第二 在所在的OS上設定NLS_LANG環境變數為資料庫的資料集
A 查詢資料庫的字符集
SQL> select userenv('language') from dual;

USERENV('LANGUAGE')
----------------------------------------------------
AMERICAN_AMERICA.ZHS16GBK

SQL> select userenv('language') from dual;

USERENV('LANGUAGE')
----------------------------------------------------
SIMPLIFIED CHINESE_CHINA.ZHS16GBK

B 設定Linux作業系統的NLS_LANG環境變數到ORACLE 使用者的.bash_profile檔案中
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

#PATH=$PATH:$HOME/bin

#export PATH

export ORACLE_BASE=/u01/oracle
export ORACLE_HOME=$ORACLE_BASE/product/OraHome
export ORACLE_SID=standby
export ORACLE_OWNER=oracle
export ORACLE_TERM=vt100
export PATH=$PATH:$ORACLE_HOME/bin:$HOME/bin
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
~
".bash_profile" 20L, 423C written
 
C 或則直接設定
[oracle@standby ~]$ export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
C:\Users\QiLin>set NLS_LANG=SIMPLIFIED CHINESE_CHINA.ZHS16GBK

第三 推出當前匯出資料的使用者，再次進入就可以了
