Question

I have a table and a trigger

create table test(id int not null identity(1,1) primary key, data int);
create trigger insteadTestInsert ON test INSTEAD OF INSERT 
AS
BEGIN
  INSERT INTO test(data) select data FROM inserted;
END;

When trigger is enabled, the following query

declare @tmp_table table(id int, int_val int);
insert into test(data) 
output inserted.* into @tmp_table
values (10);
select * from @tmp_table;

returns id = 0, int_val = 10 .
If I disable(or drop) the trigger, the query returns the proper value of id.

How to make OUTPUT insert proper results into table variable?

Answer 1

This one actually works.

declare @tmp_table table(seq int identity, id int, int_val int);
insert into test(data) 
output inserted.data into @tmp_table(int_val)
values (11),(12),(13);

update @tmp_table set id = seq + @@identity - @@rowcount
select * from @tmp_table;
select top 2 * from test order by id desc;

The restriction is that you must NOT have any other triggers on the table test that would “corrupt” the @@identity variable.
