User-defined functions combine the advantages of stored procedures with the capabilities of SQL predefined functions. They can accept parameters, perform specific calculations based on data retrieved by one or more SELECT statement, and return results directly to the calling SQL statement.
PL/SQL. PL/SQL syntax to create user-defined functions is not much different from that for stored procedures.

Any code after the RETURN statement in the function body will be ignored.
