This is only a comment and not needed ^

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 -- change "<=" to ">="
AND A1.numero = A2.numero
WHERE A1.numero=11189
GROUP BY A1.oid, A1.concepte, A1.deure, A1.haver
ORDER BY A1.oid;
