View the Exhibit exhibit1 to examine the series of SQL commands. View the Exhibit exhibit2
to examine the plans available in the SQL plan baseline. The baseline in the first row of the
Exhibit is created when OPTIMIZER_MODE was set to FIRST_ROWS. Which statement is
true if the SQL query in exhibit1 is executed again when the value of OPTIMIZER_MODE is
set to FIRST_ROWS?
A.
The optimizer uses the plan in the first row of the exhibit2 because it is the latest
generated plan.
B.
The optimizer uses the plan in the first row of the exhibit2 because OPTIMIZER_MODE
was set to FIRST_ROW during its creation.
C.
The optimizer uses the plan in the second row of the exhibit2 because it is an accepted
plan.
D.
The optimizer uses a new plan because none of the plans in the exhibit2 are fixed plans.
