Question : Trigger for INSERT, UPDATE, DELETE - determine which event happened within the trigger?

I'd like to implement a single trigger on a table for INSERT, UPDATE, DELETE. Within that trigger, how can I determine which event caused it to fire? For example, in pseudo-code

Thanks

Code Snippet:

         
           
           
             create trigger [dbo].t_mytrigger
   on
      [dbo].[mytable]
 for
    INSERT, UPDATE, DELETE
AS
    -- begin pseudo code
 
    IF INSERT THEN
              DO ONE THING
    IF UPDATE THEN
            DO OTHER THINGS
     IF DELETE THEN
           DO YET ANOTHER THING

Answer : Trigger for INSERT, UPDATE, DELETE - determine which event happened within the trigger?

well you can do it this way than:

if (select count() from inserted) <> 0 and (select count() from
deleted) = 0 --insert
begin

end
if (select count() from inserted) <> 0 and (select count() from
deleted) <> 0 --update
begin

end
if (select count() from inserted) = 0 and (select count() from
deleted) <> 0 --delete
begin

end
