Restoring a table with blobs - Without doing a full restore - Is it even possible ?

Hello !

I have a table that is created as follows

Create Table file_200 (Record_number integer, Customer_Image OID;
CREATE UNIQUE INDEX file_200_Record _Number_Key ON file_200
(record_number) ;

I store pictures using (In Delphi 7)

PSQLImageQuery. Edit;
PSQLImageQueryc ustomer_image.L oadFromFile('c: \tmp.jpg');
PSQLImageQuery. Post;

Everything works just wonderfully, even a full dump and restore works
like a charm (Using pg_dump, pg_restore).

Now, of course thats not good enough..hehe. I need to be able to make
a partial restore of the picture table only (there are about 30
diffrent tables, it is not a huge database, 30MB compressed tar.gz). I
tried using the pg_restore -t flag and it runs threw with no errors.
The problem is that the pictures are simply not there and I can not
even overwrite them with new ones. Also, the index is not restored.
When I load the pictures I simply do a "where record_number=# #" query
and then the DBImage component does the rest.

I am using PSQL 7.2

Any ideas ?

Thanks a lot

I'm trying to restore a backup from a DMS DB2/2 database. The original DB has 3x 1Gb containers in the user tablespace. So the backup has 3 files, bearing the time of the backup as file name, with extensions ..001, .002 and .003. The files are placed into a d:\dbname.0\db2.0\yyyymmdd directory tree, as does DB2/2 when performing the backup. I created a similar DMS 3x1Gb DB on another machine for the restore. But when I launch: db2...

I have a 600K row table on my production system (running 7.3.3) that I dump and load on my development system (7.4.1) every night using cron jobs. I would like to be able to restore the table under a different table name without first having to play games with the development copy of the table. If I edit the dump file with 'sed' to change the table name, I get 'invalid command \N' errors trying to reload it.

Hello, I have a problem restoring Exchange 2000 files. Our software has an interface to ESEBCLI2.dll for online backup and restore features.

Hello, Every so often, I'm asked to help people recover data from tables that were either dropped or where to much data was DELETEed. The complications related to restoring data are a problem. The SAS users are laughing because they can (to a certain extend) easily go back to an earlier SAS table by simply starting dsm. Of course, a flat file table is different than a relational table; but still, the trouble related to restoring DB2...

I'm working on a restore procedure for the case where all MDF files are missing, but the LDF files are all intact. A full backup is done every 24 hours, and a log backup is done every 3 hours.
