在設置Oracle密碼時,我們經常會將密碼設置的特別復雜(一般由字母、數字和特殊符號組成),值得注意的是在有特殊符號時修改密碼或著導入導出數據時會遇到很多不必要的麻煩,本文中將會對此情況進行詳細的解釋和說明:
注:本文中,將以特殊符號“/”為例。
Linux環境下,使用Oracle數據庫10g
修改密碼
[oracle@olivenan oracle]$ sqlplus ‘/as sysdba’

With the Partitioning, OLAP and Data Mining options
SQL》 alter user test identified by aa/aa;
alter user test identified by aa/aa
*
ERROR at line 1:
ORA-00922: missing or invalid option
在此使用“”
SQL》 alter user test identified by “aa/aa”;
User altered.
SQL》
[oracle@olivenan oracle]$ exp test/aa/aa file=test.dmp buffer=65536

此處應該進行轉義使用 “ ”處理密碼,使用 ‘ ’處理用戶名和密碼
[oracle@olivenan oracle]$ exp ‘test/“aa/aa”’ file=test.dmp buffer=65536
