I think I've found a bug in how the jdbc driver (JDBC2) numbers the rows
in a result set. According to Sun's documentation for the ResultSet
interface, the rows in a result set should be numbered starting with
1. However, the ResultSet.java's first() routine set's current_row to
0. The odd thing is that beforeFirst() also sets current_row to 0, it
just does not load this_row. The bug manifests itself as such:
given ResultSet rs containing two rows:
rs.last();
System.out.println("Last id is: "+rs.getRow());
rs.first();
System.out.println("First id is: "+rs.getRow());
produces the output:
Last id is: 1
First id is: 0
I think the easiest fix would be to change getRow() so that it returns
current_row+1, and change beforeFirst so that it sets current_row to
-1. I'm not sure what other changes need to be made, but since the JDBC
driver does not allow one to refer directly to row numbers, I can't think
of any other changes offhand.
Or am I all wet and this is not a bug? Please respond to me directly, as
I'm not a member of this list.
