Examine the description of the CUSTOMERS table:

Name                        Null?                      Type

-----------------------------------------------------------------------

CUST_ID                       NOT NULL       NUMBER

CUST_FIRST_NAME     NOT NULL       VARCHAR2 (20)

CUST_LAST_NAME       NOT NULL      VARCHAR2 (30)

CUST_INCOME_LEVEL                          VARCHAR2 (30)

CUST_CREDIT_LIMIT                             NUMBER

For customers whose income level has a value, you want to display the first name and due amount as 5% of their credit limit. Customers whose due amount is null should not be displayed.

Which query should be used?

      FROM customers

      WHERE cust_income_level != NULL

      AND cust_credit_level != NULL;

B) SELECT cust_first_name, cust_credit_limit * .05 AS due_amount

      FROM customers

      WHERE cust_income_level IS NOT NULL

      AND cust_credit_limit IS NOT NULL;

C) SELECT cust_first_name, cust_credit_limit * .05 AS due_amount

      FROM customers

      WHERE cust_income_level Is NOT NULL

      AND due_amount IS NOT NULL; .

D) SELECT cust_first_name, cust_credit_limit * .05 AS due_amount

      FROM customers

      WHERE cust_income_level != NULL

      AND due_amount != NULL;

E) SELECT cust_first_name, cust_credit_limit * .05 AS due_amount

      FROM customers

      WHERE cust_income_level <> NULL

      AND due_amount <> NULL;
