Functions


A function is a named, specialized operation performed on zero or more input values, that returns a single value when executed successfully. A function can appear anywhere a value expression is permitted. The function is invoked by its name, followed by the input argument(s) (if any) in parentheses.

There are several categories of functions: Aggregate, OLAP, Cast, String, Math, and Date/Time.
