Do worry, we are gett closer to a working query. Each round trip is providing more details that
will help us to craft a better query:
SELECT A1.oid, A1.concepte, A1.deure, A1.haver,
sum( COALESCE( A1.deure, 0 ) -
COALESCE( A2.haver, 0 )) AS value_sum
FROM Assentaments AS A1
INNER JOIN Assentaments AS A2
ON A1.oid <= A2.oid
AND A1.numero = A2.numero --this should only preform a sum on a specify numero
WHERE A1.numero=11189
GROUP BY A1.oid, A1.concepte, A1.deure, A1.haver
ORDER BY A1.oid;
