Which statement will successfully assign $75,000,000 to the V_MAX_TEAM_SALARY variable
from within a stand-alone procedure?

• A.  This variable cannot be assigned a value from outside the package.
• B.  BB_PACK.V_MAX_TEAM_SALARY := 75000000;

Examine this code:
CREATE OR REPLACE FUNCTION gen_email_name
(p_first_name VARCHAR2, p_last_name VARCHAR2, p_id NUMBER)
RETURN VARCHAR2
IS
v_email_name VARCHAR2(19=;
BEGIN
v_email_name := SUBSTR(p_first_name, 1, 1) ||
SUBSTR(p_last_name, 1, 7) ||
'@Oracle.com';
UPDATE employees
SET email = v_email_name
WHERE employee_id = p_id;
RETURN v_email_name;
END;
Which statement removes the function?

• A.  TRUNCATE gen_email_name;
• B.  DELETE gen_email_name;
• C.  DROP FUNCTION gen_email_name;
• D.  ALTER FUNCTION gen_email_name REMOVE;
• E.  REMOVE gen_email_name;

Examine this code:
CREATE OR REPLACE FUNCTION gen_email_name
(p_first_name VARCHAR2, p_last_name VARCHAR2, p_id NUMBER)
RETURN VARCHAR2
is
v_email_name VARCHAR2(19);
BEGIN
v_email_home := SUBSTR(p_first_name, 1, 1) ||
SUBSTR(p_last_name, 1, 7) ||
'@Oracle.com';
UPDATE employees
SET email = v_email_name
WHERE employee_id = p_id;
RETURN v_email_name;
END;
You run this SELECT statement:
SELECT first_name, last_name
gen_email_name(first_name, last_name, 108) EMAIL
FROM employees;
What occurs?

• A.  The statement fails because the functions does not contain code to end the transaction.
• B.  The SQL statement executes successfully, because UPDATE and DELETE statements are ignoring in stored functions called from SQL expressions.
• C.  The statement fails because functions called from SQL expressions cannot perform DML.
• D.  Employee 108 has his email name updated based on the return result of the function.
• E.  The SQL statement executes successfully and control is passed to the calling environment.
