How can I define a column in the table as read-only? I have some "computed by" columns, e.g.: consumedvalue computed by (quantity*unitprice)
These columns can not be updated, otherwise I get the following exception: ProgrammingError: (ProgrammingError) (-151, 'isc_dsql_prepare: \n attempted update of read-only column') Werner --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
