How to Check the Oracle Database Version

It’s essential to manage an Oracle Database by checking its version. Knowing the version can help with compatibility issues, or if certain features are available. Here, we’ll explore how to check the Oracle Database version.

Using SQL*Plus is one way. It’s a command-line tool used to interact with Oracle databases. Connect to the database and use this query:

SELECT * FROM V$VERSION;

It’ll show details like Oracle Database version and Oracle Application Express (APEX) version.

Another way is to query V$INSTANCE. This view has info on the instance running on the database server. This query will show instance name, number, startup time, and database version:

SELECT * FROM V$INSTANCE;

The third method: use Enterprise Manager. It’s a web-based interface for managing and monitoring Oracle databases. Access EM, navigate to the target database’s home page, and select “Enterprise.” You’ll get comprehensive info about the database configuration, including its version.

Fun Fact: Oracle Database was first introduced in 1979. Larry Ellison, Bob Miner, and Ed Oates created it.
