各類問題：

1.EXP-00091: EXP-00091: Exporting questionable statistics 

指定Linux系統的NLS_LANG環境變量爲數據庫的數據集
1）查詢數據庫的字符集（方法不少只用一種）
SQL> select userenv('language') from dual;
USERENV('LANGUAGE')
----------------------------------------------------
AMERICAN_AMERICA.ZHS16GBK

2）設置Linux操做系統的NLS_LANG環境變量
[oracle]$export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
Window系統的環境變量的修改方法是：
C:\>set NLS_LANG=AMERICAN_AMERICA.ZHS16GBK

You can let Export prompt you for parameters by entering the EXP
command followed by your username/password:

     Example: EXP SCOTT/TIGER

Or, you can control how Export runs by entering the EXP command followed
by various arguments. To specify parameters, you use keywords:

     Format:  EXP KEYWORD=value or KEYWORD=(value1,value2,...,valueN)
     Example: EXP SCOTT/TIGER GRANTS=Y TABLES=(EMP,DEPT,MGR)
               or TABLES=(T1:P1,T1:P2), if T1 is partitioned table

USERID must be the first parameter on the command line.

上回的狀況是導數據、發現源端和目標端表結構不一致（目標端多了一個時間戳字段） 在源端建了一個臨時表（和目標端的表結構一致） 而後使用
insert into PM_NEXT_RISK_INFO0719
(id, pk_id, updatetime)
select id, pk_id, '2017-07-20' from PM_NEXT_RISK_INFO
