Again, I don't understand what you mean.
In STANDARD.SELECTION you will see ALL the fields for each table.
If you want to see all fields of all tables you will need to check ONE table at a time.
Alliteratively, you can write a program in jBASE that will read the STANDARD.SELECTION and make some kind of output.
For SQL Server/Oracle there are always only 2 fields per table: ID + XML
