自定义而不是更新触发器

Question

Hi i have the following Trigger:

    ALTER TRIGGER [dbo].[BOOKVERNR_UPDATE]
ON [dbo].[BUCHUNG]
INSTEAD OF UPDATE
AS

BEGIN
SET NOCOUNT ON;

        INSERT INTO [BUCHUNG] (BOOKUID, BOOKVERNR, BUCHUNGSART_ID, VERANSTALTER, PERSONAL_ID,
        OPTIONSNUMMER, BUCHUNGSSTATUS, PERSONENZAHL, SERIE, THEMA, STORNO, UPDATE_DATE, UPDATE_USER, BEMERKUNG, V_EMAIL, V_TELEFON,
        KOSTENSTELLE, SERIENBOOKUID, THEMA_ENABLED, ABTEILUNG, LIEFERRAUM, PERSONENZAHLEXTERN, ABRECHNUNG, KSTR, RECHKONTO, RECHKST, RECHDST, URSPRUNG_ORIGINAL, ORIGINAL_ID)

        SELECT i.BOOKUID, '0', i.BUCHUNGSART_ID, i.VERANSTALTER, i.PERSONAL_ID,
        i.OPTIONSNUMMER, i.BUCHUNGSSTATUS, i.PERSONENZAHL, i.SERIE, i.THEMA, i.STORNO, GETDATE(), i.UPDATE_USER, i.BEMERKUNG, i.V_EMAIL, i.V_TELEFON,
        i.KOSTENSTELLE, i.SERIENBOOKUID, i.THEMA_ENABLED, i.ABTEILUNG, i.LIEFERRAUM, i.PERSONENZAHLEXTERN, i.ABRECHNUNG, i.KSTR, i.RECHKONTO, i.RECHKST, i.RECHDST, i.URSPRUNG_ORIGINAL,
        i.ORIGINAL_ID


        FROM INSERTED i
        JOIN DELETED d ON i.ID = d.ID
        WHERE i.BOOKVERNR <> d.BOOKVERNR


SET NOCOUNT OFF;
END

The trigger copies an entire row with a new ID if an Update on "BOOKVERNR" happens. A new row is only inserted if an Update happens on "BOOKVERNR".

My Problem ist that with that trigger i can't Update the other colums except with for Example "IF UPDATE (BOOKUID)". But that is not what i want.

Is there a way to customize the trigger, so that i can Update all the other columns,without using "IF UPDATE" for each column?
