oracle sqlloader导入时报ORA-01830解决过程

目标：
将/home/oracle/xfsqlldr.csv导入到新建的CHOICE.T_LOAN_ANNUAL_CUSTNO表中。

新建表：
create table CHOICE.T_LOAN_ANNUAL_CUSTNO(
LOANNO VARCHAR2(200)  ,
FUNDCUSTNO VARCHAR2(200)  ,
DATEDATE DATE  ,
DATETYPE VARCHAR2(2)  ,
IS_DEL  VARCHAR2(1) DEFAULT '0' not null,
OITIME DATE DEFAULT sysdate not null,
OUTIME DATE DEFAULT sysdate not null); 处理文本，将标题行去掉
sed -i '1d' xfsqlldr.csv
more xfsqlldr.csv |wc -l
37291

编辑sqlloader控制文件
vi /home/oracle/xfsqlldr.ctl

load data
infile '/home/oracle/xfsqlldr.csv'
insert into table choice.T_LOAN_ANNUAL_CUSTNO
fields terminated by ','
OPTioNALLY ENCLOSED BY '"'
(    
    LOANNO,
    FUNDCUSTNO,
    DATEDATE,
    DATETYPE
) sqlloader导入：
sqlldr "'/as sysdba'" ROWS=10000 control=/home/oracle/xfsqlldr.ctl LOG=/home/oracle/xfsqlldr.log   

报错：
value used for ROWS parameter changed from 10000 to 248
Record 1: Rejected - Error on table CHOICE.T_LOAN_ANNUAL_CUSTNO, column DATEDATE.
ORA-01830: date fORMat picture ends before converting entire input string

Record 2: Rejected - Error on table CHOICE.T_LOAN_ANNUAL_CUSTNO, column DATEDATE.
ORA-01830: date format picture ends before converting entire input string

Record 3: Rejected - Error on table CHOICE.T_LOAN_ANNUAL_CUSTNO, column DATEDATE.
ORA-01830: date format picture ends before converting entire input string

Record 4: Rejected - Error on table CHOICE.T_LOAN_ANNUAL_CUSTNO, column DATEDATE.
ORA-01830: date format picture ends before converting entire input string

Record 5: Rejected - Error on table CHOICE.T_LOAN_ANNUAL_CUSTNO, column DATEDATE.
ORA-01830: date format picture ends before converting entire input string

导入的时间列是如下格式：
2017/9/1 16:31:25.202000
秒后面的202000不能识别。

修改导入控制文件：
load data
infile '/home/oracle/xfsqlldr.csv'
insert into table CHOICE.T_LOAN_ANNUAL_CUSTNO
fields terminated by ','
OPTIONALLY ENCLOSED BY '"'
(    
    LOANNO,
    FUNDCUSTNO,
    DATEDATE "to_date(substr(:DATEDATE,'0',instr(:DATEDATE,'.')-1),'yyyy-mm-dd hh34:mi:ss')",
    DATETYPE
)

select to_date(substr('2017/9/1 16:31:25.202000','0',instr('2017/9/1 16:31:25.202000','.')-1),'yyyy-mm-dd hh34:mi:ss') from dual; sqlloader再次导入：
sqlldr "'/as sysdba'" ROWS=10000 control=/home/oracle/xfsqlldr.ctl LOG=/home/oracle/xfsqlldr.log
