You don't mention what language and interface you're using but it sounds like C and libpq. > Is there any function in postgresql which gives the return value of > the executed query as OID type. You could rely on the knowledge that Oid is typedef unsigned int Oid; and use strtoul() to convert the char * to an unsigned int. Another way, if you're using 7.4 or later, would be to issue the query with PQexecParams() and request binary results. I think you'll have to deal with byte order issues in that case. This is off-topic for pgsql-admin; pgsql-interfaces or pgsql-general would be more appropriate. -- Michael Fuhr
