Date/Timestamp

Question

Hi
I have a column with datatype VARCHAR2(50).
The Data inside this column is as below
2012-05-15 23:50:04.250
2012-05-15 23:52:48.023
2012-05-15 23:53:11.043
2012-05-15 23:53:58.477
I want to insert this data into another table having datatype as DATE.
Please suggest how to format this data and insert into another table.
Thanks
Jo

Answer 1

But i need the fraction as welluse TIMESTAMP, not DATE
http://psoug.org/reference/timestamp.html
/*alter session set nls_timestamp_format='YYYY-MM-DD HH24:MI:SS.FF';*/
drop table x;
create table x (y date);
insert into x select  to_timestamp('2012-05-15 23:50:04.250','YYYY-MM-DD HH24:MI:SS.FF') x from dual;
commit;
select * from x;
drop table x;
create table x (y timestamp);
insert into x select  to_timestamp('2012-05-15 23:50:04.250','YYYY-MM-DD HH24:MI:SS.FF') x from dual;
commit;
select * from x;
