How to sum multiple rows with specific criteria in SQL

Question

I have a query to sum balances by Product below:

SELECT BCM_CORPORATION_NUMBER, BCM_PRODUCT
  SUM(BCM_TOT_NEW_BAL) AS TOTAL_BALANCE
FROM BCM_IN
GROUP BY BCM_CORPORATION_NUMBER, BCM_PRODUCT
ORDER BY BCM_CORPORATION_NUMBER ASC;

Results :

Corp.        PRODUCT.    TOTAL_BALANCE
002030.      VCLBUS.       3000
002030.      VGOBUS.       1000
002030.      VCL000.       4000

I want to combine the totals for Products VCLBUS & VGOBUS to display a total of 4000 together without the VCL000 product.

To look like this: Corp. PRODUCT. TOTAL_BALANCE 002030. VCLBUS/VGOBUS. 4000 002030. VCL000. 4000

Answer 1

Is this what you want?

SELECT BCM_CORPORATION_NUMBER, SUM(BCM_TOT_NEW_BAL) AS TOTAL_BALANCE
FROM BCM_IN
WHERE BCM_PRODUCT IN ('VCLBUS', 'VGOBUS')
GROUP BY BCM_CORPORATION_NUMBER
ORDER BY BCM_CORPORATION_NUMBER ASC;

Or you may what:

WHERE BCM_PRODUCT <> 'VCL000'

Answer 2

Here's your query.

SELECT t1.BCM_CORPORATION_NUMBER, t1.BCM_PRODUCT, SUM(t1.TOTAL_BALANCE) 
FROM (SELECT BCM_CORPORATION_NUMBER, BCM_PRODUCT
     SUM(BCM_TOT_NEW_BAL) AS TOTAL_BALANCE, 
     FROM BCM_IN
     GROUP BY BCM_CORPORATION_NUMBER, BCM_PRODUCT
     ) t1
WHERE t1.BCM_PRODUCT IN ('VCLBUS', 'VGOBUS')
ORDER BY t1.BCM_CORPORATION_NUMBER ASC

or

SELECT BCM_CORPORATION_NUMBER
    , BCM_PRODUCT
    , BCM_TOT_NEW_BAL
    , SUM(BCM_TOT_NEW_BAL) AS TOTAL_BALANCE
FROM BCM_IN
WHERE BCM_PRODUCT IN ('VCLBUS', 'VGOBUS')
GROUP BY BCM_CORPORATION_NUMBER, BCM_PRODUCT, BCM_TOT_NEW_BAL
ORDER BY BCM_CORPORATION_NUMBER ASC;

Answer 3

Suppose your Output is in Temp table or CTE

create table #Output(Corp varchar(15),PRODUCT varchar(50),TOTAL_BALANCE int)



insert into #Output 
SELECT BCM_CORPORATION_NUMBER, BCM_PRODUCT
  SUM(BCM_TOT_NEW_BAL) AS TOTAL_BALANCE
FROM BCM_IN
GROUP BY BCM_CORPORATION_NUMBER, BCM_PRODUCT
;

OR

;With OutPutCTE
(
SELECT BCM_CORPORATION_NUMBER, BCM_PRODUCT
  SUM(BCM_TOT_NEW_BAL) AS TOTAL_BALANCE
FROM BCM_IN
GROUP BY BCM_CORPORATION_NUMBER, BCM_PRODUCT
--ORDER BY BCM_CORPORATION_NUMBER ASC
)

Suppose, like you want to group 'VCLBUS', 'VGOBUS' Similarly you will want to Sum GROUP other Product and SUM them accordingly.

Create #temp table and store product according to their group

create table #GroupType(PRODUCT varchar(50),groupid int)
insert into #GroupType values
 ('VCLBUS.',1)
,('VGOBUS.',1)
,('VCL000.',2)

select o.* 
,sum(TOTAL_BALANCE)over(partition by g.groupid )Group_TOTAL_BALANCE 
from #Output O
inner join #GroupType G on o.PRODUCT=g.PRODUCT

I think you can get the whatever output you want.
