Invoke the EMP_PKG.ADD_EMPLOYEE procedure, using department ID 15 for employee Jane Harris with the e-mail ID JAHARRIS. Because department ID 15 does not exist, you should get an error message as specified in the exception handler of your procedure. c. Invoke the ADD_EMPLOYEE package procedure by using department ID 80 for employee David Smith with the e-mail ID DASMITH
