How to give to a powershell variable only the output of my sqlplus query?-CodePudding

 $a = 'select 2 from dual' | sqlplus user/password@database.

expected result: 2

real result :

SQL*Plus: Release 19.0.0.0.0 - Production on Tue May 31 08:29:43 2022 Version 19.3.0.0.0 Copyright (c) 1982, 2019, Oracle. All rights reserved.

I would like to get only what my query returns. How do I do that?

@vonPrynz

$a = 'select 2 from dual' | sqlplus -S user/password@database.

result is empty

CodePudding user response：

You need add ';'

PS C:\> 'select 2 as result from dual;' | sqlplus -s user/password@DEV19

    RESULT
----------
         2

If you want only '2' then add this lines:

'SET FEEDBACK OFF 
set heading off
set termout OFF
SET FEEDBACK OFF
SET TAB OFF
set pause off
set verify off
SET UNDERLINE OFF
set trimspool on
set timing off
set echo off
set linesize 1000
set pagesize 100
select 2 as result from dual;' | sqlplus -s user/password@DEV19
     2
