The question is: Can I in function: int PQputCopyData(PGconn *conn,const char *buffer,int nbytes); use as a result buffer directly given by using PQexec for SELECT SQL command ? In other way: Is the structure given as result of PQexec with SELECT SQL command directly usable as buffer for PQputCopyData ? Brgds Adam ^ permalink raw reply [nested|flat] 2+ messages in thread
