Greetings,
I am new to this list. I have a problem with BLOBS using PostgreSQL7.3.4.
I used the lo_export utility to insert an image into a trial database. I have
not been able to use the lo_export utility to retrieve it. I have done this
successfully before using PostgreSQL7.2.
Assuming I have a table name TABLE with columns named TITLE and IMAGE. I (
working as postgres ) issued the following select statement :
SELECT lo_export(table.image('/tmp/outimage.jpg')
from TABLE
where TITLE ='First Picture';
I get in response 'cant open unix file system "/tmp/outimage.jpg" no such
file or directory. The problem seems to be the filename. So I tried
different filenames such as image2.jpg, etc with the same result.
I looked at the /tmp directory and I did not see any jpegs. I also looked
at the postgres/data directory to see if there is a directory labelled /tmp.
I was unsuccessful. I am using a PC running SuSE8.2.
Some help will be appreciated.
Yours sincerely
Sibu
