    First of all, if a table doesn't have a key. It's not really a table. Is there any kind of documentation that can give you a hint as to what this thing means? The only table anywhere close to t this was for a medical test. They were keyed on patient identifiers and followed by over 100 allergy test results. It was pretty easy to see what the key had to be.

    Please post DDL and follow ANSI/ISO standards when asking for help.
