@SakiTakamachi do you know what the FireBird issue is? It seems it doesn't support the SQL query :/

I’m not feeling well, so I’ll check this issue once I’ve recovered!

Firebird requires a FROM clause IIRC. So add FROM RDB$DATABASE. (be careful about the dollar tho)
EDIT: well, adding that from RDB$DATABASE won't work for the other databases ofc :P Also I'm not sure you can end with a semicolon.
