An OraField object is accessed indirectly by retrieving a field from the OraFields collection of an OraDynaset object.
If the current row is being updated, then the OraField object represents the currently updated value, although the value may not yet have been committed to the database.
Assignment to the Value property of a field is permitted only if a record is being edited (using the Edit method) or a new record is being added (using the AddNew method). Other attempts to assign data to the Value property of a field results in an error.
