Question

I have a situation where i need to access different rows of result set via JDBC. I’m new to it.

As seen from picture i need shutoff_valve value as 43 in some variable in my java code. Similarly how to access other node_type values.

Thanks

Answer 1

Something like this:

        ps = con.prepareStatement(yourSqlHere);
        // optional parameters setting
        ps.setXXX(1, val);
        ResultSet rs = ps.executeQuery();
        while (rs.next()) {
            System.out.println(rs.getString("NODE_TYPE") + ": " + rs.getInt("TOTAL"));
        }

Actually, good introduction to low-level JDBC contained in JDK.
