This is exactly why the design of the tables is so important. It's really easy to add atomic fields together to get the required results. Much less easy to split them up. Don't store information together in a field if you need it separately.
That said, if the data follows certain rules then it can usually be manipulated. To help you manipulate the data we'd need, at the very least, a clear description of any rules you expect the data to follow.
