I've got a DBGrid in which several titles are listed with their media (CD,LP,MC). I've made the Datasource of the grid a Query,because the titles are linked to a media DBFile using a Media_ID field. (I wanted the name of the medium appear in the GRID rather than the ID,so I thought I had to use a Query here). But updating a record is now causing a problem,because the Query is readonly. Is there a standard solution for this sort of problem?
