Need to Skip the fields duaring the data upload by SQL*Loader.

Question

Hi all,
I am not able to get how to skip some fileds in the file while uploading it thru SQL*Loader. Let us have a look the below scenario.
The table has 4 columns. but in the input file came up with 6 fields. Let us assume the four fields came as first in the order. Then, we can populate the data into the 4 columns of the table. At the same time we want to skip the remaining fields. Even those fields/columns are no longer available in the database table.
For example:
create table data_temp(sno number,name varchar2(10 char),sex char(1),loc varchar2(20 char));
Data file
sno,name,sex,loc,organization,contact
1,ram,M,India,HP,998976789
2,Shesha,M,India,IBM,7890808098
Control_file
OPTIONS(SKIP=1)
LOAD DATA
INFILE *
APPEND INTO TABLE data_temp
FIELDS TERMINATED BY ',' optionally enclosed by '"'
TRAILING NULLCOLS
sno "trim(:sno)",
name "SUBSTR(trim(:name),1,20)" ,
sex "SUBSTR(trim(:sex),1,1)",
loc "SUBSTR(trim(:loc),1,20)" ,
Please suggest me how to implement the above scenario in the control file.
Thanks in Advance!!

Use FILLER. Control file:
OPTIONS(SKIP=1)
LOAD DATA
INFILE *
APPEND INTO TABLE data_temp
FIELDS TERMINATED BY ',' optionally enclosed by '"'
TRAILING NULLCOLS
sno "trim(:sno)",
name "SUBSTR(trim(:name),1,20)" ,
sex "SUBSTR(trim(:sex),1,1)",
loc "SUBSTR(trim(:loc),1,20)" ,
organization filler,
contact filler
begindata
sno,name,***,loc,organization,contact
1,ram,M,India,HP,998976789
2,Shesha,M,India,IBM,7890808098
{code}
Now:
{code}
SQL> create table data_temp(sno number,name varchar2(10 char),sex char(1),loc varchar2(20 char));
Table created.
SQL> host sqlldr scott/tiger control=c:\temp\vissu.ctl log=c:\temp\vissu.log
SQL> select * from data_temp
  2  /
       SNO NAME       S LOC
         1 ram        M India
         2 Shesha     M India
SQL>
{code}
SY.
