Hi there,
Another way that I use which I think will do the same thing is:
--Disable all triggers
sp_msforeachtable "ALTER TABLE ? Disable TRIGGER all"
Then when your ready to enable them again:
--Enable all triggers
sp_msforeachtable "ALTER TABLE ? Enable TRIGGER all"
I've used this plenty of times in SQL2005 and although I haven't tried in 2008 as yet, I expect it will work.
