SQLLDR导入乱码问题的解决

处理过程:

1、本地建立控制文件

load data

infile 'd:\TMP_KAITOUSHUJU.csv'

into table TMP_KAITOUSHUJU

fields terminated by ','

(TRADE_CO,FULL_NAME,CUSTOMS_CODE,CO_CLASS,VALID_DATE,RG_DATE,ADDR_CO,BUSI_TYPE,CONTAC_CO,TEL_CO,LAW_MAN,LAW_MAN_TEL,CO_TYPE,BREAK_LAW_TIME1,BREAK_LAW_TIME2,INSPECT_TIME,COP_MODIFY_DATE)

2、WINDOWS下运用如下命令执行导入

sqlldr userid=test/test@PORTGB control=d:/TMP_KAITOUSHUJU.ctl log=d:/SQLLOAD.log

3、导入出错，提示部分列为空，查语法后改正控制文件如下

load data
infile 'd:\TMP_KAITOUSHUJU.csv'
into table TMP_KAITOUSHUJU
fields terminated by ','
trailing nullcols --将所有不在纪录中的指定位置的列当作空值
(TRADE_CO,FULL_NAME,CUSTOMS_CODE,CO_CLASS,VALID_DATE,RG_DATE,ADDR_CO,BUSI_TYPE,CONTAC_CO,TEL_CO,LAW_MAN,LAW_MAN_TEL,CO_TYPE,BREAK_LAW_TIME1,BREAK_LAW_TIME2,INSPECT_TIME,COP_MODIFY_DATE)

4、导入成功，但打开一看乱码

通过select * from v$nls_parameters; 查看NLS_CHARACTERSET为AL32UTF8，

而我本机是GBK，于是本机通过DOS窗口进行如下设置：

set NLS_LANG=AMERICAN_AMERICA.AL32UTF8

同时更改控制文件如下：

load data
CHARACTERSET AL32UTF8
infile 'd:\TMP_KAITOUSHUJU.csv'
into table TMP_KAITOUSHUJU
fields terminated by ','
trailing nullcols --将所有不在纪录中的指定位置的列当作空值
(TRADE_CO,FULL_NAME,CUSTOMS_CODE,CO_CLASS,VALID_DATE,RG_DATE,ADDR_CO,BUSI_TYPE,CONTAC_CO,TEL_CO,LAW_MAN,LAW_MAN_TEL,CO_TYPE,BREAK_LAW_TIME1,BREAK_LAW_TIME2,INSPECT_TIME,COP_MODIFY_DATE)
