Which of the function provides consecutive numbering except in the case of a tie?Question 8Answera.ROW_NUMBERb.NTILEc.RANKd.DENSE_RANK

The function that provides consecutive numbering except in the case of a tie is ROW_NUMBER.

Here's a step-by-step explanation:

1. ROW_NUMBER: This function provides a unique row number for each row, regardless of duplicates within a partition. So, even in the case of a tie, it will still provide a unique number.

2. NTILE: This function distributes the rows in an ordered partition into a specified number of groups. The groups are numbered, starting at one. For each row, NTILE returns the number of the group to which the row belongs.

3. RANK: This function provides a unique rank number for each distinct row within a partition but leaves gaps in the ranking for duplicate rows. So, in the case of a tie, it will not provide a unique number.

4. DENSE_RANK: This function provides a unique rank number for each distinct row within a partition but does not leave gaps in the ranking for duplicate rows. So, in the case of a tie, it will not provide a unique number.

So, the answer is a. ROW_NUMBER.

The function that provides consecutive numbering except in the case of a tie is ROW_NUMBER.

Here's a step-by-step explanation:

1. ROW_NUMBER: This function is used to assign a unique row number to each record in the result set. It does not consider the values in any particular column, and it does not renumber in case of a tie. It simply assigns a unique number to each row.

2. NTILE: This function is used to divide an ordered partition into a specified number of groups, or 'tiles', and assign a number to each row representing the group to which it belongs. It does not provide consecutive numbering.

3. RANK: This function assigns a unique rank to each distinct row within a partition of a result set, with the same rank for duplicate values. In case of a tie, it leaves a gap and does not provide consecutive numbering.

4. DENSE_RANK: This function assigns a unique rank to each distinct row within a partition of a result set, with the same rank for duplicate values. However, unlike RANK, it does not leave a gap in the rank sequence when there is a tie. It still does not provide consecutive numbering in case of a tie.

So, the answer is a. ROW_NUMBER.
