If you have already loaded the table it reads to me like all you need to do is update the date_col for the time value held in the varchar2 column. If the time is formatted like "12:15:30" then something like:

update my_table
set date_col = to_date(to_char(date_col,'YYYYMMDD')||' '|| time_col,'YYYYMMDD HH24:MI:SS')
where ......

Depending on the exact format of the data, and my nearly limitless ability to mistype statements some minor modification may be required.

Subject: migrating a date and varchar field into 1 date field

I'm migrating some old data from a progress database. I was given a data extract that was sql loaded into Oracle. I have two columns date_col (has the proper month,day,year) and is a date type time_col(has the proper time in minutes, seconds, etc...) and is a varchar field
anyway to dummy it up so I can get both of these into the same column? the date_col has an incorrect time of day.
