我在Windows 8.1上安装了instantclient 12c x86
我可以从 cmd.exe 连接：
C:\Users\vagrant>sqlplus user@\"hostname:1521/SERVICE_NAME\"
SQL*Plus: Release 12.1.0.2.0 Production on Thu Dec 3 06:22:31 2015

Enter password:

Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production

OLAP,

SQL>
现在，当我从Powershell尝试同样的事情时：
我想提示输入密码。它不起作用。
PS C:\Users\vagrant> sqlplus user@\"hostname:1521/SERVICE_NAME\"
SQL*Plus: Release 12.1.0.2.0 Production on Thu Dec 3 06:30:12 2015
Copyright (c) 1982, 2014, Oracle. All rights reserved.
ERROR:
ORA-12154: TNS:could not resolve the connect identifier specified
Enter user-name:
在这里，我提供了密码并且可以正常使用
PS C:\Users\vagrant>sqlplus user/password@hostname:1521/SERVICE_NAME
SQL*Plus: Release 12.1.0.2.0 Production on Thu Dec 3 06:24:48 2015

使用Powershell的sqlplus提示输入密码的正确语法是什么？
