Обсуждение: best way to use bitvarying?
Hi all, We would like to store *small* images into bitvarying fields. These will then be read in via jdbc and eventually rendered in a browser. What is the best way to pull them into Java? Is there a type and methods that are best suited for this data type? Currently, we are using text and treating it as a string of 0's and 1's. Any suggestions for a better way? Thanks for your help, -- Laurette Cisneros (510) 420-3137 NextBus Information Systems, Inc. www.nextbus.com Passenger Information Everywhere select count(*) from blessings;

Last I was hearing (see http://lab.applinet.nl/postgresql-jdbc/#Lob) "bytea is currently unsupported in the jdbc interface". Is this not true for 7.2? Is there a suggested way of using this with jdbc? Thanks for the help, L.

Laurette, bytea is supported in 7.2, and the 7.2 drivers will work against either a 7.1 or 7.2 database. You can download the latest 7.2 drivers from jdbc.postgresql.org. thanks, --Barry Laurette Cisneros wrote: > Last I was hearing (see http://lab.applinet.nl/postgresql-jdbc/#Lob) "bytea > is currently unsupported in the jdbc interface".
