Help for stored procedure and Null...

Hi,
I have write a stored procedure which makes update in a numeric (int) field.

Depending on data in other table, in some case the result of query get a
Null value instead a zero value...

How can I tell to Update query to NOT update field if the value is Null ?

I hope my word clear...

here the stored procedure:

UPDATE dbo.ANAUTENTI

SET dist1punti = dist1punti +

(SELECT SUM(TEMPIMPORTAZIONEDIST1.qnt * ANAARTICOLI.punti) AS totalepunti

FROM TEMPIMPORTAZIONEDIST1 INNER JOIN

ANAARTICOLI ON TEMPIMPORTAZIONEDIST1.codicearticolo =
ANAARTICOLI.codartdist1

WHERE (TEMPIMPORTAZIONEDIST1.piva = ANAUTENTI.piva))

WHERE (piva IN

(SELECT piva

FROM TEMPIMPORTAZIONEDIST1

GROUP BY piva))

Thanks in advance

UPDATE tbl
SET col = col + coalesce((SELECT ...), 0)
The coalesce function takes list of arguments and returns the first non-NULL
value in the list, or NULL if all values are NULL.
