2 Input and Output Parameters are permitted Only input parameters are permitted
3 Need not necessarily return a value A return value is necessary
4  A Function can be invoked by a Stored Procedure  A Stored Procedure cannot be invoked by a Function
5  SELECT,INSERT, UPDATE, DELETE cannot call a Stored Procedure  SELECT,INSERT, UPDATE, DELETE can call a Function
