Thread: Fw: Unable to open PostgreSQL large object
Once again I am having difficulties with large object. I was finally able to get all my functions and triggers straightened out but now I can't seem to open the large object. Since the last time I was able to open the large objects I have changed my operating system to Linux8. I'm using Postgresql 7.3.2 and php 4.3.1.
I found one person who has posted the same problem http://archives.postgresql.org/pgsql-general/1999-06/msg00322.php. He used the following solution:
<solution>
"After I updated to LinuxPPC R5 I had to recompile Postgres to use glibc2...
and the compiler with R5 is egcs 2.91.66. After getting some help from the
Postgres mailing list it turned out that the linux_ppc template needed to
change the compiler optimization flags from CFLAGS:-O2 to -O0. Then it ran
without problem, but before then I had many "oid" errors."

If I need to change my linux_ppc template I probably need some help on how to do that. Or some ideas on what else I can try.
This is the code I used to try and open the large object:
<my code>
pg_exec ($db, "begin transaction");
$handle=pg_loopen($db,$row['signature'],"r"); //also tried with assigning the array value to a variable
$bitmap=pg_loreadall($handle);
echo substr($bitmap, 17);
pg_loclose($handle);
pg_exec ($db, "end transaction");
$handle=pg_loopen($db,$row['signature'],"r"); //also tried with assigning the array value to a variable
$bitmap=pg_loreadall($handle);
echo substr($bitmap, 17);
pg_loclose($handle);
pg_exec ($db, "end transaction");
</my code>
Any help would be greatly appreciated.
Thanks.

Try the following: $results = pg_query($db,"Select some_image from table"); $row = pg_fetch_array($results); //Header( "Content-type: jpg"); echo stripcslashes($row[0]); Patrick Hatcher Macys.Com |--------+---------------------------------> | | "Juliet May" | | | <jmay@speark.com> | | | Sent by: | | | pgsql-novice-owner@post| | | gresql.org | | | | | | | | | 05/22/2003 03:04 PM | |--------+---------------------------------> >----------------------------------------------------------------------------------------------------------| | | | To: <pgsql-novice@postgresql.org> | | cc: | | Subject: [NOVICE] Fw: Unable to open PostgreSQL large object | >----------------------------------------------------------------------------------------------------------| Once again I am having difficulties with large object.
