Aggregate Functions

ANY_VALUE (Firebird 6.0)

ANY_VALUE is a non-deterministic aggregate function that returns its expression for an arbitrary record from the grouped rows.

NULLs are ignored. It's returned only in the case of none evaluated records having a non-null value.

Syntax:

<any value> ::= ANY_VALUE(<expression>)

Example:

select department,
       any_value(employee) employee
    from employee_department
    group by department
