year.

I’m a bit confused about the ORDER BY clause; I thought we needed to sort by Amount, but I see some options using Order_No instead.

I practiced a similar question where we had to filter by year, and I feel like using %02 might be the right approach for matching the year.

I think option D looks familiar; it seems to match the pattern for the year, but I can't recall if the wildcard should be at the start or end.

I remember we discussed using the LIKE operator for date filtering, but I'm not sure if the wildcard placement is correct for 2002.

I feel pretty good about this question. The instructions are clear, and option D seems to hit all the requirements - selecting all columns, filtering for 2002 order dates, and ordering by amount. I'm going to go with that one.

Huh, I'm not sure about this one. The wording is a bit tricky, and I'm not totally confident in my SQL skills. I'm leaning towards option D, but I'll have to double-check my work before submitting.

Okay, I think I've got this. The key is to use the LIKE operator with the '_02' pattern to match all order dates in 2002, and then order the results by the Amount column in ascending order. Option A looks like the best choice here.

I'm a bit confused by the use of the LIKE operator here. Should we be using the wildcard character to match the year, or is there a better way to filter for just 2002 order dates?

Hmm, this looks like a pretty straightforward SQL query. I think I'll go with option D - that seems to match the requirements of returning all complete tuples for order dates in 2002, arranged by amount from lowest to highest.

Haha, I can't believe they're still using the ancient Orders relation in these exams. I bet the real world has moved on to something more exciting by now!

Hmm, I'm not sure about that. Shouldn't we be using the BETWEEN clause to select the date range instead of LIKE? I hope I don't mess this up on the exam.

User 1: I think you're right, we should use the BETWEEN clause for date ranges.

I agree, D is the right choice. The LIKE operator with the wildcard '%' matches any 2-digit year that ends in '02'.

The correct answer is D. It selects all tuples from the Orders relation where the Order_Date is in 2002, and arranges them by Amount in ascending order.

Yes, D selects all tuples from Orders in 2002 and arranges by Amount.

But A specifies ordering by Amount, which is what the question asks for.
