To find the current version of Oracle Database, you can follow these steps:
- Log in to the database server.
- Open a command prompt or terminal window.
- Type the command "sqlplus / as sysdba" and press Enter. This will open SQL*Plus, the command-line interface for Oracle Database administration.
- Type the command "SELECT * FROM v$version;" and press Enter. This SQL statement queries the dynamic performance view v$version, which contains the version information for the database.
- Look for the row with the "PRODUCT" column value as "Oracle Database" (or similar). The corresponding "VERSION" column will display the current version of the Oracle Database installed on the server.
- Optionally, you can also note the values in the "STATUS" and "COMMENTS" columns for additional information about the database version.
- Exit SQL*Plus by typing "EXIT" and pressing Enter.

What is the relationship between the Oracle Database version and its release date?
The Oracle Database version and its release date have a direct relationship, as the version number typically corresponds to the year of release. Oracle follows a version numbering scheme that includes a three-digit number. The first digit represents the major release number, the second digit indicates the release update, and the third digit signifies the release update patchset.
For example, Oracle Database 12c, where "c" stands for "Cloud," was released in 2013. Subsequent versions like 18c, 19c, and 21c followed, each corresponding to the year of their release.
However, it's important to note that Oracle frequently provides updates and patches to enhance the functionalities and address any issues. These updates may not always align with the version numbering convention but are still crucial for maintaining and upgrading the database system.
