Zusätzliche Informationen

I tested your case against the numeric "numb" field and a calculated text field "testnumb" and neither returns the null record. Detailed documentation on this can be found here: https://technet.microsoft.com/en-us/library/ms191270(v=sql.105).aspx. Essentially, NULL is not the same as blank, empty, or zero. It is an "unknown". Because it is of "unknown" value, our definition queries and selections will not return the value. To return the selection you desire, the correct query is: SELECT * FROM test1 WHERE numb <>1 OR numb IS NULL.
