Updating of ADO.NET/2.0

[farmer]

Yes we all know OleDbDataAdapter.Update(DataTable) call update
Database,but what else for DataTable.AcceptChanges()? When/why we have
to use it?

 

[Bruce Barker]

datatables track changes (adds, updates and deletes). unlike com ado,
datasets have no methods for reading, writing or updating databases. this is
performed by external object (like a dataadapter). thus it has no way of
knowing when your code is done with this tracking info. when you call
AcceptChanges(), it resets all the change tracking info.
