       case a.mon$state 
          when 1 then 'active'
          when 0 then 'idle'
       end as State, 
       a.mon$attachment_name as Database_Name, 
       a.mon$user as User_Name, 
       a.mon$role as Role_Name, 
       a.mon$remote_protocol as Remote_Protocol, 
       a.mon$remote_address as  Remote_Address, 
       a.mon$remote_pid as Remote_PID, 
       cs.rdb$character_set_name as Connection_Character_Set, 
       a.mon$timestamp as Established_At,
       case a.mon$garbage_collection 
          when 1 then 'allowed'
          when 0 then 'not allowed'
       end as Garbage_Collection, 
       a.mon$remote_process as Remote_Process, 
       a.mon$stat_id as Statistics_ID
    FROM
       mon$attachments a, rdb$character_sets cs
    where 
       (a.mon$character_set_id = cs.rdb$character_set_id)
