Hello,
I tried to insert an image in my database with lo_import. The error I
get is "invalid large object descriptor: 0". If I try to create an oid I
get a valid one but with lo_import it seems not to work. The connection
is ok as well.
The folloing code produces the output after the code.
if (PQstatus(connDB) == CONNECTION_OK)
std::cout << "CONNECTION_OK" << std::endl;
Oid oid = lo_creat(connDB, INV_READ | INV_WRITE);
std::cout << oid << std::endl;
std::cout << PQerrorMessage(connDB) << std::endl;
std::cout << lo_import(connDB, "/tmp/image.vtk") << std::endl;
std::cout << PQerrorMessage(connDB) << std::endl;
Output:
CONNECTION_OK
25211
0
FEHLER: ungültiger Large-Object-Deskriptor: 0
Here is the version string of my db:
PostgreSQL 8.3.3 on x86_64-redhat-linux-gnu, compiled by GCC gcc (GCC)
4.3.0 20080428 (Red Hat 4.3.0-8)
Can anyone tell me please what is wrong?
Thank you,
Markus
