Question

As we know that sql trigger get called implicitly.
I am just wondering is it possible to call trigger explicitly in sql server?

if yes, than how?

Thanks

I suppose it depends on what you mean by calling the trigger explicitly.

You can cause a trigger to fire with no data changes to the underlying table:

create table T (ID int not null)
go
create trigger T_T on T after insert
as
    RAISERROR('Hello',10,1) WITH NOWAIT
go
insert into T(ID)
select 1 where 1=0

With the result:

Hello

(0 row(s) affected)

That being said, it’s a bit of a cheat, and in common with @Mitch Wheat, I’m wondering why you’d attempt to do this. If “explicitly calling the trigger” is part of your solution to a problem, then a) It’s probably the wrong solution, and b) We might be able to suggest a better one, if we know what the problem is.
