  Is there an "easy/quick" way to determine inside the trigger itself whether it is being fired because of an Insert or because of an Update when a trigger has been defined for Insert, Update?

  Without inquiring whether a row exists or not, is there a system variable that can determine this?

  If your trigger is For Update, Insert

  there is not any system information identifying what action caused the trigger to fire.

  You could duplicate your code, and create 1 trigger for insert, and 1 trigger for update, or test for Existing rows as you mentioned.

  You could do something like:

  DECLARE @operation as Varchar(10);

  DECLARE @Count as int;

  SET @operation = 'Inserted';

  SELECT @Count = COUNT(*) FROM DELETED;

  if @Count > 0

  BEGIN

  SET @operation = 'Deleted';

  SELECT @Count = COUNT(*) FROM INSERTED;

  IF @Count > 0

  SET @operation = 'Updated'

  END

  HTH,
