multi languages lookup

Hi Everybody,
I would like to have lookup that linked to product attributes table shows the attribute as the the application language chosen. I have read the way of having the labels in each language as separate record and filter them by where close. However, this is not the best practice from database point of view since each record(in my case) shoud have unique Id whatever the language. . So can I have any cousmization in the reg expression to make this work to just show one language field from DB column?
