P.S. I viewed the result set in SQL Server and saw that one of the columns I specified for use in a unique index for VDF unexpectedly had null values. I applied the isNull function to that and the nulls now show as zeros. But this did not resolve the error message. VDF can connect to the table, but cannot find or display any data.

I've always been under the impression that the CK and DF/VDF can handle nulls just fine so long as columns used in index segments are set to "not null".

Is this no longer true?
