See the Exhibit and Examine the structure of the CUSTOMERS table:

Using the CUSTOMERS table, you need to generate a report that shows an increase in the credit limit by 15% for all customers. Customers whose credit limit has not been entered should have the message "Not Available" displayed.

Which SQL statement would produce the required result?

  • A

    SELECT NVL(cust_credit_limit,'Not Available')*.15 "NEW CREDIT" FROM customers;

  • B

    SELECT NVL(cust_credit_limit*.15,'Not Available') "NEW CREDIT" FROM customers;

  • C

    SELECT TO_CHAR(NVL(cust_credit_limit*.15,'Not Available')) "NEW CREDIT" FROM customers;

  • D

    SELECT NVL(TO_CHAR(cust_credit_limit*.15),'Not Available') "NEW CREDIT" FROM customers;
