A stored function can be called as part of expression in any PL/SQL statement. One simplest way to call a stored function is to a dummy SELECT statement as shown in the following tutorial script using SQL*Plus:

SQL> CREATE OR REPLACE FUNCTION GET_SITE
  2    RETURN VARCHAR2 AS
  3  BEGIN
  4    RETURN 'FYICentere.com';
  5  END;
  6  /
Function created.

SQL> SELECT get_site() FROM dual;

GET_SITE()
---------------------------------
FYICentere.com

DUAL is not a real table or view. It is commonly used to with SELECT statement to evaluate expressions.
