Where Clause SQL Loader

Question

Hi,
Please could someone give me the syntax for expressing a where clause in SQL Loader control file? as an example i only want the data in the columns to be uploaded where person_id matches the person_id already present in the table.
My control file is below which needs amending to include a 'Where'. The append will also need changing i assume.
load data
infile '/app/DEV/appl/xxcpp/11.5.0/bin/TEST.csv'
APPEND
into table XXCPP_SQL_LOADER_TEST
fields terminated by "," optionally enclosed by '"'
( PERSON_ID, EMP_NAME, EMP_NUMBER, START_DATE DATE "fmDD/MM/RRRR" )
Many Thanks

SQL*Loader has very limited conditional load capabilities. WHEN clause does not support OR (and it is documented). Anyway, you could do the following. Control file:
load data
infile *
APPEND
into table XXCPP_SQL_LOADER_TEST
When Person_id = '1'
fields terminated by "," optionally enclosed by '"'
( PERSON_ID POSITION(1), EMP_NAME, EMP_NUMBER, START_DATE DATE "fmDD/MM/RRRR" )
into table XXCPP_SQL_LOADER_TEST
When Person_id = '2'
fields terminated by "," optionally enclosed by '"'
( PERSON_ID POSITION(1), EMP_NAME, EMP_NUMBER, START_DATE DATE "fmDD/MM/RRRR" )
into table XXCPP_SQL_LOADER_TEST
When Person_id = '3'
fields terminated by "," optionally enclosed by '"'
( PERSON_ID POSITION(1), EMP_NAME, EMP_NUMBER, START_DATE DATE "fmDD/MM/RRRR" )
begindata
1,A,11,13/01/2011
2,B,12,13/01/2011
3,C,13,13/01/2011
4,D,14,13/01/2011
5,D,15,13/01/2011
{code}
Now:
{code}
SQL> select * from XXCPP_SQL_LOADER_TEST;
no rows selected
SQL> host sqlldr scott/tiger control=c:\temp\XXCPP_SQL_LOADER_TEST.CTL log=c:\temp\XXCPP_SQL_LOADER_TEST.LOG
SQL> select * from XXCPP_SQL_LOADER_TEST;
PERSON_ID EMP_NAME   EMP_NUMBER START_DAT
         1 A                  11 13-JAN-11
         2 B                  12 13-JAN-11
         3 C                  13 13-JAN-11
