If several orders from the same client have the same amount, how will the behavior of DENSE_RANK() change compared to RANK()? - DENSE_RANK() skips the next number, RANK() does not - DENSE_RANK() assigns the same rank to equal sums and does not skip the next number, RANK() skips - There is no difference - DENSE_RANK() outputs unique numbers, RANK() outputs the same

Correct answer:

• DENSE_RANK() assigns the same rank to equal sums and does not skip the next number, RANK() skips

Explanation:

• RANK() assigns the same rank to equal values but skips numbers for the next rank. For example, if two orders have a sum of 100 and occupy rank 1, the next rank will be 3.

• DENSE_RANK() also assigns the same rank to equal values but does not skip numbers. In the same example, the next rank will be 2.

Thus, with multiple orders having the same sum, DENSE_RANK() will produce consecutive ranks without gaps, while RANK() will have gaps.
