Joel this work fine with insertcommand and updatecommand as long you open the connection prior to using the dataadapter, remember that the dataadapter will open and close the the connection in case it wasn't open at prior.
Now this will work for fields missing on the insert/update command, will not work if you put a null value on that field, or fiel.ds that you didn't set the value.
What I do in that case is that I have a method that goes over each row and col and sets default values or blank ones in case no default value exist.
