You can test for NULL.
I recommend never using the Getxxx methods.

If DATE is a nullable field then you need to test for that condition in your reading code. If the request for that field gives an error then you need to find out why. In either case you need to examine the content of your database, and also use the debugger, to find out exactly what the situation is.

And for future reference, if code produces an error, then please tell us what it is; we cannot see your screen, or read your mind.
