Question

I am trying to build a trigger that would not allow users to give a salary higher than 10,000 to employees but if the employee is a manager, I don’t want the user to be able to give less than 15000 of a salary.

What I reached so far is the following

create or replace trigger sal_check 
before update or insert on emp
for each row
begin 
if :new.sal > 10000
then
update emp set sal = 10000;
end if;
end;

Now can I please take a hint of how to do a check whether the employee is a manager or not?

Note : I am using Oracle, and this is running on Scott schema, the one that actually comes with Oracle by default.

I think you should create a table (not temporary) with all the managers.

Afterwords, it would be quite easy to detect if a employee is a manager or not and by making a simple select on that table you could see what should be the salary.

To determine what employees should be on the table, it would be the ones in the mgr column.
