This is a fully version (in Integer)

select  Extract(year FROM cast('NOW' as date))*10000 +
        Extract(month FROM cast('NOW' as date))*100 +
        Extract(day  FROM cast('NOW' as date)) from rdb$database

This is a fully version (in VARCHAR)

select  CAST(Extract(year FROM cast('NOW' as date))*10000 +
        Extract(month FROM cast('NOW' as date))*100 +
        Extract(day  FROM cast('NOW' as date)) AS VARCHAR(8)) from rdb$database
