How to Cast VARCHAR2 to TIMESTAMP(6) In Select Statement In Oracle?

Dear Experts,

I have a table with a field varchar2(24) with values like: '2012-09-27 01:40:31.0' (I think trailing spaces exist as well)

I want to perform insert into table select that field but the corresponding field in the target table is type TIMESTAMP(6)

How can I achieve this?

You just need to include a to_timestamp function on the character field.

insert into mytab (col1) select to_timestamp(col2, 'yyyy-mm-dd hh24:mi:ss.ff') from mytab;

If for any reason a value is not in that specific format, you will get an error.
