hi,

i am trying to create a trigger and need help.
i have a table called MyTable with a column called InsertDate. Each time a row is inserted into MyTable table, i want the system date to be populated into InsertDate field. This way i dont have to insert the system date at the application level. The trigger will automatically insert the InsertDate.

I am very new to oracle. Thank you for your help.

Try to use default SYSDATE :

create table foo
(mydate date default SYSDATE,
id number);

insert into foo (id) values (1);

select * from foo;

if your table is already created :

alter table foo modify mydate date default SYSDATE;

I think you can use this:
insert into table(insertdatefield) values (sysdate);
or:
insert into table(insertdatefield) values (to_char(sysdate,'yyyy-mm-dd'))
