Hi all

I have created the following simple table

create table NTE_NOTES (
nte_id int unique not null,
nte_text text not null,
nte_last_updated timestamp not null,
constraint nte_pk primary key (nte_id));

If I execute the following sql as a single transaction in the admin
interface or using JDBC it appears that the CURRENT_TIMESTAMP has the same
value for all records including the updated one. Why?

insert into NTE_NOTES (nte_id, nte_text, nte_last_updated)
values(99999,'demo study note text',CURRENT_TIMESTAMP);
insert into NTE_NOTES (nte_id, nte_text, nte_last_updated)
values(29999,'demo study note text',CURRENT_TIMESTAMP);
insert into NTE_NOTES (nte_id, nte_text, nte_last_updated)
values(39999,'demo study note text',CURRENT_TIMESTAMP);
update NTE_NOTES set nte_last_updated = CURRENT_TIMESTAMP where nte_id =
99999;
select * from NTE_NOTES;

Results from call:

29999;"demo study note text";"2006-08-10 15:34:51.593"
39999;"demo study note text";"2006-08-10 15:34:51.593"
99999;"demo study note text";"2006-08-10 15:34:51.593"

Now I am not a db expert so unless this is something to do with the
transaction I would have expected different date values.

Can anyone give me an insight?

Regards

Andy Foster
