Is it possible to query uncommitted data of a different session? For interactive debugging purposes I'm wondering whether it's possible to query the data another session has currently put into the database but not yet committed.

Say I have an my application open in a debugger and when I'm stopped in a certain breakpoint I would like to check interactively what the session of the app "is seeing" via simple queries from SQLDeveloper (or sqlplus).

Is this possible with Oracle XE? (As it is for debugging, there's no DBA or security constraints.)
no, "Oracle Database doesn't use dirty reads, nor does it even allow them"
