Friends, thanks in advance.

I get data in ',' delimitted flat file with date and time fields.Date is DATE datatype and Time is TIMESTAMP datatype..I would like to store my date field with date and time without fractional seconds and time with just the time part .
My control file looks like:
LOAD DATA
infile 'test.dat'
replace INTO TABLE TEST

FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '"' TRAILING NULLCOLS
(
START_DATE DATE "dd/mm/yyyy hh24:mi:ss",
START_TIME TIME "dd/mm/yyyy hh24:mi:ss.ff1"
)

My data looks like:
03/10/2008,10:12:30.0
03/02/2008,10:15:00.9

I have to see the data as 03/10/2008 10:12:30 in the START_DATE field and 03/10/2008 10:12:30.0 in my STRAT_TIME field.

How can i concatenate these two fields,yet store them seperately?

regards,
riki.

There is no TIME datatype in Oracle.

Michel you are true .But that is the control file.If i don't store it as time how can i store the timestamp?

Pardon my ignorance.
I have just started working with oracle.

Regard,
riki.

Sorry, wrong answer for SQL*Loader.
I don't have Oracle by hand to test it but you should test a fixed-format something like:
start_date position(01:10) date "DD/MM/YYYY"
start_time position(01:22) timestamp(1)

As, afaik, you can't give a timestamp format in SQL*Loader, set your environment variable previously:
export NLS_TIMESTAMP_FORMAT='DD/MM/YYYY,HH24:MI:SS.FF1'

or the like depending on your OS and shell.

Michel

The file is ',' delimitted.And the field(s) preceeding the START_DATE are not of fixed length.

riki.

the data file is like:

How can you put this string in 11 characters?
Quote:
Time is TIMESTAMP datatype

Is it TIMESTAMP or VARCHAR2(11)?

The table is partitoned on day and earlier I was getting the date part of timestamp to be the 1st day of month irrespective of the current date.

So i wanted to get rid of the date part and changed it to VARCHAR,thinking that i have start_date field which refers to date and start_time soley dedicated for time portion.

But when using "to_date" function I doubted my previous step may be wrong.

I thought may be combining the two fields and loading may be a possible solution for the problem.

I thought of writing a PERL script which combines the two fields yet keeping them available seperately (as the flat files are sent to me by some outer source).But that may not be a good idea for me to follow as i have to load data every 5 mins (100 files at the minimum each load )

And hence here. Razz

riki.

I am not entirely sure what you want to do or why, so the following demonstrates usage of boundfiller and concatenation for loading the date and time into a date datatype, the time only into a varchar2 data type and the date time and fractional seconds into a timestamp datatype. You can use whatever pieces you decide.

-- test.dat:

It works fine on my test table .But for my original table it gives the date part correctly where as the time part it is rounding it to 12:00:00 AM

I don't know if you are still using the same table structure that you posted or if you have changed the start_time to timestamp datatype. Any calculated fields need to go at the end, after all other fields. If you are going to name your timestamp data type start_time, then you need to use filler_time or some such other name declared as boundfiller type before that, just as filler_date was declared, in order to use it in calculations. If you are still having problems, then please post all of the matching current pieces: data file, control file, table structure, select from table after loading, and sql*loader log file.

If your current data structure is:

CREATE TABLE test
  (DD               NUMBER(2),
   TYPE             VARCHAR2(12),
   NAME             VARCHAR2(23),
   ID               VARCHAR2(18),
   SYSTEM_TICKS     NUMBER(10),
   ZONE             VARCHAR2(23),
   START_DATE       DATE,
   START_TIME       TIMESTAMP)
/


then your control file should be:

LOAD DATA
infile 'test.dat'
INSERT INTO TABLE TEST
FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '"'
TRAILING NULLCOLS
(
TYPE,
NAME,
ID,
SYSTEM_TICKS,
ZONE,
filler_date BOUNDFILLER,
filler_time BOUNDFILLER,
DD "to_char(to_date(:filler_date, 'mm/dd/yyyy'),'dd')",
START_DATE "TO_DATE(:filler_date || SUBSTR (:filler_time, 1, 8), 'mm/dd/yyyyhh24:mi:ss')",
start_time "TO_TIMESTAMP(:filler_date || :filler_time, 'mm/dd/yyyyhh24:mi:ss.ff1')"
)
