推荐答案

SQL * Plus使用& 1，& 2 ...& n访问参数.

SQL*Plus uses &1, &2... &n to access the parameters.

假设您具有以下脚本test.sql:

SET SERVEROUTPUT ON
SPOOL test.log
EXEC dbms_output.put_line('&1 &2');
SPOOL off

例如，您可以像这样调用此脚本:

you could call this script like this for example:

$ sqlplus login/pw @test Hello World!

在UNIX脚本中，您通常会这样调用SQL脚本:

In a UNIX script you would usually call a SQL script like this:

sqlplus /nolog << EOF
connect user/password@db
@test.sql Hello World!
exit
EOF

，以便您的登录名/密码在其他会话的ps

so that your login/password won't be visible with another session's ps
