Crystal Reports Select-Anweisung Hilfe

Question

Ich versuche, die MV_AgeBased und die MV_FeeInLieu Spalten hinzufügen, jedoch einige der Spalten möglicherweise Null oder leer in der db, dies führt zu Nullen zurück für die CodeEntity. Irgendwelche Vorschläge?

 SELECT "AuditorYearEnd"."PP_MH_Pri", "AuditorYearEnd"."PP_MH_Other", 
"County"."Name", "AuditorYearEnd"."TOTAL_Personal_calc", 
"AuditorYearEnd"."PP_BusPersonal", "AuditorYearEnd"."TaxYr", 
"AuditorYearEnd"."CodeEntity", "AuditorYearEnd"."MV_AgeBased", 
"AuditorYearEnd"."MV_FeeInLieu" 
    FROM "txctr"."dbo"."AuditorYearEnd" "AuditorYearEnd" 
INNER JOIN "txctr"."dbo"."County" "County" ON "AuditorYearEnd"."CodeCounty"="County"."CodeCounty" 
    WHERE "AuditorYearEnd"."TaxYr"=2010 AND "AuditorYearEnd"."CodeEntity"='1010'

SELECT "AuditorYearEnd"."PP_MH_Pri", "AuditorYearEnd"."PP_MH_Other", 
"County"."Name", "AuditorYearEnd"."TOTAL_Personal_calc", 
"AuditorYearEnd"."PP_BusPersonal", "AuditorYearEnd"."TaxYr", 
"AuditorYearEnd"."CodeEntity", "AuditorYearEnd"."MV_AgeBased", 
"AuditorYearEnd"."MV_FeeInLieu" 
FROM ("txctr"."dbo"."AuditorYearEnd" "AuditorYearEnd" 
INNER JOIN "txctr"."dbo"."County" "County" ON "AuditorYearEnd"."CodeCounty"="County"."CodeCounty" 
WHERE "AuditorYearEnd"."TaxYr"=2010 AND "AuditorYearEnd"."CodeEntity"='1010') 

Add für alle potenziell null Spalten "WHERE [Spalte] nicht null ist"?

Nicht absolut sicher, was hier gefragt wird.
