View the Exhibit and examine the data in EMPLOYEES and DEPARTMENTS tables. In the
EMPLOYEES table EMPLOYEE_ID is the PRIMARY KEY and DEPARTMENT_ID is the
FOREIGN KEY. In the DEPARTMENTS table DEPARTMENT_ID is the PRIMARY KEY.
Evaluate the following UPDATE statement: UPDATE employees a SET department_jd =
(SELECT department_id FROM departments WHERE location_id = ‘2100’), (salary,
commission_pct) = (SELECT 1.1*AVG(salary), 1.5*AVG(commission_pct) FROM
employees b WHERE a. department_jd = b. department_id) WHERE first_name||
‘||last_name = ‘Amit Banda’; What would be the outcome of the above statement?
A.
It would not execute successfully because multiple columns (SALARY
,COMMISSION_PCT)cannot be used in an UPDATE statement.
B.
It would execute successfully and update the relevant data.
C.
It would not execute successfully because there is no LOCATION_ID 2100 in the
DEPARTMENTS table.
D.
It would not execute successfully because the condition specified with the concatenation
operator is not valid.
Please update Exibit!! And update “|| ‘ ‘ ||” in the concatenation operator.
