EXP-00091:Exporting questionable statistics

今天在oracle上做exp导出的时候报exp-00091;
查了下是服务端跟客户端的字符集不一致导致的

服务端字符集查询SQL:

select userenv('language') from dual;

执行过程如下:

E:\data>exp userid=mig/mig tables=T_CUSTOMER,T_PHONE,T_CUSTOMER_PHONE
 file=e:\data\pub.dump  log=e:\data\pub.log buffer=40960000 grants=n indexes=n t
riggers=n constraints=n

最后提一下,utf8跟al32utf8字符集是不一样的,好吧,mark一下!
