If you can read say tens or hundreds of records then the first method is
better. Not oveload server memory and is quickly.
But if you can read thousand or more records then is better to use other
methods.
[open connection]
[open temporary file]
[loop thru recordset]
[write to file]
[end loop]
[close connection]
[close file]
[open file]
[loop thru lines]
[print to html]
[end loop]
[close file]
By my experience all servers have less RAM then disk space ;-) and read or
write text file is a simple task for server.
