    @msgnum = 60000,
    @severity = 16,
    @msgtext = N'The item named %s already exists in %s.', 
    @lang = 'us_english';

-- Create a localized version of the same message.
EXEC sp_addmessage

    @severity = 16,
    @msgtext = N'L''élément nommé %1! existe déjà dans %2!',

-- of the message exists.

    @msgnum = 60000,
    @lang = 'French';
