Examine the following SQL statement: Examine the exhibit to view the execution plan. Which statement is true about the execution plan?

The correct answer is E. The rows with the ID 3 and 4 are executed simultaneously. Note the other_tag parallel in the execution plan. Within the Oracle plan_table, we see that Oracle keeps the parallelism in a column called other_tag. The other_tag column will tell you the type of parallel operation that is being performed within your query. For parallel…

Explanation

Note the other_tag parallel in the execution plan. Within the Oracle plan_table, we see that Oracle keeps the parallelism in a column called other_tag. The other_tag column will tell you the type of parallel operation that is being performed within your query. For parallel queries, it is important to display the contents of the other_tag in the execution.
