Which is the join in which all the rows from the right table appear in the output irrespective of the content of the other table?

This question asks about a type of join in SQL. A join combines data from two tables based on a common column. Let's understand the different join types:

Option A: CARTESIAN JOIN
This type of join creates a new table containing all possible combinations of rows from both tables. It's not commonly used, as it can result in a huge dataset.

Option B: CROSS JOIN
This join is similar to a CARTESIAN JOIN. It also creates a new table with all possible combinations of rows from both tables. This is the same as a CARTESIAN JOIN.

Option C: INNER JOIN
This join returns rows only when there's a match in the common column of both tables. It only keeps rows with matching values.

Option D: RIGHT JOIN
This join returns all the rows from the table on the right side of the JOIN clause. It also includes rows from the left table where there's a match in the common column. If no match exists, it shows NULL values for columns from the left table.

Therefore, the answer is Option D: RIGHT JOIN as it guarantees that all rows from the right table will appear in the output, even if there's no matching value in the left table.
