extract Update Values
Extracts the value of the public, mutable properties of a data class in the order in which they are declared in the primary constructor not including the fields designated as being within the primary key. We assume that the values returned correspond to data that must be used to update a record within the database table. Thus, we assume that the user will not update the values of the fields within the primary key. The returned values are in the order of the properties listed in the DbTableData class, not including the primary key fields.
If the object is not an instance of a data class, then the returned list will be empty.
