Please assist with writing this code: Create a trigger for the EMPLOYEES table that will set the commission amount to .4 whenever the department_id is 80. Test your trigger COMPLETELY for every event it is defined. (Sometimes, UPDATE statements must have UPDATE tablename on a separate line by itself to keep APEX from hanging). This should work both for new rows and existing rows that are updated. Scenerio: All employees who are in the sales department (80) will have their commission always set to .4. This trigger is to enforce this business rule automatically.
