當Oracle數據庫用戶的密碼含特殊字符如 @ 時，直接使用正常的密碼輸入，由於oracle將@后的字符解析為網絡服務名而導致登陸失敗
創建一個密碼中含有特殊符號的用戶: test
SQL> create user test identified by "aba123!@#"; --用戶名：test 密碼：aba123!@# 注意創建的時候用雙引號 User created. SQL> grant create session to test; Grant succeeded.
Linux平台登錄方式：'test/"aba123!@#"'@scp --1個雙引號擴密碼，1個單引號擴 用戶名+密碼，即： '用戶名/"密碼"'@服務名
