J. Random,
I have implemented network datatype extensions for the JDBC driver. This includes PGcidr, PGinet and PGmacaddr, they
areavailable from the following URL.
http://oak.cats.ohiou.edu/~rf358197/jdbc/2/
They should be pretty easy to use and if you find any defects I am more than happy to fix them. I would love to see
themintegrated into the base driver at some point and am willing to make any modifications which need to be made to
facilitatethis. Hopefully they will be of some use to you.
Kind Regards,
Russell Francis

Subject: [JDBC] User Defined Types -- Using inet/cdr from JDBC ?
Hi all:
I have recently released my O/R mapping tool (molly)
at:
www.mollypages.org/dbo
Currently, this tool does not support any postgres
specific types.
So, when doing the O/R mapping, if the JDBC Meta Data
returns:
java.sql.Types.OTHER (1111),
the O/R tool gives up and says:
----
Exception in thread "main" java.sql.SQLException: This
framework does not understand/support columns of this
type. [java.sql.Type: 1111]
-----
Ok so far, so good (or bad). But now I do have a need
to use:
1) inet, cdr types
2) point, circle etc types
Suppose, I have:
create table test (my_ip_address inet);
Looking over the JDBC docs, I see that I may to say
something
like (in java):
1 ResultSet rs = stmt.executeQuery("select * from
test");
2 Map map = new HashMap();
3 map.put("inet", foo.class); //string -> user
defined class
4 rs.next();
5 Object o = rs.getObject(1, map);
The program does not get too far. I get:
Exception in thread "main"
org.postgresql.util.PSQLException:
Method
org.postgresql.jdbc3.Jdbc3ResultSet.getObjectImpl(int,Map)
is not yet implemented.
Any comments on the current/future ability to use
inet/cdr
types in this way ? I'm guessing I can instead use
PGpoint etc., but
what about inet/cdr ?
Best regards,
--j
