I was wondering if anyone had any working sample code of inserting a blob
into a table and then retrieving one from a table for viewing?
I'm using Postgres 8.2, the jdbc is postgresql-8.2-504.jdbc3, and the Java
is 1.6.
I'm also running on a Windows XP Pro box if that matters.
Thanks,
Marc

So turning to Postgresql, can I get any recommendations, suggestions and
tips on blob handling in the database? The image sizes will be pretty
variable, from a few kilobytes to several hundred megabytes, so I need
something that will handle the various file sizes, hopefully transparently.

Thanx for ur suggestion... But I face a new problem
now...
connection.setAutoCommit works well with postgresql
7.3 .. but with postgresql 7.4 I am getting the

Error in connection == ERROR: SET AUTOCOMMIT TO OFF

I have tried pg73jdbc1.jar and pg73jdbc3.jar .. both
Thanks a lot for the clue... Now I am comfortably
handling the Lrge Objects thru SQL...
But unfortunately I could not extract this data to
frontend thru java... I tried in two ways but got the
same error...after getting the data in Blob or Large

That's a good discussion, but it left out at least one useful bit of
info about managing large objects: there's a contrib utility
(contrib/vacuumlo) that can find and remove large objects that are not
referenced anywhere in the database.

When you dump a database with the BLOBs, even with the -c option, and then
restore that database again with the -c option, you get double the BLOBs.

Hi,
In june, I had to migrate a web site using paradox tables on a winNT to
a Linux box. I had chosen first postgresql 7.0 for its solid-based
features.
But unfortunately, when I started to migrate my tables, a problem raised
: the implementation of blobs in Postgre. My tables stored lots of
I recently ran into a big problems regarding blobs and rollback with postgreSQL 6.5.3
A table contains many entries and each entry includes a single
blob-oid. In a databaseprocessing perlscript I need to delete such a
blob and perform the lo_unlink and later I rollback the session without
