To identify the release of Oracle Database that is currently installed and to see the
release levels of other database components you are using, query the data dictionary
view PRODUCT_COMPONENT_VERSION. A sample query follows. (You can also query
the V$VERSION view to see component-level information.) Other product release
levels may increment independent of the database server.
COL PRODUCT FORMAT A35
COL VERSION FORMAT A15
COL STATUS FORMAT A15
SELECT * FROM PRODUCT_COMPONENT_VERSION;
It is important to convey to Oracle the results of this query when you report problems
with the software.
检查当前Oracle版本号
可通过字典表 PRODUCT_COMPONENT_VERSION 或者 V$VERSION
