How to insert some date types with SQLLoader?

Dear Experts,

I have some files with different kinds of data and each file type has different date-time field. I want to load those files with SQLLoader to Oracle tables. In each related Oracle table, there is a field with Date type. However, in the files, representation of date-time fields differs according to file type.  For example one file type has a date-time field with data sample: "2014-11-10 01:07:57". I'will use YYYY-MM-DD HH24:MI:SS for this in control file. Unfortunately not all file types  are easy like this. (See Below) Could you please help for the following?

2014-05-09 12:14:08+02:00DST
2012-01-16 09:24:43.0
2014-11-09 04:00:00 AM
2014-11-8-16-14-55

Thanks in Advance.

Not sure I completely understand what you are asking.

Are you asking how to specify the format within the SQL*Loader control file?  That is documented here -> https://docs.oracle.com/cd/E11882_01/server.112/e22490/ldr_field_list.htm#i1016161

Or, are you asking how you can change the mask without changing the control file?  My guess on that (which I have not tested) is that you could set the NLS_DATE_FORMAT in the environment.  I believe that the default format is picked up from there, the documentation doesn't mention the default that I could see.

I actually just asked how I can represent these in TO_DATE function such as TO_DATE(VALUE, 'YYYY-MM-DD HH24:MI:SS')

The first two are timestamps, not dates, so that would be:

to_timestamp('2014-05-09 12:14:08+02:00DST', 'yyyy-mm-dd hh24:mi:sstxh:tzmtzd')
to_timestamp('2012-01-16 09:24:43.0', 'yyyy-mm-dd hh24:mi:ss.ff1')

If you are inserting into a field with a DATE datatype, the conversion should be done for you automatically.

The rest are:

to_date('2014-11-09 04:00:00 AM','yyyy-mm-dd hh:mi:ss AM')
to_date('2014-11-8-16-14-55','yyyy-mm-dd-hh24-mi-ss')


Documentation for DATE format models -> https://docs.oracle.com/cd/E11882_01/server.112/e41084/sql_elements004.htm#SQLRF00212

Thanks, and one last point: Do you mean if I insert those TimeStamp fields (first two of above) to Date field using SQLLOADER then otomatic conversion occurs?

Yes.  If you insert a timestamp into a DATE field, then an implicit conversion takes place.  Essentially the subseconds and timezone information is removed.
