Concat two values using sqlldr throws error - oracle

Question

I have a table to which i want to load data using sqlldr,
The DDL of the table is as below,
create table abc.AccountDataDump (
CIF_ID varchar2(20),
ACCOUNT_NO varchar2(30),
TURNOVER number(15,2),
CASH_WITHDRAWAL number(15,2),
CASH_DEPOSIT number(15,2),
MONTH number(2),
YEAR number(4) );
I have the ctl file as below,
LOAD DATA
INFILE '/home/sijo/Downloads/testcash/CXPS_CASHDATA_MONTHLY_APR21.TXT'
badfile '/home/sijo/Downloads/testcash/cash.bad'
discardfile '/home/sijo/Downloads/testcash/cash.rej'
TRUNCATE INTO TABLE CXPSADM_sijo_47z50.AccountDataDump
FIELDS TERMINATED BY '~|'
TRAILING NULLCOLS
(
"CIF_ID",
"ACCOUNT_NO" "A_F_||:ACCOUNT_NO",
"TURNOVER",
"CASH_WITHDRAWAL",
"CASH_DEPOSIT" ,
"MONTH" ,
"YEAR"
)
Basically i am trying to prepend 'A_F_' to the "ACCOUNT_NO" but it is throwing the error as below. The account number in the in file is proper
"Record 1: Rejected - Error on table CXPSADM_SIJO_47Z50.ACCOUNTDATADUMP, column "ACCOUNT_NO".
ORA-00984: column not allowed here"
If i replace "ACCOUNT_NO" "A_F_||:ACCOUNT_NO", with just "ACCOUNT_NO", then it is working fine. Please help

Answer 1

Replace
"ACCOUNT_NO" "A_F_||:ACCOUNT_NO",
by
ACCOUNT_NO "'A_F_'||:ACCOUNT_NO",
