Hello all,

I have a doubt. In the next example, I have a table with two columns:
- DATE
- MONEY

And a VIEW which SUM's the money GROUPing by 'month/year' (I cut off the day)...

Ok.. I would like to be able to SELECT * FROM VIEW.. but restricting by complete dates (dd/mm/yyyy)... (Last select in the example)

I think it isn't possible, but I would like to know your opinion... Or if there is any workaround...

Best regards..

--==============================
DROP TABLE ty_test;
CREATE TABLE ty_test
(datein date NOT NULL,
money numeric(6,2) NOT NULL,
PRIMARY KEY (datein)
) WITHOUT OIDS;

INSERT INTO ty_test VALUES ('2002/10/01',10);
INSERT INTO ty_test VALUES ('2002/10/15',20);
INSERT INTO ty_test VALUES ('2002/11/15',30);

DROP VIEW vw_ty_test;
CREATE VIEW vw_ty_test AS
SELECT
TO_CHAR(datein,'MM/YYYY') AS datein2,
SUM(money)
FROM
ty_test
GROUP BY
datein2;

SELECT * FROM ty_test; -- All rows from table.
SELECT * FROM vw_ty_test; -- All rows from view.

SELECT * FROM vw_ty_test WHERE datein BETWEEN '2002/10/01' AND '2002/10/9';
