Question

I want to get the current date time every time I update or insert into this table

getdate() or systime() or CURRENT_TIMESTAMP get the date time when insert only not when update

Answer 1

You can use TRIGGER The trigger will be automatically run when insert/update happen in the table.

For example:

create table tbl1
(
    col1 int primary key,
    col2 datetime
)
go
create trigger trg01
on tbl1
for insert, update
as 
begin
   update tbl1 
   set col2 = GETDATE()
   where col1 in (select col1 from inserted)
end   
go
insert into tbl1(col1) values (1);

Answer 2

Your question is confusing, first you said, "..i want to get current date time every time i update or insert into this table.." and on the last part of your question, you said, ".. get the date time when insert only not when update .."

But give this a try, why not set a default value on the column, example:

CREATE TABLE Hello
(
    ID INT,
    DATE DATETIME DEFAULT GETDATE()
)


INSERT INTO Hello (ID) VALUES (1)
INSERT INTO Hello (ID) VALUES (2)
INSERT INTO Hello (ID) VALUES (3)
INSERT INTO Hello (ID) VALUES (4)

getdate() or systime() or CURRENT_TIMESTAMP 

These will give you the current system date time. if you want on the insert, update event capture the date time use the trigger or yourself you can get the datetime and insert into required table.
