oops I just found a mistake in the query...

    SELECT A1.oid, A1.concepte, A1.deure, A1.haver,
           sum( COALESCE( A2.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
     WHERE A1.numero=11189
  GROUP BY A1.oid, A1.concepte, A1.deure, A1.haver
  ORDER BY A1.oid;
