PL / SQL，如何使触发器打印出特定的列行？

Question

In my particular case I need to print out the 'emp_id' and 'salary' of every employee that has a salary above 100'000. It just needs to check and then print them out.

CREAT OR REPLACE TRIGGER idNumber
BEFORE 
CREATE OR REPLACE TRIGGER salary_trigger
AFTER INSERT or UPDATE OF salary, ON Employee
for each row
WHEN (salary > 100000)
DECLARE 
BEGIN 
if salary > 100000
THEN 
DBMS_OUT.PUT_LINE(salary, emp_id);
END;
/

Answer 1

Why a trigger? Surely just

select emp_id, salary
from Employee
where salary > 100000;

will do?
