The inner query returns more than 1 row and for each row the value has to be updated in the outer query.

Currently the query is updating only for the 1st row returned by the inner query.

How to achieve this?

UPDATE FloatBal
SET FloatBal.AvlBalance =
case when AllLoads.LoadType like '%Credit'
then (FloatBal.AvlBalance - LoadBal.TotalLoadAmt)
when AllLoads.LoadType like '%Debit'
then (FloatBal.AvlBalance + LoadBal.TotalLoadAmt)
END

FROM dbo.[EPP_Fin_FloatBalance] FloatBal
INNER JOIN
(SELECT AllLoad.CardProduct,sum(LoadAmt) AS TotalLoadAmt,allload.LoadType
FROM [AllLoads] AllLoad
LEFT JOIN dbo.EPP_Fin_FloatBalance_Log FloatBalLog
ON FloatBalLog.ID = AllLoad.ID
AND FloatBalLog.CardProduct = AllLoad.CardProduct
WHERE FloatBalLog.ID IS NULL
AND AllLoad.CardProduct IN ('FP51')
AND AllLoad.LoadType = 'OBI BalAdjust Debit'
GROUP BY AllLoad.CardProduct,AllLoad.LoadType
) LoadBal

ON LoadBal.[CardProduct] = FloatBal.[ProductCode]COLLATE Latin1_General_CI_AI
WHERE FloatBal.ProductCode COLLATE Latin1_General_CI_AI IN ('FP51')

do you mean you've more than one row per CardProduct in dbo.[EPP_Fin_FloatBalance] table? probably you can post some sample data to illustrate the scenario and somebody will be able to help you out

The inner query

SELECT AllLoad.CardProduct,sum(LoadAmt) AS TotalLoadAmt,allload.LoadType
FROM [AllLoads] AllLoad
LEFT JOIN dbo.EPP_Fin_FloatBalance_Log FloatBalLog
ON FloatBalLog.ID = AllLoad.ID
AND FloatBalLog.CardProduct = AllLoad.CardProduct
WHERE FloatBalLog.ID IS NULL
AND AllLoad.CardProduct IN ('FP51')
AND AllLoad.LoadType = 'OBI BalAdjust Debit'
GROUP BY AllLoad.CardProduct,AllLoad.LoadType

would return the rows

CardProduct TotalLoadAmt LoadType
FP51 50.00 OBI BalAdjust Credit
FP51 25.00 OBI BalAdjust Debit

The dbo.[EPP_Fin_FloatBalance] has one row per card product

AvlBalance CurrencyCode ProductCode
110.00 GBP FP51

So after the update query the avlBalance in dbo.[EPP_Fin_FloatBalance] should be 85.

Thanks,

This?

UPDATE FloatBal
SET FloatBal.AvlBalance = FloatBal.AvlBalance + LoadBal.TotalLoadAmt

FROM dbo.[EPP_Fin_FloatBalance] FloatBal
INNER JOIN 
(
	SELECT 
	AllLoad.CardProduct,
	sum(case when AllLoads.LoadType like '%Credit' then LoadAmt * -1 else LoadAmt end) AS TotalLoadAmt,
	allload.LoadType
	FROM [AllLoads] AllLoad
	LEFT JOIN dbo.EPP_Fin_FloatBalance_Log FloatBalLog
	ON FloatBalLog.ID = AllLoad.ID
	AND FloatBalLog.CardProduct = AllLoad.CardProduct 
	WHERE FloatBalLog.ID IS NULL
	AND AllLoad.CardProduct IN ('FP51')
	AND AllLoad.LoadType = 'OBI BalAdjust Debit'
	GROUP BY AllLoad.CardProduct,AllLoad.LoadType
)LoadBal


ON LoadBal.[CardProduct] = FloatBal.[ProductCode]COLLATE Latin1_General_CI_AI
WHERE FloatBal.ProductCode COLLATE Latin1_General_CI_AI IN ('FP51')

No, you're never too old to Yak'n'Roll if you're too young to die.
