Hi, I have a master/detail relationship between 2 queries in a datasnap application. Is it possible to insert new records into the detail when a new record has been inserted into the master, before the whole data is committed to the DB? I'd like to be able to do this on the server side. I know that I should be doing this on the OnUpdateData or OnBeforeUpdateRecord of the export dataset provider on the server, but what is the exact syntax to use? When I tried adding new records to the detail data packet, I kept getting an 'operation not supported' exception of some sort. Tks - Adrian.
