SQL-SERVER : Sub query for every row of the outer Select - sql

Question

Well i am creating a stored procedure in which i would like the sub-queries to be executed for each row of the outer select.
Every account has some payments and receipts that are stored in the same column.
For each account i would like to produce the sum of this column
The sub-queries create two columns PAYMENTS_SUM and RECEIPTS_SUM.The problem is that even if the summaries are produced they are executed only once.After some search i found out that this is the expected behavior.
But how can i produce these sums for each ACC.ACCOUNTID
BEGIN
SET NOCOUNT ON
SELECT DiSTINCT
ACC.ACCOUNT,
BM.CCY,
ACC.SEG,
(SELECT SUM(BM.ADJUSTMENT) AS PAYMENTS_SUM FROM [dbo].[Accounts] ACC
LEFT join [dbo].[BalanceMovements] BM ON BM.ACCOUNTID = ACC.ACCOUNTID collate database_default
WHERE
ACC.Account = ACC.ACCOUNT And
Month(BM.COB) = MONTH(GETDATE())
AND
YEAR(BM.COB) = YEAR(GETDATE())
AND
BM.ADJUSTMENT > 0
)
AS PAYMENTS_SUM,
(SELECT SUM(BM.ADJUSTMENT) AS PAYMENTS_SUM FROM [dbo].[Accounts] ACC
LEFT join [dbo].[BalanceMovements] BM ON BM.ACCOUNTID = ACC.ACCOUNTID collate database_default
WHERE
ACC.Account = ACC.ACCOUNT AND
Month(BM.COB) = MONTH(GETDATE())
AND
YEAR(BM.COB) = YEAR(GETDATE())
AND
BM.ADJUSTMENT < 0
)
AS RECEIPTS_SUM,
ACC.SystemAccount,
ACC.ENTITY,
ACC.BusinessGroup
FROM [dbo].[Accounts] ACC
LEFT join [dbo].[BalanceMovements] BM ON BM.ACCOUNTID = ACC.ACCOUNTID collate database_default
WHERE
Month(BM.COB) = MONTH(GETDATE())
AND
YEAR(BM.COB) = YEAR(GETDATE())
END
As you can see the result has the same value for each account.

Answer 1

This answer is a speculation, but hopefully gets closer to what you want. The idea is that you just want to conditionally aggregate the adjustment amount depending some various conditions. The other non aggregate columns are pretty much along for the ride, so we can just add them to GROUP BY clause.
SELECT
ACC.ACCOUNT,
BM.CCY,
ACC.SEG,
ACC.SystemAccount,
ACC.ENTITY,
ACC.BusinessGroup,
SUM(CASE WHEN BM.ADJUSTMENT > 0 THEN BM.ADJUSTMENT ELSE 0 END) AS PAYMENTS_SUM,
SUM(CASE WHEN BM.ADJUSTMENT <= 0 THEN BM.ADJUSTMENT ELSE 0 END) AS RECEIPTS_SUM
FROM [dbo].[Accounts] ACC
LEFT join [dbo].[BalanceMovements] BM
ON BM.ACCOUNTID = ACC.ACCOUNTID collate database_default
WHERE
MONTH(BM.COB) = MONTH(GETDATE()) AND YEAR(BM.COB) = YEAR(GETDATE())
GROUP BY
ACC.ACCOUNT,
BM.CCY,
ACC.SEG,
ACC.SystemAccount,
ACC.ENTITY,
ACC.BusinessGroup;
