Would it work to create a virtual (calculated) field that's used instead of the CLOB field? Would I need to list the fields in the table's SQL property rather than "select *"?

At program load time, I can display nothing. But once the program has started up, the calc field can explicitly load from the CLOB field.

But what happens if I want to update the value of the CLOB field? How does a calc field deal with that?
