Thanks
No i can't use views dirctly, because in the
framwork ervery class maps to one table.
But i found that i can call stored precedures.
Maybe i can call the view in a stored procedure ?
does postgres allow this ?
here is a small sniplet of the castor doc:
The is also a special form of query that
gives a possibility to call stored procedures:
oql = db.getOQLQuery( "CALL sp_something($) AS myapp.Product" );
Here sp_something is a stored procedure returning one or
more ResultSets with the same sequence of fields as Castor-generated
SELECT for the OQL query "SELECT p FROM myapp.Product p"
(for objects without relations the sequence is: identity, then all
other fields in the same order as in mapping.xml).

could you create a view and query that?
CREATE TABLE pers (fname);
INSERT INTO pers VALUES ('Joel');
CREATE VIEW pers_use_me AS SELECT fname, lower(fname) as lower_fname
FROM pers;
SELECT * FROM pers WHERE lower_fname = 'joel';
