inet datatype question!

От
Дата:
Hi all!

Can you help me with the following problem?

I have created a table:

CREATE TABLE(
src inet,
dst inet,
size int);

How can I insert an ip address or a network address into src or dst within
a Java program, using a Postgresql JDBC driver? - Which method to use? -->
setXxx?
Thank you very much!

Hi,

Unfortunately java doesn't have a "type" that corresponds to the
postgres inet type. You can retrieve it as a string however. Use
getString. Of course you will have to parse the string.

SocketException: "catch me if you can"

I am using a JDBC connection over a PPP connection layer. The pgsql-jdbc
driver throws a SocketException and the databse connection dies. I
consider the ppp layer to be "suspect", but at least it survives this
hiccup. Is it (1) possible (2) a good idea to beef up the driver to handle
this situation? Or should my application logic handle this?

BTW- I'm using the cygwin port of postgresql and therefore I'm using
microsft's dialup software ('rasdial', blech)

Thanks,
Mike Adler
