SQLLOADER command: how to "||" constant value to the field

Question

In SQLLOADER control file, how do I CONCATENATE a constant on the loading field like the update statement in SQL
update table_A
set col_1 = "RULE" || col_1 || "; DALDAL"
I did
DESCRIPTION REF(CONSTANT 'RULE ', DESCRIPTION, CONSTANT 'DALDAL'),
or
DESCRIPTION CONSTANT 'RULE ' || :DESCRIPTION || CONSTANT "DALDAL',
both give me error.
Any idea. I'm trying to avoid run update table statement after the load.

Answer 1

Try..
DESCRIPTION "'RULE ' || :DESCRIPTION || 'DALDAL'"
.....Example...
SQL> desc t;
Name                                      Null?    Type
NAME                                               VARCHAR2(200)============Control File======================
LOAD DATA
INFILE *
REPLACE
INTO TABLE T
FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY '"'
NAME "'Mr.' || :Name || ' Jr.'"
BEGINDATA
Rajesh
{code}
After load...
{code}
SQL> select * from t;
NAME
Mr.Rajesh Jr.
{code}
