Hello Friends,

I have a doubt regarding balance sheet calculation in my Software. I am using a stored procedure for these calculations. I have some commands for calculation as given below:

/******************************************************************/
DECLARE @car_req FLOAT
DECLARE @amt_gen FLOAT
DECLARE @amt_shp FLOAT
DECLARE @amt_sho FLOAT
DECLARE @bal_gen FLOAT
DECLARE @bal_shp FLOAT
DECLARE @bal_sho FLOAT
DECLARE @tab_id INT

CREATE TABLE #Temp
(
rec_id INT IDENTITY NOT NULL
, cargo_required FLOAT
, amount_general FLOAT
, amount_ship FLOAT
, amount_shore FLOAT
, balance_general FLOAT
, balance_ship FLOAT
, balance_shore FLOAT
)

INSERT INTO #Temp (cargo_required, amount_general, amount_ship, amount_shore)
SELECT 5000, 1500, 1450, 1490
UNION ALL
SELECT 0, 3500, 3500, 3500
UNION ALL
SELECT 7000, 4500, 4550, 4560
UNION ALL
SELECT 0, 2500, 2000, 2000

DECLARE temp_cursor CURSOR FAST_FORWARD FOR
SELECT rec_id, cargo_required, amount_general, amount_ship, amount_shore
FROM #Temp

OPEN temp_cursor

FETCH NEXT FROM temp_cursor
INTO @tab_id, @car_req, @amt_gen, @amt_shp, @amt_sho

WHILE @@FETCH_STATUS = 0
BEGIN
IF (@car_req > 0)
BEGIN
UPDATE #Temp
SET balance_general = @car_req - amount_general
, balance_ship = @car_req - amount_ship
, balance_shore = @car_req - amount_shore
WHERE rec_id = @tab_id
END
ELSE
BEGIN
UPDATE #Temp
SET balance_general = @bal_gen - amount_general
, balance_ship = @bal_shp - amount_ship
, balance_shore = @bal_sho - amount_shore
WHERE rec_id = @tab_id
END

SELECT @bal_gen = balance_general, @bal_shp = balance_ship, @bal_sho = balance_shore
FROM #Temp
WHERE rec_id = @tab_id

FETCH NEXT FROM temp_cursor
INTO @tab_id, @car_req, @amt_gen, @amt_shp, @amt_sho
END

SELECT * FROM #Temp

CLOSE temp_cursor
DEALLOCATE temp_cursor

DROP TABLE #Temp

/***************************************************************/

This is what acutally I am having in my stored procedure except the temporary table. The values which I am inserting here will get from my actual tables. What I need is to calculate balance. If you run this script you can see how the balance is calculating using the cursor.

I want an efficient way to calculate the same. I know cursor is not at all good option in stored procedures. Do you have any Idea to make this script in an efficient and simple way?

Thanks and Regards
Boney

Here is one of method using WHILE loop instead of cursor

DECLARE @bal_gen FLOAT
DECLARE @bal_shp FLOAT
DECLARE @bal_sho FLOAT
DECLARE @tab_id INT

CREATE TABLE #Temp
(
rec_id INT IDENTITY NOT NULL
, cargo_required FLOAT
, amount_general FLOAT
, amount_ship FLOAT
, amount_shore FLOAT
, balance_general FLOAT
, balance_ship FLOAT
, balance_shore FLOAT
)

INSERT INTO #Temp (cargo_required, amount_general, amount_ship, amount_shore)
SELECT 5000, 1500, 1450, 1490
UNION ALL
SELECT 0, 3500, 3500, 3500
UNION ALL
SELECT 7000, 4500, 4550, 4560
UNION ALL
SELECT 0, 2500, 2000, 2000



SELECT @bal_gen=0,@bal_shp=0,@bal_sho=0
SELECT @tab_id=MIN(rec_id)
FROM #Temp

WHILE @tab_id IS NOT NULL
BEGIN
UPDATE #Temp
SET @bal_gen=balance_general =CASE WHEN  cargo_required > 0 THEN cargo_required ELSE @bal_gen END - amount_general
, @bal_shp=balance_ship = CASE WHEN  cargo_required > 0 THEN cargo_required ELSE @bal_shp END  - amount_ship
, @bal_sho=balance_shore = CASE WHEN  cargo_required > 0 THEN cargo_required ELSE @bal_sho END  - amount_shore
WHERE rec_id = @tab_id

SELECT @tab_id=MIN(rec_id)
FROM #Temp
WHERE rec_id >@tab_id
END

Select * FROM #Temp

Thank you so much Visakh. It's really a nice way. While loop is far better than cursor. But one more doubt, do we have any way to make this without using any loop method.

I am going to use user method.

Once again Thank You So Much.

Thanks and Regards
