Hello all,
how can I adjust this query to perform this Update?

UPDATE SD
SET SbilPiu = SUM(RdP.SbilCond)
FROM app.T_SbilDelta SD
INNER JOIN app.T_RdPOrario RdP
ON rdp.RdPOrarioTestata_ID = sd.RapportoDiProduzioneTestata_ID
WHERE rdp.SbilCond > 0 AND sd.RapportoDiProduzioneTestata_ID = 37

In this way it returns me this error:


An aggregate may not appear in the set list of an UPDATE statement.

Thanks in advance.

Luigi

update T_SbilDelta
set SbilPiu = (select sum(SbilCond) from T_RdPOrario where RapportoDiProduzioneTestata_ID = 37)
where RapportoDiProduzioneTestata_ID = 37

make it generic to do update for all ID values in one shot

update d
set d.SbilPiu = o.Total
FROM  T_SbilDelta  d
INNER JOIN (select RapportoDiProduzioneTestata_ID,sum(SbilCond) AS Total
            from T_RdPOrario 
            group by RapportoDiProduzioneTestata_ID)o
ON o.RapportoDiProduzioneTestata_ID = d.RapportoDiProduzioneTestata_ID

Could also use a cte
;WITH cte AS 
(select RapportoDiProduzioneTestata_ID,sum(SbilCond) AS Total
            from T_RdPOrario 
            group by RapportoDiProduzioneTestata_ID)
update d
set d.SbilPiu = o.Total
FROM  T_SbilDelta  d
INNER JOIN cte o
ON o.RapportoDiProduzioneTestata_ID = d.RapportoDiProduzioneTestata_ID

You may need to add the other condition in the original query:


UPDATE dbo.T_SbilDelta 
SET 
    SbilPiu = (SELECT SUM(SbilCond) FROM dbo.T_RdPOrario 
        ... WHERE ... AND SbilCond > 0)
WHERE RapportoDiProduzioneTestata_ID = ...
