You have been instructed to add a new customer to the CUSTOMERS table. Because the new customer has not had any orders before, you should not add an amount to the total pay column.

The CUSTOMERS table contains these columns:

CUST_ID NUMBER(10)

CUST_NAME VARCHAR2(30)

CUST_PHONE NUMBER(10)

TOTAL_PAY NUMBER(6,2)
