Selecting Database Name

From TekiWiki

To select the Oracle Database name, the most common method is:

SELECT name FROM v$database

This, however, requires special permissions to be able to read the pseudo table v$database.

The database name is part of the session context and can be selected using the following function:

SELECT sys_context('USERENV', 'DB_NAME') FROM dual

When used as part of a larger query, this does not need to join the v$database pseudo table.

This is particularly useful in packaged solutions like PeopleSoft, SAP etc. where permissions to see v$database are non-standard.
