Check the below input data and expected output to prepare the report on bank account transaction like generate the data of AccountBalance column where for CR plus the transaction value and for DR minus the transaction value.

Input Data:

TransactionDate AccName    Type Amount
--------------- ---------- ---- -------------
2017-01-01      Anvesh     CR   60000.00
2017-02-01      Anvesh     DB   8000.00
2017-03-01      Anvesh     CR   8000.00
2017-04-01      Anvesh     DB   5000.00
2017-01-01      Nupur      CR   10000.00
2017-02-02      Nupur      CR   8000.00
2017-03-03      Nupur      DB   8000.00

Expected Output:

TransactionDate AccName    Type Amount                AccountBalance
--------------- ---------- ---- --------------------- ---------------
2017-01-01      Anvesh     CR   60000.00              60000.00
2017-02-01      Anvesh     DB   8000.00               52000.00
2017-03-01      Anvesh     CR   8000.00               60000.00
2017-04-01      Anvesh     DB   5000.00               55000.00
2017-01-01      Nupur      CR   10000.00              10000.00
2017-02-02      Nupur      CR   8000.00               18000.00
2017-03-03      Nupur      DB   8000.00               10000.00

Create a table with sample data:

CREATE TABLE AccountBalance
(
	TransactionDate DATE
	,AccName VARCHAR(10)
	,Type VARCHAR(2)
	,Amount MONEY
)
GO

INSERT INTO AccountBalance
VALUES
('2017-01-01','Anvesh','CR','60000')
,('2017-02-01','Anvesh','DB','8000')
,('2017-03-01','Anvesh','CR','8000')
,('2017-04-01','Anvesh','DB','5000')
,('2017-01-01','Nupur','CR','10000')
,('2017-02-02','Nupur','CR','8000')
,('2017-03-03','Nupur','DB','8000')
GO

Solution:

;WITH CTE AS
(
    SELECT TransactionDate , AccName , Type 
            , CASE WHEN Type = 'DB' THEN AMOUNT * -1 ELSE AMOUNT END Amount, Amount Amt
            ,ROW_NUMBER() OVER (PARTITION BY AccName ORDER BY (SELECT NULL)) rnk
    FROM AccountBalance
)
SELECT  TransactionDate , AccName , Type , Amt Amount
, (SELECT SUM(Amount) FROM CTE c2 WHERE c2.AccName = c1.AccName AND c2.rnk <= c1.rnk ) AccountBalance
FROM CTE c1
