However, it's really not sufficient. I could create object A today, object B tomorrow, and drop object A the day after tomorrow. Then, Brandon's query will return yesterday's date, rather than the day before yesterday. There's no good, obvious way around this, that I can see. I'm just pointing out a possible weakness in the strategy. -Mark From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Allen, Brandon Sent: Monday, October 18, 2010 1:27 PM To: murrays@xxxxxxxxxxxxxxxxxxxx; oracle-l@xxxxxxxxxxxxx Subject: RE: How to determine when a particular schema was created within a database.
