Get the Oracle Version using CMD - oracle

Question

Is there is any command to find my installed oracle version from windows command prompt. (just like java -version..)

Answer 1

You need to locate ORACLE_HOME directory, to set it as environment variable and then to run opatch:
set ORACLE_HOME=...
"ORACLE_HOME"\OPatch\opatch lspatches
This command lists the installed patches with the Oracle major version.

Answer 2

You can use the below to get the database version by navigating to the ORACLE_HOME directory
$ORACLE_HOME\OPatch\opatch lsinventory | find "Oracle Database"

Answer 3

Well, that depends on what you really have.
If you have installed Oracle onto your PC (such as my 11gXE), then you could try sqlplus -v:
c:\Temp>sqlplus -v
SQL*Plus: Release 11.2.0.2.0 Production
11.2.0.2.0; is that really so?
c:\Temp>sqlplus scott/tiger
SQL*Plus: Release 11.2.0.2.0 Production on Sri Svi 6 07:40:29 2020

Yes, it is. I use SQL*Plus 11.2.0.2.0 which connects me to 11.2.0.2.0 database.
However, if I don't have Oracle installed on my PC but it is somewhere on database server and I access it via network, then it won't work because it'll display SQL*Plus (i.e. client installed on my PC), not database version. Besides, I can have several clients installed, so it depends on which sqlplus executable I ran.
Database version - in such a case - can't be retrieved from operating system command prompt only (at least, I don't know how to do it). You can obtain it by connecting to the database itself, e.g.
Client version:
M:\>sqlplus -v
SQL*Plus: Release 11.2.0.1.0 Production
ORCL database version is 11.2.0.4.0
M:\>sqlplus scott/tiger#orcl

ORCL2 database version is 10.2.0.5.0:

When you're in SQL*Plus, query v$version, e.g.
SQL> select * From v$version where rownum = 1;
BANNER CON_ID

which shows that I'm currently connected to 12.2.0.1.0.

Answer 4

This code allows you to display only the version of the database.
#echo off
set user_name=scott
set password=tiger
set net_service_name=edcu
set sql=select version from PRODUCT_COMPONENT_VERSION where rownum=1;
(echo conn %user_name%/%password%#%net_service_name%
echo set heading off
echo %sql%
echo exit) |sqlplus -s /nolog
For example output
D:\upwork\stackoverflow\get_version_oracle>get_oracle_version.bat
11.2.0.3.0
