我有这个：

import Database.HDBC.Sqlite3
import Database.HDBC

为了转换从数据库中获取的行，我使用这个：

convertFromSql :: [SqlValue] -> [String]
convertFromSql [name, address, number, postal, city, country] = 
  [cName, cAddress, cNumber, cPostal, cCity, cCountry] where 
      cName     = (fromSql name) 
      cAddress  = (fromSql address) :: String 
      cNumber   = (fromSql number) :: String 
      cPostal   = (fromSql postal) :: String 
      cCity     = (fromSql city) :: String 
      cCountry  = (fromSql country) :: String

所有作品，但我可以例如map从fromSql获取的条目列表中sql吗？也许是一个远景：zip带有类型列表的映射列表，所以上面的代码更简洁？
