以下是官方文档说明:

1. Command line.ITPUB个人空间lf;TEx
Enclose the connect string with a single quote character:ITPUB个人空间/P$WI!o'U3?/Q6k
Windows:ITPUB个人空间 ? Box$k&]C.}t z*P p
D:\> exp 'sys/change_on_install@instance as sysdba' tables=scott.emp
o([&{ PD6@sH-R!q1f}0Unix (you need to 'escape' the single quote):
-l"ct#|dg{Qd'?N0> exp \'sys/change_on_install@instance as sysdba\' tables=scott.emp
$I3R.McBa6L0q0VMS (use [double_quote][single_quote]...[single_quote][double_quote]):
"s&O"} v{$l+P0$ exp "'sys/change_on_install@instance as sysdba'" tables=scott.emp
mY8LH,g4Vl0Note that this VMS syntax is also a valid syntax on Unix and on Windows.

2. InteractiveITPUB个人空间Ng$EY-[^H
Do not specify any connect string on the command line, so you will be prompted to enter it. E.g.:

> exp tables=scott.emp

?&}D!il!e^6{-g0You can also specify the username in the parameter file. In this situation, you have to enclose the connect string with a double quote character. However, to prevent possible security breaches we advice you to stop using the USERID parameter in a parameter file.

4. Remarks.
Rz3Zr&pDo0Remark 1. If you have setup operating system authentication, it is not necessary to specify the SYS schema name, and password. E.g.:

> exp "'/@instance as sysdba'" tables=scott.emp

Remark 2. In addition, if you have set the environment variable TWO_TASK (on Unix) or LOCAL (on Windows) or on the server where the database is installed you have set ORACLE_HOME and ORACLE_SID, it is not necessary to specify the @instance. E.g.:

> exp "'/ as sysdba'" tables=scott.emp

Remark 3. The export parameters FLASHBACK_SCN and FLASHBACK_TIME cannot be used if the user that invoked the export is connected AS SYSDBA.
