- I am stuck on a question. 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.Write a SELECT statement that returns all rows with salary, last name, street address and ZIP code (SALARY, LAST_NAME, STREET, ZIP_CODE) from the EMPLOYEE and ADDRESS tables, sorted by SALARY from largest to smallest. STREET and ZIP_CODE are in the ADDRESS table, while the other fields are in the EMPLOYEE table. The common key is EMPLOYEE_ID.Write a script that creates and calls a stored procedure named spInsertInstructor that inserts a row into the Instructors table. This stored procedure should accept one parameter for each of these columns: LastName, FirstName, Status, DepartmentChairman, AnnualSalary, and DepartmentID. This stored procedure should set the DateAdded column to the current date. If the value for the AnnualSalary column is a negative number, the stored procedure should raise an error that indicates that this column doesn’t accept negative numbers. Code at least two EXEC statements that test this procedure.
