This Exeption may rise when trying to Fill a table using a Table adapter.
One of the reasons this may happen is if the SQL statement is not Selecting a column that is not null in the DB
for example :
if table has field1, field2, field3 and all do not allow null, This exception will be thrown if you try SELECT field1, field2 from Table.
Of course, there may be other reasons for the excption like actually violating a constraint 🙂
