Posts: 10,222. Grill marks have been discussed many times over the years.

How to call Function ? You call a Function procedure by using the procedure name, followed by the argument list in parentheses, in an expression. You can omit the parentheses only if you are not supplying any arguments. However, your code is more readable if you always include the parentheses.
Requirements for Calling Functions in SQL. The function must be stored in the database. A function defined in a client-side PL/SQL environment cannot be called from within SQL; there would be no way for SQL to resolve the reference to the function. All of the functionâs parameters must use the IN mode.
