Mark: Can you post maybe 100 or so to give us a little more sample to go on? Or send a spreadsheet to those of us who like these things with all of the OBJIDs and dates (how many are there?)? Rocky -----Original Message----- From: accessd-bounces at databaseadvisors.com [mailto:accessd-bounces at databaseadvisors.com] On Behalf Of Mark A Matte Sent: Wednesday, March 21, 2007 12:26 PM To: accessd at databaseadvisors.com Subject: Re: [AccessD] OT(kinda): Crack Code This thing reminds me of the crypto toy at the end of the Davinci Code(8 little wheels with letters and numbers). I think the sequence is jumbled as well. In trying to solve I started dissecting a looking at individual characters. I looked at the 8th(last character) for frequency. The distribution didn't make much sense(listed below). So I looked at the least, "C" to try and isolate a pattern...and found it was only the last char on 9/12/2001 and 9/19/2001...and not for all of the records. I might pass it on to the University...but I'll probably just let it die...like it should have a long time ago. The only reason they are still using it is that no one understood the relationships of the tables. After I discovered that the fields OBJID in the different tables were not necessarily related...and that the 1 table with 2 keys in it...was actually related to itself 3 or more times...we made leaps and bounds...for the first time they could say definitively that they were missing records. Any way...thanks again everyone. Mar A.
