That is only true if you assume the examples are against the example employee database, and that is not actually the case. Both the [Firebird 3][1] and the Firebird 4 beta 1 release notes have used an `employee` table with columns `id`, `salary`, `department` for its window functions examples. That table is explicitly introduced in the Firebird 3 release notes (see under "Aggregate Functions Used as Window Functions"_) with _"Imagine a table EMPLOYEE with columns ID, NAME and SALARY, [..]."_ (note that it doesn't define `department`, though that does get used and `name` does not). Maybe that (corrected) definition needs to be repeated in the Firebird 4 release notes.

[Firebird-docs] Wrong example in FB 4.0 Beta release notes
Hi, I think we have a simple error in the release docs for FB 4.0 Beta 1: Section More Window Functions (Pages: 76-77) Ranking Functions: DENSE_RANK() | RANK() | PERCENT_RANK() | CUME_DIST() | NTILE() | ROW_NUMBER() Simple Example The following example illustrates the behaviour of ranking functions. SUM is included for comparison. SQL> select CON> id, CON> salary, CON> dense_rank() over (order by salary), CON> rank() over (order by salary), CON> percent_rank() over (order by salary), CON> cume_dist() over (order by salary), CON> ntile(3) over (order by salary), CON> row_number() over (order by salary), CON> sum(1) over (order by salary) CON> from employee CON> order by salary; Statement failed, SQLSTATE = 42S22 Dynamic SQL Error -SQL error code = -206 -Column unknown -ID -At line 2, column "id" has to be "emp_no". The same for the table. Please verify. I don't have an installation of FB 4.0.
