Vincent,
can I just check that I'm on the right wavelength here. I'm looking at
generating a method like (well, I have already done this much):
public test.interfaces.AccountData loadData(java.sql.ResultSet rs)
throws java.sql.SQLException
{
test.interfaces.AccountData data = new
test.interfaces.AccountData();
data.balance = rs.getFloat("balance");
data.id = rs.getInt("id");
data.owner = rs.getCustomer("owner");
return data;
}
and you can obviously see my problem... what to do with
customer... anyway, I will look at the easy part now whilst thinking about
it. another question before I go... what should these methods be
called? queryByXXX()?
cheers
