Hello!


My data file contains records with RECORD_TYPE '01', '02', '03' and '04' in position (30:31)
I use sql loader to load this data into a table. I need to load ONLY rows with RECORD_TYPE ='04'. I have to output all the other rows into a file, so I decided to use DISCARD file.
Now, those with RECORD_TYPE ='4' have to be loaded into different columns depending on the value in position (267:268).

So, my ctl file should look something like:

WHEN (30:31) = '04'

into table MYDATA
WHEN (267:268) != 'O '

into table MYDATA
WHEN (267:268) = 'O '

and whatever is not '04' goes to discard file.

I tried to use

into table MYDATA
WHEN (30:31) = '04' and (267:268) != 'O '

into table MYDATA
WHEN (30:31) = '04' and (267:268) = 'O '

but I don't get the right result in terms of the discard file.

Is there any way to put together all these conditions?
Please advice

THanks!

If raw data file resides on DB Server, EXTERNAL TABLE would be easier alternative

Maybe if you post us, CREATE TABLE statements, actual control file, a sample of data, and FINAL desired result for these data we can help.

In the following demonstration, I used (10:11) and (17:18) instead of your positions to limit the length of test data for easier reading. It appears that the discard file is as expected. Please indicate what you expect instead.

-- data_file.dat:
abcdefghi04lmnopqrstuvwxyz
abcdefghi04lmnopO stuvwxyz
abcdefghi01lmnopqrstuvwxyz
abcdefghi02lmnopO stuvwxyz


-- test.ctl:
load data
infile data_file.dat
into table a_table
when (10:11) = '04' and (17:18) != 'O '
fields
(record_type position (10:11),
not_o position (17:18))
into table a_table
when (10:11) = '04' and (17:18) = 'O '
fields
(record_type position (10:11),
is_o position (17:18))


-- table, load, and resulting data in table:
SCOTT@orcl_11gR2> create table a_table
  2    (record_type  number,
  3  	not_o	     varchar2(2),
  4  	is_o	     varchar2(2))
  5  /

Table created.

SCOTT@orcl_11gR2> host sqlldr scott/tiger control=test.ctl log=test.log discard=test.dsc

SCOTT@orcl_11gR2> select * from a_table
  2  /

RECORD_TYPE NO IS
----------- -- --
          4 qr
          4    O

2 rows selected.


-- test.dsc:
abcdefghi01lmnopqrstuvwxyz
abcdefghi02lmnopO stuvwxyz
