Subj:   Empty Value
 
From:   Hassinger, Bill

This is probably something simple, but my mind is drawing a blank:

When I run the following query:

        select uncleharryind, count(*)
                from t1
                where uncleharryind IS NOT NULL
                group by 1

I get the following results:

        UncleHarryInd   Count(*)
        Y                287584
                       16404798
                        5704732

The Y is obvious, the 5 million values are blanks, what are the other 16.5 million values? A query to select NULLS returns no rows. I thought TD was ASCII? What other value could load and not be visable. Uncleharryind is defined as CHAR(1).
