hi.. i have a table like this

1. Chart of account table
Account	Description	   Parent
1 ASSETS 0
101 CURRENT ASSETS 1
10100 Cash and Bank 101
10101 Petty Cash 10100
10301 Cash on Hand 10100
10501 Bank 10100
10701 Time Deposit 10100

2. Transaction table (only child account)
Account   GroupID    BankID    Amount
10101 2 1 10
10101 2 2 20
10301 2 1 10
10501 2 1 10
10501 2 2 20
10701 2 2 30

I need the output seems like this:
Account  GroupID     BankID   SumAmount
1 2 1 30
1 2 2 70
101 2 1 30
101 2 2 70
10100 2 1 30
10100 2 2 70
10101 2 1 10
10101 2 2 20
10301 2 1 10
10501 2 1 10
10501 2 2 20
10701 2 2 30

So, it's populated sum within GroupID & BankID for each parents of account.

Can u pls give me the CTE recursion query ?

Thanks

Quick question, what SQL Server version are you on?

If you're going to be doing a fair bit of reporting on hierarchical structures, please consider the following article. It takes a bit to setup but, once in place, is very quick and offers several different methods to analyze hierarchical structures.

--Jeff Moden
"RBAR is pronounced "ree-bar" and is a "Modenism" for "Row-By-Agonizing-Row".

First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column."

(play on words) "Just because you CAN do something in T-SQL, doesn't mean you SHOULDN'T." --22 Aug 2013

Here is an alternative method without recursion, uses Tally table type looping instead. The code uses Chris's sample data to produce comparable output. It is simplified and limited to that data set, not meant as a full solution but rather as a demonstration of the method.


USE tempdb;
GO
-- create sample data
CREATE TABLE #ChartOfAccount (Account INT, [Description] VARCHAR(30), Parent INT)
INSERT INTO #ChartOfAccount (Account, [Description], Parent)
SELECT 1, 'ASSETS', 0 UNION ALL
SELECT 101, 'CURRENT ASSETS', 1 UNION ALL
SELECT 10100, 'Cash and Bank', 101 UNION ALL
SELECT 10101, 'Petty Cash', 10100 UNION ALL
SELECT 10301, 'Cash on Hand', 10100 UNION ALL
SELECT 10501, 'Bank', 10100 UNION ALL
SELECT 10701, 'Time Deposit', 10100;

CREATE TABLE #Transaction (Account INT, GroupID INT, BankID INT, Amount INT) -- (only child account)
INSERT INTO #Transaction (Account, GroupID, BankID, Amount)
SELECT 10101, 2, 1, 10 UNION ALL
SELECT 10101, 2, 2, 20 UNION ALL
SELECT 10301, 2, 1, 10 UNION ALL
SELECT 10501, 2, 1, 10 UNION ALL
SELECT 10501, 2, 2, 20 UNION ALL
SELECT 10701, 2, 2, 30;

/* CTE ACCOUNT_UPLINE
Creates one row for each node in the account's upline.
Note: simplified method using integer division and
a pseudo Tally table
*/
;WITH ACCOUNT_UPLINE AS
(
SELECT
X.Account
,X.UPLINE_PART
FROM
(
SELECT
COA.Account
,COA.Parent
,X.N
,CASE
WHEN X.N = -2 THEN COA.Account
WHEN POWER(10,X.N) = 0 THEN COA.Parent
ELSE COA.Parent / POWER(10,X.N)
END AS UPLINE_PART
FROM #ChartOfAccount COA
CROSS APPLY
(SELECT N FROM (VALUES (-2),(-1),(2),(4),(5),(6),(7)) AS X(N)) AS X
) AS X
WHERE X.UPLINE_PART > 0
OR ( X.Parent = 0 AND X.N = 1)
)
/* CTE FINAL_SET
Window function aggregation and grouping
*/
,FINAL_SET AS
(
SELECT
AU.UPLINE_PART AS Account
,TR.GroupID
,TR.BankID
,ROW_NUMBER() OVER
(
PARTITION BY TR.GroupID,TR.BankID,AU.UPLINE_PART
ORDER BY (SELECT NULL)
) AS GR_RID
,SUM(TR.Amount) OVER
(
PARTITION BY TR.GroupID,TR.BankID,AU.UPLINE_PART
) AS Amount
FROM #Transaction TR
INNER JOIN ACCOUNT_UPLINE AU
ON TR.Account = AU.Account
)
SELECT
FS.Account
,FS.GroupID
,FS.BankID
,FS.Amount
FROM FINAL_SET FS
WHERE FS.GR_RID = 1
ORDER BY FS.Account,FS.GroupID,FS.BankID;

DROP TABLE #ChartOfAccount
DROP TABLE #Transaction

Account  GroupID  BankID  Amount
-------- -------- ------- -------
