Which schema? The internal SQL schema (which version 9? 10?) or the ODBC schema? They are not the same.
Internal schema is documented via the Show Data Structure menu command.
ODBC schema can be figured out by linking all tables and studying them.
Not really much documentation in this area.
For the internal database, the names are ZONECATEGORIES.NAME and ZONES.NAME so I assume you're talking about the ODBC schema...
Please give complete info in your questions - version of AC, platform, etc....
