Can mysql_fetch_*() work on the resultpointer only?

Hi - Can mysql_fetch_*() work on the resultpointer that mysql_query() returns, only, or does the rows have to be in the database when fetching? I know that mysql_query() finds the specified data, but I'm not totally sure in my theori about that mysql_query() is taking the data-result out so that we're not depending on the database anymore. -- Mvh./Best Regards Jonas Delfs, http://delfs.dk "Developers are being asked to do more with less, do it faster, and make it fit with the existing systems and databases." - IDC
