Re: counting inserts/updates when doing a merge

Interesting question.  Here is one way I can think to do it:

declare @minserts int, @mupdates int
set @minserts = 0
set @mupdates = 0
merge into myhist as h
    using mytrans as t
      on h.pkey = t.pkey
when matched then update set h.description = t.description, @mupdates = @mupdates + 1
when not matched then insert (pkey,description) values (t.pkey,t.description)
 
select @minserts = @@rowcount - @mupdates
print "UPDATES:  %1!   INSERTS:  %2!",@mupdates,@minserts
