Function Expressions

You can use any built-in SQL function or user-defined function as an expression. Some valid built-in function expressions are:

LENGTH('BLAKE') 
ROUND(1234.567*43) 
SYSDATE 

See Also:

Some valid user-defined function expressions are:

circle_area(radius)
payroll.tax_rate(empno)

In a user-defined function being used as an expression, positional, named, and mixed notation are supported. For example, all of the following notations are correct:

CALL my_function(arg1 => 3, arg2 => 4) ...
CALL my_function(3, 4) ...

CALL my_function(3, arg2 => 4) ...
