Difference between Functions and Stored Procedure:
1. Function always return value, but procedure may return
value or not.
2. Function return only one value, but procedure return one
value or more than one value.
3. In Function, we can insert a value through parameter
passing like IN. but in procedure, we can insert value using
IN or get a value using OUT or both insert and get value
through single parameter using INOUT.
4. Function are used to perform computation, but procedures
are used to perform business logic.
5. Function are needed to compile when they are called, but
procedures are compiled only one time, so procedures are no
need to compile again. Because the procedure are in pre
compiled format.
6. Function can be called with SQL query but procedure can
not be used with SQl query.
