What Brandon posted is probably the best you can do, at least without some sort of audit trail, which, if you're asking the question after the fact, is probably not available. 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.
