Hello all,
I'm trying this Update:

UPDATE SD
SET SbilOnerPiu = (SELECT ISNULL(SUM(RO.SbilOner),0)
FROM app.T_SbilDelta SD
INNER JOIN app.T_RdPOrario RO
ON SD.RapportoDiProduzioneTestata_ID = RO.RdPOrarioTestata_ID
WHERE SD.RapportoDiProduzioneTestata_ID = @RdPOrarioTestataID
AND SD.TipoAbilitazione_ID = 7 AND RO.SbilOner >= 0);

but I'm getting the error:

Invalid object name 'SD'.

What's wrong with this?

The Khtan's solution works well, thank you very much.
So I need to have the SUM aggregation in a subquery.

this can still return NULL if you dont have any matching records returned by subquery

ok.. otherwise you've wrap the subquery around ISNULL or COALESCE to convert them to some constant value
