How to Retrieve the Current SCN

edited Nov 10, 2008 5:24PM in Database Administration (MOSC) 2 commentsAnswered
Hi Expert 

Under an Oracle session in Oracle10g, I want to retrieve the SCN value for each transaction or request.

For a logical transaction involving any row change or row lock, it implies the start of a logical transaction. It is possible to retrieve the current SCN value from V$TRANSACTION view.

But for a request purely involving SQL statements only, it cannot refer to V$TRANSACTION view.

Will a unique SCN be assigned for SQL statement execution? If yes, how to get the SCN value?

If a session continually execute several SQL statements, does it use the same SCN while SQL execution?

Howdy, Stranger!
