ok, se here is the table details:

-- Table: assentaments

-- DROP TABLE assentaments;

CREATE TABLE assentaments
(
  numero bigint NOT NULL,
  data date NOT NULL,
  concepte character varying NOT NULL,
  deure numeric(12,2) NOT NULL,
  haver numeric(12,2) NOT NULL,
  clau_compte character(13) NOT NULL,
  anys smallint NOT NULL,
  tipus smallint NOT NULL,
  ordre character(50) NOT NULL
) 
WITH OIDS;
ALTER TABLE assentaments OWNER TO postgres;


-- Index: anys

-- DROP INDEX anys;

CREATE INDEX anys
  ON assentaments
  USING btree
  (anys);

-- Index: clau_compte

-- DROP INDEX clau_compte;

CREATE INDEX clau_compte
  ON assentaments
  USING btree
  (clau_compte);

-- Index: data

-- DROP INDEX data;

CREATE INDEX data
  ON assentaments
  USING btree
  (data);

-- Index: numero

-- DROP INDEX numero;

CREATE INDEX numero
  ON assentaments
  USING btree
  (numero);




And here comes the SQL statement:

SELECT oid, concepte, deure, haver,
       delta_sum + ( SELECT SUM( COALESCE( A3.deure ) - COALESCE ( A3.haver ) )
                       FROM Assentaments A3
                      WHERE A3.clau_compte = '0257000000002'
                        AND A1.data BETWEEN '2006-01-01' AND '2006-06-30' ) AS starting_Sum
  FROM( 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.clau_compte = '0257000000002'
      GROUP BY A1.oid, A1.concepte, A1.deure, A1.haver
      ORDER BY A1.oid ) AS Summed_Assentaments( oid, concepte, deure, haver, delta_sum );


and here comes the error:

ERROR: missing FROM-clause entry in subquery for table "a1"
estat SQL: 42P01
Caràcter: 254


I can send you in a private e-mail some rows in .txt if you want to try ...

And no, there's no relation between numero and compte in my table, I used numero because for me it was easier to use only one field that use one with to options, data and between, but the code should look like it's now.

Sorry for the inconvenience ...



thanks again !
