Oracle Exam 1Z0-071 Topic 3 Question 21 Discussion

You execute these commands:

CREATE TABLE customers (customer_id INTEGER, customer_name VARCHAR2 (20) )

TNSERT INTO customers VALUES (1, 'Customer 1 ' ) ;

SAVEPOTNT post_insert;

INSERT INTO customers VALUES (2, 'Customer 2');

SELECT COUNT(*) FROM customers;

Which two, used independently, can replace so the query returns 1?
