Getting oid with libpq

Hello,

 

I have stored some large objects (which are images) with the lo_import function. Now I can read the images with the other functions like lo_read within libpq. But I have one problem with the oid I have to give to this method. Inside my program I will do a select like this

 

Select texture from building_face where face_id > 100;

 

Textures is the oid field. When I use PQgetValue() I get a complete different value then when I do  a select inside pgAdmin. How can I get the same oid so that I can use this for reading the data of the images inside my c++ program. Because it is not working with the oid from PQgetValue.

 

Best regards,

 

Johan de Koning
