What if you had a related table with your key, state and relation columns. In the relations column you would have 4 chars, the first two are the state, the next two are the bordering state. Tennessee would have something like the following:
Key State relation 1 TN TNAR 1 TN TNMS 1 TN TNMO 1 TN TNKY 1 TN TNNC 1 TN TNVA 1 TN TNAL 1 TN TNGA I believe this will allow you to pull surrounding states.

I need to sum /.group a set of records based on if the States (Nebraska, Arizona, New York), border one another or if a chain of bordering States can be found. So for example, NE $100.00 IA $100.00 IL $100.00 TX $200.00 AZ $350.00 CA $350.00 Group one is $300.00 (NE, IA, IL) - NE borders IA, IA borders IL - a chain Group two is $200.00 (TX) - TX does not border any of other states Group three is $700.00 (AZ, CA) - AZ borders CA Smells like a hierarchical query, but I'm not sure. Also need to be able to assign a group number / designation to the individual records. Anyone dealt with this before? -- [EMAIL PROTECTED] www.mymacaronilife.com [excessive quoting removed by server] _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://leafe.com/mailman/listinfo/profox OT-free version of this list: http://leafe.com/mailman/listinfo/profoxtech ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
