FILTER has been implemented in Firebird 4. See "FILTER Clause for Aggregate Functions" in the Firebird 4 beta 1 release notes, or http://tracker.firebirdsql.org/browse/CORE-5768 Note though that the order you mention is not right, it right order would be count(other_col) filter (where other_col > soime_val) over(), or filter-clause before window-clause(that is also the order in PostgreSQL).
