about primary key
-
whenever we establish connection to database through "coding" we have to generate set of the objects properties for "update","delete"and "insert" commands.But before that we have to initialize and set the primary key.my question is why we set the primary key by coding? because primary key is set while creating a database itself.so what is the need of set again?
coding makes me interesting in dot net

i think here you are setting primary key for dataset tables bcz this tables will be updated as it is into database so we need same structure
