Hi Macro.. If i assign my lobj_fd(say LO file descriptor) to one Global int. But will my lo_write work if i pass that global int inplace of lobjfd.... One more thing...It should be in "begin" and "end" sessions right! How can i open a LO in many places and write the content into it.....Will it get appended to the previous content? You said two different file descriptors i will be having?How to overcome it?Any suggestion pls Anybody please give me suggestion how can i over come this problem?So that i can proceed further ----- Original Message ----- From: "Marco Bizzarri" <marco.bizzarri@xxxxxxxxx> To: "sandhya" <sandhyar@xxxxxxxxxxxxxx> Cc: "Postgres" <pgsql-admin@xxxxxxxxxxxxxx> Sent: Thursday, June 22, 2006 1:43 PM Subject: Re: [ADMIN] reg:lo_write > I'm not sure, but I think you will have problems.
