sql command from a command shell

Hello Forum,

I need to run an sql command from a unix shell command line with without loging into sqlplus and I can not use a script.

When I try something like

sqlplus -S login/password select * form dual

I get an error messages

-H Displays the SQL*Plus version and the
usage help.
-V Displays the SQL*Plus version.

Usage 2: sqlplus [ [] [] [] ]

is: [-C ] [-L] [-M ""] [-R ] [-S]

-C Sets the compatibility of affected commands to the
version specified by . The version has
the form "x.y[.z]". For example, -C 10.2.0
-L Attempts to log on just once, instead of
reprompting on error.
-M "" Sets automatic HTML markup of output. The options
have the form:

-R Sets restricted mode to disable SQL*Plus commands

Runs the specified SQL*Plus script from a web server (URL) or the
local file system (filename.ext) with specified parameters that
will be assigned to substitution variables in the script.

When SQL*Plus starts, and after CONNECT commands, the site profile
(e.g. $ORACLE_HOME/sqlplus/admin/glogin.sql) and the user profile
(e.g. login.sql in the working directory) are run. The files may
contain SQL*Plus commands.

Refer to the SQL*Plus User's Guide and Reference for more information.


Is this even possible?
Can I pass on the select statement without having to encapsulate it on a sql script?

Hit the submit button prematurely as here's another way of doing the same thing:

# echo 'select * from dual;' | sqlplus -S login/password

Try this:

echo "select * form dual" | sqlplus -S login/password


Re: sql command from a command shell

Sanman and heuvel,

Both options works and the one that best fit what I need is
echo "select * from dual;"|sqlplus -S login/password@.

Re: sql command from a command shell

Just be aware of the fact that when you run this comand the user/password is shown in the process list. This could be a security issue.

It would be better if you used the user/password as part of the piped input.

sqlplus -S <username/password@DB
select * from dual;

sqlplus -S </ as sysdba
select * from dual;

For this specific request it is no big danger, but this might be important if you run a task that need some runtime.

Re: sql command from a command shell

This is a good point.

thanks Tor-Arne.
