How to display rows that when added together equal zero

Question

Been searching for a few weeks for a solution to this but have come up blank.

I have table of data similar to this:

client_ref  supplier_key  client_amou         


        

Answer 1

Try this instead:

SELECT t1.*
FROM transactions AS t1
INNER JOIN
(
  SELECT
    tbis.client_ref ,
    tbis.supplier_key,
    sum(tbis.client_amount) AS total
  FROM transactions tbis 
  WHERE tbis.client_amount !=0 
  GROUP BY tbis.client_ref, tbis.supplier_key 
  HAVING sum(tbis.client_amount) =0 
) AS t2  ON t1.client_ref = t2.client_ref
        AND t1.supplier_key = t2.supplier_key
ORDER BY t2.total;

SELECT 
    * 
FROM 
    tbis
INNER JOIN
(
    SELECT
        client_ref, supplier_key
    FROM
        tbis
    GROUP by client_ref, supplier_key
    HAVING sum(client_amount) = 0
) match
ON match.client_ref = tbis.client_ref 
AND match.supplier_key = tbis.supplier_key

Answer 3

SELECT t.* FROM Table1 AS t INNER JOIN
(SELECT [client_ref], [supplier_key], SUM([client_amount]) as Total
FROM Table1 GROUP BY [client_ref], [supplier_key]) AS sumTable
ON t.[client_ref] = sumTable.[client_ref] AND
t.[supplier_key] = sumTable.[supplier_key]
WHERE Total = 0;

Answer 4

One possible approach is to use the SUM() windowing function:

SELECT * 
FROM
( SELECT tbis.client_ref ,tbis.supplier_key,tbis.client_amount,
  SUM(tbis.client_amount) OVER (
    PARTITION BY tbis.client_ref, tbis.supplier_key) AS total_client_amount
  FROM [XXXX].[dbo].[transaction] tbis 
  WHERE tbis.client_amount !=0 
)
WHERE total_client_amount = 0

Answer 5

Make a new query for the data you want and join it by inner join to the query that produces the sums to restrict it to the lines you want.

Answer 6

SELECT client_ref ,supplier_key ,sum(client_amount) 
FROM   transaction
WHERE  client_amount <> 0 
GROUP BY client_ref, supplier_key 
HAVING sum(client_amount) = 0
