Question
If both tables are pre-sorted on the join columns the optimizer chooses a HASH join, which is faster and uses considerably fewer resources.A.TrueB.False
Solution
B. False
If both tables are pre-sorted on the join columns, the optimizer is more likely to choose a MERGE join, not a HASH join. A HASH join is typically used when the join columns are not sorted because it doesn't rely on the order of the data. On the other hand, a MERGE join is efficient when the join columns are already sorted because it can simply merge the two tables together.
