DB_VERSION
Finding database version with DBMS_UTILITY.DB_VERSION
This very short article comes from a post to comp.databases.oracle.server in answer to a question on how to get the database version using PL/SQL. This simple example program in PL/SQL using DBMS_UTILITY.DB_VERSION shows how the version and compatibility can be found. Here it is:
SQL> set serveroutput on size 1000000
SQL> l
1 declare
2 lv_version varchar2(100):='';
3 lv_compat varchar2(100):='';
4 begin
5 dbms_utility.db_version(lv_version,lv_compat);
6 dbms_output.put_line('version = '||lv_version);
7 dbms_output.put_line('compatability = '||lv_compat);
8 exception
9 when others then
10 dbms_output.put_line(sqlerrm);
11* end;
SQL> /
version = 9.2.0.1.0
compatability = 9.2.0.0.0

Running my privilege check script for dbms_utility shows that it is available for public use:

That's , a simple example of the use of the built in package DBMS_UTILITY.DB_VERSION available for public use. DBMS_UTILITY.DB_VERSION is an alternative to using simple SQL commands to get the compatibility from v$parameter and the versions from v$version techniques.
