SQL & PL/SQL

Dear All,

I'm struggling to load a table when the data file contains nulls for date value. i get the following error:

Record 1: Rejected - Error on table W_PARTY_PER_D, column BIRTH_DT.
ORA-01841: (full) year must be between -4713 and +9999, and not be 0

Thanks for any pointers, detials below:

My Control file is:

load data
infile '/media/sf_timv/w_party_per_d_40pc.csv'
into table w_party_per_d
fields terminated by "," optionally enclosed by '"'
( ROW_WID,
BIRTH_DT DATE "YYYY-MM-DD HH24:MI:SS" NULLIF BIRTH_DT=BLANKS,
DATASOURCE_NUM_ID,
EDUCATION_BCKGND_NAME,
INTEGRATION_ID,
MARITAL_STAT_NAME,
SEX_MF_NAME )

Table schema:

create table TTUSER.W_PARTY_PER_D (
ROW_WID NUMBER(38) DEFAULT 0 NOT NULL,
BIRTH_DT DATE,
DATASOURCE_NUM_ID NUMBER(38) NOT NULL,
EDUCATION_BCKGND_NAME VARCHAR2(50 CHAR) ,
INTEGRATION_ID VARCHAR2(80 CHAR) NOT NULL,
MARITAL_STAT_NAME VARCHAR2(80 CHAR) ,
SEX_MF_NAME VARCHAR2(50 CHAR) ,
primary key (ROW_WID));

And a snip from the data file:
