Обсуждение: Updateable ResultSet

hi,

I have a Java application that inserts data  (using jdbc) in the database with
methods similar to the ones below.

These methods function in MS Access 2000 and MySQL and now I am trying to
port this application to use PostgreSQL.

In PostgreSQL get the error "This resultSet is not updateable."

Any advice on how to solve this?

regards

      Connection con =
DriverManager.getConnection("jdbc:postgresql:kalle","kalle","");
        Statement stmt = con.createStatement();
        String sql = "create table koe (num int primary key,nimi
varchar(255))";
        int resu = stmt.executeUpdate(sql);

        sql = "insert into koe (num,nimi) values(1,'Kalle')";
        resu = stmt.executeUpdate(sql);
        sql = "select * from koe where num is null";
        ResultSet rs = stmt.executeQuery(sql);
       // above command functions OK
        rs.moveToInsertRow();
        rs.updateInt("num",2);
        rs.updateString("nimi","Rita");
        rs.insertRow();
        // above commands fail in postgreSQL but are OK in other databases

        stmt.close();
        con.close();

Only the dev driver supports updateable result sets

I tried to find a dev jdbc driver but I only seem to find this one that I am
using already:

http://www.ca.postgresql.org/ftpsite/binary/v7.2.1/RPMS/redhat-7.2/postgresql-jdbc-7.2.1-2PGDG.i386.rpm

Any advice on how to locate the dev driver?
