如何在linux上使用包含@的密码和sqlplus 18、19或21？

Question

I have ORACLE account with at sign (@) into password.

I was using sqlplus 12 and I can handle this special character with this syntax :

sqlplus 'USER/\"@PWD\"@SERVER:1521/BASE'

Using now sqlplus 19, this doesn't work anymore. And after many tests (sqlplus v18 v19 and v21) on multiple OS (RHEL7 RHEL8 CentOS7), the problem is the same. I've tested a lot of escape methods and search all over internet without finding anything that works.

The problem seems specific to @ sign, I can escape a ! with a \\ for example.

EDIT : I need to automate this, so solution with human interaction are not solution to my problem.

Answer 1

You can overcome this issue by connecting inside sqlplus , which by the way is much better if you want to encapsulate the connection inside a shell script.

Let me show you ( Oracle 19c over Red Hat 7 )

SQL> select version from v$instance ;

VERSION
-----------------
19.0.0.0.0

SQL> create user test identified by "Ora@xde1" ;

User created.

SQL> grant connect to test ;

Grant succeeded.

If you connect in command line, it does not work

sqlplus test/"Ora@xde1"

Version 19.3.0.0.0

ERROR:
ORA-12154: TNS:could not resolve the connect identifier specified

But, if you connect inside, it does work

sqlplus /nolog

SQL> conn test/"Ora@xde1"
Connected.
SQL> select 1 from dual ;

         1

         1

Based on @Roberto Hernandez's answer, I've used his solution modified a bit to work inside script without the need to type password interactively :

sqlplus /nolog << EOF\\nconn /""@:1521/\\n@""
