# 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
|
|
```
