How to Get Oracle Database Version?

To get the Oracle database version, you can run a SQL query against the database. Connect to the database using SQL*Plus or any other SQL client, and then execute the following query:

SELECT * FROM v$version;

This query will return information about the Oracle database version, including the version number and other details like the release number, edition, and the version of PL/SQL.

Another way to get the Oracle database version is by checking the Oracle home directory. Navigate to the Oracle home directory where the database is installed, and look for a file named "release.txt". This file contains information about the database version, release number, and other details.

By using either of these methods, you can easily find out the version of the Oracle database that you are using.
