Selective load in external table

Question

Hi all,
I need to load data into my external table based on conditions. If i use the 'load when' im able to load the data into the table but my requirement is to load data into different columns of the same table based on the conditional "when" clause.
This is equivalent to wht we do in .ctl file using loader..Th scenario being:
LOAD DATA     
INFILE '/m018/applmgr/ERP1/modap/1.0.0/bin/BNKSTMT260508.txt'                                   
APPEND
INTO TABLE                                   
MODAP_IN_BNK_RECON_TBL     
WHEN record_type = '01'
FIELDS TERMINATED BY ','                              
OPTIONALLY ENCLOSED BY '"'                              
TRAILING NULLCOLS                                   
(RECORD_TYPE POSITION(1)
,SENDER_IDENTI
,RECEIVER_IDENTI
     ,FILE_CREATION_DATE DATE "YYMMDD" NULLIF FILE_CREATION_DATE=BLANKS
     ,FILE_CREATION_TIME
     ,FILE_SEQ_NO
     ,RECORD_LENGTH
     ,BLOCKING_FACTOR
     ,VERSION_NO
INTO TABLE                                   
MODAP_IN_BNK_RECON_TBL     
WHEN record_type = '02'
FIELDS TERMINATED BY ','                              
OPTIONALLY ENCLOSED BY '"'                              
TRAILING NULLCOLS                                   
(RECORD_TYPE POSITION(1) "TRIM(:RECORD_TYPE)"
,RECEIVER_IDENTI "TRIM(:RECEIVER_IDENTI)"
,ORIGINATOR_IDENTI "TRIM(:ORIGINATOR_IDENTI)"
     ,GROUP_STATUS "TRIM(:GROUP_STATUS)"
     ,AS_OF_DATE DATE "YYMMDD" NULLIF AS_OF_DATE=BLANKS
     ,AS_OF_TIME "TRIM(:AS_OF_TIME)"
     ,CURRENCY_CODE "TRIM(:CURRENCY_CODE)"
I want to replicate the same in external table. Please suggest me a suitable solution for this at the earliest.

Here is a sample I used:
DROP TABLE myschema.mytable;
CREATE TABLE myschema.mytable (
"ID" VARCHAR2(12),
"RESP_DOB" DATE,
"RESP_FAM_REL" VARCHAR2(5),
"PET_FIRST_NAME" VARCHAR2(11),
"PET_MIDDLE_NAME" VARCHAR2(11),
"PET_LAST_NAME" VARCHAR2(17),
"PET_SUFFIX" VARCHAR2(1)
ORGANIZATION EXTERNAL (
TYPE ORACLE_LOADER
DEFAULT DIRECTORY "MY_DIRECTORY"
ACCESS PARAMETERS(
RECORDS DELIMITED BY NEWLINE
BADFILE 'the_BAD.TXT'
DISCARDFILE 'the_DISCARD.TXT'
LOGFILE 'the_LOG.TXT'
FIELDS
MISSING FIELD VALUES ARE NULL
ID POSITION(1:12),
RESP_DOB POSITION(98:105) DATE MASK "mmddyyyy",
RESP_FAM_REL POSITION(106:110) NULLIF RESP_FAM_REL=".",
PET_FIRST_NAME POSITION(111:121) NULLIF PET_FIRST_NAME=".",
PET_MIDDLE_NAME POSITION(122:132) NULLIF PET_MIDDLE_NAME=".",
PET_LAST_NAME POSITION(133:149) NULLIF PET_LAST_NAME=".",
PET_SUFFIX POSITION(150:150) NULLIF PET_SUFFIX="."
LOCATION ('the_file.txt')
);
