Batch update and trigger

Hi All,
I have a trigger on a table tracking changes to certain fields.
However, when I do a batch update on that field, it looks like the
trigger only gets fired once. However, I do want to track changes on
every record that the update statement touches. So, is there anyway to
make it work or is there any work around? Do I have to create a cursor
and update one record a time?
Thanks a lot,
blueyep, triggers in SQL Server are fired once per statement, not once per
row. when you describe how do you need to track changes, we might be
able to help|||what I want to do is very simple. I want to track the change to a field
in one table. if the value changes, I will insert a row in the change
log table. Basically if old field value <> new field value, insert a
row in the change log.
However, in another script, I sometimes update the field for many rows
if they meet the criteria. Therefore, I have something like UPDATE
table1 SET field1= 'Y' WHERE field2>field3. When this statement is
executed, the trigger only fired once and therefore, only one row gets
inserted into the changelog table.
I just wonder if there is anyway I can make the trigger fired for each
row without abandoning the batch update and use cursor to do update for
each individual row
Thanks a lot.|||if you don't modify the PK, that's easy:
create table seq(s_id int identity, i int)
insert into seq(i) values(1)
insert into seq(i) values(2)
insert into seq(i) values(3)
insert into seq(i) values(4)
go
create table seq_audit(s_id int, old_i int, new_i int)
go
create trigger seq_upd
on seq
for update
as
insert into seq_audit
select inserted.s_id, deleted.i, inserted.i from inserted, deleted
where inserted.s_id = deleted.s_id
go
select * from seq
s_id i
-- --
1 1
2 2
3 3
4 4
go
update seq set i=i+1 where s_id > 1
go
select * from seq_audit
s_id old_i new_i
-- -- --
2 2 3
3 3 4
4 4 5
go
drop table seq
drop table seq_audit
