Firing a Trigger for Each Inserted Row

Mialem nadzieje, ze jest jakies inne rozwiazanie tego problemu. I have hope that is other solution for this problem.

That was the worse answer to someone's problem by Microsoft ever. I can't believe I bought a subsricption to this site just for that. Completely misleading to end the article with a ... one word before it actually ends.

(note: I only have a few years experience here)
I am doing the reverse of a bulk update on the table itself; it may be thought to go to the very table where there is one transaction, that affects the 'bulk insert':
-- "Othertable" is where I am 'mass' updating, this trigger can be put into something called "ThisTable"

-- example: a person deletes a record, it tags associated records, if there is no related table, the "IsOrphan" does not fire, the record is deleted.
-- note: NO RELATIONSHIPS in either table
INSTEAD of delete
AS
Declare @Rcount As int
Declare @RegID As Int


SELECT @rcount = @@rowcount
IF @rcount =0
return


SELECT @RegID= (SELECT deleted.RegID
FROM deleted)

BEGIN
SET NOCOUNT off;
UPDATE OtherTable
SET IsOrphan = 1
WHERE (OtherTable.RegID = @RegID)

How about an answer for how to do this when set based operations are not an option?
